This document discusses a new model for analyzing maximum velocity sprinting mechanics compared to the traditional three-phase model of drive, swing, and lift. The new model focuses on six areas: body position, recovery mechanics, transition phase, ground preparation phase, ground phase, and arm action. It analyzes each of these areas in detail using video of world-record sprinter Asafa Powell and argues the new model provides a better understanding of generating and maintaining high speeds.

Una teoria dell’allenamento basata sui principi della fisiologia del movimento, con particolare riferimento all’allenamento infantile e giovanile
L’allenamento ottimale di Juergen Weineck è il classico per eccellenza della teoria e scienza dell’allenamento e, da oltre quattro decenni, rappresenta uno dei principali testi di riferimento sulla materia, in tutta Europa e non solo.
Le varie edizioni del trattato sono state rese in più di quindici lingue e questa terza edizione italiana (sulla diciassettesima edizione originale) rimarrà certamente ancora per anni un cardine essenziale della letteratura specialistica internazionale.
Il lettore troverà, dettagliatamente esposti e doviziosamente collegati alla produzione scientifica mondiale, davvero i più recenti e, ad oggi, ancora insuperati sviluppi della scienza dell'allenamento, e, avvalendosi dell’orientamento pratico dell’opera, avrà la possibilità di applicare, facilmente e direttamente, i progressi scientifici alla pratica quotidiana di allenamento ed esercizio.
Juergen Weineck ha riversato e assai ben illustrato e descritto le diverse metodologie di allenamento utilizzate nel mondo e la loro efficace concreta applicazione, con focus sui fondamenti e sui collegamenti medici e fisiologici della prestazione. Un’attenzione particolare è stata dedicata ai problemi specifici dell'allenamento di resistenza e dell'allenabilità in generale nel contesto della formazione motoria e dell'allenamento per bambini e per giovani.
L'autore, partendo dall’allenamento delle principali capacità che caratterizzano il movimento umano (resistenza, forza, velocità, mobilità articolare, capacità coordinative) e da alcuni fattori specifici della prestazione, offre una quantità immensa di suggerimenti sull’ottimizzazione dell’allenamento sportivo, rivolti ad

This document outlines a coaching philosophy and systematic approach to training athletes. The philosophy focuses on developing well-rounded athletes and people through positive relationships and teaching the purpose behind training. The training approach assesses needs based on sport demands and implements a sequenced plan including testing, soft tissue work, activation, warm-ups, plyometrics, movement drills, Olympic lifts, strength training, conditioning, and recovery work to enhance performance and reduce injuries. The goal is to teach efficient movement patterns specific to each sport.
Speed requires explosive force applied to movement. Agility requires changing direction and speed rapidly through forceful eccentric and concentric muscle actions. Speed-endurance maintains high speed over time through repeated high acceleration bouts. Proper training focuses on increasing impulse and rate of force production, and improving eccentric strength. It utilizes primary exercises with proper technique at increasing intensities, and secondary resisted and assisted methods, within programs manipulating variables like interval, intensity, and recovery period.

Physical Condition, Physical Skills and Ways to improve them 3º ESO SeccionesCiclos Formativos
The document discusses various components of physical fitness including endurance, strength, speed, and flexibility. It describes the different types of endurance training including aerobic, anaerobic, speed and strength endurance. It discusses how to develop these components through various training methods like interval training, weight training, circuit training and more. The document also discusses strength training and its effects on the body, as well as how to develop speed through techniques like reaction speed drills and acceleration training.
This document provides guidance on analyzing an athlete's performance power through movement analysis and identifying the predominant energy systems used. It discusses the differences between strength, speed, and power. Power is defined as force multiplied by velocity. The force-velocity curve is examined in selecting different loads for training. Alternatives to Olympic lifting like kettlebell swings and sled pushes are suggested for developing triple extension. Session considerations include a complex training method, exercise selection and order, load, reps, sets, rest, and potential power exercises.
This document provides an overview of strength and conditioning for futsal players. It discusses the importance of developing work capacity, taking an individualized approach, testing players regularly, and training the core, VO2max, speed/agility/quickness, and injury prevention. The author recommends a periodized plan that progresses from general preparation to sport-specific conditioning and emphasizes tactical/metabolic training, nutrition, and balancing all aspects of conditioning for futsal.
Speed is the quickness of movement in sports and can be expressed as maximum speed, power, or speed endurance. Speed is influenced by factors like muscle structure, strength, technique, and energy systems. There are different types of speed like reaction speed, speed of movement, acceleration speed, sprinting speed, and speed endurance. Speed training involves drills, sprints of various distances, uphill and downhill running, and overcoming the speed barrier through indirect training when direct speed work plateaus. A sample speed training week alternates weight training, short speed workouts, and long speed workouts.
The document provides an overview of functional training principles including:
- Functional training methods are based on specificity across mechanical, coordinative and energetic domains.
- The functional pyramid outlines the progression from basic movements to sport-specific skills.
- The 5 principles of training are specificity, overload, progression, reversibility, and avoiding tedium.
- Training load, intensity, volume, and their balance are important concepts for periodizing training plans.
- Applications include assessing mobility, stability, and kinetic patterns to design training for different periods.
Strength & Conditioning Training for NetballJon Renes
This document discusses strength and conditioning training for netball. It outlines the five "S's" of sport that should be trained: skill, speed, suppleness, strength, and stamina. Benchmarking tests are recommended to establish baselines and set performance goals. A high performance training program is described, emphasizing specificity, progressive overload, and periodization over 10,000 hours of training across 10 years.
Melhorar ou até mesmo manter o desempenho atlético em jogadores de esportes de equipe competitivos durante o longo período da temporada é um dos maiores desafios para qualquer treinador comprometido. Tempo muito limitado está disponível entre as partidas semanais para introduzir sessões intensivas de treinamento de força e poder, com uma freqüência normal de 1-2 unidades por semana. Este fato estimula a busca de métodos de treinamento mais eficientes capazes de melhorar uma ampla variedade de habilidades funcionais, evitando ao mesmo tempo os efeitos de fadiga.
This document discusses key concepts related to developing effective training programs, including training principles, methods of training, exercise physiology, and applying the FITT principle. Some main points covered are the importance of periodization, progressive overload, and specificity in training to optimize performance improvements over time through chronic adaptations to exercise. Both acute physiological responses and long-term training effects on the body are addressed.

AND THE COMBINATION OF THESE
2 ELEMENTS.
Olympic weightlifting has numerous benefits for improving athletic performance. It develops strength, power, balance, coordination, and other physical attributes through explosive multi-joint movements like the snatch and clean and jerk. Research shows these attributes transfer well to other sports and that Olympic weightlifting is an effective training method for athletes of various ages when incorporated appropriately. The document provides definitions of the lifts and derivatives and discusses how Olympic weightlifting fits into models for long-term athlete development.
Speed training can be broken down into starts, accelerations, and maximal velocity. Starts should focus on modified standing positions from various angles to mimic game situations. Accelerations should include drills from both static and dynamic positions over 10-25 meters. Maximal velocity training should focus on optimal form over 30 meters that allows for rapid changes in direction rather than high knees. Proper progressions and measuring performance can gauge training effectiveness for the components of speed training tailored to individual sports.
The document introduces the Real Running program which teaches runners to adopt the Pose Method of running developed by Dr. Nicholas Romanov. The Pose Method focuses on proper running form consisting of three key elements - pose, fall, and pull. Most recreational runners heel strike which leads to injuries. The Real Running program uses the Sproing Runner machine and running drills to teach runners to forefoot strike and harness gravity to run more efficiently with less impact through adopting the optimal running form outlined in the Pose Method.

This document summarizes various performance testing and monitoring protocols used at the Lake Placid Olympic Training Center to assess athletes' body composition, strength, power, speed, balance, and stability. Measurements include body mass, height, skinfolds, girths, bone widths, body fat percentage, isometric mid-thigh pull force output, vertical jump power and contact time, gait analysis, sprint times, and positional sway. Regular monitoring of these metrics allows coaches to track changes, identify asymmetries, gauge injury risk, and optimize training plans to improve athletes' performance.
Muscle monitoring for optimal rehabilitation & sports performancePetri Lehikoinen
1) Muscle monitoring using EMG during rehabilitation and training can provide valuable feedback to optimize recovery and prevent re-injury. It allows assessment of muscle balance, activation, relaxation and quality of movement.
2) A case study of 4 athletes recovering from ACL injuries found that EMG monitoring helped identify issues like lingering hamstring imbalance and informed changes to training programs. All athletes showed improved muscle balance over the course of rehabilitation.
3) EMG data collected from a skier during isokinetic testing, sprints and sports-specific drills provided insights into eccentric strength deficits and activation asymmetries to target in training, helping enable a safe return to competition after ACL reconstruction.

The document provides an in-depth biomechanical analysis of sprinting technique. It discusses key concepts like impulse, stride length, frequency, and leg and arm action. Some main points:
1) Impulse is the foot-ground contact force over time and defines how the body produces linear movement. Proper force application results in increased stride length and frequency.
2) Stride length consists of takeoff, flight, and landing distances. Factors like takeoff velocity and angle of projection determine takeoff distance.
3) Stride frequency alone does not cause speed; force application to the ground through proper technique increases both length and frequency.
4) The stretch reflex and knee cycling aid the recovery

ABSTRACT
The most widely used technical model of the running stride comprises three
phases: the Drive, the Swing and the Lift. However; using this model, and
emphasizing the development of strength to meet the aim of applying more force
to the ground, many coaches neglect the neuro-physiological aspects of sprinting
technique and may limit their athletes' performance in the. Maximum· Velocity
Phase of the 100 meters, known as the key to success in the event. A more
contemporary model, taught in the IMF Coaches Education and Certification
System and demonstrated by the world's fastest sprinters, provides better
understanding of high speed running mechanics and the implications for
generating and maintaining greater maximum velocity. According to the authors,
this model can be developed using six reference points or foci: Body Position,
Recovery Mechanics, Transition Phase, Ground Preparation Phase, Ground
Phase, and Arm Action. With video captures of former world record holder Asafa
Powell (JAM) in competition to illustrate their points, they discuss each of the foci
in detail. They also explain how the quality of any phase in the cyclical movement
of the sprinting stride is determined by the quality of the phase that immediately
precedes it. They conclude by stating that retaining the traditional model limits
the performance potential of the athlete.
Introduction
It has been repeatedly demonstrated that the level of velocity attained and
maintained during the Maximum Velocity Phase of the race is the factor most
highly correlated with performance and success in the 100 meters. Quickly
reaching a high velocity and then holding it through the finish line is possible only
through a combination of very efficient acceleration and superior execution of
high-speed running mechanics.
2. Aristotle is said to have made the observation that animals move by pushing
against the ground beneath them. So the recently touted notion of the importance
of the ground phase of the stride cycle in sprinting is not news by any means.
Being able to apply more force to the running surface in less time has always
been a key aim in sprinting.
For many coaches, the preferred way to accomplish this aim is for the athlete
to "get stronger". However, while strength certainly contributes to the capacity to
generate power, this approach falls woefully short of explaining how a great
amount of force can be generated in the proper direction and through an optimal
range of motion in the very short periods of ground contact, often times less than
100 ms, in the sprint stride.
Power is a combination of strength and neuro-muscular coordination (NMC),
with NMC representing neuro-physiological concepts such as motor unit
recruitment by summation, order and sequence of recruitment, inter and
intramuscular coordination and synchronization. Speed, on the other hand, is a
combination of power and neuro-muscular coordination again, but here NMC not
only applies the above-mentioned physiological constructs but it also follows
principles of motor learning, which effect changes in the athlete's technical
model. In common coaching parlance NMC is often used, in this later instance,
synonymously with technique.
The most widely used technical model of the running stride comprises three
phases: the Drive, the Swing and the Lift. It is safe to say that this has been
ingrained in most athletes. At the 2008 European Athletics Coaches' Association
Congress in Glasgow, Scotland, this long-used conventional model was
contrasted with a not so new, but still not widely understood, model of high-speed
running that is taught in the International Association of Athletics Federations
(IAAF) Coaches Education and Certification System. It was suggested that the
use of the Drive-Swing-Lift model places a ceiling on a runner's ability to
generate very high velocity in the critical Maximum Velocity Phase of the 100
meters. This speed barrier may limit performances to the low ten-second range
for male sprinters.
This article addresses the issue of how athletes can break through this barrier
by providing a description of the more contemporary alternative technical model
of high-speed running. It is presented in the belief that athletes can achieve
consistently faster performances by applying a better understanding of the
mechanics of high-speed running and the implications for generating and
maintaining greater maximum velocity. This belief is supported by the fact that
the model is clearly exhibited by the world's fastest sprinters.
The high-speed running model applies generally to all running and jumping
disciplines. There are differences in the specific models used in each event, but
they are very few and are related to the velocity. In most cases, they are
3. differences in the speed, intensity and amplitude of the movement.
The six foci of high speed running
The main emphasis in this article is on the 100 meters and in particular on the
Maximum Velocity Phase, which represents the portion of the race when the
athlete is moving fastest over the ground. In the 100 meters, the athlete is
seeking his/her absolute maximum velocity in this part of the race. In longer
events, the athlete, at some point in the race, achieves his/her highest speed for
that distance, even though it may not be his/her absolute maximum running
velocity. It is important to be aware that any velocity between 95 and 100% of the
athlete's absolute maximum employs identical mechanics.
If athletes are to change their motor patterns for high-speed running
mechanics and thus improve their mechanical efficiency in this key part of the
race, they must develop a sound conceptual technical model. The new model
must be introduced, rehearsed and refined. It must then be continually reviewed.
In evaluating and teaching high-speed running mechanics, the coach must
give the athletes key points on which to concentrate and consciously focus as
they learn to re-programme their motor patterns. It is useful to break down the
movement in a way that is consistent with a systematic teaching progression. We
use six reference points or foci for developing the conceptual technical model, in
the teaching progression employed, during video analysis to identify faults and
causes, and in making corrections. These six foci are:
1. Body Position - This is the most central focus for changes in the technical
model and thus for improving performance. If the athlete cannot execute the
correct body position with a high degree of proficiency, it is nearly impossible to
optimize the other five foci. Conscious competence in this area must quickly give
way to unconscious competence.
2. Recovery Mechanics - This is the first phase of the high-speed running
cycle movement. Often thought of as a passive movement and traditionally called
the "swing phase", the mechanically efficient recovery of the limb sets up the
other phases of the running stride for higher levels of mechanical efficiency.
3. Transition Phase - This is the phase of the running cycle where an abrupt
change of direction of a limb must take place. Faults are often easily recognized
in this phase, but they are almost always a product of a cause that is 180° on the
other side of the stride cycle.
4. Ground Preparation Phase - This is the phase where the athlete must
actively prepare the foot and the leg to strike the ground. From the point of view
of determining the performance outcome, this is the second most important
phase in the running cycle.
4. 5. Ground Phase - This is the most important phase in the running cycle. Once
the athlete leaves the ground, the flight path of the centre of mass is unalterable
until the next ground force application. Therefore, getting the Ground Phase right
is essential.
6. Arm Action - This is the focus that has provoked some of the greatest
disagreements between biomechanists and coaches. Biomechanists have
contended that the arms balance the forces of the legs to maintain the body in
the proper alignment. Coaches on the other hand have promoted that the arms
"control the legs" and thus can positively impact performance. Is it possible that
both points of view may be correct?
In the following sections, each of these foci will be discussed in detail using
video captures of former 100 meters world record holder Asafa Powell (JAM) in
competition to illustrate our points.
Body Position
Body position has three distinctly different components: core stabilization,
postural repositioning and control, and vertical (longitudinal alignment). Each
must be perfectly executed in order to facilitate a highly efficient motor pattern. If
one of the three is executed less than optimally, the overall performance will be
less than optimal.
Core stabilization
This has become a buzzword (two words, actually) in the human performance
industry, and with good reason. Without a stable core, the body segment that
comprises the area inferior to the rib cage and superior to, but including, the hip
joint, the athlete cannot generate significant ground forces without leaking
energy. One must be able to draw-in and brace in this area so that force will not
be absorbed in the many articulations that exist in the core.
Draw-in refers to engaging the investing abdominal musculature; the
transverses abdominus, internal and external oblique muscles as well as certain
segments of the rectus abdominus. The aim is to decrease the volume of the
intra-abdominal compartment. Think of making yourself "skinny" so you can
button that tight pair of blue jeans you used to wear ten years ago.
Brace refers to stabilising the vertebral column and pelvis not only in the
saggittal plane, but also in the frontal and transverse plane. In practice this
means two things. The distance from the xyphoid process and the symphonies
pubis must remain constant and the vertical alignment of the xypoid process and
symphonies pubis must not deviate laterally because of lateral bending in the
5. frontal plane of rotation in the transverse plane.
Postural repositioning and control
This is necessary to place the musculature that crosses the joints of the core
in an optimal length-tension relationship. Often, athletes will exhibit an anterior tilt
of the pelvis (pelvis looking down) but the objective here is to reposition the
pelvis into a neutral position (pelvis looking up) (see Photo 1).
The neutral pelvis places the hip flexors in an ideal length tension relationship
to store elastic energy and produce force during thigh recovery. This neutral
position also facilitates the initiation of the triple flexor response. Both factors
assist in reducing the time required to recover the limb through optimal range of
motion. The anterior tilt shortens the hip flexors, rendering them less efficient and
switches off the triple flexor response. The consequence is seen in the leg
lagging behind the body. This also has implications affecting the efficiency of the
ground preparation phase affecting the hip extensors.
Vertical (longitudinal) alignment
With the execution of draw-in and brace and postural repositioning of the
pelvis, the athlete must position the shoulders above (or on top of) the hips (see
Photo 2).
6. This maintains the optimal length tension relationship of the hip flexors, which
then facilitates storing elastic energy and producing force as well as allowing
better a triple flexor response. The main fault is as follows: during high-speed
running, with the proper draw-in and brace and pelvic repositioning the athlete
may still produce a closed chain flexed position at the hip. This shortens the hip
flexors. The cause may be that the athlete has a faulty conceptual technical
model in that someone may have told him/her that there must be a "forward
lean", and this may be how the athlete perceives the movement must be
executed. Alternatively, the athlete's hip flexors, either individually or collectively
may be hypertonic, thus producing compensation. Finally, the athlete may not be
capable of maintaining a draw-in and brace and neutral pelvis without this
compensation.
Note that it may be more correct to describe the alignment as "longitudinal".
When we discuss acceleration mechanics, the shoulder must fall in alignment
with the hip on the power line and is not really vertical to the hip.
Principles governing quality of movement
It is well known that in any cyclical movement, the quality of any phase in the
movement is determined by the quality of the phase that immediately precedes it.
Let us clearly delineate the difference between the terms "intensity" and "quality".
Intensity is a percentage measure of maximum. Quality on the other hand can be
7. discussed as a percentage measure of perfect. When we discuss the phases of
the running cycle we must look at the quality or how perfectly and mechanical
efficient a movement is executed and not just at the intensity of the movement
realized. In the case of our six foci we can also apply this statement to body
position. If body position is not perfectly executed, then it is impossible to
correctly and perfectly execute any other phase of the cyclical movement.
It is stated above that the most important phase of the running cycle is the
Ground Phase. Therefore, it would hold that if your aim is to produce a high-
quality Ground Phase then you must have a high-quality Ground Preparation
Phase. The aim then becomes the execution of a high-quality Ground
Preparation Phase. However, this depends on a perfectly executed Transition
Phase, which in turn is predicted by perfectly executed recovery mechanics. (It
also holds true that high-quality recovery mechanics must be preceded by a high-
quality Ground Phase. This must be the case because the running movement is
cyclical.)
Therefore, to develop a teaching progression from a movement analysis
standpoint, we must begin by making modifications in the quality of the recovery
mechanics, which will in turn positively affect the Transition Phase, the Ground
Preparation Phase and ultimately the Ground Phase.
Recovery Mechanics
Recovery mechanics comprises two distinct phases: the Residual Phase and
the Recovery Phase.
Residual Phase
The Residual Phase begins at take-off and concludes when the thigh begins to
accelerate in a positive (forward) direction. One can think of it as what is left over
from a high quality force application in the Ground Phase. This phase represents
the best opportunity to realize a reduction in the time required to recover the limb
through the optimal range of motion.
However, at take-off, the hip joint frequently continues to extend. This is a result
of the athlete attempting to continue accelerating the thigh through the entire
Ground Phase and not prematurely decelerating the thigh. To achieve one of the
two parts of the sprinter's mission statement: "to reduce the amount of time
required to recover the limb through an optimal range of motion", the athlete must
re-programme the nervous system. Two cues assist the athlete to focus
attention. First, maintaining proper body position allows the length-tension
relationship to be optimal, thus allowing greater force potential from the hip
flexors and a greater efficiency in producing elastic force to initiate thigh flexion.
Second, and more important, is the cue "toe-up". With the proper body
8. position, ankle dorsiflexion allows the initiation of the triple flexor response (see
Photo 3 and Photo 4).
The timing of the dorsiflexion message to the anterior compartment muscles is
of critical importance. MOUCHBAHANI et al. demonstrated that the dorsiflexion
message was sent sooner in faster sprinters and much later in slower sprinters.
The fastest sprinters showed EMG activity over the anterior compartment as
early as mid-stance (when the centre of mass is over the base of support). This
finding further validates the concept of anticipatory firing or reprogramming the
athlete's nervous system to send the dorsiflexion message sooner.
Recovery Phase
The Recovery Phase begins with the positive acceleration of the thigh. The
aim here is to maximize thigh acceleration and therefore reduce the amount of
time to recover the limb through the optimal range of motion. To this end, use of
stored elastic energy in the hip flexors and realizing a low moment of inertia
(resistance to angular acceleration) of the thigh are essential.
To minimise the moment of inertia of the thigh, it is critical for the athlete to
make the leg as short as possible, as soon as possible. This means that high
angular acceleration values must be realized at the knee joint. Dorsiflexion of the
ankle joint accomplishes both these tasks. Occurring actively at take-off,
dorsiflexion facilitates the triple flexor response. In addition, it facilitates knee
9. flexion by the gastrocnemius. Use of stored elastic energy in the gastrocnemius
and its high contraction velocity makes it possible to generate high values of
angular acceleration at the knee joint. The result is a short lever as soon as
possible.
The ankle remains in dorsiflexion, which maintains a small knee angle
throughout the entire Recovery Phase (see Photo 5, Photo 6 and Photo 7).
10. Note the relative position of the thighs at the instant of touchdown. In
mechanically efficient high-speed running, the knees will be together with the leg
folded such that the calf is pressed tightly against the hamstring, at the moment
11. of touchdown (no intra-thigh angle). Reducing the time required in the Residual
Phase and the first part of the Recovery Phase represents the only opportunity to
reduce air time. This is the case because once touchdown occurs (where the
knees should be level) the next ground phase begins (see Photo 8).
The Recovery Phase ends with an abrupt deceleration of the thigh at optimal
hip flexion. The ankle must stay in dorsiflexion and the knee must maintain
flexion such that the toe remains posterior to the knee. This insures the lowest
moment of inertia values and continued angular acceleration of the thigh until the
thigh is blocked. If this position is maintained then the athlete will exhibit an
action that has been called "stepping over and around the opposite knee." In
events that require lower velocities, athletes will exhibit less intense recovery
action, thus stepping over the opposite calf.
Transition Phase
The Transition Phase begins with the abrupt deceleration of the thigh. Blocking
of the thigh corresponds with take-off on the other leg. Blocking the thigh allows
the sprinter to transfer the momentum generated by rapidly accelerating the
mass of the thigh into the body as a whole and therefore unloading the weight of
the body. If this is accomplished efficiently, the result is that the force generated
at take-off yields a greater vertical and horizontal projection of the centre of mass
because the weight of the body is "less". This in turn produces a greater effective
12. stride length (air distance). Transition ends with the negative acceleration of the
thigh.
Not infrequently, it appears that a sprinter will float, almost statuesque, with the
thigh positioned in the optimal flexion position of the Transition Phase. This
prolongation works against reducing the time required to recover the limb through
optimal range of motion and return the limb to the ground for the next force
application.
Note: a prolonged Transition Phase is often the result of a prolonged Residual
Phase. The legs work like scissors. The thigh cannot be accelerated in a
negative direction without the thigh of the other leg being accelerated in a
positive direction. After all, the quality of the Transition Phase is determined by
the quality of the recovery mechanics.
Ground Preparation
Ground preparation is the second most important phase in the running cycle.
There is a very high correlation with parameters associated with ground
preparation and achieving optimal performance in high-speed running and
maintaining a greater percentage of the velocity attained.
Ground preparation begins with the negative acceleration of the thigh. It must
be emphasized that the athlete who achieves high angular velocity values
through mechanical efficiency does not rely on gravity alone to accelerate the
thigh. The high-level sprinter actively engages the gluteals, after experiencing the
stretch shortening action of the transition phase, and other hip extensors to
actively accelerate the thigh to and through the Ground Phase.
Again, moment of inertia must be minimized. This is accomplished by
maintaining total relaxation in the muscles around the knee joint. If the knee is
allowed to be loose and unrestricted, the mass and the length of the lower leg do
not affect the moment of inertia of the thigh. Once the muscles around the knee
contract and stabilize, the limb becomes unitized and the total length and mass
of the leg increases the moment of inertia, thus reducing the capacity to
accelerate of the thigh.
Through this entire thigh acceleration, the ankle remains dorsiflexed in
anticipation of touchdown. By repositioning the foot in dorsiflexion, the athlete
aims to turn the foot and ankle into a springboard, storing elastic energy during
the ground phase.
As the thigh actively accelerates, the lower leg, because of its own inertia,
passively extends at the knees joint. The great American sprint coach Bud Winter
described this as "foreleg reach"'. This concept is frequently misinterpreted to be
an active extension of the knee joint, rather than a result of high rate of
13. acceleration of the thigh in a negative direction with the musculature around the
knee joint relaxed (see Photo 9).
Just before touchdown, at the point of near maximum passive extension of the
knees joint, the athlete elicits a maximum co-contraction of the musculature
around the knee joint, thus stabilising the knee joint and turning the leg into a
unitized "fiberglass vaulting pole" as he/she continues to "grab" the foot under the
body. Because angular velocity around the hip joint has been maximized just
prior to touchdown, unitizing the leg generates a high negative foot speed. This
minimizes breaking forces.
High angular acceleration, which results in high negative foot speed coupled
with the high quality recovery mechanics of the other leg yields a small frontside
distance (the distance between touchdown of the ball of the foot and the centre
of mass). This further minimizes breaking forces.
Ground Phase
The Ground Phase begins at touchdown and has two distinctly different
aspects, the Frontside Phase and the Backside Phase. It is important to note that
the mechanics occurring in these two phases during highspeed running are very
different from the mechanics occurring during the acceleration.
Frontside Phase
14. The aim in the Frontside Phase is to horizontally displace the centre of mass
from touchdown through mid-stance to take-off in as short a time as is possible.
During the Frontside Phase in high-level performers, the thigh continues to
accelerate at the hip joint while the foot is grounded. Further, because of the co-
contraction and stabilization of the knee joint and the small frontside distance,
very small amounts of knee joint amortisation should be seen (see Photos 10
and 11).
This being the case, the athlete must be cued to explode through the track or
tear back the track. This is done by continued engagement of the synergistic
hamstring muscles in concert with the gluteals. Premature deceleration of the
thigh at the hip joint is often due to either a faulty conceptual technical model or
insufficient elastic power of the hamstrings and gluteals. It may also be a result of
insufficient negative foot speed or excessive frontside distance from a low quality
ground preparation phase.
Backside Phase
The Backside Phase begins at mid-stance, when the centre of mass is over
the base of support. The cue for the athlete is to continue to push through the
ground from the hip. Even though this cue is somewhat incorrect from the point
of view of what is happening neuro-biomechanically, it avoids the tendency to
15. prematurely initiate recovery mechanics. This is frequently referred to as rushing
the movement.
Interestingly, and somewhat surprisingly, the more important of the two parts
of the ground phase in high-speed running is the predominately stored elastic
energy. Only 30% of the force is realized in the Backside Phase. When there are
greater breaking forces at touchdown, and concomitantly greater deceleration of
the centre of mass, the athlete must generate greater forces in the Backside
Phase in an attempt to reaccelerate the centre of mass back to the previous
speed at take-off. Deceleration of the sprinter results when this is no longer pos-
sible (such as during the Speed Maintenance Phase of the 100 meters) in order
to have a net change in velocity of zero from touchdown to take-off.
Arm Action
Arm action is like operating a vehicle on a one-way street. You only drive in
one direction. The term "drive" in sprinting is related to the application of force by
extension at a joint. In this case we are speaking about the shoulder joint. The
sprinter positions the hands so the thumbs are up, the palms are facing in and
the wrists are loose. The elbow is positioned at a "loose" 90° angle.
The arm is abruptly accelerated by the shoulder extensors. Imagine that your
hands are two hammers and the nails are in the wall behind you. Now hammer
the nails as rapidly as you can, maintaining the hand position and elbow
alignment. What Kevin McNair calls "Hammering the Hand", requires active
shoulder extension; however, the recovery of the arm into shoulder flexion is
accomplished by the stored elastic energy in the anterior deltoids, pectoralis,
and, most importantly,
A common arm action fault is known as dog paddling. This is when the
movement of the arms resembles the action of the forelegs of a swimming dog. It
results when the forearms are pronated at the radio-ulnar joint. Pronation results
in an inhibition of the biceps brachii and a facilitation of the smaller
bracheoradialis. The biceps is the most important muscle for storing elastic
energy to facilitate arm recovery, so a neutral radio-ulnar joint "turns on" the
biceps.
Conclusion
The coaches of the world's fastest sprinters use the technical model of
maximum velocity sprinting that is discussed in this article. Many times this has
resulted from exposure to the new way of thinking through the coaches education
systems of the Central American & Caribbean Athletics Confederation and the
IAAF followed by empirical implementation of the model. It is clear that
extraordinary results at all levels of sprinter development have been achieved. To
retain the traditional technical model is to limit your sprinters' performance
