Nordic walking is a form of physical activity that involves walking with specially designed poles to actively engage the upper body. It originated in Finland in the 1930s as a way for cross-country skiers to train in the summer. Nordic walking provides a full body workout that improves cardiovascular endurance, muscular endurance, balance, flexibility, agility, coordination, and prevents injuries. Regular practice of Nordic walking can lead to overall improved physical and mental well-being.

As a runner, it’s important that you do more than simply run. If you want your sessions to be long, fast, and strong, it’s vital to support your body’s capacity to consistently do this. Here’s why strength training for runners is so essential, plus some simple exercises you can try at home, in the park, or at the gym.
In order to make exercise program design more effective, “fitness” can be broken down into various components to help better understand how the body works and how we can use exercise to improve our overall health and performance. Depending on what a person would like to accomplish, these components have been divided into “health-related” and “skill-related” components.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

2. WHAT IS NORDIC WALKING?
• Nordic Walking is a form of physical activity, where to regular natural
walking there has been added the active use of a pair of specially
designed Nordic Walking poles. However, the characteristics of natural,
biomechanically correct walking and appropriate posture are maintained
in all aspects. It also means that the arm movements of the correct
Nordic Walking technique respect the range of movement of natural
walking.
3. • Technically correct use of poles actively involves the upper body into the
work of walking, to propel the body forward. The physical strain is
distributed in a versatile, balanced and appropriate way to various
muscle groups of the whole body.
• The correct pole technique gives an opportunity to significantly intensify
the process of walking by increasing the muscle work of the upper body.
It also gives an opportunity to involve the muscles of the rest of the
body. Nordic Walking is a safe, natural, dynamic, efficient and suitable-
for-all form of a physical activity that trains the body in a holistic,
symmetric and balanced way. The overall goal of Nordic Walking is a
general physical and mental well-being (INWA, 2010).
4.
5. ORIGINS AND DEVELOPMENT
• The fist type of Nordic Walking dates back to the thirties, in Finland, when the national cross
country skiing team started training the skiing technique during the summer, walking and
running with poles. Since then this has been an important off-season training method for every
cross country skier in the world.
• The first research about its health benefits date back to 1966 in Finland. Nordic Walking in its
present form was initiated in 1996 when three organizations joined efforts in order to develop
it: the Suomen Latu, the Sports Institute of Vierumäki and Exel, a finish manufacturer of
poles. Exel invents the name “Nordic Walking” in 1997 and introduces the first composite
Nordic Walking pole, giving birth to the international expansion of this new sport.
6. EQUIPMENT
• Nordic walking poles are significantly shorter than those recommended
for cross-country skiing. Nordic walking poles come in one-piece, non-
adjustable shaft versions, available in varying lengths, and telescoping
two or three piece twist-locking versions of adjustable length. One piece
poles are generally stronger and lighter, but must be matched to the
user. Telescoping poles are 'one-size fits all', and are more transportable.
7. • Nordic walking poles feature a range of grips and wrist-straps, or rarely,
no wrist-strap at all. The straps eliminate the need to tightly grasp the
grips. As with many trekking poles, Nordic walking poles come with
removable rubber tips for use on hard surfaces and hardened metal tips
for trails, the beach, snow and ice. Most poles are made from
lightweight aluminium, carbon fiber, or composite materials. Special
walking shoes are not required, although there are shoes being marketed
as specifically designed for the sport.
8.
9. TECHNIQUE
• The cadences of the arms, legs and body are, rhythmically speaking, similar to
those used in normal, vigorous, walking. The range of arm movement regulates
the length of the stride. Restricted arm movements will mean a natural restricted
pelvic motion and stride length. The longer the pole thrust, the longer the stride
and more powerful the swing of the pelvis and upper torso.
• The 10 step approach to teaching Nordic Walking is based on three principles:
correct posture, correct walking and correct pole technique. It is based on:
posture, walking, carrying, dragging, planting, pushing, extending, recovering,
leaning and rotating
10. BENEFITS OF NORDIC WALKING
• Using Nordic walking poles requires coordinated movements for balance
and stability, strength and endurance, varied cardiovascular efforts,
agility and visual acuity. Added benefits include injury prevention,
enhanced nervous system reactions to move quickly with precision, and
the ability to learn and accomplish other sport skills in less time. The best
health benefit is having a long, active life! To Nordic walk now is an
investment in your athletic future to stay active into your golden years.
11. CARDIORESPIRATORY STAMINA
• Aerobic and anaerobic conditioning are at the core of the Nordic walking workout. Aerobic exercise
utilizes readily available oxygen, glycogen, and fat stores to sustain movement and pace, most often
at a consistent moderate heart rate, and it is performed for longer durations of time. Aerobic
conditioning is the backbone of your training program, not just because it is inherent in a Nordic
walking experience, rather because it preps your body for more intense anaerobic conditioning later
on. Anaerobic activity requires a quicker source for energy, therefore instead of using fat stores, the
main source of fuel is what is stored in your muscles, and what you ate for breakfast. It takes your
heart rate to a new level of intensity that is often difficult to sustain longer than seconds or minutes.
Because it is a distance exercise, Nordic walking is an endurance activity, working many of the
muscle groups used in running and cross-country skiing. It is an ideal activity for cardiorespiratory
fitness because it can be performed at any intensity. Also, those who wish to burn fat will have no
trouble. Those who wish to compete at a higher level have options for intensive training. Others who
simply wish to build a healthier heart or participate in sports can find the appropriate pace to suit
12. • Anaerobic conditioning takes your aerobic training to the next level. We
think of anaerobic conditioning as advanced cardio training. Advanced
cardiorespiratory activity increases both strength and power. The more
intense your cardiac output is, the less readily oxygen is available to
metabolize the fat that sustains energetic movement. Your body taps into
other stores of quick energy for muscle function, such as what you ate
for breakfast in addition to what you ate the day before that is stored as
glycogen in your muscles. Your muscles cannot sustain the intense
demands of this advanced cardio training for long. Instead, you should
use interval training to progressively build your cardio machine.
13. • Benefits of anaerobic conditioning or advanced cardio training include the
following:
1. Healthier heart
2. Greater cardiorespiratory endurance
3. Increased fitness levels
4. Enhanced nerve response
5. Better dynamic balance
6. Faster recovery time
7. Greater speed
8. Improved performance in sports
14. MUSCULAR ENDURANCE
• Muscular endurance is the ability to sustain movement or activity for a
prolonged amount of time. With practice, skilled Nordic walkers acquire a
more athletic gait that combines simultaneous physical reactions with a
faster pace and speed. At this level of training, distance events become
appealing and attainable. Muscular endurance allows you to settle into a
comfortable yet productive pace.
15. BALANCE
• Balance comes from bodily responses that maintain equilibrium. It is just as
beneficial for mobility and body awareness as cardiovascular, strength, and
flexibility. Everyone is born with balance, but savvy athletes know how to train to
cultivate it. Some prefer a less strenuous approach to stability training, such as
with the single-side balance exercise described in chapter 5. However, Nordic
walking challenges you to achieve more dynamic balance because you are
working the upper body to move forward while recovering small imbalances in
the feet, ankles, legs, and pelvis. Poles challenge the upper and lower body
simultaneously, resulting in better balance. Training for balance and becoming
aware of the body’s balance centers will help you attain superior motor efficiency
and athletic ability. Remember that stability, mobility, and balance dance
together at any intensity.
16. RANGE OF MOTION
• Traditionally, power walkers use a shorter stride and an arm swing that
often barely involves the upper body. These movements require less
effort and use fewer muscles. Nordic walking techniques elicit a greater
range of movement and a longer stride that activates more muscles and
propels the body forward with strength. The pole action is an
enhancement of the opposing arm swing used when walking normally.
The increased range of motion allows you to literally cover more ground.
Likewise, flexibility and other fitness qualities improve.
17. AGILITY
• Agility relates to quickness and maneuverability. Starting or stopping suddenly,
pivoting, dodging, jumping, and other types of fast footwork are skills that
require muscle control. A variety of fun agility drills relate to Nordic walking.
Some involve the creative use of poles; others utilize the natural environment.
Agility and balance work together to help you effortlessly adjust to stimulus that
acts on your body to throw it off it’s axis. Examples include impulsive direction
changes or when you reach the top of a hill or run into a headwind. The body
reacts to deflection to stabilize itself naturally. These athletic components are the
prerequisites for coordination.
18. COORDINATION
• Coordination involves a complimentary relationship of movements--a smooth flow
from one slight movement to the next to accomplish an efficient stride. You must
move the upper and lower body both independently and in opposition. Rhythm and
coordination determine pace, which can eventually equal speed. Although power may
not always be required for Nordic walking, coordination is the most obvious athletic
component. Your Nordic walking skills will be efficient when your movements are so
subtle and well memorized that your brain is able to communicate instructions for
movement with ease, developing physical and mental sequential reactions without
wasting energy. Coordination training combines balance, agility, and visual skills. It
can also include power training. Other activities like group exercise classes, sports,
and eye-foot or eye-hand drills are also effective for developing coordination.
19. EFFICIENCY OF MOVEMENT
• Nordic walkers often comment that their practice helps them walk with
greater grace and ease, even without poles. Nordic walking enhances
both posture and coordination. Nordic walking poles lengthen the body’s
levers (the arms and legs as they swing in opposition) and its stride
length (the distance between the feet). Efficiency of movement, or using
as little energy as possible to accomplish skills, is both the result and
objective of skilled Nordic walkers. Additional benefits include fewer
injuries, better reaction time, quicker and more precise movement, and
greater mastery of sport skills.
20. VISUAL SKILLS
• Balance and its recovery depend on visual cues. You need superior visual skills to hit
a baseball, kick a soccer ball, and stay upright when your lightweight poles
accidentally tangle in your legs during a high cross wind! Nordic walkers are
fortunate because the stability created by the pole tips lets them focus their vision
ahead instead of down at the ground. The practice of gazing ahead with a soft focus,
taking in the entire landscape, is much healthier for the spine. If you continually look
down at the ground, the placement of your head can injure your spine, pulling your
shoulders and upper torso away from the center of the pelvis and the axis of
efficiency. Over time, your bones may grow out of alignment. The visual skills gained
during Nordic walking assist postural integrity by helping you appropriately balance
your head’s weight, improving poor posture and eliminating back strain. Adept vision
also helps prevent needless injuries on crowded bike paths and on busy sidewalks.
21. STRENGTH AND POWER
• Training for strength and power develops muscles that are controlled and
responsive. Strength is the prerequisite for intense power training and
injury prevention. Furthermore, it produces positive adaptations that
improve balance, agility, and more. Coordinating simultaneous
movements, like those in Nordic walking, requires full-body effort to
support the demands of repetitive motion and endurance. If performed
safely, a balanced strength program results in muscle balance and back
health.
22. CONCLUSION
• These benefits are achieved through the use of specially designed poles
and a properly learned and performed Nordic Walking technique,
whereby the poles are used as a resistance tool to engage the upper
body. The result is a low impact, high results, total body exercise.
• As a low impact walking exercise, Nordic Walking is something that can
be done and enjoyed individually or as a group activity, anywhere a
person can normally walk. Nordic Walking is perfectly suited to Australia's
climate and can be performed on any terrain -- from sandy beaches, park
trails and grassy fields to urban footpaths.
