2. QUANTITATIVE vs QUALITATIVE
 Quantitative measurement is measurement of data
that can be put into numbers
 Qualitative measurement focuses on collecting
information that is not numerical
Statistical analysis of performance
markers
Movement patterns efficiency

3. QUANTITATIVE vs QUALITATIVE
BAROPODOMETRY/MOTION
ANALYSIS
VIDEOGRAPHY/MOVEMENT
ANALYSIS
STATIC DYNAMIC

4. QUANTITATIVE vs QUALITATIVE
Quantitative analysis involves the measurement of biomechanical variables
and usually requires a computer to do the voluminous numerical calculations
performed.
MOTION ANALYSIS
Numerical values,
objective physics
parameters
Pressure, load distribution,
CoP, force values
development over time

5. QUANTITATIVE vs QUALITATIVE
Quantitative analysis involves the measurement of biomechanical variables
and usually requires a computer to do the voluminous numerical calculations
performed.
MOTION ANALYSIS
HIGHLY OBJECTIVE

6. QUANTITATIVE vs QUALITATIVE
Qualitative analysis has been defined as the «systematic observation and
introspective judgement of the quality of human movement for the purpose
of providing the most appropriate intervention to improve performance»
(Knudson & Morrison, 2002, p. 4)
MOVEMENT ANALYSIS
Movement patterns
efficiency
Ability to move, highly
related to technical
proficiency

(Knudson & Morrison, 2002, p. 4)
MOVEMENT ANALYSIS
HIGHLY SUBJECTIVE

8. QUANTITATIVE vs QUALITATIVE
- Patterns efficiency
- Movement competence
- Technical and neuromuscular
control variables

9. KINETICS vs KINEMATICS
KINETICS
is concerned with determining
the causes of motion
KINEMATICS
is motion description
KINETICS INFORMATION
Knowledge of the
causes of
motion/performance
Identification of the
causes of poor
performance
KINEMATICS INFORMATION
Temporal and spatial
parameters/performance
markers

10. KINETICS vs KINEMATICS
KINETICS
is concerned with determining
the causes of motion
KINEMATICS
is motion description
KINETIC VARIABLES KINEMATIC VARIABLES
Forces between
the feet and the
ground
- Stride length
- Athlete speed
- Angular
velocity of
hip extension

11. SPORTS BAROPODOMETRY
 What is baropodometry?
Technology for the assessment and
measurement of plantar pressures
both in static and dynamic.

12. SPORTS BAROPODOMETRY
 What is baropodometry?
STATIC
Measurement of plantar pressures
during quiet standing.

13. SPORTS BAROPODOMETRY
 What is baropodometry?
DYNAMIC
Measurement of
plantar pressures
during gait (Gait
Analysis)

14. SPORTS BAROPODOMETRY
 What is baropodometry?
 Why sports baropodometry?
State-of-the-art technique for
biomechanical analysis and for the
evaluation of biomechanical function
of foot/ankle complex, hips, lower
extremities, gait and whole body
simmetry and synchrony.
Technology for the assessment and
measurement of plantar pressures
both in static and dynamic.

15. SPORTS BAROPODOMETRY
STEP 1
- Initial screening
- Creation of
baseline and
individual foot
profile
STEP 2
- Daily monitoring
during preparation
- Detection of the effects
of training load on body
neuromechanics
- Adjustments and
intervention (therapy,
recovery, insoles,
correctives)
STEP 3
- Weekly monitoring
during competition
- Detection of the
effects of long-terms
biological adaptations
- Lower kinetic chain
muscle fatigue
