Factors That Contribute to Physical
What the Athlete Gains From
Physiological Testing
• Information regarding strengths and
– Can serve as baseline data to plan training
• Feedback regarding effectiveness of training
• Understanding about the physiology of
Effective Physiological Testing
Relevant to the sport
Valid and reliable
Repeated at regular intervals
Carefully controlled procedures
Interpreted to the coach and athlete
Maximal Run Tests
• Measure how far a person can run in a set time
or how fast they can run a set distance
– Cooper’s 12-minute run and 1.5 mile run
– AAPHERD’s 1-mile run/walk
• VO2max estimates based on the linear
relationship between running speed and
oxygen cost of running
Canadian Home Fitness Test
• Uses 8-inch steps to evaluate cardiorespiratory
• Measure HR after 3 minutes of stepping
– Stop if it exceeds maximum allowable HR based
on age
– Continue for another 3 minutes if it is below
maximum allowable HR
– Fitness level is based on post-exercise HR

Step Test
The Yo-Yo Intermittent Recovery
• The Yo-Yo IR level 1 (Yo-Yo IR1) test focuses on
the capacity to carry out intermittent exercise
leading to a maximal activation of the aerobic
• Yo-Yo IR level 2 (Yo-Yo IR2) determines an
individual’s ability to recover from repeated
exercise with a high contribution from the
anaerobic system
• more sensitive measure of changes in performance
than maximum oxygen uptake
• Widely used, valid, reliable
Protocols for Yo-yo IR1 and IR2

Yo-yo test vs Maximal VO2
Laboratory Tests to Predict Endurance
• Lactate threshold
– Exercise intensity at which blood lactic acid begins to
systematically increase
– Blood samples taken during incremental exercise
• Critical power
– Speed at which running speed/time curve reaches plateau
– An important parameter for aerobic function
• Peak running velocity
– Highest speed that can be maintained for >5 seconds
Test to measure critical power
• Several all-out running/cycling exercise at different
power (W)
– Time consuming, effort consuming
• 3-min all-out cycling exercise
– Subjects need to be highly motivated and fully
familiarized with the test protocol
– During the test, pacing is prevented by absence of any
time-based feedback, and the subject is strongly
encouraged to maximize power output, at all times.
– no decremental trend at any point during the test and
attains >95% VO2max

Tests to Determine Running Economy
• Measurement of the oxygen cost of running at
various speeds
– Greater running economy reflected in lower
oxygen cost
• Higher economy means that less energy is
expended to maintain a given speed
Running Economy
Estimating 10,000m Running Time
Using LT and Running Economy
• VO2 at LT
– 40 ml•kg-1•min-1
• VO2 of 40 ml•kg-1•min-1
– equals running speed of 205 m•min-1
• Estimated 10,000m running time
10,000m  205 m•min-1 = 48.78 min
