Physiological parameters related to running performance in college trackmen

Area of Science:

• Exercise Physiology
• Sports Science
• Biomechanics

Background:

• Physiological determinants of running performance are crucial for training optimization.
• Maximal oxygen consumption (VO2 max) and submaximal heart rate (HR) are key indicators of aerobic fitness.
• Understanding the relationship between these parameters and performance across different running distances is essential.

Purpose of the Study:

• To investigate the correlation between submaximal and maximal oxygen consumption (VO2) and heart rate (HR) with running performance.
• To compare the effectiveness of walking versus running tests in assessing aerobic power in trained runners.
• To determine the influence of body weight on running performance across various distances.

Main Methods:

• Two studies were conducted on college track team members (n=11 and n=9).
• Study 1 utilized a multi-stage walking test to determine VO2 and HR.
• Study 2 employed a running test for VO2 and HR assessment, and analyzed body weight's impact on performance.

Main Results:

• Max VO2 significantly correlated with 1-mile run performance, while submaximal HR correlated with 1- and 2-mile run performance.
• Running tests yielded higher mean max VO2 than walking tests, suggesting greater validity for trained runners.
• Body weight showed a positive correlation with 100-yard dash performance and a negative correlation with 2-mile run performance.

Conclusions:

• Submaximal HR and body weight are significant predictors of distance running performance, particularly for 1- and 2-mile runs.
• Maximal oxygen consumption is a relevant predictor for middle-distance events.
• Submaximal VO2 did not show a significant relationship with running performance in this study.
