Reliability and Validity of a Flume-Based Maximal Oxygen Uptake Swimming Test

Area of Science:

• Exercise Physiology
• Sports Science
• Performance Analytics

Background:

• Accurate assessment of maximal aerobic uptake (VO2max) is crucial for evaluating swimming performance.
• Existing protocols may not be suitable for flume environments, necessitating reliable and valid methods.
• A standardized flume protocol is needed to assess VO2max in swimming.

Purpose of the Study:

• To evaluate the test-retest reliability of a novel VO2max swimming flume protocol.
• To determine the performance validity of the flume protocol against a criterion 457-m pool swim test.
• To establish the flume protocol as a viable alternative for assessing swimming-specific VO2max.

Main Methods:

• Nineteen participants (9 males, 10 females) completed two VO2max flume tests (A and B) and one 457-m pool performance swim (PS).
• Measurements included VO2max, O2pulse, maximal ventilation (VEmax), test duration, and post-exercise blood lactate (BLa).
• Statistical analyses assessed test-retest reliability (Trials A vs. B) and performance validity against the PS test.

Main Results:

• The flume protocol demonstrated moderate to strong test-retest reliability for VO2max (r=0.628), O2pulse (r=0.502), VEmax (r=0.671), test time (r=0.608), and BLa (r=0.716).
• Performance validity was supported by moderate to strong correlations between flume VO2max (r=-0.648), O2pulse (r=-0.623), VEmax (r=-0.509) and 457-m swim times.
• All relationships were statistically significant (p < 0.05).

Conclusions:

• The swimming flume protocol is a reliable and valid method for assessing VO2max in swimmers.
• This protocol provides a valuable alternative for military personnel, open water swimmers, and athletes seeking to enhance swimming performance.
• The findings support the use of flume-based testing for mode-specific aerobic capacity evaluation in swimming.
