Acute Effects of a 30 s Maximal Anaerobic Cycling Test on Change-of-Direction Performance During Recovery.

Area of Science:

• Sports Science
• Exercise Physiology
• Biomechanics

Background:

• Change-of-direction (COD) performance is crucial in many sports.
• Maximal anaerobic exercise can induce fatigue, potentially impacting COD.
• Understanding recovery kinetics post-anaerobic exertion is vital for training.

Purpose of the Study:

• To investigate the acute effects of a 30-second maximal anaerobic cycling test on COD performance.
• To determine if these effects differ between genders and experimental/control groups.
• To assess COD performance recovery over a 10-minute period.

Main Methods:

• 64 university athletes (33 males, 31 females) participated.
• Participants were assigned to experimental or control groups.
• Illinois test assessed COD performance at baseline and 4, 6, 8, 10 minutes post-test using photocell timing.

Main Results:

• Significant main effects for Time, Group, and Sex were found (p < 0.05).
• COD performance showed time-dependent changes, with group and sex differences observed.
• No significant interactions indicated similar recovery patterns across groups and sexes.

Conclusions:

• A 30-second maximal anaerobic cycling test acutely impairs COD performance.
• Full recovery of Illinois test performance was not achieved within 10 minutes.
• Recovery patterns for COD performance were consistent across genders and groups.
