Optimizing active recovery strategies for finger flexor fatigue

Area of Science:

• Exercise Physiology
• Sports Science
• Human Performance

Background:

• Active recovery (AR) is employed during training to enhance performance.
• Optimal AR strategies for localized upper body performance remain unclear.
• This study investigates AR's impact on repeated finger flexor performance.

Purpose of the Study:

• To compare the effectiveness of different active recovery strategies on localized upper body performance.
• To determine if whole-body, upper extremity, or lower extremity active recovery best maintains finger flexor strength.
• To provide evidence-based recommendations for AR protocols.

Main Methods:

• A crossover trial design was used with three laboratory visits.
• Participants completed three exhaustive intermittent isometric tests of finger flexors at 60% maximal voluntary contraction.
• Active recovery interventions included walking, intermittent hanging, and climbing for 22 minutes between tests.

Main Results:

• All AR strategies led to a significant decrease in impulse from the first to the third trial.
• Walking as AR resulted in a significantly higher impulse in the third trial compared to climbing and hanging.
• Performance decline was most pronounced after climbing and hanging interventions.

Conclusions:

• Walking is a superior active recovery strategy for maintaining repeated intermittent finger flexor performance compared to climbing or hanging.
• Active recovery involving the same muscle groups (forearm) should be avoided between exhaustive contractions.
• These findings suggest that whole-body active recovery may be more beneficial for localized performance maintenance.
