Effects of Reduced Training on Muscular Power in Swimmers

Area of Science:

• Sports Science
• Exercise Physiology
• Swimming Performance

Background:

• Athletic training often involves periods of reduced intensity and volume, known as tapering.
• The physiological effects of tapering on power output and performance in swimmers require further investigation.

Purpose of the Study:

• To investigate the impact of a 14-day tapering period on maximal arm power and performance in male collegiate swimmers.
• To assess changes in acid-base balance following reduced training in elite swimmers.

Main Methods:

• Seventeen male collegiate swimmers participated in the study.
• Maximal arm power was measured using a biokinetic swim bench and a tethered swim test.
• Swimmers completed a 200-yard swim at 90% of their season's best velocity before, during, and after tapering.

Main Results:

• A significant increase (p <.05) in power output was observed on both the biokinetic swim bench and the power swim test after tapering.
• Swimmers' performance times improved by an average of 3.1%.
• Tapering did not significantly influence postexercise acid-base balance.

Conclusions:

• A 14-day tapering period effectively enhances muscular power and improves swimming performance in collegiate athletes.
• The observed performance gains are likely attributable to increased muscular power.
• Tapering does not appear to negatively affect acid-base balance in this population.
