A training program for speed-strength tailored to the individual rhythm of young athletes.

Abstract

This study aims to investigate the impact of a training program—aligned with the physical cycle of the biorhythm—on developing explosive strength (speed-strength) among young short-distance swimmers. An experimental approach utilizing a pre-test/post-test design was employed with a single experimental group comprising eight young swimmers, with training sessions conducted twice weekly. The researcher utilized the following tests: arm flexion and extension over 10 seconds, sit-ups from a supine position over 10 seconds, and a maximum-distance forward jump test over 20 seconds. Statistical analysis of the data was performed using the arithmetic mean, standard deviation, and the paired-samples t-test. The results revealed significant differences across all tests, leading the researcher to conclude that the training program was effective. Specifically, structuring intensity levels based on the fluctuations (highs and lows) of the physical biorhythm cycle had a positive impact on developing explosive strength (speed-strength) in young short-distance swimmers. The researcher recommends that coaches consider the physical biorhythm cycle when designing training programs to develop physical attributes and advises against applying the same training program—with identical intensity, volume, and rest periods—to all swimmers, given that their positions within the physical biorhythm cycle differ.
