Swim drink study: a randomised controlled trial of during-exercise rehydration and swimming performance.

ABSTRACT:

Objective

To determine whether during-exercise rehydration improves swimming performance and whether sports drink or water have differential effects on performance.

Design

Randomised controlled multiple crossover trial.

Setting

A UK competitive swimming club.

Subjects

19 club-level competitive swimmers, median age (range) 13 (11-17) years.

Interventions

Subjects were scheduled to drink ad libitum commercial isotonic sports drink (3.9 g sugars and 0.13 g salt per 100 mL) or water (three sessions each) or no drink (six sessions) in the course of twelve 75 min training sessions, each of which was followed by a 30 min test set of ten 100 m maximum-effort freestyle sprints each starting at 3 min intervals.

Main outcome measure

Times for the middle 50 m
