Hydro electrolytic responses after a training session in some Cameroonian soccer players

Abstract

Playing soccer in hot climates can lead to significant fluid and electrolyte losses, resulting in higher levels of dehydration. The aim of this study was to quantify the fluid and electrolyte sweat losses among selected Cameroonian soccer players during a training session. Thirty soccer players aged 22 ± 5 from two teams (RENAIS and JACY) playing in the first division participated in a specific training session lasting about 1 hour 30 minutes. Before and after the session, all players were weighed. Sweat samples were collected to determine the sodium concentration. Ten participants completed a questionnaire providing information on their dietary and fluid intake, sweating habits, and salt intake routines. We found that JACY players had a significantly higher average sweat rate (1.73 ± 0.45L/h) compared to RENAIS soccer players (p = .038). A positive correlation (r = 0.47; p = .023) was observed between body mass index and sweat rate. A percentage of 33.3% of players presented the “salty sweater” profile. A dehydration level of 3.3% was found. 30% of players admitted to experiencing frequent cramping. The results indicate that Cameroonian soccer players experience significant fluid and sodium losses and are not adequately hydrated during training sessions.
