Renal Responses to a Series of Handball Games Played in Sub-Saharan Environment by Amateur Division 1 of Female Players.

Abstract

This study aims at assessing the modifications of renal parameters with 13 female players of the same Benin team-amateur Division 1, during two consecutive handball games played 26 hours apart. The players are divided into two groups: starters (ST: N = 7) and nonstarters (NS: N = 6). The estimated glomerular filtration rate (eGFR) with Cockcroft-Gault and MDRD formulas, the fractional excretion of sodium (FeNa), the plasma haemoglobin (Hb) and albumin (Alb) were assayed at rest and at the end of each game. At the end of the first game, only eGFR decreased significantly by at least 16.30% (p < 0.05) in ST only. At the end of the second game, the average reductions of eGFR are significant in both the ST and NS groups (p < 0.05), but they are less important than those recorded at the end of the first (p > 0.05). FeNa varied in no group, neither after the first game, nor after the second (p > 0.05). But a cumulative reduction is observed between the values before the first and those recorded at the end of the second game in both ST and NS groups. The status of the players (ST or NS) did not influence the results. Two games of handball played 26 hours apart in the sub-Saharan environment of Cotonou caused in girls, a transitory decrease in eGFR without a cumulative effect. FeNa decreased too, but with a cumulative effect which indicates large sodium retention.
