Abstract

This study aims at assessing the changes in renal parameters induced by the 30-15 Intermittent Fitness Test (IFT) in female handball players of the Republic of Benin. The study sample was categorised as experimental (EG: n = 7) and control (CG: n = 6) groups. Glomerular filtration rate (eGFR) with two formulas, urine specific gravity (USG), fractional sodium excretion (FeNa), urinary sodium-potassium ratio (Na/K) and plasma volume variation (PV) were determined before, just at cessation and three hours after the test. In the end, eGFR and PV decreased by at least 17.2% (p < 0.05) according to the formula and 9.2% in the EG group while in CG, FeNa and PV increased, respectively by 39% (p = 0.017) and 1.7%. Three hours after the test, eGFR and PV increased by 10.5% (p = 0.02) and 1.4%, while FeNa decreased by 25% (p = 0.02) in EG. In CG, FeNa decreased by 12.5% and PV increased by 2.7%. Urinary Na/K ratio remained unchanged (p > 0.05) in both groups. The 30-15 IFT induced in hot environment, a transient reduction of eGFR and a decrease of FeNa during recovery in female handball players.
