Resumen:
Introduction: High soluble-fraction levels of Alpha-Klotho have been related with anti-inflammatory effects on the organism, decreased degenerative processes, and longevity[1-2]. In addition, SαKl levels increase immediately after an acute endurance exercise that does not occur after plyometric exercise[3]. Nevertheless, there is no literature to date regarding the behavior of the protein during the recovery period following plyometric exercise. Due to its well-known antiinflammatory response, we hypothesized that a SαKl levels increment could happen during the hours following a plyometric exercise session. Our main objective was to analyze the acute effect of a single plyometric exercise bout on SαKl and its kinetics during the 72 following hours. Method: 39 physically-active males (aged=18-35; VO2max=55.6±5.19 ml/kg/min) underwent one eccentric-focused plyometric session. Their serum SαKL and Creatine-Phosphokinase (CPK) levels were measured before (PRE) and immediately after (POST) the session, as well as 24, 48 and 72 hours later. Results: We found overall significant differences in the SαKl kinetics (F=4.182; p=0.011). SαKl increased significantly between POST and 24h (p=0.041; d=0.499) and ...
