Eccentric-concentric Ratio: A Key Factor for Defining Strength Training in Soccer
The aims of this study were to analyse the effect of chronic strength training over concentric power (CON), eccentric power (ECC), ECC/CON ratio, and 20 m linear sprint performance in elite young soccer players.

| Sumario: | The aims of this study were to analyse the effect of chronic strength training over concentric power (CON), eccentric power (ECC), ECC/CON ratio, and 20 m linear sprint performance in elite young soccer players. Twenty young elite Spanish soccer players were assigned to an experimental group (CPG) which performed a front-step exercise using a conical pulley, 2–3 sets of 6 repetitions each leg, during 9 weeks (CPG, n = 10) in addition to its usual strength training, or to a control group (CG, n = 10). The improvements in the ECC mean power (36 %, ES = 1.61), and ECC / CON ratio (17 %, ES = 1.77) were substantially greater in the CPG than in the CG while the CON mean power (16 %, ES = 0.83) was substantially greater in the CG than in the CPG. The sprinting time for 10 m (2.8 %, ES = 0.78) and the 10 m flying time between 10–20 m (1.72 %, ES = 0.41) were substantially enhanced in CPG and CG respectively. To be efficient when defining a functional strength training and performance increments using an inertial device, the mean power output need to be measured during the CON and ECC phases and an analysis of the ECC / CON ratio should be included. |
