title: Years of training and hamstring-quadriceps ratio of soccer players.
abstract: To investigate the effect of the years of training on the hamstring-quadriceps isokinetic strength and establish normative data for the cardiorespiratory fitness of first and second division Greek male professional soccer players (M=25.1, SD=5.1 yr.) a representative sample of 72 soccer players was chosen randomly from six teams of these divisions. Hamstring-quadriceps ratios of the preferred and nonpreferred leg correlated with years of training weekly (r = .51) in the preferred leg. In conclusion, data indicated that the training background of the players (years of training) might have a small effect on the strength balance of quadriceps and hamstrings of the preferred leg.
