The aim of the study is to examine the variation of leg strength and power as well as the flexibility of Greek soccer players four times ( beginning and end of the preparation period , half and end of the competitive period) during the training macro cycle. Twenty four players aged 24.3 ± 4.3 years old participated in the current study. SPSS package (v.17.0) was used for the statistical analysis of the data. The data were analyzed using analysis of variance (ANOVA) at the significance level .05. The results showed that players indicated the lowest knee extensor power before the preparation period . It was also found that vertical jump was significant ly higher in t he end of the competitive period comparing to the beginning of the preparation, the end of the preparation and the half of the competitive period. On the other hand, flexor muscles as well as flexibility did not present any significant difference . The results of this study highlight the need for a systematic strength and leg power training across the annual macrocyle. The muscle imbalances which are created between agonist and antagonist knee muscles may cause injuries, reduction of the neuromuscula r and coordination ability and obstacles on the motor learning process .
