Stretching and strength exercises in relation to running speed and anaerobic power in basketball players
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2012, Vol 22, Issue 57
Abstract
[b]Aim of the study[/b]. This study aimed to identify the effect of stretching and strength exercises on running speed and anaerobic power of young (13–15 years old) basketball players, and the relationships between variables representing their speed, anaerobic power and flexibility. [b]Material and methods[/b]. Thirty-six young basketball players were randomly allocated to 3 groups (GR, GS and GC) that carried out special 3-month training programs. Before the training macrocycle commenced and after it ended, the participants were tested for running speed, anaerobic power and flexibility.[b]Results[/b]. ANOVA and post hoc test showed that the “training factor” distinguished more clearly the strength exercise subgroup and the stretching exercise subgroup (p = 0.002 and p = 0.003, respectively). The discriminant analysis showed that power, 5-meter running speed and 20-meter running speed were these variables that distinguished the strength exercise subgroup. In addition, the results of post hoc tests, pointed the level of flexibility as a factor which discriminated more clearly subgroups GR and GS, and then GS and GC (p = 0.005, p = 0.009 and p = 0.006, p = 0.012, respectively).[b]Conclusions[/b]. The experiment has demonstrated that under the absence of strong stretching stimuli even low-volume strength exercises lead to the dynamic development of anaerobic power, running speed and flexibility, whereas more intensive stretching exercises limit improvements in these motor abilities.
