The influence of plyometrics training on the maximal power of the lower limbs in basketball players aged 16–18
Journal Title: Antropomotoryka. Journal of Kinesiology and Exercise Sciences - Year 2010, Vol 20, Issue 49
Abstract
[b]Aim of the work. [/b]The study was aimed at assessing the influence of plyometric training on explosive strength development dynamics in running and jumping among basketball players, since basketball is a sport discipline dominated by strength and speed abilities. The combination of these two constitutes explosive strength enables the athletes of various sport disciplines to perform at the highest level of their technical and tactical skills.[b]Material and methods.[/b] Thirty-six basketball players aged 16–18 participated in the study. They were divided into experimental (E) and control (K) group. Running speed (5 m, 15m, 20m and 30m distance), speed endurance (10 × 30 m run), explosive strength of trunk and legs (recorded on a dynamometric platform) as well as strength endurance of leg flexors and extensors in isokinetic conditions were measured at the beginning and at the end of the experiment.[b]Results.[/b] The training regimen did not result in any significant changes in the examined motor abilities of basketball players in the control group. The introduction of plyometric training in the experimental group resulted in a statistically significant strength torque increase in knee flexors and extensors of both joints (measured at 60º/s, 120º/s, and 240º/s angular velocity). Moreover, changes were observed in the conventional ratio of hamstrings and quadriceps muscles of the right extremity. Specific training activities positively influenced the speed endurance assessed with the use of a shuffle run (10 × 30 m). There were no significant differences in the level of running speed and explosive strength of legs.
