title: [Effects of different types of training on torque/angular velocity relationship. Experimental study by isokinetic ergometry in high-level basketball players].
abstract: The purpose of this study was to examine the alterations of the Torque/Angular Velocity relationship in knee extensor and flexor muscles due to a long-term training programme. Thirty five young elite basketball players were tested before, after 12 weeks of a common weight-lifting programme (including concentric and eccentric actions) and after 24 weeks including only concentric (C-E/C group) or concentric and eccentric actions (C-E/C-E group). After 12 weeks, significant decrease in torque of knee extensor muscles was observed. In contrast, significant increases in torque of knee flexor and shoulder flexor and extensor muscles were noted. After 24 weeks, significant increases were noted in torque of all muscular groups, for the C-E/C group but not for the C-E/C-E group. It is concluded that training including concentric and eccentric actions have not the same effect on agonist and antagonist muscular groups. The alternation of the contraction mode influences straingthly the strength restoration.
