IMPACT OF LOCAL VIBROSTIMULATION ON PARAMETERS OF LEG MUSCLES STRENGTH ENDURANCE

Abstract

Vibration as a tool for massage and rehabilitation has been known for a long time. However, the vibration as a tool in sport workout is used very recently and is being used to increase strength, power, flexibility and coordination. It should also be noted that proper dosing of whole-body vibration plays a very important role in lymph drainage and in the treatment of overloaded joints. Improving and retaining physical fitness as well as repeating sets of exercises on one muscle group to spend as much energy resources in this muscle is important in fitness, in order to increase muscle mass and conditioning. Tonic effect of local vibrostimulation can warm up single muscle or muscle group, but also it can lead to excessive fatigue. So the aim of research is assessment of the effects of local vibrostimulation on the strength endurance for women in seated knee extension motion. Literature was analysed and an experiment was used to find out how strength endurance parameters change for 18-23 year old women after local vibration stimulation. A study was conducted with 20 women aged 18 to 23 years. For these women, control of single leg strength endurance was performed by seated leg extension movement, followed by local vibrostimulation of the quadriceps femoris muscle. This procedure was followed by a repeated strength endurance control. In this study, we found that the strength endurance parameters of the stimulated leg increased by an average of 5 repetitions during 30 seconds of control motion. We conclude that dosed local vibrostimulation sessions can increase strength endurance parameters locally for one muscle group.
