Abstract
Background: The aim of the study was to compare the effect of vibration massage and passive rest on accelerating the process of muscle recovery after short-term intense exercise. Methods: Eighty-four healthy men aged 20 to 25 years participated in the study. Study participants performed isometric (ISO-M Group) and auxotonic (AUX-M group) contraction exercise in the lower limbs. Vibration massage was administered after exercise in the first recovery period. In the same period, controls rested passively, without the support of vibration massage. To assess the effectiveness of the applied vibration, a 4-fold measurement of the maximum force of the muscles involved in the exercise was performed under conditions of isometric contractions on a leg press machine set at an angle of 45° degrees upwards. Results: Differences in maximum strength during isometric contraction were found compared to baseline in favor of the groups subjected to the experimental vibration massage. Differences were demonstrated in muscle strength between the study groups (p < 0.005). The second period of passive rest in all groups did not bring significant changes in the values of maximal lower limb strength. Conclusions: Properly selected characteristics of the vibration effect can be an effective method in accelerating recovery and regaining lost motor capabilities of muscle groups fatigued by exercise. This offers the potential to shorten rest periods between sets of repetitions in training or between training units.
Highlights
Intense physical activity leads to fatigue, resulting in a deterioration of exercise capacity, manifested by a decrease in intensity and efficiency of muscle work [1,2]
The magnitude and nature of the functional changes in the body induced by physical exercise are largely influenced by the intensity, duration, and specificity of the exercise [5]. They are affected by the size and type of muscle groups involved in performing the specific work, the type of contraction of the muscles involved, and the individual body metabolism [6]
The results of our study provide compelling evidence that different frequencies and amplitudes of vibrations may be required, depending on the expected effects of vibration sessions
Summary
Intense physical activity leads to fatigue, resulting in a deterioration of exercise capacity, manifested by a decrease in intensity and efficiency of muscle work [1,2]. The magnitude and nature of the functional changes in the body induced by physical exercise are largely influenced by the intensity, duration, and specificity of the exercise [5]. They are affected by the size and type of muscle groups involved in performing the specific work, the type of contraction of the muscles involved, and the individual body metabolism [6]. During auxotonic and isometric exercise, alternating muscle contraction and relaxation facilitate blood circulation, which supplies the intensely working muscles with oxygen and energy substrates and helps remove metabolic products from them [7,8,9]
