Evaluation of two muscle training programs by assessment of the muscle tone

Muscle parameters like muscle tone and elasticity are important for development of the training program in relationship with speed reaction and to maintain the body position. We propose to make a comparative study between two types of muscle training using myotonometry to estimate the muscle tone. We make a comparison between two types of muscle training for two athletes (age –18 years) that participate at two different muscle training programs. The assessment of muscle parameters included: muscle tone (frequency F), elasticity (decrement), stiffness and index force, by myotonometry for rectus femoris (RF) and tibialis anterior (TA). The training program: develop the execution speed by increasing explosive strength-training program T1 of the lower limbs versus the training program which aims to develop the maxim force by isometric exercises T2. We observe that for RF, F has a symmetry right/left for T1 and very close to norms, but at the same time for T2 we observe a high difference between right/left side, and high value for RF left side, that means an overuse of muscle group and an important decrease of the RF right side, that means muscle fatigue. The results of muscle tone assessment by myotonometry can be an indicator for fatigue. The training program based on plyometry, stretching and development of speed, improve the muscle parameters and reduce the risk of muscle fatigue and muscle injury. At the same time the T2 training program, based on isometric contraction and static strength training, increase the asymmetry between right and left side and also decrease the elasticity. Paramètres musculaires comme le tonus musculaire et l’élasticité sont importants pour le développement du programme de formation en relation avec la réaction de vitesse et pour maintenir la position du corps. Nous proposons de faire une étude comparative entre les deux types de préparation/entraînement de muscle en utilisant myotonométrie pour estimation des méthodes de tonus musculaire. Nous faisons une comparaison entre les deux types de formation de muscle de deux athlètes (âge : 18 années) qui participent à deux différents programme de formation de muscles. L’évaluation des paramètres musculaires inclut : tonus musculaire (fréquence de F), l’élasticité (décrémentation), la rigidité et la force de l’index, par myotonométrie pour rectus femoris (RF) et tibial antérieur (TA). Le programme de formation : développer la vitesse d’exécution en augmentant de façon explosive le progr
