Strength Simulator Codes for Different Age Groups Considering Physiological Processes of Adaptation in Conditions of Strength Fitness

Topicality. Determination of optimal load parameters in fitness, based on age-related physiological features and adaptive changes of the neuromuscular system, is one of the most debated issues among leading scientists in this field. The research purpose was to develop models of code combinations for strength training of different age groups, considering physiological processes of human body adaptation to a stressful physical stimulus in the conditions of strength fitness. Methods. A comparative analysis of the research results on the effectiveness of using the optimal combination between the parameters of an external physical stimulus and the physiological features of the human body adaptive reactions has been used over the research. The results. It was established that in the process of developing code combinations for different age groups` strength training, the nature of the physiological reactions of their neuromuscular system to a stressful stimulus depend on the features of the load regime and the structure of the exercise program. For adolescence, considering the peculiarities of the physiological process of adaptation, it is used of moderate-intensity activity in combination with a complex of isolation exercises that promotes the processes of intra-muscular and inter-muscular coordination. For youth, in the process of developing code combinations aimed at the development of the main types of strength, the entire range of load modes is actively used. Particular attention is paid to stimuli that contribute to increasing the number of active (FF) motor units. In adulthood, especially in the second period, the content of code combinations to increase strength capabilities changes significantly. In the vast majority, this applies to the parameters of the intensity of load modes, the use of which will selectively affect the hypertrophy of a certain type of muscle fibers within intermuscular coordination. For the elderly, in the process of developing code combinations for strength training, priority is given to the selective activity of agonists during moderate-intensity isolated exercises. Findings. Strength Simulator codes considering physiological processes of the neuromuscular system adaptation to a stressful physical stimulus, is one of the innovative mechanisms for improving the training program of different age groups in the conditions of strength fitness.
