Integral method of quantitative estimation of load capacity in power fitness depending on the conditions of muscular activity and level of training

The paper presents the results of study dedicated to the search for effective methods of quantitative evaluation of power loads that allow developing and introducing into the fitness training process safer and simultaneously more effective modes of muscular activity for achieving maximum adaptive reactions in the body of people with different levels of training and functional abilities. To conduct the research we formed a group of 40 trained males aged 20-21 engaged in power fitness for the last three years. The obtained results show that changing at least one index that influence on the conditions of muscular activity in fitness significantly affects not only the choice of the projectile working mass, but also the entire load regime orientation and the training process on the whole. It was found out that while performing partial amplitude exercises (90% of the total), despite the projectile working mass that the athlete can lift will be 5-7% more from the full amplitude of motion mass, which is more characteristic of classical power sports (weightlifting, power lifting). It should be noted that other load regime indicators are identical with the conventional ones. At the same time, when performing a partial amplitude training exercises, the number of repetitions in the set decreases because of appearing the premature muscle fatigue and lack of a fixation phase at the peak point during boom lifting. An empirically developed integral method for estimating the load in power fitness is one of the most important methodological elements necessary to optimize the training activities management process. The use of this method allowed us to clearly define the volumes of exercise used in power fitness in the appropriate quantitative units. Thanks to the development of this method of assessing the power loads, it became possible to avoid sufficiently subjective gradations (small, medium, large) that were previously used by researchers and practitioners in the field of sports physiology, sports theory and practice, and sports medicine. The quantitative values of the indicators provided an opportunity to control the design of the training process in details, depending on the load regime characteristics and the level of person's physical fitness.
