Means of strength training in the structure of health training for young men.

The construction of health training based on strength-oriented classes in combination with the diet and means of recovery has a positive effect on the state of health and physical devel-opment of a young organism. This type of training makes it possible to achieve and maintain a high level of strength and endurance for many years, reducing the impact of negative environmental factors. The pur-pose of the work is to determine the effect of strength training on the functional capabilities, level of physical condition, and health of young men. Research methods – theoretical analysis and generalization of sci-entific and methodological literature according to PRISMA 2020 recom-mendations for systematic reviews and meta-analyses. Inclusion crite-ria for studies were developed based on the PICOS model (population, intervention, comparison, outcome, study design). The study included publications that analyzed functional and physiological changes in healthy men aged 18-44 years under the influence of strength training of various intensities. The results. 13 publications matching the search criteria were found, from which 9 studies were selected after exclud-ing irrelevant ones. Most articles were rated as good-quality studies with a score of 7-9 on the PEDro scale. Long-term strength training has been found to significantly improve strength, muscle mass, and explo-siveness in trained individuals. Strength training 3 times a week can in-crease lean body mass and left ventricular mass index, with a decrease in fat mass. Three 13-minute strength training sessions per week lead to increased muscle strength compared to longer, moderate-intensity workouts. Light training stimulates hypertrophy of the soleus muscle more than heavy training, which affects the middle and lateral heads of the calf muscle more. The sequence of exercises does not affect the increase in maximal strength, but the effect on pectoral muscle hyper-trophy may be better when multi-joint exercises are performed after isolated ones. The appearance of microRNAs does not show specificity in the early acute state of training, changes in expression are observed 8 hours after training. The duration of weight-lifting training has a posi-tive effect on anthropometric and physiological indicators. Conclusions.A systematic search revealed 9 relevant publications. Most studies showed high methodological quality (7-9 points on the PEDro scale). The review showed that different strength training regimens have a positive effect on physical and physiological performance in healthy young men. In particular, regular strength training significantly improves 1-RM, lean body mass, and morphological and functional parameters of the heart
