The aim was to evaluate torso muscle physical capacity, functional movement patters and to analyze the correlations between these components. In general, one-segment evaluations are carried out: a range of motion, physical fitness, one muscle group endurance evaluation. There is no observable correlation between the results of number of fitness components, which is compounded by personal physical fitness level and comprehensive quality of motion assessment. We evaluated a comprehensive approach to the human body, its physical capacity and functional movements. Lithuanian and foreign authors in recent years mostly research health of the young age adults. These authors agree that the number of people with excellent health decreases very fast, while a variety of health problems increasing. One of the reasons for the worse health is low physical activity. Lifestyle has become sedentary, leisure time spent passively as well, habits and daily activities changed comparing to what it was 15–20 years ago. Poor physical capacity and worse performance of functional movements is one of the reason of the worse health. The study involved 382 people aged 18–24 years (mean age value – 19,11 ± 0.84 years). The study included 264 women and 118 men, the weight of the average value of 66.78 ± 13.04 kg, height – 1.72 ± 0.09 m. One-time testing was carried out. The study consisted of physical fitness components (balance, flexibility, hand speed and torso muscle endurance) and functional movement screen (using FMS system – 7 functional movements). Balance was tested using Flamingo test. The test was carried out for left and right feet. Arm movements speed was evaluated using Teping test, left and right hands. Flexibility was assessed via “Sit and reach” test and using inclinometer, when assessment was in Th12–L1 and L4–L5 segment mobility. Trunk muscle endurance was evaluated with the following tests: Kraus-Weber test – the upper part of the abdominal muscle endurance assessment and ITO test – back extensor muscle endurance assessment. We also evaluated lateral trunk muscles (left and right side) endurance. Evaluation of functional movements was made with the following tests: deep squats, hurdle step, in-line lunge, shoulder mobility, active straight leg raise, trunk stability push-ups, rotary stability. The quality of motion was assessed by G. Cook criteria and evaluated on a scale from 0 to 3. The study found that there is a weak to moderate correlation (direct and reverse) between physical fitness components and functional movements. The results of the study showed that functional movements and torso muscle exercise capacity significantly related to each another; in case of low torso muscle exercise capacity it will result in: disturbed, unstable performed functional movements. From the research results we conclude that the stability of the trunk is important, when people take movements of legs in open kinetic chains while standing on one leg, lying on the back or on position four (arms and legs). Trunk stability is important also when people take movements in closed kinetic chain – standing on two legs and the squats. Fast hand movements depend on the performance of the trunk muscle endurance. As a result, we observed that the better performance of functional movements that require good trunk muscles stability and large muscle endurance, the more quickly people perform the task, which requires good coordination of arm movements. Trunk muscle functional capacity ensure the correct and stably performance of functional movements. Keywords: young age, functional movement screen, physical capacity.
