Application of suspension training systems in swimmer preparation during the stage of sports mastery improvement

The purpose of the study is to substantiate the effectiveness of using TRX straps in the speed-strength training of swimmers aged 12-14 at the stage of improving sports mastery. Research methods and organization. The following methods were applied: analysis of scientific and methodological literature, pedagogical experiment, testing, anthropometric measurements, and methods of mathematical statistics. The study was conducted at the 'Youth of Moscow' Specialized Children and Youth Sports School of Olympic Reserve 'Trud' in swimming, with the participation of swimmers of Candidate for Master of Sport (CMS) qualification. The duration of the experiment was 12 weeks. In the experimental group, 90-minute sessions using the TRX Suspension Trainer were conducted twice a week; the program included 23 exercises aimed at developing the muscles of the upper shoulder girdle, lower limbs, and core. Research results and conclusions. It has been shown that the use of TRX straps contributed to a more pronounced improvement in strength performance in athletes of the experimental group. Significant differences were found in hand pull strength in water, pull strength with full movement coordination, as well as in the "sit-up from a supine position" test.
