STATIC STRENGTH ENDURANCE OF TRUNK MUSCLES AS A FACTOR OF PHYSICAL PERFORMANCE IN FEMALE STUDENTS

Abstract

Aim. The paper aims to identify baseline levels of static strength endurance of trunk flexors and extensors that play a significant role in providing high levels of physical performance during aerobics. Materials and methods. The study involved 1^st–4^th year female university students (Derzhavin Tambov State University) who chose aerobics as physical education electives. Static strength endurance of trunk flexors was evaluated by the time of the 45-degree leg raise and hold exercise; static strength endurance of trunk extensors was evaluated by the time of the prone arm and leg lift exercise. Results. There were signi­ficant differences in static strength endurance of trunk flexors and extensors between 1^st to 4^th year female university students (P < 0.05). The time of the 45-degree leg raise and hold exercise was 37.4 ± 19.3 s, 59.2 ± 17.2 s, 44.88 ± 26.9 s, and 40.19 ± 18.9 in female university students of 1^st to 4^th year, respectively. The time of the prone arm and leg lift exercise was 71.1 ± 23.2 s, 96.04 ± 29.9 s, 82.45 ± 27.11 s, and 80.37 ± 26.9 s in female university students of 1^st to 4^th year, respectively. Conclusion. The data obtained allowed for the identification of trends in the development of strength abilities in female university students and served as the basis for the development of a scale for measuring static strength endurance.
