Dynamics of indicators of active and passive flexibility during the annual cycle of stretching classes

Abstract

Purpose: this study analyses the dynamics of indicators of active and passive flexibility in the joints of the upper extremities in girls aged 15-16 years after an annual cycle of extracurricular stretching classes. Design/methodology/approach: during the school year, 35 high school girls were involved in extracurricular stretching classes three times a week. Classes lasted for 90 minutes and had a traditional structure: preparatory, main and final parts. We investigated the effect of stretching exercises on active and passive flexibility in the joints of the upper extremities using the goniometry method. Findings: goniometric measurements after a oneyear cycle of stretching classes proved the effectiveness of the implemented extracurricular program. Having a systematic training throughout the year, girls aged 15-16 years improved flexibility in the joints of the upper extremities, statistically significantly increased the movement amplitude in the joints of the upper extremities. It can be argued that specially organized motor activity in the form of stretching classes changes the mobility indicators of the joints of the upper extremities. Such changes are an indicator of preventive measures against domestic injuries. Research and practical limitations/implications: the results of our study confirm the effectiveness of implementing extracurricular stretching classes in secondary schools. It should be also stated the limitation includes a relatively small sample size for statistical measurement, but it does not significantly affect the results of the study. Originality/value: lots of scientists study the role of stretching classes mainly in a sports environment, however, we investigated the health-improving effect of using stretching classes to increase motor activity and improve the quality of life of high school girls, but not athletes.
