Abstract
Background and Study Aim. There is an increasing interest in using volleyball as a means of physical activity among high school students and a need to assess its impact on speed endurance. The purpose of the study is to identify effective volleyball means for developing speed endurance in high school students in the context of distance and in-person learning.
Material and Methods. The study involved 16 senior high school girls aged 16-18 from Ternovskiy Lyceum No. 1 in Dnipro, Ukraine. The girls performed special exercises over a period of 12 weeks. The weekly schedule included physical education lessons in a format of 1 online lesson/1 offline lesson and 2 additional sessions.
Results. A significant improvement was observed in almost all test exercises: the running time in the "Fir-tree" test decreased by 2.16 seconds (t=3.01, p < 0.05); the running time for 6x6 m decreased by 0.92 seconds (t=3.77, p < 0.05); the number of squats in 20 seconds increased by 4.31 times (t=4.46, p < 0.05); the number of leg raises to a 90° angle in a hanging position increased by 1.13 times (t=3.02, p < 0.05), and the number of torso raises from a lying on the back position increased by 1.81 times (t=4.49, p < 0.05).
Conclusions. The proposed exercises positively affected the development of speed endurance in girls. The obtained results allow recommending these exercises as means for developing speed endurance in physical education classes within the volleyball module.
