측정시기에 따른 복합운동이 청소년들의 근력과 유연성에 미치는 효과 연구

다국어 초록 (Multilingual Abstract)

The aim of this study was to examine effects of 6-months-long combined exercise on adolescent’s strength and flexibility.
Twenty-two experimental groups (13-16 yrs) and 22 control groups (13-16 yrs) without musculoskeletal disorder participated in the study. Participant’s flexibility and waist and knee strength were measured by sit-and-reach measurement and Micro current measurement system (Biodex in USA), respectively. Experimental group exercised 90 minutes every day, three times a week for 24 weeks. They had 3 minutes of break time between each exercise. Subject’s flexibility and strength were reexamined after 24-week-long combined exercise with identical measurements.
Control group’s general flexibility together with knee and waist flexibility were enhanced. Improvement of knee and waist strength were observed after performing at least 2 months of training. In terms of knee and waist flexibility, at least five months of training showed enhancement.
Combined exercise brings about better outcome than single training for adolescents. Thus, it is recommended to perform over 2 months for strength training and 5 months for flexibility training, in order to see improvements.
