청소년의 스마트폰 사용 중 간헐적 경부 스트레칭 운동이 근골격계 건강위험요인에 미치는 영향

Abstract

The purpose of this study was to analyze how intermittent stretching exercise affects musculoskeletal health risk factors(neck range of motion, muscle activity, pressure pain) when using the smartphone in adolescents. The results of this study are as follows. First, there was no significant difference in musculoskeletal health risk factors pre and post smartphone use in the experimental group. Second, there were significant differences in musculoskeletal health risk factors pre and post smartphone use of the control group. Third, there was no significant difference in musculoskeletal health risk factors before the use of smartphone in the experimental group and the control group. Fourth, the musculoskeletal health risk factors before the use of smartphone in the experimental group and the control group showed a significant difference in muscle activity of the levator scapula, and no significant difference in other factors. From the above results, it was found that when adolescents use their smartphones for 60 minutes without stretching exercises in a chair sitting position, it was found that the musculoskeletal system (neck range of motion, muscle activity, pressure pain) was negatively affected, but 15 minutes It was found that the negative effects on the musculoskeletal system were significantly reduced when simple neck stretching exercises were performed in units.
