본 연구는 성인 지적장애인의 수영프로그램 참여에 따른 건강관련 지표들의 특징을 규명하고자 수행되었다. 이를 위해, 부산지역에 거주하고 있는 20-39세 사이의 성인 지적장애인 20명을 선정하였으며, 수영프로그램에 참여한 운동군 10명과 동일한 기간 특별한 신체활동에 참여하지 않고 일상적인 생활을 해 온 통제군 10명의 두 집단으로 분류하였다. 대상자들의 건강체력, 스트레스 호르몬 및 면역기능을 측정하여 자료를 수집하였으며, 자료분석은 SPSS 18.0을 이용하여 대응 t-test, 독립 t-test 및 two-way ANOVA를 실시하였다. 그 결과 운동군에서 근력(p<.001), 근지구력(p<.001), 유연성(p<.001), 심폐지구력 (p<.01) 향상에 유의한 차이가 있었고, 통제군은 유의한 차이가 나타나지 않았다. 스트레스 호르몬인 코티졸(p<.01)은 운동군에서 유의하게 감소하였고, 통제군에서는 유의한 차이가 없었다. 면역글로블린인 IgA(p<.05), IgG(p<.001), IgM(p<.05)은 운동군에서 유의한 증가가 있었고, 통제군에서는 유의한 차이가 나타나지 않았다. 따라서 규칙적인 수영프로그램은 성인 지적장애인의 건강체력 향상에 매우 효과적인 운동프로그램이라 할 수 있으며, 스트레스를 감소시키고 면역기능 개선에 도움을 줄 수 있음을 보여주는 결과로, 향후 성인 지적장애인들의 건강유지와 만성질환 예방을 위해 적극적인 신체활동 프로그램 개발과 중재의 필요성을 시사한다.

This study investigated the relationships between Work-related musculoskeletal disorders (WMSDs), contributing factors, and the occupational stress of physical therapists. Self-reported questionnaires were given to 180 physical therapists in Gangwon Province. Variables examined included the prevalence of pain sites related to WMSDs; pain intensity; pain pattern; and job stress, which is thought to involve the physical environment; job demand; insufficient job control; interpersonal conflict; job insecurity; organizational system; reward system; and occupational culture. Among physical therapists, work-related musculoskeletal pain commonly affected the low back (30.1%), shoulder (29.3%), and wrist (12.2%). The sites of work-related musculoskeletal pain treated medically were the low back (22.8%), shoulder (19.8%), neck (12.7%), and wrist (12.1%). "Repeating the same work constantly" was suggested to be the major cause of the pain. The younger therapists were significantly more likely to feel high job stress due to the physical environment (p<.05), job demand (p<.05), and organizational system (p<.01). Women were more likely to feel greater job stress related to job demand, insufficient job control, the organization system, and job rewards. Men were more likely to feel greater job stress related to job insecurity. Weak positive relationships were observed between work-related musculoskeletal pain and job stress, which is thought to involve the physical environment; job demand; insufficient job control; interpersonal conflict; job insecurity; organizational system; reward system; and occupational culture. Physical therapists appear to be at higher risk of WMSDs because 80.1% of the physical therapists studied experienced work-related musculoskeletal pain. To reduce the risk, we need intervention strategies such as preventive education, ergonomically designed medical equipment, a psychosocial approach to work conditions, improved mechanical conditions related to therapeutic patterns, and an institutional infrastructure with sufficient personnel and scheduling.
