Stretch breaks in the work setting improve flexibility and grip strength and reduce musculoskeletal complaints

摘要

AbstractThis study investigated the effect of a stretch break program (SBP) on the flexibility, strength and musculoskeletal complaints of storage (SW) and administrative (AW) sector workers. Twenty-six male workers were randomly selected: 16 workers from the storage sector and ten workers from the administrative sector. We applied the Physical Activity Questionnaire and Musculoskeletal Questionnaire and evaluated flexibility and grip strength before and after 6 months of the SBP. The SPB decreased the SW group members' complaints of paresthesias and numbness in the upper body and total body. The SPB reduced the AW group members' complaints of paresthesias and numbness in the upper body. Furthermore, the SPB improved cervical, trunk and left shoulder flexibility in the SW group and improved cervical and shoulder flexibility and grip strength in the AW group. The SBP contribute to improve flexibility and musculoskeletal complaints in the regions that are affected by higher rates of work-related injuries.
