This study was designed to investigate the effects of 8 weeks of weight-bearing resistance exercise on musculoskeletal disorder symptoms, physical fitness, and stress scale in female call center employees, aged 40 to 50 years. Twenty-two female call center employees, aged 40s to 50s, volunteered to participated in the study as subjects. They were randomly assigned to one of two groups, i.e., weight-bearing resistance exercise (TR; n=11) and control group (CON; n=11). Subjets in TR participated in weight-bearing resistance exercise 3 sessions/week for 8- weeks, whereas subjects in CON were asked to maintain their normal life patterns for same intervention period. Main results of the present study were as follows: 1) Muscular endurance, flexibility, balance, muscular power, and cardiorespiratory endurance improved significantly in TR. 2) Number of musculoskeletal disorder symptoms in neck, shoulder, and wrist reduced significnatly in TR. 3) FMS score in TR increased significantly in TR. 4) ROM of extension, adduction, and internal rotation of both left and right side of shoulder joint increased significantly in TR. 5) ROM of lateral excursion of forearm flexor, right radial deviation, and right ulnar deviation of both left and right side of wrist joint increased significantly in TR. 6) ROM of lateral extension, abduction, adduction, external rotation, and internal rotation of both left and right side of hip joint increased significantly in TR. 7) ROM of left dorsiflexion as well as plantaflexion and abduction of both left and right side of ankle joint increased significantly in TR. 8) Related to perceived stress scale, CES-D, KOSS, and PSS decreased significantly in TR. 9) Concentration of hs-CRP tended to decrease in TR. It was concluded that 8-weeks of weight-bearing resistance exercise would be beneficial for improving work-related musculoskeletal disorders, enhancing physical fitness, and relieving stress and depression in female call center employees, aged 40s to 50s.
