Twelve-Weeks of Virtual and In-Person Exercise Training Improve Static and Dynamic Balance in Female Cancer Patients
Abstract Background: Balance is important for maintaining activities of daily living and functional independence. Whether balance is improved in cancer patients after fitness training is unclear. The purpose of this study was to determine if 12-weeks of exercise improves balance and posture in female cancer patients. Methods: Thirty-eight female cancer patients were enrolled. Of the 16 patients who completed the program (mean age±SD: 65±10 years), 12 participants were novice and 4 were experienced exercisers. Six-weeks of exercise sessions were provided in-person and the remaining sessions were virtually delivered. The American College of Sports Medicine’s exercise recommendations were followed. Novice exercises received 36, 90-minute exercise sessions (3x/week) and experienced exercisers had 24, 90-minute sessions (2x/week). Posture was measured using the plumb line method and overhead squat test; balance was measured using the unipedal single leg stance and limits of stability (LOS). Body composition, cardiorespiratory fitness, muscular strength, and flexibility were also measured. Two-way repeated measures ANOVAs and Bonferroni’s multiple comparison tests were used to determine significant differences. Results: Balance on the left leg (eyes closed) and LOS with leftward excursion were significantly improved in experienced exercisers (P=0.0029), but not in the novice group (P=0.0013). Qualitative data showed that experienced exercisers had improved static and dynamic postural alignment of the lower body. Conclusions: While cardiorespiratory and muscular fitness significantly improved in the novice group, these patients did not show balance and postural improvements. Only the experienced exercisers had significant improvements in static and dynamic balance and lower body posture.
