Profiles of resistance training behavior and sedentary time among older adults: Associations with health-related quality of life and psychosocial health()

BACKGROUND: The primary objective of this study was to gain a better understanding of the associations of health-related quality of life (HRQoL) and psychosocial factors (e.g., satisfaction with life, level of self-esteem, anxiety, depression) with resistance training and sedentary behavior profiles. METHODS: For this cross-sectional study, 358 older adults (≥ 55 years of age) across Alberta, Canada, completed self-reported measures of resistance training behavior, sedentary time, HRQoL, and psychosocial health (e.g., depression, anxiety, self-esteem, satisfaction with life). Participants were placed into one of four profiles with respect to their sedentary and resistance training behaviors. Data were collected in Alberta, Canada between August 2013 and January 2014. RESULTS: Pairwise comparisons indicated that those in the low SED/low RT group had a higher mental health composite (MHC) score compared to those in the high SED/low RT group (M(diff) = 3.9, p = 0.008). Compared to those in the high SED/low RT group, those in the low SED/high RT groups had significantly higher MHC scores (M(diff) = 4.8, p < 0.001). Those in the low SED/high RT group reported significantly higher physical health composite scores (PHC) (M(diff) = 3.7, p = 0.019), compared to the high SED/low RT group. Lower depression symptom scores were observed in the low SED/high RT groups compared to the high SED/low RT group, (M(diff) = − 0.60, p < 0.001). CONCLUSION: Resistance training, regardless of sedentary time, was significantly associated with HRQoL and psychosocial health.
