Abstract

Muscle strengthening activity (MSA) is known to have positive physical health benefits. Less is known about MSA and perceived health such as health-related quality of life (HRQOL). The purpose of this study was to investigate the relationship between MSA and HRQOL among adults who are physically active. This study was a cross-sectional survey analysis using HRQOL as the dependent variable, MSA as the independent variable and age, sex, & education as control variables. A total of 523 adults who indicated participating in physical activity (PA) were included in the analysis. HRQOL was assessed using four different measures: 1) CDC’s single general health item, 2) CDC’s Healthy Days Index, 3) SF-36 physical component score (PCS), and 4) SF-36 mental component score (MCS). Data were analyzed by chi-square tests of independence, t-tests, and multiple logistic regression. Adults who participated in both MSA and PA were significantly more likely to report good HRQOL for general health (OR=3.39; CI: 1.66-6.93), unhealthy days (OR=1.62; CI: 1.07-2.47), and PCS (OR=1.99; CI: 1.23-3.22) as compared to adults who participated in PA alone. No significance was seen for MCS. This study found that participation in MSA in addition to PA increases the likelihood of reporting good HRQOL.
