Objective: To evaluate the level of health fitness and health-related quality of life (HRQoL) in voluntary square dancers, and to analyze the relationship between them. Methods: Using convenience sampling method, 199 middle-aged and elderly female square dancers in Hangzhou from June to September 2020 were selected as research subjects. Their basic information and HRQoL level were investigated by self-made questionnaires and SF-36 scale, and 7 health fitness indexes such as blood pressure, vital capacity and grip strength were evaluated. Results: (1) The individual conditions of health fitness were as follows: the pass rate of vital capacity was 54.7%, the pass rate of grip strength was 64.3%, the pass rate of sit and reach was 71.3%, the pass rate of dynamic balance was 51.3%, the normal rate of blood pressure was 31.1%, the normal rate of BMI index was 48.2%, and the normal rate of bone mass was 49.2%; The total HRQoL score was 83.63±11.79 (full score 100, unqualified below 60 points), with 5.5% unqualified, 8.0% qualified, 16.1% good, 70.4% excellent. (2) With age and exercise participation as covariates, partial correlation analysis was conducted between healthy physical fitness and HRQoL.There was a significant positive correlation between some indicators of physical fitness (vital capacity, grip strength, sit and reach and dynamic balance) and HRQoL (P<0.05), but none of the correlation coefficients were high. (3) The results of binary Logistic regression analysis showed that participation in other sports, bone health and sit and reach were favorable influencing factors for achieving excellent HRQoL level (P<0.05). Conclusion: Long-term participation in square dancing practice has a positive impact on the health level of exercisers. Despite higher scores in various dimensions of HRQoL and higher quality of life, the results of some indicators of healthy physical fitness are still not satisfactory and yet to be further improved. There are some differences between the results of physical fitness and HRQoL, but they are still positively correlated, among which bone health, flexibility fitness (sit and reach) and participation in other sports are the main factors to achieve the excellent level of HRQoL. |
