Comparison of the Effectiveness of Spinning and Resistance Training on Health-Promoting Lifestyle in Overweight Young Women

The present study aimed to compare the effectiveness of spinning and resistance training, as well as their combination, on health-promoting lifestyle behaviors in overweight young women. This semi-experimental study was conducted with 60 overweight women aged 20–30 years, selected by simple random sampling in Najafabad. Participants were randomly assigned to four groups: spinning training (n=15), resistance training (n=15), combined spinning and resistance training (n=15), and a control group (n=15). The interventions lasted eight weeks, with three sessions per week. Health-promoting lifestyle behaviors were assessed pre- and post-intervention using the validated Health-Promoting Lifestyle Profile II (HPLP-II) questionnaire. Statistical analyses included paired t-tests, analysis of covariance (ANCOVA), and Bonferroni post hoc tests at a significance level of p<0.05. ANCOVA results indicated significant group effects on health-promoting lifestyle scores after adjusting for baseline values (F=15.33, p<0.001, partial η²=0.45). Bonferroni comparisons showed that the combined training group achieved significantly higher post-test lifestyle scores compared to spinning (MD=5.21, p=0.028), resistance (MD=7.96, p=0.003), and control groups (MD=21.49, p<0.001). Both spinning and resistance groups also demonstrated significant improvements compared to the control group (p<0.001), while no significant differences were observed between the spinning and resistance groups themselves (p=0.667). These findings confirm that exercise interventions, especially combined modalities, produce large and meaningful improvements in health-promoting lifestyle behaviors. The results demonstrate that spinning and resistance training interventions enhance health-promoting lifestyle behaviors in overweight young women, with combined programs providing the most substantial benefits. These findings highlight the value of integrated exercise strategies as effective non-pharmacological interventions for improving lifestyle-related health outcomes.
