Implementation Of A Combined Exercise Program On Physical Fitness And Health-related Quality Of Life In Women Aged 50 To 59 Years

PURPOSE: The decline in physical fitness and health-related quality of life (HRQoL) is a concern among women aged 50 to 59 years, often worsened by sedentary lifestyles and aging-related changes. Reduced physical activity increases the risk of chronic non-communicable diseases (NCDs) and decreases functionality. Structured exercise programs for this demographic are scarce. This study evaluates the effects of a 16-week combined exercise program on physical fitness and HRQoL in middle-aged women. METHODS: A quasi-experimental study was conducted with a 16-week intervention including aquatic and weight training. The study took place at the University of Guadalajara’s Olympic Pool and Institute of Applied Sciences in Physical Activity and Sports. We enrolled 100 participants aged 50 to 59 years. Participants were randomly assigned to an intervention group (exercise program) or a control group (usual activities). Randomization ensured that participants had similar baseline characteristics in terms of physical fitness level. The study measured muscular strength (handgrip dynamometry), cardiovascular endurance (six-minute walk test), muscular endurance (abdominal endurance test), flexibility (sit-and-reach test), and body composition (bioelectrical impedance). HRQoL was assessed via the SF-36 questionnaire, covering physical function, vitality, and emotional well-being. Baseline and post-intervention measurements were compared using paired t-tests and independent t-tests, with correlation analyses exploring relationships between fitness and HRQoL outcomes. RESULTS: This study is currently undergoing pilot testing. The intervention is expected to improve all physical fitness components in the exercise group compared to the control group. Significant improvements in HRQoL, including physical function, vitality, and emotional well-being, are projected. These gains may contribute to increased independence, reduced NCD risk, and enhanced health perceptions. Improved physical fitness will be positively correlated with HRQoL. CONCLUSION: This study highlights the benefits of structured exercise interventions in improving the physical and psychological well-being of middle-aged women. By demonstrating the effectiveness of a combined exercise approach, this research may guide public health policies and encourage the broader adoption of exercise programs to enhance promoting active lifestyles and healthy aging.
