Effects of strength/endurance training on functional and biochemical capacity in older adults
Keywords:
strength/endurance, functional capacity, biochemical capacity, older adultAbstract
Introduction: Positive changes in the physical, functional, and metabolic health of older adults involve the implementation of a physical stimulation program, which involves the improvement of muscular strength and cardiovascular endurance.
Objective: To improve functional capacity and biochemical parameters in older adults through a strength/endurance training program tailored to their needs.
Methods: Descriptive/explanatory correlational research studying a sample of older adults (n=35; 63-70 years) participating in an intervention program with strength/endurance stimuli (12 weeks, 5 phases). The effects on functional and biochemical indicators were assessed.
Results: Functionally, hand grip strength (+20.5%), lower limb strength/endurance (+37.8%), aerobic endurance (+15.9%), balance (+51.2%), as well as mobility and the risk of falls (-22.2%) improved. Biochemically, indicators such as blood glucose (-5.3), pH (+0.2), cholesterol (-15.4), chronic inflammation (-48.6%), and lactate stored in blood (-0.6) improved. All tests were significantly different in favor of the post-test (p<0.05).
Conclusions: The adapted strength/endurance program has significant positive effects on biochemical and functional capacity parameters. Improvements in glucose, cholesterol, lactate, and pH reflect the metabolic benefits of exercise, while improvements in strength, endurance, mobility, and balance indicate a positive impact on functional health. There is a need to promote physical exercise among older adults to improve their overall health and quality of life.
