Effects of Different Interventions Using Boxing, Taekwondo and Elastic Band Training on Body Composition and Physical Performance in Chilean Older Women

The objective of this clinical trial is to compare the effect of three physical interventions (Taekwondo, Boxing, and Elastic Band Training) on body composition and physical performance in older Chilean women. The main questions this study aims to answer are: How do Taekwondo, Boxing, and Elastic Band Training affect body composition (body fat percentage and fat-free mass)? What improvements are observed in physical performance (grip strength, balance, flexibility, and cardiorespiratory fitness) with each intervention? Researchers will compare the effects of these three interventions to determine which offers the greatest benefits for body composition and physical performance. Participants will: Perform Taekwondo, Boxing, or Elastic Band Training twice a week for 8 weeks. Be assessed for morphological and physical performance variables before and after the intervention period. Participate in supervised training sessions at local sports centers. This study aims to provide solid evidence on the efficacy of different physical interventions in improving the physical health of older women, helping to define more effective and accessible training strategies.
