Open access  Abstract: This study aims to analyze the suitability of different learning theories in the teaching of techniques in combat sports. Through a systematic review of 26 scientific literatures, it examines how observational, constructivist, and social and experiential learning theories compare with traditional theories in terms of effectiveness and applicability. The results reveal that 80% of the reviewed literatures support the superiority of observational, constructivist, and experiential theories. These theories are particularly effective in promoting deep and adaptable learning, enabling athletes to internalize and apply technical skills in real combat situations more effectively. The study’s conclusions suggest that training programs in combat sports should integrate teaching methods based on constructivism and experiential learning to maximize learning effectiveness.

A controlled and randomized clinical trial was conducted with a sample of 20 pregnant women, divided into two groups of 10 participants each. The intervention group practiced adapted Tai Chi for 8 weeks, while the control group did not perform any specific intervention. Physical and psychological variables were measured before and after the intervention period, using validated questionnaires and structured interviews. The results indicate that 90% of the women in the intervention group experienced significant improvements in their quality of life compared to 30% in the control group. Specifically, lower back pain decreased in 70% of t
