RESUMEN
Physical exercise improves the physical condition of women who have been undergone surgery for breast cancer. This study evaluated the effect of a new martial arts program that combined aerobic endurance and muscle strength exercises on improving upper limb function and aerobic performance of women who have undergone breast cancer surgery. Fifty-three women who had previously undergone breast cancer surgery with axillary lymph node dissection, radiotherapy and/or chemotherapy participated in the twelve-week program. Participants were randomly assigned to two groups; a study group (28 participants) in which participants carried out a synchronized pedaling with martial arts routine of 2 sessions per week, and a control group (22 participants) who received usual care. Study group participants demonstrated a significant increase in right hand and quadriceps strength, maximum oxygen consumption, max power-to-weight ratio, muscle mass percentage and a decrease in fat mass percentage (p≤0.05). A controlled training system like synchronized pedaling with martial arts, which combines aerobic and strength exercises, appears suitable for improving the muscle strength and aerobic capacity of these breast cancer participants.
