نبذة مختصرة : Background: To test the efficacy of a documented 5-week karate training intervention for rehabilitation and neuroprotection in older adults. Methods: Sixteen older adults (8 male, 8 female, age 59-90y), with or without chronic conditions, participated a 5-week karate training intervention. Dynamic balance, hand grip, ankle plantarflexion force, Timed Up and Go (TUG), and spinal cord excitability (via the soleus H-reflex) were assessed pre- and post-intervention. Results: Participants completed 2437 steps, 1762 turns, 3585 stance changes, 2047 punches, 2757 blocks, and 1253 strikes. Karate training improved dynamic postural performance. The group average time for dynamic postural reaction was reduced (time to target (-13.6%, p = 0.020) and time to center (-8.3%, p =0.010)). TUG was unchanged when considering the entire group (p=0.779), but reductions were found in 5 neurologically intact older adults (-4.5 to -8.6%; pConclusion: 5-weeks of karate training delivered in a fashion to mimic community-level programs provided an effective therapeutic “dose” to improve balance and strength in older adults. Whole-body training embodied in martial arts enhanced neuromuscular function and postural integration. Further quantitative work should explore threshold dose and development of martial arts interventions as functional fitness for older adults.
