每天散步，腿力為什麼還是越來越差？70歲後只走不練，這3個地方先退化

Why do I still need to use my hands to stand up from a chair even though I walk every day? Why is walking on flat ground no problem, but climbing stairs is becoming increasingly difficult? The problem may not be that you're walking too little, but rather that walking primarily maintains activity level and endurance, and may not adequately stimulate the muscle strength and balance needed for standing up, climbing stairs, and preventing falls. The World Health Organization's recommendations for people over 65 include not only aerobic activity, but also at least two days of major muscle group strengthening exercises per week, as well as diverse activities emphasizing balance and functional strength. This means that walking should be maintained, but it shouldn't be the only form of exercise. The LIFE large-scale randomized trial included 1,635 adults aged 70 to 89 with pre-existing mobility impairments. The interventions didn't just involve walking, but combined walking with lower limb muscle strength, balance, and flexibility training. After an average follow-up of 2.6 years, the structured activity group had a lower risk of developing major mobility impairments. The FAST-2 randomized trial, to be announced in 2026, also found that short but regularly performed functional muscle strengthening exercises can improve chair-standing, balance, and functional performance in some adults with mobility impairments. This video will clearly explain the three areas most prone to problems after age 70: the front of the thighs, hips and glutes, and the calves and ankles; and provide an easy-to-understand weekly schedule and pre-exercise safety screening. Recent data from the U.S. Centers for Disease Control and Prevention shows that approximately one-quarter of people over 65 report a fall each year. Therefore, those with recurrent falls, recent fractures or surgeries, chest pain, significant shortness of breath, or unilateral weakness should first undergo a professional evaluation.
