Core Viewpoint - Regular physical activity is essential for health, significantly reducing the risk of chronic diseases such as type 2 diabetes and extending lifespan through optimal exercise regimens [6][12]. Group 1: Exercise and Health Benefits - Exercise is recognized as one of the four pillars of health, alongside sunlight, air, and water, with historical roots tracing back to Hippocrates [6]. - Modern studies confirm that engaging in 60 minutes of moderate-intensity exercise daily can significantly lower the risk of metabolic diseases, particularly when combined with strength training [7][9]. - A recent study indicates a linear relationship between daily exercise duration and the risk of type 2 diabetes, with a reduction in risk of 74% for those exercising over 68 minutes per day [9][10]. Group 2: Optimal Exercise Duration - The World Health Organization (WHO) recommends at least 150-300 minutes of moderate-intensity aerobic exercise weekly, but recent findings suggest that achieving 2-4 times this amount maximizes health benefits [12][13]. - A study covering 116,000 adults over 26 years found that adhering to the higher exercise volume can reduce all-cause mortality by up to 31% [12][13]. Group 3: Strength Training and Aging - Strength training is shown to delay biological aging by an average of 3.9 years, with a recommendation of 90 minutes per week to achieve this effect [15][16]. - Regular strength training can enhance metabolic rate, improve insulin sensitivity, and reduce the risk of chronic diseases such as hypertension and coronary heart disease [15][17]. - The combination of strength training and aerobic exercise yields greater health benefits than either form alone, promoting both muscle retention and fat loss [17].
