Weight training not just for the young; doctor says it can prevent diabetes

Weight training, often perceived as an activity solely for the young aiming to build muscle mass, is in fact a powerful tool for metabolic health and diabetes prevention across all age groups, according to endocrinologist Dr. Tsai Ming-chieh.

“

I often have elderly patients in my clinic ask, 'I'm already this age, isn't weight training something young people do to build big muscles?' This is a big misunderstanding!

Dr. Tsai highlighted a large-scale study published in JAMA Network Open, which tracked over 140,000 individuals for nearly two decades. The research demonstrated a significant reduction in the risk of developing type 2 diabetes among those who consistently engaged in resistance training. Specifically, performing more than two hours of weight training per week lowered the risk by 27%. The benefits were even more pronounced for those who maintained the habit in middle age (40-60 years), with just half an hour of weekly training reducing long-term risk by a substantial 42%.

The study also clarified that various forms of resistance training are effective, including exercises targeting the upper body or full-body workouts. Dr. Tsai explained that muscles are the body's largest glucose consumers. Muscle contraction during exercise facilitates glucose uptake, thereby improving insulin resistance, a key factor in diabetes development.

Resistance training is not just for looking good; it's a powerful tool for protecting metabolic health and preventing diabetes.

For optimal preventative effects, Dr. Tsai recommends a "golden combination": at least one hour of weight training per week, coupled with sufficient aerobic exercise, and limiting daily sedentary time, such as watching television, to under two hours. Individuals who adhere to all three components can reduce their diabetes risk by an impressive 62%.

Muscles are our body's largest glucose processing factories. As long as muscles contract, they help absorb glucose and improve insulin resistance.

Dr. Tsai encourages individuals, particularly older adults, not to feel intimidated. Simple exercises like wall squats or lifting water bottles in the living room, combined with post-meal walks, can be an effective and accessible way to invest in long-term health and ward off diabetes.

Don't put too much pressure on yourself. Try doing a few wall squats in the living room, lifting water bottles, and taking walks after meals. It's the best investment to stay away from diabetes.
