A recent study by the University of Virginia has found that weightlifting could be more beneficial for controlling blood sugar levels compared to traditional cardio exercises such as running.
The research, led by Zhen Yan, focused on understanding how different forms of exercise affect metabolic health. Interestingly, the study found that mice that performed weightlifting-like exercises showed lower blood sugar levels than those that ran on exercise wheels — even though neither group showed significant changes in muscle mass or cardiovascular fitness.
⚖️ Inside the Study: Weightlifting vs. Cardio
The findings, published in the Journal of Sport and Health Science, examined mice that were fed a high-fat diet for eight weeks. The subjects were divided into three groups:
- One group remained sedentary,
- Another performed weightlifting-like resistance training,
- And the third group engaged in running-based cardio activity.
Both exercise groups gained less weight compared to the inactive group. However, the weightlifting group demonstrated improved insulin sensitivity and glucose tolerance, two critical indicators for preventing type 2 diabetes.
Surprisingly, the researchers discovered that these benefits did not come from increased muscle size but from cellular-level changes. Weightlifting helped reduce visceral and subcutaneous fat, indicating that its metabolic effects go beyond visible muscle growth.
💪 Strength Training: More Than Just Muscle Gain
While weightlifting has long been associated with bodybuilding and muscle mass, experts say its benefits extend far beyond aesthetics.
According to Penn Medicine, strength training provides a wide range of physical and mental health advantages.
“There is strong evidence that exercise, including weight training, can help prevent and treat depression,” said Dr. Benjamin Snell of Penn Medicine.
“With strength training, you’re not just giving a boost to your muscles but your bones too,” added Dr. Andrew Brough. “It improves bone density, enhances flexibility in joints, and uplifts your mood.”
So, the next time you hit the gym, don’t limit yourself to the treadmill — adding resistance training could not only help manage weight but also stabilize blood sugar, protect your bones, and boost mental well-being.
