Resistance Training Plus Amino Acids Beat Either Alone for Muscle in Older Women
In healthy women aged 65 and older, combining resistance exercise with essential amino acid supplements for 12 weeks increased muscle mass more than doing either one alone. The combo group also showed the biggest improvements in fitness tests and the best shift in muscle-related hormones. Inflammatory markers dropped too, with one key marker only declining in the combined group. Each intervention helped on its own, but pairing them produced clearly stronger results.
Key Insight
This study suggests pairing resistance training with amino acid intake may better preserve muscle in older women.

Staying Active From Midlife Cuts Sarcopenia Risk by Up to 78%
In Norwegians tracked for over 30 years, those who stayed active from middle age into their 70s had 78% lower odds of confirmed muscle loss. Even people who started exercising later in life saw meaningful benefits. People who became inactive lost most of the protection.
Low Vitamin D Linked to Muscle Loss, Especially in People With Diabetes
In a study of over 7,500 older adults, low vitamin D was tied to higher odds of sarcopenia (age-related muscle loss). The link was stronger in those with diabetes. In aged diabetic rats, vitamin D3 supplements improved muscle strength and reduced fat buildup inside muscle fibers.
Two Hours of Weekly Strength Training Hits the Sweet Spot for Longevity
In nearly 150,000 adults tracked for up to 30 years, doing 90 to 119 minutes of strength training per week was linked to a 13% lower risk of dying from any cause. More than two hours weekly added no extra benefit. Combining strength work with aerobic exercise gave the biggest mortality drop.
