• A new BMJ Open Sport and Exercise Medicine study investigated how one year of supervised high-intensity weight training impacts muscle function and size in older adults over three years. 

• It compared this to moderate-intensity training and a control group.

• Randomized controlled trials were conducted on 451 adults at the retirement age (64-75 age bracket) at a University Hospital in Denmark.

• The results were assessed at the Baseline, post-1-year intervention, two years, and four years post-study start.

• The results depicted that heavy resistance training for one year in healthy adults of age may have a long-lasting beneficial impact on muscles by preserving muscle function.

• Overall, this study underscores the potential of heavy resistance training to preserve muscle function and prevent functional decline in older adults, highlighting an effective strategy for promoting healthy aging and reducing healthcare costs
