Research Focus: Examined muscle tissue building in elderly populations.
Published In: International Journal of Sport Nutrition and Exercise Metabolism.
Cohorts Involved:
Older Adults Group: 17 adults aged 65 to 75.
Elderly Group: 12 adults aged 85 and older, some in their '90s.
Intervention: 12 weeks of resistance training only.
No Changes: Participants did not alter diet, supplements, or medications during the study.
Assessment Points:
Before the start of the training.
6 weeks into the training.
At the end of the 12 weeks.
Metrics Measured:
Muscle size or volume.
Muscle efficiency or strength (weight lifting ability).
Body Composition Changes:
Both groups experienced a slight reduction in whole body fat mass.
Improvement in whole body lean mass, especially in appendicular lean mass (arms and legs).
Muscle Performance:
Both muscle volume and strength improved in all participants.
Improvements were similar between both age groups despite the initial difference in fitness levels.
Quadriceps Improvement:
85-plus age group saw equal or slightly better improvements in quadriceps compared to the 65 to 75 age group.
Key Findings:
Possible to gain muscle and enhance strength at any age.
Improvement potential in muscle growth and strength remains consistent across ages.
