Abstract

Purpose

This study investigated the relationship between habitual nutritional intake and the responsiveness of elderly individuals to resistance training.

Methods

Nineteen participants (66.0 ± 4.5 years) completed body composition (dual-energy X-ray absorptiometry), functional capacity (timed-up-and-go, stair ascent, and stair descent), and neuromuscular tests (5-repetition maximum and countermovement jump) before and after a 9-week resistance training intervention. Habitual nutritional intake was evaluated at the beginning, middle, and end of the intervention. Participants were also divided into two groups based on their protein intake (low protein group < 1.2 g/kg; high protein group > 1.2 g/kg).

Results

Total Kcaloric and protein intake explained ~ 21–44% of the functional capacity improvements, while total Kcaloric and carbohydrate intake explained ~ 21–27% of the change in lean mass. Participants with high protein intake showed greater percentage improvement for timed-up-and-go (− 10.7 ± 4.9% and 0.4 ± 7.4%) and stair ascent (− 11.4 ± 7.6% and − 3.2 ± 5.3%) versus those with lower protein intake.

Conclusion

Nutritional intake influenced individual responsiveness to resistance training in the elderly. Older adults with higher Kcaloric, protein, and carbohydrate intake presented greater improvement in functional capacity and lean mass following resistance training.
