Objective: To determine if seniors living in care homes can delay the progression of age related muscle loss with exercise and adequate amount of proteins, >20 g, when consumed after an exercise session.

Method: A twelve week study, (N = 13) was conducted in seniors (73–105 y). The inclusion criteria in the study were adequate cognitive function to follow exercise directions and a renal function of GFR > 30. A 2-day/week, resistive, seated exercises program was conducted by Kinesiologists. The participants were randomly assigned to receive a protein shake, with 39 g of whey protein isolate, or a placebo effect drink after each session. The initial measurements were taken for hand grips, timed up and go, and five times sit to stand, and compared with the measurements taken after the twelve week time period.

Results: In the Sit to Stand test control group showed a mean decrease in time of 2.89 (SD = 6.42) seconds and the treatment group showed an increase of 3.68 (SD = 5.17) seconds to complete the test. In the timed up and go the control group increased time by 0.252 (SD = 9.9) seconds and the treatment group increased time by 1.63 (3.56) seconds. For grip strength control group showed a mean improvement of 2.72 lbs (SD = 8.25) in their right hands and a mean improvement of 0.6 lbs (SD = 2.02) in their left hand. The treatment group showed a mean decrease of 2.075 lbs (SD = 8.31) in their right hands and a mean decrease of 0.44 lbs (SD = 4.62) in their left hands.

Conclusion: Based on our sample size (N = 13) and intersubject variability, we were unable to show any statistical difference in the control or the treatment group. However, looking at individual results, subjects in the treatment group showed more improvements in one or all three measures compared to individuals in the control group.
