Active old rats supplemented with soluble milk protein exhibited higher locomotion parameters.

<p>Assessment of short-term exploration activity using an IR actimeter with 19-month-old rats after two months of protein supplementation with a concomitant low-intensity physical activity program revealed that locomotion capacities were higher for the PRO than for the CAS group. Indeed, active old rats supplemented with soluble milk protein exhibited higher values in terms of the total number of movements and the distance travelled (<i>A</i>) and the average speed (<i>C</i>), than CAS group. Values are means ± SEM. ^<i>c</i> p<0.05 <i>vs</i>. the CAS group.
