SECONDARY outcome

Timeframe: Baseline and Six Months

Population: Only 10 participants in the Exercise+Placebo group, and 9 participants in the Exercise+Testosterone group, provided baseline and follow-up mPPT measurements.

The Modified Physical Performance Test (mPPT) is a direct observational test that assesses multiple dimensions of physical function (basic and complex activities of daily living \[ADL\]) with different levels of difficulty. The test consists of 9 performance tasks. The total score range is 0-36 (min-max), with higher scores indicating better performance. Sub-scores are assigned for each of 9 item tasks; sub-score range is 0-4 (min-max) with higher scores indicating better performance. The sub-scores are summed to compute the total score.
