The purpose of this study is to investigate the effect of CK-2127107 versus placebo on skeletal muscle fatigue assessed as change from baseline versus 14 days of treatment in sum of peak torque during isokinetic knee extensions.
This study will also assess the effects of CK-2127107 on physical performance via a short physical performance battery (SPPB), stair-climb test and 6 minute walk test.

Experimental: CK-2127107, then Placebo
Participants will first receive CK-2127107 tablets (twice daily) for 14 days. After a 14 day wash out period participants will then receive matching placebo.
Other Name: CK-2127107
Experimental: Placebo, then CK-2127107
Participants will first receive Placebo tablets (twice daily) for 14 days. After a 14 day wash out period participants will then receive matching CK-2127107.
Other Name: CK-2127107
- Change from period baseline in sum of the peak torque of 120 contractions [ Time Frame: Baseline, Day 1 and Day 14 of Treatment Periods 1 and 2 ]Peak torque measurements will be obtained with the participants seated and the knee extended through a determined range of motion. Peak torque (Nm) will be measured at 120°/second with 120 isokinetic contractions.
- Change from period baseline of Short physical performance battery (SPPB) score [ Time Frame: Baseline, Day 1 and Day 14 of Treatment Periods 1 and 2 ]Each of the 3 performance measures will be assigned a score ranging from 0 to 4, with 4 indicating the highest level of performance and 0 the inability to complete the test. A summary score (range 0-12) will be subsequently calculated by adding the 3 scores.
- Change from period baseline of stair-climb test [ Time Frame: Baseline, Day 1 and Day 14 of Treatment Periods 1 and 2 ]Participants will be asked to ascend a set of 10 stairs. The participants will be asked to ascend the stairs 1 step at a time as quickly as the participant can while remaining safe. Time will be recorded as seconds.
- Change from period baseline of distance walked assessed by 6-minute walk test [ Time Frame: Baseline, Day 1 and Day 14 of Treatment Periods 1 and 2 ]Participants will be instructed to walk as far as possible in 6 minutes, walking back and forth around the turn points. The distance will be recorded in meters.
