Fig. 2From: The effect of long-term confinement and the efficacy of exercise countermeasures on muscle strength during a simulated mission to Mars: data from the Mars500 study a Change in calf MVC across Mars500 was significantly associated with starting calf MVC. Calf MVC was measured every 35 ± 3.6 days in each subject during the 520-day isolation period. b, c Individual changes in MVC where the intervention on average protected against loss of strength and d where no exercise intervention was completed. e Mean (±SEM) calf MVC was increased relative to baseline (day 0) following candidate 70-day exercise interventionsBack to article page
