Spaceflight causes measures of maximum aerobic capacity to decline, which can result in impaired mission task performance. Based on ISS data, if crew adhere to existing exercise schedules and have access to adequate exercise countermeasure systems, then on average, they return with minimal losses of aerobic fitness. New exploration countermeasures systems will be different from ISS and may not have the capability to support exercise as required to maintain human performance.
