Peak cycle! A flashback from my cycle test 5 days after return to Earth from the @Space_Station. A mask collects the air we exhale to measure the amount of CO2 we exhale (our metabolic rate), and electrodes measure our heart rate and rhythm. Our scientists and doctors use these data to ensure all is well with our cardiovascular snd respiratory systems.

Just 5 days after landing and I exceeded my performance from my last test before the flight! Yet another indication that our exercise equipment on the ISS not only maintains, but can increase our fitness level even while in microgravity.
