Abstract: Differences in fatiguability between human males and females following repeated cycling power outputs has been documented. However, potential differences in muscle oxygenation recovery levels as a potential explanation has not been measured. Understanding differences between male and female muscle oxygenation recovery profiles would be beneficial in establishing both rehabilitation treatment and athletic performance protocols. We hypothesize that females will recover muscle oxygenation levels more robustly than males following 4 x 60s maximal effort cycling bouts with 30s recovery between bouts. Subjects participated in a single day session that included the following: A 4-6 minute warm up on the cycle ergometer (Wahoo KICKR). Four, one-minute maximal effort cycling bouts separated by 30s of recovery between. At the completion of the 4th bout, subjects remained seated on the cycle ergometer for 3 minutes while oxygen recovery levels (Moxy Oxygen Monitor) and blood lactate levels (Lactate Plus) were measured. Heart Rate and Power output were also recorded. Results are pending, but we expect that females will have an enhanced recovery profile compared to males participating in the same exercise.
