Abstract

Nine (3 women and 6 men) healthy CrossFit affiliates, participated in a V02max test before participating in the CrossFit workout of the day (WOD) ‘Cindy’. During the WOD, participants completed one session, consisting of 5 pull ups, 10 push ups and 15 body weight squats, the aim being to complete as many rounds as possible (AMRAP) in 20minutes. A Cosmed K4b2 was worn to collect breath by breath pulmonary gas exchange, HR and energy expenditure figures. HR was measured and RPE taken after every round and an overall RPE of the workout was taken. The main aim was to determine the energy expenditure and relative intensity of the CrossFit workout Cindy. Major conclusions indicated that Cindy meets energy expenditure recommendations of the ACSM guidelines to achieve between 150-400kcals per exercise session for weight maintenance. Participants elicited a total expenditure of 293.5 ± 84.1kcals in the 20 minute workout. Men were working at V02avg of 62.4 ± 5.9ml.kg-1.min-1 and women 48.1 ± 13 ml.kg-1.min-1, this indicates women were working at a higher %V02max (61%) throughout the session than men (57%). Participants were working at 83%HRmax respectively. Major conclusion is the workout Cindy meets the moderate category for %V02max and the vigorous category for %HRmax.
