Description:
This research's main objective was to determine aerobic capacity in Mexican American young adults. Aerobic capacity was measured using a submaximal treadmill exercise using the Bruce protocol. Sixteen male and five female healthy student volunteers aged 22-30 participated in the experiment. Volumetric oxygen consumption was measured using the breath-by-breath VMaxST oxygen consumption monitor. Results indicate that Mexican American men had a VO"2"m"a"x of 4.8l/min (SD=1.75) and a weight adjusted VO"2"m"a"x of 56.32ml/kg/min (SD=12.2), while Mexican American women had a VO"2"m"a"x of 2.8l/min (SD=0.73), and a weight-adjusted VO"2"m"a"x of 44.69ml/kg/min (SD=6.72). Results also indicated that the heart rate was nearly 10 times the rating of perceived exertion at each workload. Relevance to industry: Given the changing demographics of the US population, and the work force becoming predominantly Hispanic, it is important to quantify the aerobic capacity of Mexican American young adults for work design.
