International Journal of Exercise Science 7(4) : 278-285, 2014. To evaluate if resistance training can reach Moderate to Vigorous Intensity (MVI) and contribute to the aerobic component of the international physical activity guidelines. Sixteen participants aged between 20 and 35 were recruited. Heart rate was recorded by heart rate monitor during a resistance training program. Based on maximal heart rate, time spent at MVI (55-69% of maximal heart rate) was calculated. Participants displayed a HR equal or above MVI for 51.5% ± 21.7% of time. When stratifying by lower and upper body sessions, that proportion was median (25-75th); 75.0% (32.5%-89.2%) and 45.8% (30.0%-66.8%) respectively. Body mass (r=.68; p<.01), body mass index (r=.54; p=.03), and leg press strength (r=.59; p=02) were positively associated with time spent at MVI. Assuming 10-minute bouts of aerobic exercise are not needed to achieve health benefits, it is possible to reach MVI with resistance training. Emphasis on the importance of performing resistance training should be done to reach the aerobic component of the physical activity guidelines and optimize health benefits. This provides an alternative option to those who may have difficulty or be unable to reach the required aerobic intensity by traditional aerobic exercises.
