| Abstract: | The aim of this study was to compare the exercise intensity and rating of perceived exertion (RPE) of a high-impact (HIP)
and a low-impact (LIP) university aerobic dance session. Ten women mean (SD) age 22.9 (2.6) years] took part in the study.
An incremental treadmill test was performed by each subject to determine maximum oxygen consumption (V˙O2
max
) and maximum heart rate (HR
max
). The measured V˙O2
max
mean (SD)] was 49.0 (7.5) ml · kg−1 · min−1. The subjects were randomly assigned to LIP and HIP sessions (i.e. five of the subjects participated in the HIP session first,
and the other five participated in the LIP session first). In a laboratory, heart rate, oxygen uptake and RPE were measured
throughout each session for each subject. Expired air was collected continuously throughout the sessions using Douglas bags
(ten bags over a 30-min period). The sessions consisted of 20 min of aerobic exercise (bags 1–7) followed by 5 min of local
muscular endurance exercise (bags 8 and 9) and 5 min of flexibility exercises (bag 10). The mean intensity of the aerobic
section of the LIP and HIP sessions was 51.6% and 64.7% V˙O2
max
, respectively. Ninety-five percent confidence intervals for the average difference between the HIP and LIP sessions demonstrate
that the %V˙O2
max
was between 12% and 14% higher for the HIP session. The mean %HR
max
for the LIP and HIP sessions was 71.4% and 76.7%, respectively, with the %HR
max
in the HIP session being between 5.4% and 7.2% higher on average than that of the LIP session. On average, the RPE for the
aerobic section of the HIP session (12.1) was consistently higher than that of the LIP session (11.1). HIP activity has the
potential to maintain/improve the aerobic fitness of its participants. According to the literature, the exercise intensity
elicited by LIP activity may have a limited training effect for the population utilised in this study, and for some individuals
may result in detraining. Conversely, LIP activities may be an appropriate mode of exercise for overweight and unfit individuals.
