The trends in the fitness industry over the last decade have led to the development of a variety of unique and innovative types of equipment. One of the most popular exercise machines is the stairclimber, or sometimes called the stairmaster. When compared to the motor-driven treadmill, the stairclimber has been touted to provide a better aerobic workout while simultaneously increasing muscle strength and lowering injury rates. Given that the main objective of many individuals engaging in aerobic exercise is to expend calories thus leading to weight loss, the situation poses an interesting and logical inquiry. The purpose of this study was to determine whether there was a significant difference in caloric expenditure while exercising on a motor-driven treadmill versus a stairclimber. The participant group for this study included 15 apparently healthy women with the following physical characteristics: age(years) M = 20.1, SD = 2.4, height(cm) M = 163.3, SD = 6.6, weight(kg) M= 67.3, SD = 15.4 and resting heart rate (bpm) M = 66.7, SD = 7.9. The participants were randomly divided into two groups. Each group performed two 15-mm bouts of exercise at a target heart rate of 60% to 70% using a motor-driven treadmill (Trotter Supertrainer 585) followed by a stairclimber (Trotter 330) or vice versa. …
