Stair-climbing ergometry has become a popular mode of aerobic exercise, yet little research on the biomechanics of stair-climbing ergometry has been reported. This study was conducted to evaluate kinematics and myoelectric activity in major agonist muscle groups over 22 minutes of stair-climbing ergometry at 75% of each subject's predicted VO2max. Data were captured over 30-second intervals beginning at 3.5, 9.5, 15.5, and 21.5 minutes of exercise. Multivariate analysis of variance for the kinematic variables revealed a significant (p < 0.05) change in hand placement from a higher to a lower position over time. Multivariate analysis of variance for the electromyographic values revealed a significant (p < 0.05) decrease in activity in the gluteus maximus and vastus lateralis between 3.5 and 9.5 minutes, representing an adjustment to the exercise workload. The normal range of motion and trunk angle values documented should prove helpful to fitness and rehabilitation specialists in prescribing stair-climbing ergometry.

D015444	Exercise	Physical activity which is usually regular and done with the intention of improving or maintaining PHYSICAL FITNESS or HEALTH. Contrast with PHYSICAL EXERTION which is concerned largely with the physiologic and metabolic response to energy expenditure.

D016552	Ergometry	Any method of measuring the amount of work done by an organism, usually during PHYSICAL EXERTION. Ergometry also includes measures of power. Some instruments used in these determinations include the hand crank and the bicycle ergometer.	Ergometries
D018482	Muscle, Skeletal	A subtype of striated muscle, attached by TENDONS to the SKELETON. Skeletal muscles are innervated and their movement can be consciously controlled. They are also called voluntary muscles.
