Summary
Three training programs improved axillary crutch walking (ACW) speed and metabolic efficiency in women. Despite increased heart rates, perceived exertion decreased, showing enhanced ACW performance.
Area of Science:
- Exercise Physiology
- Rehabilitation Science
Background:
- Axillary crutch walking (ACW) is a common mobility method.
- Understanding the physiological demands of ACW is crucial for effective rehabilitation.
Purpose of the Study:
- To compare the effects of three distinct training programs on physiological and perceptual responses during ACW.
- To assess the impact of training on ACW speed, metabolic efficiency, and perceived exertion.
Main Methods:
- Forty healthy women participated in a six-week study.
- Three training regimens were compared: aerobic arm ergometry, upper extremity strength/endurance training, and ACW training.
- Physiological and perceptual responses were measured during 1 km of ACW at self-selected speeds.
Main Results:
- All training groups significantly increased ACW speed and heart rate.
- Metabolic efficiency improved, indicated by no significant change in oxygen consumption at faster speeds.
- Ratings of perceived exertion decreased despite elevated cardiorespiratory stress.
Conclusions:
- Aerobic arm ergometry, strength/endurance training, and ACW training enhance ACW performance.
- Training improves metabolic efficiency and reduces perceived effort during ACW.
- Cardiovascular screening and speed modification advice are recommended for individuals using axillary crutches.
