Brief summary
As we age, the quality and strength of muscles and bone diminishes. Furthermore, changes in posture and musculoskeletal dysfunction, such as rotator cuff pathologies, can accelerate this deconditioning. Resistance training is recommended in older adults to try to slow the rate of decline and maintain strength and function, however the minimum National Physical Activity Guidelines are only being met by approximately 1 in 4 Australian older adults, with no indication that the resistance guidelines are being met. This project aims to investigate the most effective upper limb resistance exercise equipment to use for maximal range of motion and muscle activation of the targeted muscle(s) in older adults. Participants will be asked to attend a single testing session, where they will perform six upper limb exercises without resistance and then using elastic banding (Theraband), milk bottles and resistance machines. Total range of motion and muscle activity will be measured for each exercise, using each piece of resistance equipment, on the major muscles in the arms and chest. The order of exercise completion and the item of equipment used will be randomized between each participant. The results of this study will provide further insight for exercise professionals to prescribe home-based upper limb resistance exercises in older adults, taking into consideration the type of resistance equipment, that will allow for the greatest activation of the targeted muscle(s).
Interventions
Participants will attend a single testing session, lasting for a maximum of 2 hours and will be asked to perform six different upper limb exercises, being a biceps curl, shoulder press, lateral raise, triceps extension, chest press and upright row. Peak upper limb muscle activation and range of motion will be measured during performance of the six exercises using three different types of resistance equipment (milk bottles, cable machine and theraband) with a resistance of 4kg. A single set of 10 repetitions will be performed for each exercise, for each item of equipment. Sessions will be conducted 1:1 by student exercise physiologists, under the supervision of an Accredited Exercise Physiologist. Following completion of each set, participants will be asked to rate their perceived exertion following the bout of exercise. The order of exercises and the order of equipment used will be randomised for each participant. No washout period will occur.
