Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
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.

Comparator / control treatment
Prior to completing the intervention, participants will act as their own controls for the study. They will be asked to performed unweighted exercise (active range of motion, without equipment) to determine peak muscle activation and maximum joint range of motion at baseline. These results will act as a comparative, to determine the difference that the added resistance of the three pieces of equipment have on muscle activation and range of motion.

As part of the same 2 hour intervention period, participants 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 using no resistance equipment. A single set of 10 repetitions will be performed for each exercise. Sessions will be conducted 1:1 by student exercise physiologists, under the supervision of an Accredited Exercise Physiologist. Following completion of the set, participants will be asked to rate their perceived exertion following the bout of exercise.

Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation sequences for each participant will be concealed in double opaque envelopes, with allocation off envelopes occurring in sequential order by time of attendance. Due to the nature of the study, researchers and participants will not be blinded to their allocation, as both will be aware of the type of equipment being used and the exercise they are being asked to perform.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The order of exercises and the order of resistance equipment used will be randomized for each participant, as there will be a learning effect as the exercise technique becomes more familiar to the participants. Each exercise will be assigned a number from 1-6, and each item of equipment with receive a number 1-3, with the randomisation sequence of exercises and equipment being generated by a website (randomizer.org). The assigning of numbers to the exercises and equipment will be done by a list randomizer (random.org/lists/) to ensure objectivity.

Statistical methods / analysis
Analysis will be conducted using de-identified data. Summary statistics will be generated for the variables collected in the study, using IBM SPSS software. Descriptive analysis will be performed on numerical demographical data and frequency analysis for all categorical demographic data. T-tests will be used to compare between variables. Descriptive statistics will be presented as mean ± standard deviation (SD), or median (interquartile range) where appropriate. An alpha of P < 0.05 will be used to denote statistical significance.

Summary
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).
