Study type
Interventional
Description of intervention(s) / exposure
The study is a three-arm, semi-randomised controlled exercise intervention trial. Eligible volunteers will be randomly allocated to one of two eight month, twice-weekly, 30-minute exercise programs; either supervised heavy progressive resistance training and impact loading, or machined-based isometric resistance training using the bioDensity system.
Arm 1 – supervised heavy progressive resistance training and weight-bearing impact loading.
Three compound movement exercises (deadlift, overhead press, and squat) using olympic weights will be completed. For each exercise, 5 sets of 5 repetitions, corresponding to an intensity of 80-85 % of 1 repetition maximum will be performed. 5 sets of 5 repetitions of weight-bearing impact loading exercises (i.e. drop jumps) will also be performed, with height of the jump progressively increasing across the intervention period.
Arm 2 – supervised high-load isometric exercise using the bioDensity system.
A single set of four isometric exercises (chest press, leg press, core and arm pull, and vertical lift) will be performed according to bioDensity device specifications. For each exercise, one repetition of a self-initiated 75%-maximum contraction will be held for 5 seconds.
Sessions are supervised by a single qualified trainer (Bachelor of Exercise Science with Honours, Level 1 Sports Trainer, Certificate III in Fitness), a PhD candidate in the School of Allied Health Sciences.
Training diaries will be used to record participant attendance at exercise sessions, and the completion of each element of the training session. Compliance will be determined as the number of sessions attended as a percentage of total possible sessions.

Comparator / control treatment
Arm 3 – the comparator will be a non-randomised sample of men, recruited independently but sex- and age-matched to the exercise arms. They will simply continue with their usual activities for 8 months, but will undergo the identical testing protocol at baseline and follow-up as the two randomised arms. Weekly email contact will be maintained to approximate investigator exposure and track alterations to habitual diet or physical activity levels over the 8 month period.

Diaries will be provided and all participants will be encouraged to record any changes to medication, medical conditions and general health.

Summary
Brief summary
Recent work undertaken at Griffith University (the LIFTMOR trial) has revealed that brief exposure to a bone-targeted heavy progressive resistance training program is both safe, and effective for enhancing musculoskeletal health and function, in postmenopausal women with low to very low bone mass. Similar claims have been made by the developers of the bioDensity system, designed around the premise that low volume machine-based isometric resistance training produces beneficial effects on balance, physical function, muscle strength and bone mass. Whether dynamic or isometric resistance training will be more effective in middle-aged and older men with reduced bone mass at the hip and spine remains to be seen.
