Study type
Interventional
Description of intervention(s) / exposure
The study is a two-arm, randomised controlled exercise intervention trial. Eligible volunteers will be randomly allocated to one of the two eight-month, twice-weekly, 30-minute exercise programs; either a supervised high-intensity progressive resistance training and impact loading group, or an unsupervised home-based low intensity resistance training and flexibility training group.

Arm 1 - Supervised high-intensity progressive resistance and impact training (HiRIT).

Sessions will be supervised by a qualified trainer in a group setting with a maximum trainer to participant ratio of 1:6. Three compound movement exercises using Olympic weights (deadlifts, squats, and presses), along with a weight-bearing impact loading exercise (drop jumps) as per the LIFTMOR protocol (Watson et al., Journal of Bone and Mineral Research, 2017). Five sets of five repetitions will be performed for each exercise and intensity will be progressed to maintain 80-85% 1 repetition maximum and when deemed safe and appropriate by the trainer. Participants will be afforded up to 3 minutes rest between sets.

Training diaries will be used to record participant attendance to training session and to track the weights lifted over the duration of the intervention. Compliance to the training programs will be determined by the number of sessions attended as a percentage of the total number of possible sessions.

Comparator / control treatment
Arm 2 - Unsupervised low intensity home-based exercise (LoHBE).

Sessions are unsupervised and consist of a 10-minute walking warm-up, followed by four stretches (neck, shoulder, side and leg), the neck and side stretches will be performed for 10 seconds each side 2 times while the shoulder and leg stretches will be performed for 60 seconds each side 2 times. The low-load resistance exercises (lunges, sit to stands, calf raises, standing forward raise, toe walks and shrugs), increase with the addition of hand weights (to a maximum of 3 kg) and will be progressed by 1 kg every 12 weeks and performed for 3 sets of 10-20 repetitions. Single leg balance will also be performed by each leg and the complexity will be increased every 6 weeks wither through increase in duration of hold by 10 seconds, an increase in working sets or progressing to eyes closed. The session will finish with a 5-minute walking warm-down. The warm-up and warm-down will be completed between the range of 11-13/20 on the Borg RPE scale. As the training program is home-based participant will be taught all exercises by a qualified trainer in the initial testing session and will be contacted via email monthly to ensure regular contact and adequate progression of the program.

Training diaries will be used to record participant completion of training sessions and to assist the participants to track the progressions of their training. Compliance to the training programs will be determined by the number of sessions completed as a percentage of the total number of possible sessions.

Summary
Brief summary
As a person ages there is a gradual decline in bone health and an increased risk of falling which, when combined, increases the risk of fractures. Weight gain is common after menopause, however weight loss leads to even greater bone loss and greater risk of fractures. This study will help to determine whether the high-load resistance training or home-based exercise are effective strategies for maintaining bone strength and physical function during weight loss.
