High Intensity Strength Training
The strength-training intervention will consist of 5-min warm-up, 40-min training, and 15-min cool-down. The 60-min sessions will be conducted 3 times/wk for 18 months. Every 2 weeks the load lifted will be adjusted so that the participants in this group are lifting 3 sets of each exercise at 75-90% of 1RM.
Low Intensity Strength Training
The strength-training intervention will consist of 5-min warm-up, 40-min training, and 15-min cool-down. The 60-min sessions will be conducted 3 times/wk for 18 months. Every 2 weeks the load lifted will be adjusted so that the participants are lifting 3 sets of 15 repetitions at 30-40% of 1RM.
Attention Control
Participants in the control group will attend 60-min organized workshops 2 times/month for the first 6 months and then 1 time/month for months 7-18.
