Study information
Scientific title
Acronym
Study hypothesis
Older people with a history of hip fracture often have generally low muscle strength and power in the lower limbs, especially on the fractured side, which may result in mobility limitations. This considerable asymmetrical deficit may further complicate balance and independent living.
Progressive strength-power training may increase muscle strength and power. Taking into account asymmetrical deficit in the lower limbs may lead to larger improvements in mobility function in older people than conventional strength training.
Ethics approval
The study was approved by the Ethical Committee of the Jyväskylä Central Hospital Board on 14/10/2004
Study design
A randomised controlled trial; men and women randomised in blocks. Data collected in two phases using the exact same protocol equipment and staff.

Hip fracture
Intervention
Participants assigned to the intervention groups, participated twice a week in a 12-week progressive strength-power training specifically designed to increase lower limb muscle strength and power and to reduce asymmetry in lower limb strength and power. Resistance equipment was used to train: leg press, knee flexion, hip abduction and adduction exercises, in addition, plantar flexion exercise was provided by means of a weighted vest. The one repetition maximum (1 RM; calculated from the observed 3-5 RM) for the exercises used in the training was assessed twice during the training. The resistance of the strength training (usual velocity) was progressively increased from 50 to 80 % of the 1RM of the respective leg. Leg press and plantar flexion exercises were trained in addition with high-velocity low-load resistance (power training). For these exercises, the number of repetitions was progressively increased. In order to equalise muscle strength and power asymmetry between the legs, the weaker leg was trained with more sets of repetitions and/or a higher percentage of resistance. The training was supervised by an experienced physiotherapist.
The participants assigned to the control group were encouraged to continue their lives as they were used to.

Target number of participants
30 participants in each group (60 in total)
Participant exclusion criteria
The criteria of American College of Sports Medicine (e.g. severe cardiovascular disease) were used to exclude people from participation in the randomized controlled trial. Additionally, severe progressive (e.g. cancer) or neurological disease (e.g. advanced Alzheimer's disease), lower limb amputation, inability to walk outside without assistance of another person and alcohol abuse were used as exclusion criteria for this study.
