简要总结
Eleven men with myotonic dystrophy type 1 (DM1) underwent a 12-week lower-limb strength training program. The training program consisted of 3 series of 6 to 8 maximal repetitions of 5 different exercises: Leg extension, leg press, hip abduction, squat and plantar flexion. Training sessions were closely supervised and took place twice a week. It is hypothesised that the training program will induce muscular hypertrophy despite the genetic defect. The training program should also have positive effects on function. The participants were evaluated at baseline, week 6, week 12, month 6 and month 9 to see the effects of the training program and if these effects are maintained over time.

盲法说明
Most outcomes where not masked, however the outcome assessor was masked for all muscle biopsy analysis: while analysing the muscle biopsy outcomes, the outcome assessor did not know if it was from baseline or from after the training program.
