Prospective Study for 24-months of Physical Training Introduced in Lifestyle of Patients With FSHD : Tolerance, Sustainability and Efficiency of Unsupervised Training Program.

The training will consist in 3 sessions of 35 min of training per week at home on an ergocycle. The training will be divided in (i) 2 sessions of 30 min aerobic exercises at a constant but moderate (60% of maximal aerobic power, MAP) intensity followed with 5 sets of 10 revolutions at near-maximal intensity and (ii) an interval-training session. This latter session will consist in 5 min warm-up at 40% MAP followed by 5 times 1 min at 80% MAP (recovery = 4 min at 40% MAP) followed by 5 min of active recovery. A systematic supervision of the sessions by the coach will be performed by phone, by using the heart rate recordings and values of Analogic Visual Scale for pain and fatigue.
