Answer

In general patients with LGMD lead a sedentary lifestyle due to their weakness. The effect of endurance training has been only rarely studied.

A study of endurance training on patients with LGMD2I and mild weakness was carried out. The patients cycled for 30 minute training sessions progressing up to a maximum of 5 sessions per week over 12 weeks at 65% of their maximum oxygen uptake. Training significantly improved work capacity, paralleled by self-reported improvements. Creatine kinase levels did not increase significantly, and muscle morphology was unaffected. The authors concluded that moderate-intensity endurance training is a safe method to increase exercise performance and daily function in patients with LGMD2I.

However, this was a small study, performed in only one form of LGMD, has not been replicated and lasted only 12 weeks. The long-term repercussions of endurance training in LGMD are not known and caution should be used in recommending endurance training for patients with LGMD.
