简要总结
The present study aimed to investigate whether a daily intake of lupin protein and a neuromuscular electrical stimulation training twice a day can improve local glucose uptake into m. soleus during a 60 day unloading phase with a special unloading device, the HEPHAISTOS orthosis (HEP).
详细描述
The 60 day unloading intervention with the HEPHAISTOS unloading device had the following key objectives:
primary hypothesis:
- Assesment and evaluation of insulin sensitivity and local glucose uptake in the unloaded m. soleus and whether it can be improved by dietary supplementation of lupin seeds and neuromuscular electrical stimulation.
secondary hypotheses:
- Assesment and evaluation of unloading-induced reductions in muscle mass and whether they can be mitigated by dietary supplementation of lupin seed and neuromuscular electrical stimulation.
- Assesment and evaluation of whole-body glycemic effects of the interventions.
