Study information

Primary study design	Interventional
Study design	Single centre parallel design randomised controlled trial
Secondary study design	Randomised controlled trial
Study type	Participant information sheet
Scientific title	The effects of unilateral neuromuscular stimulation on quadriceps muscle morphology, architecture and function in chronic obstructive pulmonary disease
Study objectives	The overarching hypothesis of this proposal is that neuromuscular electrical stimulation (NMES) results in changes to quadriceps microstructure, architecture and function.
Ethics approval(s)	West Midlands Research Ethics Committee, 11/11/2010, ref: 10/H1208/73
Health condition(s) or problem(s) studied	Respiratory disease (chronic obstructive pulmonary disease)
Intervention	1. Single leg resistance training (control): Three supervised quadriceps resistance training sessions per week for 6 weeks. 2. Single leg neuromuscular elctrical stimulation (experimental): Three supervised and two unsupervised sessions of neuromuscular electrical stimulation per week for 6 weeks. Intervention duration: 6 weeks Total follow up: 6 weeks (time of intervention)
Intervention type	Other
Primary outcome measure(s)	Muscle Mass: quadriceps mass change at 6 weeks
Key secondary outcome measure(s)	1. Neural Adaptations to Training at 6 weeks 2. Muscle Architecture including pennation angle at 6 weeks 3. Muscle Morphology including fibre type at 6 weeks 4. Muscle hypertrophy including satellite cell activity and cross sectional area at 24 hours and 6 weeks 5. Acute local inflammation response at 24 hours and 6 weeks 6. Functional change in quadriceps strength at 6 weeks
