Arm Intervention/treatment
Experimental: High protein intake
High protein intake: large bolus of protein in teh diet the day before testing
Dietary Supplement: High protein intake
Placebo Comparator: No protein intake
No protein in the diet the day before testing
Other: Placebo comparator
No protein intake
Other Name: control group

Primary Outcome Measures :
  1. Muscle protein fractional synthetic rate following protein ingestion [ Time Frame: 3 hours ]
    The ability of the muscle to synthesise new proteins will be assessed over a 3 h period following protein ingestion and will be compared between groups. This only occurs on one occasion.
