The primary objective is to determine the impact of essential amino acids on integrated muscle protein synthesis over 4 days after resistance exercise.
In addition, the secondary objective is to determine the effect of essential amino acids on satellite cell regulation and inflammatory responses during this prolonged recovery period.

Exclusion Criteria:
4g of maltodextrin
Dietary Supplement: Placebo
4g of essential amino acids
Dietary Supplement: Active

Muscle protein synthesis
Skeletal muscle fractional synthesis rate (%/h) will be determined by oral pulse method using ring-\[D5\]phenylalanine
Time frame: 4 hours
exercise performance
Maximal strength (torque in n-M) of the knee extensors will be assessed by a maximal isometric voluntary contraction (MVC).
Time frame: 4 days
Muscle soreness
Corresponding subjective ratings of muscle soreness will be collected from participants using a visual analogue scale (mm)
Time frame: 4 days
Muscle damage
Muscle damage will be determined by histochemical analysis. muscle damage is defined as Z-band streaming.
Time frame: 4 days
Ran from Oct 2017 to primary completion in Jan 2019, 14 months.
Of 5,147 non-industry interventional studies with no phase under Motor Activity, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 36. This study's 14 months is below that.
Counting every sponsor, half of 5,207 studies reached it within 17 months; a quarter within 7 and three quarters within 36.
