A study at McMaster University examined the issue of amount of resistance, relative to post-exercise increases in muscle protein synthesis rates and differing nutritional support, as predictors of long-term training-induced muscle hypertrophy. The goal was to test whether the same was true with short-term, exercise-mediated changes in muscle protein synthesis.
18 men were randomly assigned to two of three leg-training conditions that differed in contraction intensity (percentage of a 1-repetition maximum [1RM]) or contraction volume (one to three sets):
Group 1 – 30% of a 1RM @ three sets to volitional muscular fatigue (VMF).
Group 2 – 80% of a 1RM @ 0ne set to VMF.
Group 3 – 80% of a 1RM @ three sets to VMF.
The subjects trained each leg with their assigned exercise prescription for 10 weeks at 3 training sessions per week. They took pre- and post-training measures of strength, muscle volume by magnetic resonance (MR) scans, pre- and post-training biopsies of the vastus lateralis (one of the quadricep muscles), and a single post-exercise (1-hour) biopsy following the first bout of exercise, to measure signalling proteins…The Trainer Boxing/Functional Training Club Hood River http://www.thetrainerhoodriver.com #thetrainer #hoodriver#personaltrainer #functionaltraining #functionaltrainer#rusticparkour #psychology #muaythai #fitness #functionaltrainer #health #running #fitnessaddict #workout #cardio #mma #training #healthy #parkour #boxingfunctionaltrainingclubhoodriver #columbiarivergorge #active #strong #motivation #determination #lifestyle #getfit #fatloss #fatfighters7 #boxing
