Advanced resistance training review Flashcards
Resistance training adaptations are specific to (6):
- Muscle action (eccentric vs concentric vs isometric)
- Velocity (fast or slow)
- Repetition Range (strength vs endurance vs hypertrophy vs power)
- Range of motion (full or partial)
- Degree of stability (stable or unstable)
- Force vector (horizontal vs vertical)
What is the block to all other qualities?
Endurance
What are the 3 mechanisms of training for hypertrophy?
- Mechanical overload
- Muscle damage
- Metabolic stress
Explain the 3 mechanisms of training for hypertrophy
mechanical overload
- heavier loads, increased time under tension (TUT)
muscle damage
- eccentric actions, moderate loads, moderate reps
metabolic stress
- “the pump”, +30 s of total stress
What is the evidence in favor of exercise induced muscle damage (EIMD)?
- exercise at long muscle lengths lead to greater EIMD and hypertrophy when compared to short muscle lengths
- eccentric actions lead to greater hypertrophy and EIMD
What is the evidence that does NOT favor exercise induced muscle damage (EIMD)?
- similar hypertrophy between untrained and trained groups, despite differences in EIMD
- extend of muscle damage does not relate to MPS or hypertrophy. too much damage is DETRIMENTAL
- many forms of exercise lead to EIMD but not hypertrophy
What is the evidence in favor of metabolic stress?
- blood flow occlusion in immobilized patients reduces the amount of atrophy (14-17%)
- significant increased in muscle hypertrophy when BFR is combined with mechanical load
What is the evidence that does NOT favor of metabolic stress?
- extent to which it induces hypertrophy without mechanical stimuli is small
- exercise that leads to high levels of metabolic stress could be detrimental to muscle hypertrophy
What is the evidence in favor of mechanical overload?
- remove mechanical load (immobilization) -> muscle atrophy
- greater protein synthesis following heavier resistance training
What is the evidence that does NOT favor of mechanical overload?
- high degrees of muscle tension have been associated with mainly neural gains
- overload does not need to be excessive
- bed rest patients can minimize atrophy with blood flow occlusion
Why is strength important?
- enhances force-time characteristics
- improved sport skill performance (jumping, sprinting, COD)
- improved specific sport skill performance
- decrease injury rates
What is power?
work/time
(force x distance) / time
force x velocity
