Anaerobic resistance training Flashcards
nervous system benefits from resistance training
improved recruitment, synchronicity, firing rate and responsiveness
muscle benefits from resistance training
fat free mass
improved tissue quality
hypertrophy
connective tissue and bone benefits from resistance training
improved tissue quality
increased strength and mass
increased BMD
cardiovascular benefits from resistance training
increased capillary density
increased stroke volume
increased metabolic efficiency
enhanced vascular health
metabolic system benefits from resistance training
improved cell efficiency
mitochondria proliferation
enhanced by-product management
endocrine system benefits from resistance training
reduced catabolic activity
increased anabolic affinity (hormones & receptors)
improved insulin sensitivity
greatest effects on body composition (3)
aerobic exercise
resistance training
diet/nutrition
def: running economy
VO2 and a-VO2 at steady state submaximal running
Respiratory exchange ratio (RER)
difference between oxygen consumed and CO2 produced
used to estimate respiratory quotient at submaximal intensities
Respiratory quotient (RQ)
Difference between CO2 produced and Oxygen consumed. measured at site of tissue
Used to identify relative oxidation contribution of fat, carbohydrate and protein
goal oriented adaptation categories of resistance training
function or physical readiness anaerobic endurance Hypertrophy strength power
Resistance training emphasis on Function or general physical readiness
prepares body for more challenging stress
usually body weight used for load
Resistance training emphasis on anaerobic endurance
increasing TUT
increases musculo-metabolic efficiency
improves endurance
Resistance training emphasis on Hypertrophy
increasing protein synthesis
enhancing fiber recruitment
reduced role nervous system
exchanges maximal speed or force for stress on metabolic system
Resistance training emphasis on strength
centers upon motor unit recruitment, with factors such as force-couple efficiency, reduced restriction, and maximal joint stability
Resistance training emphasis on power
ballistic or plyometric exercise with a goal of fast-twitch fiber recruitment and nervous system proficiency
% of 1RM represented by amount of reps (12)
1=100%
2=95%
% reduces by 2.5% each increase in reps starting with 3 being 92.5% and 12 being 70%
general fitness training guidelines
intensity-50-70% energy-glycolytic frequency-3-5x/week volume-30-36 sets/day reps-8-20 rest-30-60 sec mode-multiple body weight movements endocrine-limited GH, testosterone, adrenal hormones
