Question | Answer |
---|---|
glycolysis is | breakdown of carbs to produce ATP |
this energy system is used in sprinting and resistance training | phosphagen |
Name the 3 energy systems that replenish ATP | phosphagen/ATP-PC |
glycolytic | |
oxidative | cardiac output= up |
lactic acid results from activation of: | fast glycolysis |
this system is used in low intensity acivities of long duration | oxidative/aerobic |
the involvement of each energy system in production depends on: | intensity of muscular activity |
duration | |
name the amount of intensity required to work each energy system | phosphagen 90-100% |
fast gylolysis 75-90% | |
fast gycolysis/oxidative 30-75% | heart rate, |
oxidative 20-35% | |
name the work to rest ratios for each energy system | phosphagen 1:12 to 1:20 |
fast glycolysis 1:3 to 1:5 | no |
fast glycolysis/oxidative 1:3 to 1:4 | no change |
oxidative 1:1 to 1:3 | amount of blood from heart in 1 beat |
what system has highest rate of energy production | phosphagen |
What enzyme catalyzes the rate limiting step of glycolysis | PFK |
name amount of time to train each energy system | phosphagen 5-10 sec |
glycolysis 15-30 sec | increases rapidly, then more gradually, then plateaus |
glycolysis w/ oxidative 1-3 min | |
oxidative >3 min |
