Name That Energy System
What are the three energy systems in order of usage?
ATP-PC system, Glycolysis, Cellular respiration
What type of training/workouts would you recommend to an athlete that is wanting to work the atp-pc system?
Short sprints, plyometrics, explosive movements, and high intensity resistance training
This byproduct of anaerobic glycolysis can cause muscle fatigue and a burning sensation.
lactic acid
What are the three macronutrients we use for fuel?
Carbohydrates, protients, fats
What are the three muscle fiber types?
Type I, Type IIA, Type IIX,
This system produces lactic acid as a byproduct and dominates during 400m sprints.
anaerobic glycolysis system
What metabolic pathway would be primarily activated for a power lifter? Why.
ATP-PC, no oxygen required, 2 ATP, not long-lasting
The molecule known as the “energy currency” of the body.
ATP
What are the two different types of fats? Name an example for each.
Saturated Fat- butter, fatty meats, cheeses
Unsaturated Fat- olive oil, avocado, fish, nuts
Which muscle fiber type is light in colour?
Type II x/b/ Type II A
This system provides energy for activities lasting 0–10 seconds and does not require oxygen.
ATP-PC
Which energy system has a spike of ATP but depletes quickly?
ATP-PC
What muscle fiber type would be used in a marathon runner?
Type I or slow-oxidative (SO)
Which macronutrient plays an important role in providing energy in a powerlifting exercise?
Carbohydrates
Olympic sprinters, for example, may possess as much as 70-80 percent fast-twitch muscle fibres.
True
This system is dominant during long-duration activities.
aerobic system
What are some training considerations to keep in mind (consider intensity, duration, and recovery) for a triathalon runner?
Training for this system should be low to moderate intensity (40-70% intensity) and have a long timeframe
The energy system that uses phosphocreatine for rapid ATP regeneration.
ATP-PC system
Which Macronutrients plays an important role in endurance running? Name them in order of importance.
carbohydrates, protein, fats
Most of the ATP that is generated from Cellular Respiration occurs in which sub-pathway?
Electron Transport Chain (ETC)
What are the aerobic energy systems in order?
Glycolysis, Krebs Cycle, Electron transport Chain
What are some training considerations to keep in mind for a hockey player (consider intensity, duration, and recovery)
Training for this system should be fairly powerful (70-95% intensity) and a longer timeframe than immediate alactic training
Approximately how much ATP is generated after glycolysis, krebs cycle, and ETC?
36-38 ATP
Fats should comprise __________ % of total energy intake for four- to 18-year-olds
25% to 35%
Type 1 Slow Oxidative muscle fibres are high in....
High in myoglobin and have high fatigue resistance
