pe energy system

• energy

  • required for any muscular activity to take place
• energy

  • cellular activity comes from atp
• food

  • serves as the fuel of our body
• adenosine triposphate

  • molecule that serves as a usable form of energy
• adenosine triphosphate

  • major fuel source for the body
• adenosine triphosphate

  • our body stores energy in this form
• 3 different systems

  1. phosphagen system
  2. anaerobic glycolysis system
  3. aerobic energy system
• phosphagen system

  • explosive exercises lasting 8-10 seconds
• phosphagen system

  • inefficient energy system
• phosphagen system

  • generates atp quickly, but limited supply
• phosphagen system

  • ex : lifting, throwing, walking
• glycolysis

  • pathway that splits carbohydrates
• anaerobic lactic system

  • medium to high intensity burts of activity, 10 secs to 2 mins
• anaerobic glycolysis system

  • ex : basketball, volleyball
• aerobic energy system

  • oxidative system
• aerobic energy system

  • most efficient energy sytem
• aerobic energy system

  • slowest
• aerobic energy system

  • needs presence of oxygen
• aerobic energy system

  • used for long distance events kr exercises for 5 mins
• aerobic energy system

  • ex : cycling, rowing, marathon
• physical activity

  • any movement of the body that requires energy and expenditures
• physical fitness

  • ability to carry out tasks without undue fatigue
• maximum oxygen consumption or VO2

  • ability to consume oxygen for maximal work output over periods lasting greater than one minute
• aerobic exercise

  • moderate intensity
  • repetitive movements
• anaerobic exercise

  • high intensity workout
• anaerobic exercise

  • means "without air"
• phases of exercises

  1. warm up
  2. training exercise proper stretching
  3. cooldown
• warm up

  • period or act of preparation
• training exercise

  • simulation of an activity for the purpose of learning how to perform that activity
• stretching

  • straighten or extend one's body or a part of one's body
• carbohydrates, protein, fat

  to ➡️

  glucose, amino acids, fatty acids

  equals 🟰

  adenosine triposphate
• atp pc

  • adenosine triphosphate phospo creatine
• atp cp

  • adenosine triphosphate creatine phosphate
