What is ATP? ATP (Adenosine Tri Phosphate) is a chemical produced in the body, responsible for producing energy for muscle contraction When ATP is broken down, energy is released The nutrients we extract from food (carbohydrates, proteins, fats) are used to produce ATP ATP (Adenosine Tri Phosphate) is a chemical produced in the body, responsible for producing energy for muscle contraction When ATP is broken down, energy is released The nutrients we extract from food (carbohydrates, proteins, fats) are used to produce ATP

In the body there are three main pathways for the breakdown of ATP to make energy. These systems are dependent on the type of activity being performed. The three pathways are: - ATP-CP - Anaerobic (lactic acid) - Aerobic In the body there are three main pathways for the breakdown of ATP to make energy. These systems are dependent on the type of activity being performed. The three pathways are: - ATP-CP - Anaerobic (lactic acid) - Aerobic

ATP-CP System ATP (chemical produced in the body that helps deliver energy CP (creatine phosphate – a naturally produced chemical stored in the muscles) Energy for immediate activity Uses the ATP already stored in the muscle cells Main source of energy for short, explosive bursts (0-10 secs) CP stores replace themselves after approx 2 mins rest ATP (chemical produced in the body that helps deliver energy CP (creatine phosphate – a naturally produced chemical stored in the muscles) Energy for immediate activity Uses the ATP already stored in the muscle cells Main source of energy for short, explosive bursts (0-10 secs) CP stores replace themselves after approx 2 mins rest

Lactic Acid System The breakdown of glycogen in the absence of oxygen for energy Main source of energy is glycogen (found in carbohydates) Energy for short-term high-intensity exercise Because this system does not require oxygen to burn carbohydrates, significant amounts of lactic acid can build up The breakdown of glycogen in the absence of oxygen for energy Main source of energy is glycogen (found in carbohydates) Energy for short-term high-intensity exercise Because this system does not require oxygen to burn carbohydrates, significant amounts of lactic acid can build up

Lactic acid causes muscle soreness and fatigue (the next day it can be muscle stiffness) When the heart and lungs cannot deliver enough oxygen to the muscles to produce energy aerobically, the body switches to anaerobic production Lactic acid causes muscle soreness and fatigue (the next day it can be muscle stiffness) When the heart and lungs cannot deliver enough oxygen to the muscles to produce energy aerobically, the body switches to anaerobic production

Aerobic System The breakdown of glycogen in the presence of oxygen for energy Long-term, low-intensity activity Main source of energy is carbohydrates, fats Because this system requires oxygen to burn the carbohydrates and fats, lactic acid does not build up (but can do, when anaerobic system is suddenly required again, eg sprint, when heart and lungs are unable to supply enough oxygen to meet energy demands) The breakdown of glycogen in the presence of oxygen for energy Long-term, low-intensity activity Main source of energy is carbohydrates, fats Because this system requires oxygen to burn the carbohydrates and fats, lactic acid does not build up (but can do, when anaerobic system is suddenly required again, eg sprint, when heart and lungs are unable to supply enough oxygen to meet energy demands)

Energy systems involved in basketball The major system used in a game of basketball is the anaerobic lactic acid system, meaning the activity is at a shorter duration, but at a higher intensity. The energy is supplied through the burning of carbohydrates, which builds up lactic acid, which eventually causes performance to decrease. The major system used in a game of basketball is the anaerobic lactic acid system, meaning the activity is at a shorter duration, but at a higher intensity. The energy is supplied through the burning of carbohydrates, which builds up lactic acid, which eventually causes performance to decrease.

The aerobic system allows you to play for a long period of time, running up and down the court. Anaerobic lactic acid system affects the way you play the game as in basketball you repeat multiple high intensity activities with minimal rest period of short quick bursts of runs and jumps, followed by sprints to the other end of the court. Although rests are present, stretches of continuous play can last anywhere from 2 to 3 minutes. The aerobic system allows you to play for a long period of time, running up and down the court.
