Term 1 Flashcards
What does ATP-PC stand for?
Adenosine Tri-Phosphate Phosphocreatine
What is glycogen?
Readily available source of energy stored in the liver for fast acting energy.
How long does recovery for ATP take?
2 minutes 100%, 30 seconds 50%
Source of energy for lactic system?
Carbohydrates are the only source of fuel.
Laxative energy duration?
30 secs and 3 minutes for medium to high intensity
Why do we feel fatigue?
Lactic acids builds up in the muscle causing a burning sensation. Becomes a by-product in our muscles.
Examples of lactic?
400m sprint, 100m freestyle
Fuel for aerobic energy system?
Utilises fats, carbohydrates, oxygen and proteins for resynthesising ATP for energy use
Examples aerobic?
Cycling, jogging, walking
Duration of aerobic system?
Endless until exhaustion
Def aerobic capacity?
Ability to persist in physical activities that rely heavily on oxygen for energy production
Def muscular endurance
Ability of muscles to perform repetitive work over a prolonged period of time
Def speed
The rate of travel of a body without regard to direction
Strength
The capacity to apply force against a resistance
Power
Ability to use strength in rapid, explosive muscle contractions
Flexibility
Range of motion of a body’s joints
Agility
Ability to change the position of the body quickly and precisely and still retain balance
Which components of fitness relate to muscular strength and ability?
Strength, endurance and power
Which components of fitness relate to physical dexterity?
Flexibility, agility and speed
Fitness requirements for physical activity?
Respiratory, circulatory and muscular systems
What is VO2 max?
Measure of an individual’s maximum oxygen consumption during intense physical activity
What influences it?
Age, physical ability (genetics), sex, level of physical fitness
What is lactate threshold?
The point at which lactic acid (I.e. lactate and hydrogen ions) begins to accumulate in the muscles at a faster rate than it can be removed (in the blood)
What are the muscles fibres?
Slow-twitch and fast-twitch
What are the types of flexibility?
Static/passive and dynamic
Circuit training?
Improves agility as it allows you to do different exercises in your session
Plyometric training?
Is about using explosive power to create movement. This can help improve agility
Interval training?
Best training to improve speed- specific to what you’re doing and has work to rest ratio which allows to resynthesises atp to practice again
Individuality
Acknowledges that each athlete is different, and so training should consider their specific traits
Specificity
A successful training program will bring about adaptations (changes or improvements) that suit the physical activity being targeted
