Components of fitness
The ability to produce maximal force as quickly as possible in a contraction.
What is power?
The Illinois run
What test do we use for agility?
Increased heart rate, increased stroke volume and increased blood pressure
What are three short-term responses of the circulatory system to physical activity?
A system that kicks in during high-intensity efforts lasting up to 2 minutes and leads to lactate buildup.
What is the lactic acid system?
To increase the heart rate and blood flow to muscles.
What are the goals of a warm up?
The ability of a muscle or group of muscles to exert a force repeatedly over an extended period of time.
Sit ups, push ups, pull ups
How do you test muscular endurance?
The amount of blood the heart pumps with each beat increases to eject more blood.
What happens to the stroke volume during physical activity?
Carbohydrates (glucose), fats and sometimes proteins are the main energy fuel sources.
What are the main fuel sources used in the aerobic energy system?
Aerobic activity phase, stretching phase and specific activity phase
What are the three phases of a warm up?
What is balance?
1RM Bench Press, Grip Strength Test (dynamometer)
It increases immediately during exercise to pump more blood and oxygen to the muscles.
What happens to the heart rate during physical activity?
An energy system that requires oxygen and supports endurance activities like long-distance running.
What is the aerobic system?
Reduce muscle stiffness, decrease heart rate and decrease temperature.
What is the purpose of a cool down?
The ability of a muscle to produce force against a resistance.
What is muscular strength?
Fitness tests include standing long jump, vertical jump
How do we test power?
The amount of air inhaled and exhaled during normal respiration, it increases during physical activity.
A molecule that is the immediate energy currency used during all physical activity.
What is ATP (Adenosine Triphosphate)?
A low intensity exercise (that allows your pulse rate to slow down)
What is the most effective way of cooling down?
The ability to change direction quickly and accurately.
What is agility?
Stork test
How do you test balance?
A measure of maximum oxygen uptake
What is VO2 max?
The high-energy compound donates a phosphate group to ADP to rapidly regenerate ATP during short bursts of intense activity
What is the role of CP in energy production?
To supply oxygen and nutrients for energy production and remove metabolic byproducts such as heat
Why do we need increased blood flow to muscles?
