4.1 - Intro
What is the term to describe the product of chemical reactions to produce movement?
Energy
What are the three main types of nutrients found in food ?
Carbohydrates, Proteins, Fats
What is the ATP-PC system
Suitable for high intensity activities that have a short duration like a 50m sprint
What is lactic acid?
A by-product of anaerobic glycolysis that is created when glucose is partially broken down to provide energy for ATP resynthesis
Define Vo2 Max
a measure of an individual's maximum oxygen consumption during intense physical activity.
The term used to describe the body's ability to participate in physical activity
Fitness
What is the products of the chemical reaction that breaks down carbohydrates?
Glucose
What is the Lactic acid system ?
Suitable for high intensity activities that have a short to medium duration like a 400m
What is lactate?
a component of lactic acid that remains after hydrogen ions (i.e. the acidic component of lactic acid) are separated
Define 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)
The term to describe activities completed by an athlete to improve fitness in their chosen sport?
Training
What is the product of the chemical reaction that takes place to break down proteins?
Amino Acids
What is aerobic system?
Suitable for lower intensity activities that have a long duration like a 15km run
Identify the fitness components.
Speed, Power, Strength, aerobic capacity, agility, muscular endurance, flexibility
How do you calculate your lactate threshold?
85 % of maximum heart rate
The study of Energy, Fitness and Training
Exercise Physiology
What is the product of the chemical reaction that takes place to break down fats?
Fatty Acids
What is glycolysis?
The process of breaking down glycogen in order to resynthesise ATP
Define Aerobic Capacity and training methods to improve this component.
Aerobic capacity is the ability of the heart, lungs and circulatory system to supply oxygen and nutrients efficiently to working muscles and remove waste products.
Continuous, Interval, Fartlek
Identify 3 acute physiological adaptations.
Increased HR, respiratory rate, muscular temperature, muscle fibre recruitment.
A plan developed to improve the performance of an athlete to achieve their goals
Training strategies.
What is the chemical energy that is produced from nutrients processed by the body ?
Adenosine Triphosphate (ATP)
What is anaerobic glycolysis?
The process of breaking down glycogen without oxygen present via the lactic acid system
Define Power
Power is the ability to exert maximum force in the shortest amount of time. Power is the product of strength and speed.
Define chronic physiological adaptations and provide an example
Chronic physiological adaptations are longer-term changes in body systems and organs that take place with training over time.
Improve ability to deliver oxygen around the body
