What condition would benefit from increased bone density associated with regular physical activity?
Osteoporosis
Osteoporosis is a health condition that weakens bones
How many vertebrae form the lumbar spine?
5 Lumbar (low back) - the main function of the lumbar spine is to bear the weight of the body.
What role does the stomach play in digestion?
Breaks down food by releasing enzymes
The stomach is a hollow organ, or “container,” that holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a usable form.
what type of activity are individuals with an ectomorphic body type well-suited to?
Long distance running
Ectomorphs are long and lean, with little body fat, and little muscle.
What is a long-term benefit of regular strength training?
Increased size of fast twitch muscle fibres
“Twitch” refers to the contraction, or how quickly and often the muscle moves.
What is the role of adenosine triphosphate?
Broken down to create energy for the body Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level.
Which component of fitness is defined as ‘full potential joint range of motion’?
Flexibility
Which energy system uses fat and carbohydrate as fuel in the presence of oxygen?
Aerobic
Aerobic System – This system uses carbohydrates (glucose/glycogen) and fats to replenish ATP
What is the name of the connective tissue surrounding the whole muscle?
Epimysium - a sheath of fibrous elastic tissue surrounding a muscle.
Which muscle is the prime mover during horizontal flexion of the shoulder?
Pectoralis major
Which blood vessels carry blood under low-moderate pressure?
The veins
Veins are blood vessels that carry blood towards the heart.
Which joint action occurs when the spine bends sideways?
Lateral flexion
Movement of a body part to the side is called lateral flexion. This type of movement is commonly associated with the neck and spine.
What is the name of the air sacs in the lungs where gaseous exchange occurs?
Alveoli
The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
What joint action occurs when the quadriceps contract eccentrically?
Knee flexion
Flexion – bending a joint. This occurs when the angle of a joint decreases. For example, the elbow flexes when performing a biceps curl. The knee flexes in preparation for kicking a ball. Extension – straightening a joint.
What activity would mesomorphs be most likely to excel at?
Gymnastics
Which muscle is located at the anterior upper arm?
Biceps
What is a long-term respiratory adaptation to low-moderate cardiovascular training?
Increased aerobic capacity
Which of the following is a function of the heart?
Pump nutrients and oxygen to the body tissues.
It’s the muscle at the centre of your circulation system, pumping blood around your body as your heart beats. This blood sends oxygen and nutrients to all parts of your body, and carries away unwanted carbon dioxide and waste products.
What is the function of the lungs?
To remove carbon dioxide from the body.
The lungs absorb oxygen from the air you breathe in and transfer it into your bloodstream so that it can get to every part of your body. As the cells in your body work, they produce a waste gas called carbon dioxide that is released into the bloodstream. Your lungs get rid of this waste gas when you breathe out.
What is a characteristic of involuntary muscle?
It is smooth
Involuntary muscles include smooth muscles and cardiac muscles.
Involuntary muscles are the ones that do not move or contract under the conscious control of a person, i.e., these muscles work automatically.
