Exercise Physiology

Which of these is a immediate effect of physical exercise?

• Increased Breathing Rate

• Lower resting Heart Rate

• Lower Breathing Rate

• Bigger and stronger Muscles

Muscular fatigue is caused by a build up of?

• Energy

• Glucose

• Lactic acid

• Oxygen

During exercise, your breathing rate increased in order to accommodate:

• Increased carbon dioxide needs of your muscles

• Increased oxygen needs of your stomach

• Increased oxygen needs of your muscles

• Increased carbon dioxide needs of your stomach

Which process helps remove excess heat from your body?

• Shivering

• Sweating

• Increased energy use

• Producing lactic acid

Our breathing rate increases and you start to breathe heavily, this happens because

• More blood gets circulated around the body

• We have started to perform a physical activity

• To break down Lactic Acid and replenish energy supplies.

• Our muscles need more oxygen so you breathe deeper and quicker so a supply of oxygen can get to the muscles.

Selective Redistribution of Blood occurs when:

• To prevent the overheating of muscle tissue

• Because of the increased need for oxygen and removal of Carbon Dioxide

• Arteries dilate or constrict selectively to direct blood flow from non working muscles

• Cardiac Output increases

The body's main source of energy

• Protein

• Vitamins

• minerals

• Carbohydrates

Anaerobic exercises require ______ whereas aerobic exercises require ______.

• No energy, energy

• Energy, no energy

• Oxygen, no oxygen

• No oxygen, oxygen

ATP stands for what?

• Aerobic Tri-potassium

• Adenosine Tri-phosphate

• Adrenaline Twitch Protein

• Anaerobic Triple Phosphate

Which of these defines the word 'predominantly'?

• Taking place by itself / independently

• Done or existing alone

• Present as the strongest or main element

• More important than anything else
