What is the impact of exercise on the respiratory system in the short term?
Increased breathing rate and depth.
Fill in the blank: The immediate increase in heart rate during exercise is known as ______.
cardiac response.
What is one effect of exercise on the skin?
Increased blood flow leading to sweating.
Multiple choice: Which of the following is a short term effect of exercise? A) Increased muscle strength B) Improved flexibility C) Increased heart rate
C) Increased heart rate.
Short answer: How does exercise influence blood pressure temporarily?
Blood pressure increases during exercise.
True or False: The short term effects of exercise are the same for everyone.
False.
What is the short term effect of exercise on metabolic rate?
Metabolic rate increases.
Fill in the blank: The feeling of euphoria after exercise is often referred to as a ______.
runner’s high.
What physiological change occurs in muscles during exercise?
Increased blood flow and nutrient delivery.
Multiple choice: Which factor can affect the short term effects of exercise? A) Fitness level B) Time of day C) Type of exercise D) All of the above
D) All of the above.
Short answer: Name a potential negative short term effect of exercise.
Injury or muscle strain.
True or False: Increased sweating is a short term effect of exercise.
True.
What is the role of endorphins released during exercise?
To reduce pain and enhance mood.
Fill in the blank: The immediate recovery phase after exercise is known as ______.
cool down.
What happens to glycogen stores during short term exercise?
Glycogen stores are depleted.
Multiple choice: Which system is primarily responsible for energy production during short, high-intensity exercise? A) Aerobic system B) Anaerobic system C) Endocrine system
B) Anaerobic system.
Short answer: How does exercise affect hydration levels in the body?
Exercise leads to increased fluid loss through sweating.
True or False: Short term effects of exercise can vary based on environmental conditions.
True.
What is the effect of exercise on sleep patterns in the short term?
Improved sleep quality.
Fill in the blank: Short term effects of exercise can lead to ______ in athletic performance.
enhancements.
What is one cardiovascular adaptation that occurs during exercise?
Increased heart efficiency.
Muscle fatigue
when muscles get tired
Lactate accumulation
when lactic acid gather in the muscles/ blood due to increased work intensity
BPM
beats per minute
Stroke volume
the amount of blood pumped by the heart during each beat.
Cardiac output
the amount of blood ejected from your heart in one minute
Cardiac output formula
CO= Stroke Volume (SV) x heart rate (HR)
Oxygen debt
The amount of oxygen needed at the end of physical activity to break down any lactic acid
Effects on the muscles
muscle fatigue, lactic accumulation & cramp.
Effects on the respiratory system
increased need for oxygen/ removal of CO2.
Increased rate and depth of breathing
Effects on the heart
increased HR, stroke volume and cardiac output.
Athletes who are fitter have
a lower RHR and quicker recovery rate.
When you exercise hard, you use up more oxygen than you take in. This shortfall creates
Oxygen debt
