Short-term Effects On The Muscular System Flashcards
What is one short-term effect of exercise on muscles?
Muscles release extra energy for movement and generate heat
This heat can make you feel hot during exercise.
What substance do muscles produce during anaerobic activity?
Lactic acid
Lactic acid is produced when muscles exercise without sufficient oxygen.
What happens if lactic acid builds up in the muscles?
It leads to muscle pain and fatigue
Muscle fatigue requires oxygen to remove lactic acid and recover.
What is oxygen debt?
The amount of oxygen needed to remove lactic acid and recover
Oxygen debt occurs after intense anaerobic exercise.
What must you do to repay oxygen debt?
Slow down or stop the activity
This can negatively impact performance.
What is the effect of exercise on the depth and rate of breathing?
Both increase
This helps meet the increased oxygen demand in muscles.
What does increased tidal volume refer to?
Increased depth of breathing
It allows more oxygen to be taken in during exercise.
What is produced during aerobic respiration that needs to be expelled?
Carbon dioxide
Increased breathing helps eliminate this excess carbon dioxide.
How does exercise intensity affect breathing rate and depth?
They become more extreme with intense exercise
You breathe deeper and quicker during hard exercise.
What happens to breathing rate after anaerobic activity?
It remains higher than normal until oxygen debt is paid off
This ensures enough oxygen is taken in post-exercise.
True or False: Brain fatigue is a short-term effect of physical exercise.
True
Cognitive fatigue can occur during intense physical activities.
