SOC 19 Short Term Effects Of Excersise Flashcards
What is muscle fatigue?
Muscle fatigue is when you exercise, your muscles can feel weak, painful, and tired.
What causes muscle fatigue?
Lactic acid
What happens when there is no oxygen available for respiration?
We produce lactic acid, a process known as lactate accumulation.
What are cramps in relation to muscle fatigue?
Cramps are a severe sort of muscle fatigue, causing the muscles to contract in a painful way.
What happens to your heart rate during exercise?
Your heart beats faster during exercise, which increases your heart rate.
What is heart rate?
Heart rate is the number of times your heart beats per minute.
How does the resting heart rate of a trained athlete compare to an untrained person?
A trained athlete is likely to have a lower resting heart rate than someone who is untrained.
What is a characteristic of a trained athlete’s recovery after exercise?
A trained athlete is more likely to have a quicker recovery rate after exercise.
What is stroke volume?
Stroke volume is the amount of blood pumped by the heart during each beat.
How does physical activity affect stroke volume?
Stroke volume increases during physical activity as the muscles require more blood.
What happens to the heart with regular training?
With regular training, the heart increases in size, thickness, and strength, leading to an increase in stroke volume.
What is the effect of increased stroke volume on heart rate?
As stroke volume increases, the heart rate decreases, enabling athletes to perform at a high intensity.
What is cardiac output?
Cardiac output is the amount of blood pumped by the heart in one minute.
How is cardiac output calculated?
Cardiac output = stroke volume x heart rate.
What is the relationship between cardiac output and physical performance?
The higher your cardiac output, the better your physical performance.
