Soc19 Short Term Effects Of Exercise

Question 1

What are the Short Term Effects on Musculo-skeletal System

Answer 1

Muscle Fatigue- Muscles feel tired

Lactic Acid/Lactic Accumulation-Lactic Acid gathers in the muscles due more work and lack of oxygen

Increased Oxygen Debt-Lack of oxygen in the muscles which lead to lactic acid

Increased Muscle Temperature-
respiration tales more frequently releasing heat

Redistribution of blood flow- vascular shunting to areas of active muscles as they need an increased oxygen demand for energy
Cramps

Question 2

What are the Short Term Effects on the Cardio-Respiratory System

Answer 2

Increased Heart Rate- When exercising the body needs to pump more blood around your body to get to your working muscles

Increased Breathing Rate and Depth of Breathing- Tidal volume and Minute volume increases to allow more oxygen to be inhaled and excess carbon dioxide exhaled

Increased Stroke Volume- This is the amount of blood ejected by the heart each beat .When exercise begins this will increase in order to increase blood flow to the muscles

Question 3

Muscle fatigue: when muscles get tired.

Question 4

Lactate accumulation: when lactic acid gather in the muscles/ blood due to increased work intensity.

Question 5

Heart rate: a number of times the heart beats per minute.

Question 6

BPM: beats per minute.

Question 7

Stroke volume: the amount of blood pumped by the heart during each beat.

Question 8

Cardiac output: the amount of blood ejected from your heart in one minute. CO = stroke volume (SV) x heart rate (HR)

Question 9

Oxygen debt: The amount of oxygen needed at the end of physical activity to break down any lactic acid.

Question 10

Minute Volume

Answer 10

The amount of air that is breathed in and out of the lungs in one minute
Minute Volume = Tidal Volume × Breathing Rate
