Effects Of Exercise

Question 1

Short Term-Muscles

Answer 1

1) Increase in muscle temp.
2) Increased muscle fatigue (lactic acid)
3) Vascular Shunt

Question 2

Short Term- Cardiovascular System

Answer 2

1) Increase in Heart Rate
2) Increase in Stroke Volume
3) Increase in Cardiac Output

Question 3

Short Term- Respiratory

Answer 3

1) Increase in respiratory rate
2) Increase in minute ventilation
3) Increase in tidal volume
4) Increase in depth and frequency of breathing

Question 4

Long Term-Muscles

Answer 4

-Hypertrophy of Muscle (repeated damage +repair of muscle fibres)
-Muscular Endurance (slow-twitch fibres increase in size by 20%)
-Resistance to Fatigue (increased O2 capacity)

Question 5

Long Term -Other

Answer 5

-Increased bone density (reduced risk of osteoporosis)
-Hypertrophy of Heart (increase in size, increase in contraction strength)

Question 6

Long Term- Respiratory System

Answer 6

1) Capilierisation (increase in density +efficient O2 uptake)
2) Slight increase in TV + Vital Capacity (more air inspiration)
3) Increase in Minute Volume
4) Greater Intercostal Muscle Strength (lower resting respiratory rate)
5) Exchange of Gases at Alveoli is more efficient
