Long term effects of exercise- cardio-respiratory

Question 1

what physiological adaptations occur in the cardio-respiratory system, after 12 weeks

Answer 1

increased capillarisation in the blood
improved strength of the diaphragm and intercostal muscles
increased untilisation of the alveoli (reduces breathing frequency)
increased tidal volume and minute ventilation

Question 2

what do the adaptations to the cardio-respiratory system mean

Answer 2

the adaptations mean that more oxygen can be consumed and transported from the alveoli into the capillaries and into the red blood cells

Question 3

what adaptations occur in the cardiovascular system

Answer 3

reduced systolic phase
increased cardiac output
increased BP when exercising
decreased BP when resting
reduced resting HR
increased number of red blood cells (and haemoglobin)

Question 4

what are the improvements to sporting performance

Answer 4

working anaerobically for longer (reducing OBLA)
reducing glycogen and PC stores
reduced recovery time
faster lactic acid removal
myoglobin stores resaturated at a faster rate (due to increased oxygen uptake)
