Cardiovascular Response to Exercise: Static and Dynamic
Karten in diesem Stapel (7)
- 1define static and dynamic exercisestatic: muscle contraction generating force with no change in muscle length
dynamic: muscle contraction generating force to shorten a muscle reducing length and joint angle - 2relationship between systolic, MAP and diastolic in incremental-large increase in systolic due to inotropic effect on HR
-decreased disatolic slightly due to reductions in TPR (increased vasodilation
-overall MAP unchanged (reduction in TPR) - 3TPR and dynamic exercise-TPR sees sharp linear decline with exercise intensity due to vasodilation to perfuse tissues increasing blood flow
- 4how training status modifies response to incremental exercise test-untrained more likely to get CI (unable to reach 85% of max HR) at high intensity due to lower SV
- higher SV in trained means decreased workload on heart so reduced resting and max HR
- heart rate increases in untrained due to lower SV (HR must compensate to maintain Q) - 5static exercise effect on BP, CO, HR-overall MAP hardly changes
-ionotropic effects on heart icnrease systolic BP
-diastolic may fall slightly due to lower TPR
-slight fall in SV - 6MSNA changes in static-increased MSNA in static compresses veins decreasing downstream perfusion to tissues
-results in huge reactive hyperaemia when released to increase flow - 7how high BP can go in weightlifting480/350mmHg
