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
