Which of the following is not increased during isometric exercise?
Net fall in total peripheral resistance due to vasodilation in exercising musclesWith the sta of an isometric muscle contraction, the hea rate rises, probably as a result of psychic stimuli acting on the medulla oblongataWithin a few seconds of the onset of an isometric muscle contraction, systolic and diastolic blood pressures rise sharply.The response to exercise involving isotonic muscle contraction is similar in that there is a prompt increase in hea rate, but different in that a marked increase in stroke volume occursIncreased O2 consumption result in increase of respiratory rateRef: Ganong&;s review of medical physiology 23rd edition pg no: 518
