Rоbert is а 55-yeаr-оld mаle with stable angina. During his graded exercise test, he develоps angina symptoms at a heart rate of 130 bpm and a blood pressure of 160 mmHg, with RPP = 20,800. He is on a beta-blocker and sublingual nitroglycerin PRN. He has no prior MI or revascularization. His physician has cleared him for supervised exercise.Using ACSM guidelines, build an exercise prescription for Robert. Include aerobic and resistance training FITT components. Also answer:1. Robert’s anginal threshold occurs at an HR of 130 bpm. What should his target heart rate ceiling be during aerobic exercise, and why?2. Under what circumstances should Robert use prophylactic nitroglycerin before exercise, and what side effect must be monitored after administration?3. What absolute test termination criteria applied during Robert’s GXT, and which criterion should be watched most closely during exercise sessions?

Based on discussions you have had with friends who have complained about how long they waited for a callback, you dispute the researcher’s claim. You decide to test your hypothesis. Over the course of a few weekends, you record the wait time for 50 randomly selected patients. The average wait time for these 50 patients is 17 minutes with a standard deviation of 5 minutes. Do you have enough evidence to support your hypothesis that the average call back wait time exceeds 15 minutes? Test at a = 5%.
