Question

For each case study, you must develop an appropriate exercise prescription.  Use the FITT recommendations from the ACSM guidelines. You will need to calculate a workload for the particular type of mode of cardiovascular exercise you choose utilizing the metabolic equations. Once you pick an appropriate intensity, use the VO2R equation to calculate the oxygen consumption. Then use that to solve for the workload on the treadmill or cycle, whichever you think is best. Don't forget to indicate frequency and duration as well.  Please note any special considerations or precautions for each of them.

John, a 32 year old executive, is a type II diabetic with a fasting glucose level of 140 mg/dL. John currently weighs 220 pounds. He wants to begin an exercise program and has hired you as his trainer. Prior to developing diabetes John was somewhat active. He walked regularly and enjoyed gardening. His doctor informed him that he needs to participate in cardiovascular activity along with changing his diet in order to reduce his blood sugar. There are times when experience hypoglycemia and is concerned about exercising because of this issue. As a complication of diabetes, John has been experiencing neuropathy in both feet. He was given a GXT and his VO2max was estimated at 40ml/kg/mn.

Based on this information, design an ExRx using VO2R method to choose an appropriate intensity range and include: FREQUENCY, TIME, and TYPE OF EXERCISE. Bases on this VO2R range, use the metabolic equations to help determine the workload. Follow ACSM guidelines for special populations for this ExRx.

this is all the information I got

Answer 1

There is little data to examine the compatibility of these approaches to monitoring exercise intensity in people with type 2 diabetes. Symptoms associated with diabetes (ie pain, peripheral neuropathy, etc.) influence subjective experience of exercise. For example, women with type 2 diabetes reported greater effort at a reduced workload compared to those without type 2 diabetes. Additionally, autonomic neuropathy, so prevalent in this population, may affect performance. . Maximum heart rate, affecting% HRR and the compatibility between these measurements and the RPE.

VO2 and heart rate (HR) are used extensively to determine the appropriate training intensity for clinical, health and athletic groups. It has been demonstrated that if% reserve (% R) is used, instead of% max, HR and VO2 can be used interchangeably to accurately characterize exercise intensity. Thus, the heart rate reserve (HRR) can be determined if the VO2 reserve (VO2R) is known. Therefore, the aim of this study was to compare VO2 R and HRR during a moderate intensity exercise (50% R). Physically active students underwent maximum treadmill testing to exhaustion. During which VO2 and HR were monitored to determine the maximum. At the end of the peak test, calculations were made to determine the percentile score that approximately 50% of the VO2R subjects should give. The subjects then returned to complete the test below the maximum (50% R) after at least two days. % VO2R and% HRR were calculated and compared with the expected value as well as with each other. Statistical analysis showed that VO2 at 50% R was significantly higher than the actual achieved VO2, p <0.001. On the contrary, the expected mean RH at 50% R was significantly lower than the actual achieved RH, p <0.001. In conclusion, this study indicated that VO2 could be predicted more accurately than heart rate during moderate-intensity exercise. The low correlation between VO2R and HRR indicates that care should be taken when relying on human resources to determine VO2.
