| Annotation | The main intention of this study was to determine whether the American College of Sports Medicine (ACSM) standards by which exercise intensity is prescribed is applicable to an older population. Because maximal heart rate (HR) and maximal aerobic power (VO2max) decline with age, it is possible that they are not. The 112 older women in this study (aged 60 to 72) exercised at four intensities requiring an average of 55 to 91% of VO2max. Exercise bouts were within the expected ranges based on ACSM guidelines. HR values as a percentage of HR reserve were much lower than expected based on the guidelines. Ratings of perceived exertion (RPE) values were lower than expected at a given percentage of VO2max, and plasma lactate levels were also relatively low, suggesting that older women are able to exercise at a higher percentage of VO2max than levels currently recommended. Results indicate that HR expressed as a percentage of maximal HR is an appropriate method of prescribing exercise intensity in healthy, sedentary 60- to 72-year old women. The HR reserve method is not recommended in this population, because it is likely to result in the exercise being performed at a higher than expected percentage of VO2max. (RH). |
