A Quantataive Critique

The purpose of the research study is to determine the effects of cardiac rehabilitation and exercise training in obese coronary patients.

2. Are the problem & purpose of the study clearly & concisely expressed?

Yes, the studies purpose or objective as the article calls it is the first statement made in the abstract.

3. Does the purpose identify the variables, population, & setting of the study?

The purpose statement does identify the population as obese coronary patients; the setting is two large teaching institutions and the variables are obese coronary patients versus non-obese coronary patients involved in cardiac rehabilitation and exercise training.

4. What is the significance of the problem for generating nursing knowledge as identified by the investigator?

It was determined cardiac rehabilitation significantly reduced coronary risk factors in obese patients. It was also determined that coronary risk factors were even further reduced in non-obese patients following cardiac rehabilitation. The point made was that by specifically targeting obese coronary patients for cardiac rehabilitation, would yield greater exer

. . .
What are the strengths and weaknesses of the study?

The strength is the previous studies that assisted to form a baseline of data. Give you rational for classification. Although the most commonly used sampling, caution should be exercised in analyzing and interpreting the data. What recommendations are made for future research?

These data indicate that obese patients with CHD need to be specifically targeted with more vigorous obesity intervention and exercise training in order to further improve CHD risk factors and further reduce subsequent CHD events. What descriptive statistics are given for the study variables?

Table A Obese subjects (mean)

BMI 31. The control group was the non-obese group that participated. The research question and the literature review are assumed from the purpose. There is limited data available on the effects of vigorous risk factor intervention in obese patients with known CHD. The dependant variable is conceptually defined as “Modest reductions in BMI, obesity, and severe obesity occur after cardiac rehabilitation.

This study is a quasi-experimental research design, because there is manipulation of the variable by studying the effects of cardiac rehabilitation and exercise training in obese coronary patients. In addition, obese patients demonstrate significant improvements in most coronary risk factors after rehabilitation, although improvements in exercise capacity are greater in non-obese patients. 8 kg/m2 for men and more than equals 27. What descriptive statistics are reported for the sample?

The results are expressed as mean plus minus 1 SD.
