Quantitative Research Critique: Exercise Programs
Introduction
The article “Exercise training program based on minimum weekly frequencies: effects on blood pressure and physical fitness in elderly hypertensive patients”, written by Wilson M. De Moraes, Pamella R. M. Souza, Monica H.N.P. Pinheiro, Maria C. Irigoyen, Alessandra Medeiros, and Marcia K. Koike is a quasi-experimental non-controlled study. The study’s aim was to see how a twice-weekly exercise program, sometimes referenced as low frequency exercise program, affected elderly hypertensive patients. Previous studies have been done on exercise programs but have not been researched enough to determine how often they should be completed per week. By using several different

The independent variable in the study is the twice- weekly exercise-training program that is being tested on the patients. The dependent variables in the study are BP, physical fitness, and functional ability of the elderly hypertensive patients. Sociodemographic variables in the study were pharmacologic treatment, educational level, and income. The extraneous variables in this study are participant complete less than 80% of the exercise sessions, involved in another exercise program, cannot understand the instructions due to cognitive problems, chest pains, dizziness or discomfort, unmanageable hypertension that is greater than 160/100 mmHg, and any bone, muscle, joint or other previous problems that could affect participation in the program( De Moraes et al., 2012). The confounding variables in the study are peripheral blood glucose, BP at rest, and BMI. The hypotheses and variables are all clearly stated in the study.
Problem and Purpose
The research problem in this study is how often exercise programs need to be implemented, predominantly in hypertensive elderly patients, to their affect BP, physical fitness, and functional ability. The author of the study describes how important it is for elderly adults with arterial hypertension to adhere to the proper exercise programs to help reduce the longing effects of this disease. The author discusses that increased amounts of exercise are shown to decrease the adherence to the program in elderly
