Sports with modified rules can be a useful in the sessions of cardiac rehabilitation (CR). But, as a difference with callisthenic exercises and aerobic work, adherence was pour.
The aim of this study was to determinate predictors of non adherence to sports with modified rules (MRS). We made a cross sectional study in a group of 140 patients (pts) of a community base CR (Social Club) program. Patients play 30 minutes of MRS in each 90 minutes CR session. Program includes 3 times a week sessions. MRS included were: Swimming, Volley, Football and Tennis.
Results:
Mean age was 62.82 +/- 10, (92.9% males) and mean body mass index (BMI) was 23.69 +/- 3.35 kg/m2. Secondary prevention (history of coronary by pass surgery: 25%, myocardial infarction: 47.1%, coronary angioplasty: 31.4% or stable chronic angina: 22.1%) was the main indications for CR in 85.7% pts, the others were on primary prevention (multiple cardiovascular risk factors). We observed the following rate of cardiovascular risk factors (CRF): 72.1% dyslipidaemias (DL), 62.9% hypertension (HTN), 10.7% diabetics (DB) and 8.6% current smokers. Adherence to sports was 71.4%. At the moment of this study, 70.7% of pts were on CR treatment for >= 1 year.
Univariate analysis showed that age, female sex, wearing glasses, no treatment with beta blockers, stroke, other neurological illness, arthrosis, and low exercise capacity (<=5 MET) were predictors of non adherence to MRS, all with P < 0.001. Left ventricular dysfunction, symptomatic or silent myocardial ischemia, and the BMI failed to predict non adherence. The only predictor of non adherence in the multivariate logistic regression analysis was the age, OR 1.12 IC 95% 1.04 to 1.20 P < 0.001. Male sex was excluded to the model because it predicts the fail perfectly.
Conclusions:
Age, that conditioned all the others variables, was the principal predictor of non adherence for MRS. In the future we should developed modified sports suitable for all ages.
