Ejercicio físico en pacientes con diabetes e hipertensión: prevalencia de respondedores y no respondedores para mejorar factores de riesgo cardiometabólicos / Effects of a six weeks exercise training program for type 2 diabetes mellitus and hypertensive patients

Background: There is a wide interindividual variability in the response to a period of exercise training. The science have reported that a minimum of participants could be non-responders for improving different health-related outcomes after training. Aim: To compare the effects of a 6-weeks exercise program on body composition, cardiovascular and metabolic outcomes patients with type 2 diabetes and hypertension. Material and Methods: Data from 23 trained subjects were used in a secondary analysis of the response to exercise. Of these, 14 were considered adherent to training and nine as non-adherent. Body mass, height, waist circumference, four skinfolds and their sum, blood pressure and plasma triglyceride levels were assessed before and after the training period. Results: Among adherent participants, significant reductions were observed in the sum of four skinfolds (30 ± 7 to 27 ± 6 mm, p ≤ 0.05), systolic blood pressure (133 ± 18 to 127 ± 20 mmHg; p ≤ 0.05) and plasma triglycerides (125 ± 58 to 102 ± 34 mg/dL; p ≤ 0.05). No changes were observed in weight or diastolic blood pressure. Among non-adherent participants, no changes of measured parameters were observed. Among adherent participants, 57% were considered as non-responders for waist circumference, 7% for the sum of skinfold thickness, 50% for systolic blood pressure, 64% for diastolic blood pressure and 57% for plasma triglycerides. Conclusions: Participants with a good adherence to a 6-weeks exercise training program experienced overall improvement in body composition, blood pressure and plasma triglycerides. The prevalence of non-responders varied considerably among measured outcomes.

Interacción entre farmacoterapia hipotensiva y terapia con ejercicio físico requiere regulación farmacológica en pacientes hipertensos / Interaction between antihypertensive therapy and exercise training therapy requires drug regulation in hypertensive patients

Background: Exercise training could interact with the pharmacological therapy of hypertension, increasing the effects of these medications. Aim: To assess the effects of 12 weeks of physical training on blood pressure of hypertensive or diabetic patients, already receiving pharmacological therapy. Material and methods: Twelve participants with diabetes and hypertension, 16 participants with hypertension and 18 healthy participants were studied. During six weeks no intervention was carried out, except the treatment for their underlying conditions. During the ensuing six weeks, participants were subjected 12 sessions of physical training. Blood pressure was measured at baseline and after six and twelve weeks of intervention. Results: During the period without physical training, no changes in blood pressure were observed. After the physical training intervention systolic blood pressure decreased by 16, 17 and 20 mm Hg in participants with diabetes and hypertension, participants with hypertension and healthy participants, respectively. Diastolic blood pressure decreased by 9 and 6 mmHg in participants with diabetes and hypertension and hypertension alone, respectively. Conclusions: There is a decrease in blood pressure among hypertensive participants receiving pharmacological therapy, after a period of physical training.
