EFEITOS DO TREINAMENTO RESISTIDO TIPO EXPLOSIVO DINÂMICO NA RIGIDEZ ARTERIAL E PARÂMETROS HEMODINÂMICOS EM IDOSOS

Abstract

Studies have investigated the effects of resistance and power training using elastic bands on health parameters in older adults. However, little is known about how power exercises relate to arterial stiffness in this population. The present study aimed to investigate the effects of dynamic explosive resistance training with elastic bands on arterial stiffness and hemodynamic parameters in older adults. This study follows an experimental design, employing a pre- and post-intervention assessment. The sample consisted of 26 sedentary older adults, randomly assigned to the Intervention Group (IG = 12) and the Control Group (CG = 14). Assessments and training sessions were conducted at the gym and dance studio of Ceuma University – São Luís, MA. All participants underwent evaluations of pulse wave velocity, pulse pressure, central pulse pressure (arterial stiffness), systolic blood pressure, diastolic blood pressure, central systolic blood pressure, and central diastolic blood pressure before and after 12 weeks of training. The exercise protocol was performed twice a week, totaling 24 sessions. The program consisted of six resistance exercises, alternating with squats, with no rest intervals between sets and exercises. The CG did not participate in any supervised exercise program during the 12-week period. Comparing pre- and postintervention time points, significant improvements were observed in pulse wave velocity, pulse pressure (arterial stiffness), and systolic blood pressure after the 12- week intervention (p < 0.05). In conclusion, 12 weeks of dynamic explosive resistance training with elastic bands reduced arterial stiffness and significantly improved systolic blood pressure in older adults.
