Efeitos agudos e reprodutibilidade de sessões de exercício resistido em circuito sobre o custo energético, apetite e a ingestão alimentar em pacientes com sequelas de acidente vascular cerebral

Abstract

Stroke is a cerebrovascular disease with high worldwide prevalence, mainly due to the worsening of risk factors in the population, such as arterial hypertension, diabetes, obesity, and sedentary lifestyle. In the context of post-stroke rehabilitation, resistance training has been highlighted in the main position stands for professional practice due to neuromuscular stimuli characteristic of this modality. It is known that after an exercise bout the responses associated to the metabolism, appetite and energy intake may remain altered during the first 24-h of recovery. However, acute effects of circuit resistance training (CRT) sessions on these variables in stroke survivors, as well as the reproducibility of these responses, remain totally unknown. The aim of this Master's Dissertation was to evaluate the acute effects and reproducibility of CRT sessions on appetite and food intake in hemiparetic individuals due to stroke sequelae. Seven (7) participants met the eligibility criteria and, in randomized order, participated in a control session (CTL) and two sessions of CRT. The CRT involved 10 exercises with 3 sets of 15 maximum repetitions, 45-second intervals of walking between sets. Exhaled gases were collected 10 minutes before, during, and 40 minutes after CTL and CRT bout to calculate exercise energy cost and relative energy intake after CTL/CRT. Significant differences between CTL and CRT were observed only in the first 9 h of the post-exercise period for hunger, fullness, and desire to eat (P < 0.05). Compared to CTL, hunger (∆ -11.3 end -10.7 mm, respectively), desire to eat (∆ -21.4 and -19.5 mm, respectively), and relative energy intake (∆ -552 and -592 kJ, respectively) were significantly lower after 1st and 2nd bouts of CTR (P ≤ 0.05), while the perception of fullness was significantly higher (∆ 14.5 and 16.6 mm, respectively) (P < 0.001). No significant differences in appetite or relative energy intake were observed between the two CRT bouts. A bout of CRT decreased post-exercise appetite and energy intake in chronic hemiparetic stroke patients. Decreased appetite perceptions lasted for around 9 h and were reproducible
