ABSTRACT

This study aimed to analyze both influence of aerobic fitness and active recovery in heart rate (HR) reduction after maximum exercise (i.e. maximum incremental test) in untrained young women. Seventeen women were evaluated (23.88 ± 4.85 years), divided by the medium of peak of consumption of oxygen (30.80 mL. kg-1.min-1), in higher or lower aerobic fitness obtained during a maximum incremental test performed on a cycle ergometer. The post-exercise recovery was performed actively and passively, on two randomly non-consecutive days. It was noticed that HR at 6th and from the 6th to 10th min after the passive and active recovery, respectively, was lower in the higher aerobic fitness group, beyond that, the values of %HR reduction from the 6th to 10th min at 6th min after passive and active recovery, respectively, were higher in the higher aerobic fitness group. After active recovery, HR in 8th and 9th min and %HR reduction of the 8th to 10th min were lower and higher, respectively (p<0.05) than passive recovery in the lower aerobic fitness group. In short, the aerobic fitness influenced HR reduction after maximum exercise in untrained young women, mainly, after passive recovery. Besides that, the active recovery showed benefits in HR reduction in lower aerobic fitness group....(AU)


O presente estudo teve como objetivo analisar a influência da aptidão aeróbia e recuperação ativa na redução da frequência cardíaca (FC) após o exercício máximo (teste incremental máximo) em mulheres jovens não treinadas. Foram avaliadas dezessete mulheres jovens (23,88 ± 4,85 anos), divididas pela mediana do consumo pico de oxigênio (30,80 mL∙kg-1 ∙min-1 ), em maior ou menor aptidão aeróbia obtida durante um teste incremental máximo. A recuperação pós-exercício foi realizada de forma ativa e passiva, em dois dias experimentais randomizados e não consecutivos. Foi observado que, a FC foi menor no grupo de maior aptidão aeróbia no 6º min após a recuperação passiva e do 6º ao 10º min após a recuperação ativa, além disso, os valores do percentual de redução da FC foram maiores no grupo de maior aptidão aeróbia do 6º ao 10º min e no 6º min após a recuperação passiva e ativa, respectivamente. Após a recuperação ativa, a FC no 8º e 9º min e o percentual de redução da FC do 8º ao 10º min foram menores e maiores, respectivamente (p <0,05) do que após a recuperação passiva no grupo com menor aptidão aeróbia. Em suma, a aptidão aeróbia influenciou na redução da FC pós-exercício máximo em mulheres jovens não treinadas, principalmente após a recuperação passiva. Além disso, a recuperação ativa auxiliou na redução da FC no grupo com menor aptidão aeróbia....(AU)

ABSTRACT

This study aimed to assess the blood pressure (BP), cardiac autonomic modulation at rest, in physical exercise and in the recovery in untrained eutrophic (E) and overweight (O) youth. The body mass index (BMI), waist circumference (WC), systolic BP-SBP (E: 109.80 ± 10.05; O: 121.85 ± 6.98 mmHg) and diastolic BP - DBP (E: 65.90 ± 7.28; O: 73.14 ± 12.22 mmHg) were higher in overweight and the heart rate recovery (%HRR) was lower as compared with E volunteers. The BMI was associated with SBP (r= 0.54), DBP (r= 0.65), load on the heart rate variability threshold - HRVT (r= -0.46), %HRR 2' (r= -0.48) and %HRR 5' (r= -0.48), and WC was associated with SBP (r= 0.54), DBP (r= 0.64) and HRR 2' (r= -0.49). The %HRR was associated to SBP, DBP and HRVT. In summary, the anthropometric variables, BP and cardiac autonomic modulation in the recovery are altered in overweight youth.
