Do continuous and intermittent exercises sets induce similar cardiovascular responses in the elderly women?

Abstract

There is a lack of information about elderly acute cardiovascular responses in the elderly during exercise involving different muscle groups and strategies of load/repetition interaction (LRI) in continuous and intermittent sets. The purpose of this study was to compare heart rate (HR), systolic blood pressure (SBP), rate-pressure product (RPP) and quality of exercise performance (QEx) of upper and lower body exercises (arms abduction and hip flexion) in different situations of LRI. Twelve healthy women aged 65 to 85 years old volunteered to this study. The subjects performed both exercises at 12 maximal repetitions workload, continuously (2 sets of 12 reps) and alternately (4 sets of 6 reps). HR was measured with a cardiotachometer and SBP through auscultation technique at the end of the last repetition of each set. The exercises were recorded in video to evaluate QEx. At least for the selected exercises, LRI did not influence QEx. However, SBP and RPP values for the intermittent sets were significantly higher than for continuous situations (p < 0.05). The authors concluded that continuous sets seem to be associated to greater cardiovascular stress in elder subjects, mainly because of SBP responses during the exercise

Série fracionada da extensão de joelho proporciona maiores respostas cardiovasculares que séries contínuas

“…This procedure was used in three studies [11][12][13] and the results indicated a decrease in the cardiovascular responses. However, some methodological differences were identified that could discharacterize the strength training program, such as a discontinuous series characterized by the inclusion of another exercise 11 ; a too-long interval (15 seconds) and measurement of heart rate, only, which is limited to infer on the cardiovascular demand during the strength training 12 and interval occurring at each repetition 13 .…”

Ajustes agudos, subagudos e crônicos da pressão arterial ao exercício resistido

“…Segundo os autores, isso pode ser atribuído ao fato de o exercício ter tido dois momentos de início de movimento (retirada da inércia), comprometendo, assim, a utilização da energia elástica muscular e, consequentemente, promovendo uma maior sobrecarga. Já Veloso et al 11 observaram maiores respostas pressóricas durante o exercício realizado de forma contínua. De acordo com Polito et al 10 , diferenças metodológicas podem ter interferido nos resultados, acarretando em respostas distintas.…”
