Effects of Different Dispositions of Resistance Exercises on Subjective Perception of Effort, Discomfort and Affectivity in Older Women

Abstract

The purpose of the study was to verify the effect of two dispositions of resistance exercises on rate of perceived of effort (RPE), discomfort and affectivity in older women. Twenty older women (68.0±6.6 years, 69.8±12.7 kg, and 155.9±7.0 cm) performed in a balanced and randomized design two experimental conditions, namely: a circuit (CIRC) fashion and another in a traditional (TRAD) fashion. In both conditions, six resistance exercises in the following order were performed: push press with kettlebell, swing with kettlebell, plantar flexion, squatting, ladder displacement and shoulder flexion with naval rope, with the same load and three sets of 15 repetitions/exercise. In the CIRC condition, the exercises were performed in stations, with no interval among them, and at the end of the last exercise, a three-minute interval was performed. For the TRAD condition the exercises were performed in consecutive sets, with intervals of 90s between the sets and the exercises. After 15 min of the closure of each session, the RPE (OMNI), feeling (Hardy and Rejeski) and a discomfort scale were applied. There was no significant difference (P>0.05) among the sessions for PSE (TRAD = 6.0±1.2 vs. CIRC = 6.1±0.9), feeling (TRAD = 3.7±1.6 vs. CIRC = 3.6±1.2) and discomfort (TRAD = 5.2±1.4 vs. CIRC = 5.1±1.3). The results suggest that PSE, discomfort and affective response to resistance exercises are similar when performed in CIRC or TRAD in older women. Keywords: Exercise. Aging. Physical exertion. ResumoO objetivo do estudo foi verificar o efeito de duas diferentes disposições de execução de exercícios resistidos sobre a percepção subjetiva de esforço (PSE), o desconforto e a afetividade em mulheres idosas. Vinte mulheres idosas (68,0±6,6 anos, 69,8±12,7 kg e 155,9±7,0 cm) foram distribuídas de forma balanceada e aleatorizada para duas condições experimentais: disposição de circuito (CIRC) e disposição tradicional (TRAD). Em ambas as condições, seis exercícios resistidos foram executados na seguinte ordem: push press com kettlebell, swing com kettlebell, flexão plantar, agachamento, deslocamento em escada e flexão de ombros com corda naval, com mesma carga e três séries de 15 repetições/exercício. Na condição CIRC os exercícios foram executados em forma de estações, sem intervalo entre os exercícios e, ao final de cada série foi concedido intervalo de três minutos. Para condição TRAD os exercícios foram executados em séries consecutivas, com intervalos de 90s entre os exercícios e as séries. Após 15 min do termino de cada sessão foram aplicadas as escalas de PSE (OMNI), sentimento (Hardy e Rejeski) e desconforto. Não ocorreram diferenças significativas (P>0,05) entre as sessões para PSE (TRAD = 6,0±1,2 vs CIRC = 6,1±0,9), sentimento (TRAD = 3,7±1,6 vs CIRC = 3,6±1,2) e desconforto (TRAD = 5,2±1,4 vs CIRC = 5,1±1,3). Os resultados sugerem que a PSE, o desconforto e a resposta afetiva aos exercícios resistidos são semelhantes quando realizados em CIRC ou TRAD em mulheres idosas. Palavras-chave: Exercício Físico.

Autonomic response of older women to the submaximal effort in the six-minute walk test: a cross-sectional study

“…When we evaluated perceived exertion using the Borg scale, the sample reported mild tiredness. Ribeiro et al 22 and Alves et al 23 evaluated women and they reported the same perceived exertion during a walking circuit-based exercise and resistance exercises, considering them easy.…”
