Respostas agudas imediatas e tardias da flexibilidade na extensão do ombro em relação ao número de séries e duração do alongamento

Abstract

The objective of this study was to investigate the relation between the number of series and duration of shoulder stretching exercises on the immediate and late acute effects on flexibility. Seventy individuals with ages ranging from 20 and 30 years with no previous flexibility training participated in this study. Randomly, 10 subjects composed the control group (CG) and the others were equally divided into three groups according to the duration of the stimulus, namely: 10 seconds (G10), 60 seconds (G60) and 120 seconds (G120). Later, each group was subdivided in relation to the number of series, namely: one (G10A, G60A, G120A) and three series (G10B, G60B, G120B). Flexibility was measured through an universal goniometer and the observations occurred shortly after, 90 minutes after and 24 hours after stimulation. The analysis of variance ANOVA identified significant association between the time of stimulus and the other variables (p = 0.042). No differences of flexibility were verified between experimental groups, but all groups exhibited values higher than CG. The temporal comparison of absolute values of flexibility for groups submitted to the same stimulus duration and number of series revealed significant differences only for G120A, G60B and G120B, between the first observation and 24 hours after. On the other hand, the analysis of the percentile values showed that the stimulation time and the number of series were associated with the duration of the flexibility acute increment. In this case, no differences between groups were verified, except between G60A and G60B in the observation after 24 hours. One concludes that stimulus duration may provide higher initial flexibility, regardless the number of series. However, the immediate gains of flexibility could not be maintained after 24 hours. No one knows, however, if progressive long-duration stimuli would provide long-term higher amplitude if compared with stretching exercises performed in shorter periods of time.

Assessment of proprioceptive exercises in the treatment of rotator cuff disorders in nursing professionals: a randomized controlled clinical trial

“…All exercises were selected in accordance with various studies that assessed shoulder rehabilitation in patients with rotator cuff disorders [14][15][16][17][18][19] . Both rehabilitation programs consisted of pendulum exercises of the shoulder, stretching of the cervical spine and shoulder muscles, exercises with a stick (to maintain or improve range of motion), exercises to strengthen the muscles of the rotator cuff and scapular stabilizers [14][15][16][17][18][19][20] . Only in Group 2, proprioceptive exercises were conducted.…”

Remobilização por alongamento estático cíclico em músculo sóleo de ratos imobilizados em encurtamento

“…O alongamento, realizado na prática fisioterapêutica, tem o intuito de manter uma relação ótima de comprimento-tensão dos músculos, e desta forma, atuar no aumento das amplitudes de movimento (ADMs) perdidas, ou evitar a sua diminuição, que muitas vezes é conseqüência da imobilização (16)(17)(18) . Dessa forma o presente trabalho justifica-se na tentativa de esclarecer alguns fenômenos morfológicos que ocorrem durante o uso de técnicas de alongamentos, como método de remobilização em músculos previamente encurtados pela imobilização.…”

Efeito de agentes térmicos aplicados previamente a um programa de alongamentos na flexibilidade dos músculos isquiotibiais encurtados

“…Entretanto, deve-se destacar que os resultados de um programa de alongamentos na flexibilidade sofrem a influência do tipo de alongamento, do número de séries, da duração de cada alongamento no ponto de desconforto e do momento da avaliação (24) , os quais não são objeto de discussão neste artigo.…”
