The influence of resistance exercise with emphasis on specific contractions (concentric vs. eccentric) on muscle strength and post-exercise autonomic modulation: a randomized clinical trial

Contextualização:Ações concêntricas apresentam maior estresse cardiovascular quando comparadas às excêntricas. Entretanto, não se sabe a influência desses tipos de ações no comportamento da modulação autonômica cardíaca durante o processo de recuperação pós-esforço.Objetivo:Comparar o efeito de um treinamento resistido para o grupo extensor do joelho realizado com ênfase concêntrica vs excêntrica sobre a força muscular e a recuperação pós-exercício considerando índices de variabilidade de frequência cardíaca (VFC) em jovens saudáveis.Método:Cento e cinco homens, com idades entre 18 e 30 anos, foram randomizados em quatro grupos: controle concêntrico (CCONC), controle excêntrico (CEXC), treinamento concêntrico (TCONC) e treinamento excêntrico (TEXC). Os grupos CCONC e CEXC realizaram uma sessão de exercício reduzido (ER) para o grupo extensor do joelho [três séries de uma repetição a 100% de uma repetição máxima (1RM)], e os grupos TCONC e TEXC realizaram dez sessões de treinamento. A VFC foi analisada no momento basal e na recuperação após as sessões (T1, T2, T3 e T4).Resultados:Observou-se aumento da força muscular para o grupo TEXC. Em relação à modulação autonômica cardíaca, observou-se, em comparação ao momento basal, aumento dos índices SDNN e SD2 no momento T1 nos grupos CCONC e CEXC e aumento dos índices RMSSD, SD1 e AF (ms2) nos momentos T1, T2 e T4 no grupo TEXC.Conclusões:Conclui-se que o treinamento resistido realizado com ênfase em contrações excêntricas promoveu ganho de força e aumento da modulação vagal cardíaca durante o processo de recuperação em relação à condição basal.

Influência de calços na orientação postural de indivíduos com escoliose idiopática

INTRODUCTION: The relationship between the orientation of the segments and the adjustments that can be triggered by shoe lift and insoles in scoliotic patients during maintenance of standing position is unclear. OBJECTIVE: To verify static changes and those associated with unilateral manipulations of shoe lift in the postural orientation in people with idiopathic scoliosis. MATERIALS AND METHODS: Experimental group composed of ten patients with idiopathic scoliosis with double curve (less 10°) and control group with ten participants without scoliosis (aging from 13 to 24 years). Participants were videotaped in upright stance, standing with no, low (1 cm), and high (3 cm) shoe lift, which were placed under right and left shoe. In each condition, the participant maintain upright stance for 15 seconds and reflective markers were affixed on specific anatomical places. Postural angles were obtained: high thoracic; medium thoracic; thoracolumbar; and lumbar, as well segmental angles: shoulder; scapula; pelvis; and knee. RESULTS: In the no shoe lift condition, differences were observed between groups for high and medium thoracic angles and for shoulder. With low and high shoe lift under the right foot, difference was observed between shoe lift heights for high thoracic, for pelvis and knee angles. With low and high shoe lift under the left foot, differences between groups were observed for thoracolumbar angle and between shoe lift heights for pelvis and knee angles. CONCLUSIONS: The shoe lift promotes reorientation in the lower regions of the spine and segments of pelvis and knee. It might be suggested that in the scoliosis with double curves, manipulation in the basis of support changes the alignment of the trunk that might promote structural reorganization and the search of new adjustments among segments in individuals with idiopathic scoliosis.

Pelvic floor muscle strength evaluation in different body positions in nulliparous healthy women and its correlation with sexual activity

Objective: The aim of this study was to assess pelvic floor muscle (PFM) strength in different body positions in nulliparous healthy women and its correlation with sexual activity.Materials and Methods: Fifty healthy nulliparous women with mean age of 23 years were prospectively studied. Subjective evaluation of PFM was assessed by transvaginal digital palpation (TDP) of anterior and posterior areas regarding the vaginal introitus. A perineometer with inflatable vaginal probe was used to assess the PFM strength in four different positions: supine with extended lower limbs (P1); bent-knee supine (P2); sitting (P3); standing (P4).Results: Physical activity, 3 times per week, was reported by 58% of volunteers. Sexual activity was observed in 80% of women and 82% of them presented orgasm. The average body mass index (BMI) was 21.76 kg/m(2), considered as normal according World Health Organization (WHO). We observed that 68% of volunteers were conscious about the PFM contraction. TDP showed concordance of 76% when anterior and posterior areas were compared (p = 0.00014). There was not correlation between PFM strength and orgasm in subjective evaluation. The PFM strength was significantly higher in standing position when compared with the other positions (p < 0.000). No statistical difference was observed between orgasm and PFM strength when objective evaluations were performed.Conclusions: There was concordance between anterior and posterior areas in 76% of cases when subjective PFM strength was assessed. In objective evaluation, higher PFM strength was observed when volunteers were standing. No statistical correlation was observed between PFM strength and orgasm in nulliparous healthy women.

Leg Amputation for an Extensive, Severe and Intractable Sickle Cell Anemia Ulcer in a Brazilian Patient

A 35-year-old African Brazilian patient had sickle cell anemia complicated with recurrent vasoocclusive (VOC) crises and refractory painful leg ulcers for 16 years. The ulcers started over both medial malleoli and expanded gradually. The ulcer on the left leg spread from the foot to the knee circumferentially and was refractory to all forms of therapy within the frame work of multi-disciplinary care. The patient agreed to a below the knee amputation of the left leg. He felt much better after the amputation but developed severe neuropathic phantom pain that was well controlled medically. He could differentiate the sickle cell anemia and ulcer pain from the neuropathic pain. About 6 months after the amputation he had dengue fever with fatal outcome. This is the first report of treatment of refractory sickle cell anemia leg ulcer with amputation and probably the first report of a Brazilian patient with sickle cell anemia and dengue fever.

Influence of the resistance training on heart rate variability, functional capacity and muscle strength in the chronic obstructive pulmonary disease

Background. The chronic obstructive pulmonary disease (COPD) is associated with the strength and resistance decreasing in addition to the dysfunction on autonomic nervous system (ANS). The aerobic training isolated or in association with the resistance training showed evidence of beneficial effects on an autonomic modulation of COPD; however, there are no studies addressing the effect of isolated resistance training.Aims. This study aims at investigating the influence of resistance training on an autonomic modulation through heart rate variability (HRV), functional capacity and muscle strength in individuals with COPD.Design. Clinical series study.Setting. Outpatients.Population. The study involved 13 individuals with COPD.Methods. The experimental protocol was composed by an initial and final evaluation that consisted in autonomic evaluations (HRV), cardiopulmonary functional capacity evaluation (6-minute walk test) and strength evaluation (dynamometry) in addition by the resistance training performed by 24 sessions lasted 60 minutes each one and on a frequency of three times a week. The intensity was determined initially with 60% of one maximum repetition and was progressively increased in each five sessions until 80%.Results. The HRV temporal and spectral indexes analysis demonstrates improvement of autonomic modulation, with significant statistical increases to sympathetic and parasympathetic components of ANS representing by SDNN, LF and HF. In addition, it was observed significant statistical increases to shoulder abduction and. knee flexion strength and functional capacity.Conclusion. The exclusive resistance training performed was able to positively influence the autonomic modulation; in addition it promoted benefits on cardiorespiratory functional capacity and strength benefits in individuals with COPD.Clinical Rehabilitation Impact. This study could contribute to clinical and professionals researchers that act with COPD, even though the resistance component of pulmonary rehabilitation presents consensual benefits on several healthy indicators parameters. There is no evidence about the effects on HRV before. Moreover, this study showed, on clinical practice, the HRV uses as an ANS activity on sinus node evaluation and highlights further importance on scientific context.
