ABSTRACT
The purpose of this study was to compare the effects of myofascial release and muscle energy on acute outcomes in trunk extensors active range-of-motion and strength in recreationally resistance-trained women. Seventeen apparently healthy women performed three experimental protocols using a cross-over, randomized (counterbalanced in Latin Square format), and within-subjects design: a) range-of-motion and strength test after a manual myofascial release protocol (MFR); b) flexibility and strength test after a muscle energy protocol (ME); and c) range-of-motion and strength test without myofascial release or muscle energy (control condition). Active trunk range-of-motion was measured via a sit-and-reach test and trunk extension strength via isometric dorsal dynamometer. A significant increase in range-of-motion was found for MFR (p = 0.002; d = 0.71) and ME (p < 0.001; d = 0.47) when comparing post-intervention with baseline values. Similarly, a significant increase for strength was found for MFR (p = 0.018; d = 0.10) when comparing post-intervention with baseline values. In conclusion, both techniques (MFR and ME) improved trunk range-of-motion with the sit and reach test immediately post-intervention; however, MFR showed greater magnitude increases in range-of-motion (MFR: (medium magnitude) vs ME: small magnitude). Due to the potential health implications, both (MFR and ME) responses should be among the many considerations for rehabilitation and performance exercise prescription when prescribing an exercise regimen.

With aging comes a reduction in neuromuscular and neuromotor function. Different strategies have been used to mitigate these functional losses. Certain manual therapy techniques and interventions have been explored with regard to their ability to improve functional capability and balance in an older adult population. The purpose of this study was to analyze the acute effects of two massage techniques on functional capability and balance performance in recreationally trained older adult women. Twenty-eight older adult women (66.74 ± 4.61 years) completed three interventions: a) stick massage followed by functional capability and balance performance tests (MMS), b) manual massage followed by functional capability and balance performance tests (MM), c) no MMS or MM (control condition (CC)) - only performed the functional capability and balance performance tests. Functional capability was assessed by four tests that are part of the Senior Fitness Test: the 6-min walk (W6), the chair sit-and-reach (CSR), the 8-foot up-and-go (8FUG), and the 30s-chair stand (30s-CS). Balance was assessed using the Berg Balance Scale (BBS). Significant differences (p < 0.001) were observed between MM and MMS compared to CC among 30s-CS, W6, CSR, and 8FUG. BBS showed a significant difference between MM and CC (p = 0.041). Both MM and MMS demonstrated significant acute improvements in the functional capability of recreationally trained elderly women and may be included in an exercise program.

Fundamentos: A prática de exercícios físicos é indicada como atividade complementar no tratamento de doenças como hipertensão arterial e doenças cardiovasculares. Objetivo: Verificar o comportamento da pressão arterial (PA) após quatro meses de treinamento em indivíduos hipertensos medicados. Métodos: Quarenta indivíduos sedentários ou inativos há pelo menos um ano foram estratificados em dois grupos: Grupo-treinamento (GT) (96,7±8,3kg; 25,2±5,3%G; 0,96±0,05RC/Q; 31,4±4,5ml.kg.m-1; 32±3,7kg.m-2) e Grupo-controle (GC) (97,1±8,6kg; 26,2±5,8%G; 0,98±0,08RC/Q; 33,3±6,8ml.kg.m-1; 32±3,5kg.m-2). Todos os sujeitos passaram por uma avaliação clínica e física; o GT realizou três sessões semanais em dias alternados, totalizando 48 sessões, com duração média de 60 minutos diários, executando simultaneamente o treinamento aeróbio, de força e flexibilidade, realizado no Espaço Bem-Estar (EBE) no CENPES/Petrobrás. A PA foi aferida em repouso por meio auscultatório pré e pós-treinamento e os dados foram tratados pela ANOVA two-way com a utilização do post hoc de Scheffé, quando necessário, para a comparação intra e intergrupos. Resultados: O GT demonstrou uma redução de 9% na PA sistólica (PAS) (p<0,05) e de 2,2% na PA diastólica (PAD) (p>0,05) na análise intragrupo. Intergrupos, o GT apresentou diferenças significativas em relação ao GC na PAS, mas não na PAD. Em todas as outras mensurações realizadas também foram encontradas diferenças significativas do GT em relação à situação de prétreinamento (84,1±6,5kg; 19,1±3,5%G; 0,92±0,07RC/Q; 38,3±5,9ml.kg.m-1; 27,1±2,8kg.m-2) e em comparação ao GC (98,6±10,2kg; 26,4±4,2%G; 0,98±0,06RC/Q; 32,2±8,1ml.kg.m-1; 32,1±2,2kg.m-2) após o treinamento físico. Conclusão: O programa EBE do CENPES/Petrobrás realizado durante quatro meses promoveu a redução da PA após um programa de exercícios em hipertensos medicados.
Background: Physical exercise is recommended as a supplementary activity for treating diseases such as arterial hypertension and cardiovascular diseases. Objective: To ascertain blood pressure (BP) behavior in medicated hypertensive individuals after four months training at a Company Fitness Center in Rio de Janeiro, Brazil. Methods: Having been sedentary or inactive for at least a year, forty individuals were stratified into two groups: the Training Group (TG) (96.7±8.3kg; 25.2±5.3%BF; 0.96±0.05RC/Q; 31.4±4.5ml.kg.m-1; 32±3.7kg.m-2) and the Control Group (CG) (97.1±8.6kg; 26.2±5.8%BF; 0.98±0.08RC/Q; 33.3±6.8ml.kg.m-1; 32±3.5 kg.m-2). All the subjects underwent clinical and physical assessments. The TG trained for three sessions (average duration: sixty minutes) a week on alternate days, totaling 48 sessions, encompassing aerobic, strength and flexibility training at the Fitness Center, Petrobrás Research Center (CENPES). Their pre and pos-training BP was measured at rest by the auscultatory method, processing this data by the ANOVA two-way method with Scheffé post hoc when necessary (p<0.05) for intra and inter-group comparisons. Results: The TG posted a BP reduction of 9% in systolic BP (SBP) (P<0.05) and 2.2% in diastolic BP (DBP) (p>0.05) for the intra-group analysis. The intergroup analysis presented significant differences for the SBP, but not for the DBP. Significant differences were also noted in all other TG assessments, compared to the pretraining situation (84.1±6.5kg; 19.1±3.5%G; 0.92±0.07RC/Q; 38.3±5.9ml.kg.m-1; 27.1±2.8kg.m-2) and compared to the CG (98.6±10.2kg; 26.4±4.2%G; 0.98±0.06RC/Q; 32.2±8.1ml.kg.m-1; 32.1±2.,2kg.m-2) after physical training. Conclusion: The Fitness Program run at the Petrobrás Research Center (CENPES) resulted in lower BP among hypertensive medicated individuals after a four-month exercise program.
