Results: Post-intervention there was a statistically significant reduction in systolic BP levels (mean: 126.05 vs 129.37, p < 0.001, intervention (IG) and control (CG) group, respectively). A 35.7% of the IG receded BP category vs. 17.5% of the CG (p < 0.001). After controlling for gender, age, educational level and BP cutoffs, we found significant improvements in stress, anxiety, self-esteem, spirituality, body weight, hours of sleep and in the subscales of the Healthy Lifestyle and Personal Control Questionnaire. Concerning the sub-categories of chance and powerful others in the health locus of control scale, improvements were recorded for the individuals of tertiary education.Conclusions: This non-pharmaceutical stress management and lifestyle change program resulted in significant benefits for regulation of BP, as well as for body weight, lifestyle and the psychosocial wellbeing of the participants. Future nonpharmaceutical programs are strongly encouraged both for the clinical and the community settings.Objective: The aim of this study was to evaluate the vascular benefits of an aerobic exercise program, particularly over the endothelial function and the central arterial hemodynamics in healthy young individuals. Design and method:A randomized controled study was conducted involving 60 healthy and young sedentary subjects, randomized into two groups: control group (CG, n = 30) and intervention group (IG, n = 30). The IG completed a plan of aerobic exercise, which consisted of a daily 45 minute brisk walk (weekly -5 days) for a month. All the individuals were submitted to two clinical evaluations, basal and after one month, in which their weight, height, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), flow-mediated dilation (FMD), Augmentation Index(AIX), aortic pulse wave velocity (PWV) and pulse wave analysis over the carotid artery (PWA) were assessed.Results: CG and IG were homogeneous from the point of view of fundamental demographic characteristics. After intervention, no significant changes in BMI and brachial SBP in CG were found, however these variables have been improved in the IG. Central systolic blood pressure significantly decreased in the GI (108.13 ± 6.87 to 104.07 ± 5.30mmHg, p = 0.043). No significant variations of central PP were found in both groups (p = 0.196 for CG and p = 0.459 for IG), although the IG exhibited a trend towards a PP reduction after the intervention. The AiX improved significantly after the exercise period in IG (p = 0.040), but not in the CG. Aortic PWV did not change significantly over time in both groups. As for the FDM, a significant increase was depicted in the IG after the intervention (7.40 ± 3.91% at baseline and 11.47 ± 3.51% post-intervention, p = 0.03), but no significant changes were seen in the CG (8.87 ± 4.63% at baseline and 8.42 ± 5.65% after intervention, p = 0.536). Conclusions:The practice of regular moderate-intensity aerobic exercise, for one month, improves vascular function in young healthy ind...

OBJECTIVE:This study aimed to evaluate the influence of acute muscle stretching on manual function. METHODS:The sample consisted of 10 untrained men in a randomized, four test session cross-over experimental design. Each session was composed of only one of two protocols: a) control, or b) single series of passive static stretching; followed by either Minnesota Hand dexterity test or hand grip strength test with eletromyographical recording of reaction time. For data comparison, the Student T-test with significance level of p ≤ 0.05 was used. RESULTS: Manual dexterity increased after stretching for both placing and turning tests, with no changes in hand grip strength or reaction time. CONCLUSION:The results show that a 30 second static stretch of the hand decreases time to complete the Minnesota Hand Dexterity test without affecting handgrip strength or hand reaction time; thus it improves manual dexterity of young untrained men. KEYWORDS:Muscle stretching, motor skills, reaction time. ■ INTRODUCTIONStretching exercises are often prescribed for persons with reduced motor skills or range of motion. Several reports describe this exercise technique as a necessary activity for better performance in daily life activities.1-4 However, muscle stretching seems to evoke neural and mechanical adaptations that reduce strength, reaction time and body balance; 3,5-7 it also affects the responsiveness of relevant afferent structures, such as muscle spindles 8 and Golgi tendon organs, 9 which are important structures in the regulation of motor commands.Manual dexterity, handgrip strength and reaction time are important components to assess hand function, which relate to better quality of daily life 1,10 and recreational activities; 2,11 they also act as indicators of cognitive and exercise performance 12,13 and are determinant factors in the ability to manipulate objects.14 Additionally, manual dexterity and handgrip strength are closely interdependent, in an interaction known as strength-dexterity trade-off. 15Manual dexterity is also related to the central nervous system, since the cortex receives information from several proprioceptors 8,16 to modulate manual motor tasks increasing movement efficiency.14,17-19 Hence, if muscle stretching does interfere with these factors it could alter the ability to manipulate objects. Because several sports, such as boxing, 20 handball, 21 basketball, 22 and many non-sporting activities such as musical performance 23 require agility and manual dexterity, the assessment of hand function is essential for the development of training techniques and functional rehabilitation of hand movements. However, there is a lack of knowledge about the effect of static stretching on manual dexterity. We hypothesized that muscle stretching would interfere with these factors and consequently alter hand dexterity.The purpose of this study was to understand the effect of static stretching on manual dexterity, providing evidence for health professionals seeking to prescribe stretching exercises safely and effi...
