Traumatic Osteonecrosis in the Distal Ulna.
BACKGROUND Futsal is a team sport involving intermittent technical actions of high intensity, and high physical (strength) and muscular demands. In this regard, the Tensiomyography (TMG) is a useful and non-invasive tool for the monitoring and assessment of the muscle's contractile capacity. This study aimed to analyze the changes in the contractile properties produced during the season, as well as to determine the potential cumulative effect of a resistance training (RT) program in futsal players. METHODS Fourteen elite futsal players (2 goalkeepers, 4 defenders, 4 wingers and 3 pivots) were assessed by TMG at 11th, 18th, and 28th week of the season. The maximal radial displacement of the muscle belly (Dm); contraction time (Tc); delay time (Td) and radial displacement velocity (90%) Dm (VrD90) were assessed. After the second measurement, a RT program was included in the regular training sessions and focused on the lower body musculature. It was performed during 9 weeks (1-weekly). Finally, a third measuremefic. In addition, an in-season 9-week RT program (1-weekly), had no significant effects (time points 2-3) on the contractile properties of futsal players. In addition, there were no differences when comparing different positions.BACKGROUND Swimming relay events have the concern regarding a good start is shared between the incoming and outgoing swimmers. The aim of this study was to evaluate changes in exchange block time (EBT) for swimming relay events as a result of a four-week training programme using the occlusion technique. METHODS Twenty-eight national swimmers, 12 males (age 17±1.83 years) and 16 females (age 19.94±5.65 years) participated in this study. Subjects were required to undergo a training programme on visual perception in relay swimming over the course of four weeks; they watched videos corresponding to the last movements of a swimmer during a 4×100m freestyle relay event. The videos were presented with temporal occlusion corresponding to predetermined approaching distances (7.5m, 5.0m, and 2.5m). Swimmers were required to simulate a typical position for exiting the block and to estimate the time-to-contact of the incoming swimmer. The EBT was collected during a real 4x100m freestyle competition before and after the application of the training programme. RESULTS Female swimmers showed a decreased in EBT, with an improvement of 1.42%, despite there not being a significant difference (p= 0.68). The male swimmers had a higher improvement in EBT after the training, with a decrease of 13.34% (p= 0.68). CONCLUSIONS Visual perception practice using video occlusion techniques seems to have a positive effect. On EBT in swimming relay events, particularly in female swimmers.BACKGROUND Negative functionality changes are among the effects of aging. The multicomponent training performed on conventional machines or with new implements and features directed to daily activities is strongly recommended among attenuation strategies. However, the efficiency of both types of training is not yet clear in the current literature. The aim was to compare the effects of different multicomponent training methods on functional parameters in older women. METHODS Thirty-seven volunteers were randomly selected into the functional multicomponent training (MFT n=15), traditional multicomponent training (MTT n=14) and control group (CG n=8). They were assessed in the tests 6-minute walk test (6MWT), 10-minute fast walking test (10FWT), time up and go (TUG), functional reach test (FRT), ankle test (AKT), sit to stand modified (STSM) and quality of life (QOF). ANOVA (3x2) followed by bonferroni post hoc was used, adopting p ≤0.05 for statistical significance. RESULTS When compared pre-post values, MFT showed significant differences in all functional tests evaluated (AKT p less then 0.01; STSM p less then 0.01; FRT p less then 0.01; QOF p less then 0.01; 10FWT p less then 0.01; 6MWT p less then 0.01; TUG p less then 0.05). In the same comparison, MTT showed a significant change in all tests (AKT p less then 0.01; STSM p less then 0.01; FRT p less then 0.01; QOF p less then 0.05; 6MWT p≤0.05; TUG p less then 0.05) except 10FWT. When compared to CG, MFT showed a significant difference in all walking tests and MTT showed a better performance in 10FWT and TUG. CONCLUSIONS Both experimental protocols were effective to improve functional parameters in older women. However, the MFT was performed better in most tests that required efficiency in gait ability.BACKGROUND Few studies have examined the effect of acupuncture (AC) treatment in aerobic capacity and endurance performance in healthy adults. Thus, the aim of the present study was to evaluate the effects of AC on selected physiological parameters and 3 km running performance. METHODS Twenty four healthy subjects with low to moderate aerobic capacity participated in the study and randomly assigned in two groups AC group (ACG - N=14) and control group (CG - N=10). The subjects completed an incremental test to exhaustion and a 3 km race on a treadmill to evaluate their physiological responses and endurance running performance respectively, prior and after 4 weeks (8 sessions, twice a week) of acupuncture treatment. RESULTS AC treatment had a significant main effect in T3km [F(1, 21)=7,173, p=0,014, partial η2=0,255], as well as in VT [F(1, 21)=8,476, p=0,008, partial η2=0,288] and HRmax@3km [F(1, 21)=4,930, p=0,038, partial η2=0,190], after controlling for the effect of the pre-test, while no other significant main effects were detected. MDV3100 price CONCLUSIONS Healthy physically active adults significantly improved their endurance running performance after 4 weeks of AC treatment. This is mainly due to the enhancement of the speed corresponding with VT, comparing with their baseline values.BACKGROUND Physical exercise interventions have showed improvement on cognitive performance and mobility of old people. However, the results regarding the inclusion of cognitive activities into exercise were not evaluated simultaneously. Therefore, the aim of this study was to investigate the effect of multimodal exercise program on cognitive function and physical performance in elderly people with mobility disabilities. METHODS The sample of the study consisted of 70 old people randomly appointed to the exercise and control groups (35 people for each) with mobility disabilities. A new exercise program was conducted for old people in the exercise group for 6 months. Evaluation between 1st and 24th week included cognitive change, mobility, balance and walking parameters. RESULTS Exercise group showed better performance on orientation, memory and language point than before the intervention (p less then 0.05). Again, the total mental test score of the exercise group significantly increased from [18.7±3.5] to [20.
