No acute effect of whole-body vibration on Roundhouse kick and countermovement jump performance of competitive Taekwondo athletes
Abstract Little is known about the effect of whole body vibration (WBV) has on specific sports action such as taekwondo kicking technique. Fifteen individuals (10 males and 5 females; 18.6 ± 2.1 years), performed two experimental protocols on separate days: A) 1 minute exposure at 26 Hz frequency of WBV followed by countermovement jump (CMJ) test; B) 1 minute exposure at 26 Hz frequency of WBV followed by kick test. A Student's t-Test analysis was performed to evaluate the difference between performance before and after vibration intervention. The CMJ height means (cm) were 34.1 ± 6.4 before and 34.2 ± 6.5 after WBV exposure. The CMJ maximal force means were 1582.6 ± 214.3 before WBV and 1595.7 ± 205.0 after WBV, while Impulse means (N.s) were 283.3 ± 48.6 before WBV and 2 82.6 ± 46.6 after WBV. The kick time means (ms) were 219.9±20.31 before WBV and 218.9±19.81 after WBV. No significant differences were found regarding the application of mechanical vibration for all variables. Thus, the vibration intervention (1 minute of WBV at 26 Hz and 6 mm) adopted in this pr esent study may have not been substantial to improve Roundhouse kick time (p=0.73), jump height (p=0.80), maximal force (p=0.78) and impulse (p=0.38) of taekwondo athletes. Future studies should investigate new vibration protocols (amplitude, frequency) and training (intensity, exercise, duration) t o determine optimal parameters.Resumo Pouco se sabe so...
DiscussionThe interventions of education and medication alerts resulted in a significant increase in the percentage of patients receiving appropriate doses of dilTIAZem and a nonsignificant decrease in the incidence of hypotension. This process-oriented intervention resulted in an improvement in appropriate dilTIAZem doses at our site. Rate control was not statistically significantly different between the 2 groups. Long-term sustainability of this intervention requires further study.
ConclusionsVitamin D insufficiency was prevalent in both newly diagnosed axSpA patients and healthy controls. There was no association between vitamin D and pain and disease activity in the newly diagnosed axSpA patients. Monitoring vitamin D levels is important and early intervention for vitamin D insufficiency is needed, especially in female patients.
ConclusionVacuum assisted dressing is more effective than traditional wound dressing in wound healing of open fractures.
This study aims to reflect on the process of adoption of the preprints publication model, briefly delimiting its history and current use by the national and the international scientific community. Departing from the literature and a consultation of preprint repositories, this reflection intends to highlight the main challenges that preprint implementation will face in the Nursing area, along with its specificities. While considering its benefits for scientific dissemination, this study points out the difficulties that may arise from the implementation of mostly north-American science models in a peripheral country such as ...

CONCLUSIONS: Neonatal screening with the red reflex is not sufficient to detect intraocular disease. A normal neonatal red reflex does no exclude intraocular disease. It has a specificity of nearly 90%, but its sensitivity is only 56%. Most retinal haemorrhages are undiagnosed as they cannot be detected with a red reflex.
