Filter by:Baseball batting is important to winning the games. Baseball batting is achieved by proximal-to-distal sequencing of body movements and controlled by the neuromuscular system. Poor lumbopelvic control could influence production and transfer of energy in the kinetic chain. This study aims to investigate the effects of functional movement training on hitting mechanics and bat swing velocity in high school baseball players.
Physical inactivity is one of the major contributing factors for the development of chronic diseases and highly correlated with increased all-cause mortality. In the last decade an exponential growth in research concerned with the study of sedentary behaviour and the potential for detrimental effects on health have been published. In this field increasing evidence suggests that prolonged periods of sedentary time, independent of the amount of physical activity, also increases the risk for the development of several chronic conditions and all-cause mortality. Here, sedentary behaviour is defined as "any waking behaviour, characterized by a low energy expenditure (≤1.5 METs), while being in a sitting or reclining posture". Interestingly, the advised moderate-to-vigorous bouts of exercise recommended by the various guidelines cannot compensate the negative impact on health risks arising from prolonged periods of sitting. In other words, it seems that people compensate their total amount of physical activity after exercise training by decreasing their physical activity levels throughout the rest of the day. Here, it appears that frequent, even low-intensity interruptions of periods of sitting are required for good cardiometabolic health. Therefore, not only physical activity but also prolonged sitting should be targeted to optimize cardiometabolic health. Nevertheless, a recent harmonized meta-syntheses indicated that the association between self-reported sitting with all-cause and cardiovascular disease mortality are only partially independent of physical activity, but were particularly evident in those who undertake insufficient physical activity (<150min/week). However, it is unclear whether high amounts of objectively measured physical activity attenuates or even eliminates the detrimental effects of prolonged sitting. In addition, it is still unclear whether high amounts of physical activity can preserve a healthy cardiometabolic risk profile, despite prolonged sitting. Therefore, in this study we want to investigate the association between sedentary behaviour, physical activity and cardiometabolic health in highly physically active adults.
In the competitive swimming scenario, there is a significant incidence of pain, which can be justified by the high levels of training that exposes athletes to constant stress. In this way, the quantification of pain and its monitoring becomes extremely important for clinical practice. A commonly used tool with easy access and clinical applicability, capable of measuring the pain threshold (PT) in a standardized manner is the pressure algometer. However, there is a shortage in the literature of studies that evaluate the reliability of this instrument in healthy swimming athletes. Objectives: Evaluate the intra and inter-examiner reliability and to describe the profile of the PT measurements measured by the algometer in swimming athletes. Methods: It is a reliability study, and will be composed of fifty young athletes members of swimming teams, of both genders, aged between 12 and 20 years. The evaluation will be carried out on the same day and in 2 steps: (1) Test and (2) Retest. In the first step, through a third examiner, the participants will be subjected to marking of points in pre-determined muscles and in points of referred pain. Next, they will perform the PT assessment through the algometer by two other distinct and trained examiners. The interval between each examiner will be five minutes with the participant at rest. After five minutes the test was performed, the step retest will begin, which will have the same procedures as in the previous step. The statistical package SPSS Statistics 23.0 will be used to conduct the analyzes.
The clinical analysis of athletes has been performed in the sports field to obtain parameters for reliable evaluations. Among the tools used is the myotonometry, an analysis capable of quantitatively measuring tone, stiffness and elasticity. Its reliability has been tested in several populations, however, showing changes in results and presenting high variability in the confidence interval, also, the values of myotonometry differ according to sample specificity and the biomechanical properties of each muscle. Therefore, it seems pertinent to perform the reliability analysis in swimming athletes and verify their applicability and if the values of tone and muscular biomechanical properties vary according to the specificity of the modality. It will be a test and retest study composed of 50 young male and female swimming athletes, aged between 12 and 20 years. The evaluation of myotonometry will be performed randomly by two evaluators and the parameters measured will be: tone, stiffness, elasticity, relaxation time of mechanical stress and displacement. In the test stage, the first evaluator will perform the measurements bilaterally on the muscles and the second evaluator will perform the same measurements in the same order immediately after the first one. After 15 minutes, the retest will be performed following the same order of evaluators in the test. For characterization of sample will be used descriptive statistic through central tendency and variability for all variables collected. Relative reliability will be tested by the Intraclass Correlation Coefficient (ICC). Absolute reliability will be verified by means of standard error of measurement (SEM), values of least detectable change (MMD) and coefficient of variation (CV). The statistical package SPSS Statistics 22.0 will be used to conduct the reliability analyses.
To evaluate the intra- and inter-rater reliability of a test of active shoulder proprioception with a laser pointer in swimming athletes and to describe the profile of the proprioception measures characterizing the sample according to the specialty within the sport and the category of the athletes.
Introduction: Late-onset muscle pain (DOMS) is characterized by a type of temporary muscle damage, common after high-intensity exercise. In addition to pain, DOMS clinically generates muscle stiffness, reduced joint range of motion, muscle weakness and reduced peak torque. In this regard, in order to accelerate the recovery of body systems and treat symptoms of DOMS, the management of different types of interventions has been observed, supporting the clinical practice, based on evidence. Objectives: To investigate the effect of different types of clinical interventions for the treatment of DOMS. Material and methods: For the clinical trial, 50 ultramarathon and rowing athletes of both sexes, aged between 18 and 60 years old, will be recruited randomly into four possible groups: control (CG), shock waves (G1) , massage (G2) and laser therapy (G3). The evaluation moments will be as follows: minutes before exercise (M1); immediately after exercise (M2); immediately after applying the recovery technique (M3); and 24 hours after exercise (M4) and the evaluated outcomes will be: pain, psychological aspects, functional test and blood markers.

The aim of the study is to characterize the diet and iron status of young female elite football players and examine the relationship between iron intake, iron status, hemoglobin levels, intestinal health and sports performance. In addition, the effects of low-dose iron supplements on iron stores will be investigated and whether such supplementation affects intestinal health, microbiota composition and biomarkers for oxidative stress.
The purpose of this study is to test how cocoa-rich procyanidin B2 affect the mitochondrial exercise adaptations.
I. Title of Proposed Research Project Dextrose 10% Drink Increase Blood Sugar and Sprint Velocity Compared to Sodium Dextrose in Soccer Players II. Specific Aims This study aims to evaluate the ergogenic effect in terms of blood sugar, VO2 max and sprint speed of dextrose 10% compared with sodium dextrose 10% in young male soccer players. III. Background Sports drinks are designed to provide CHO, electrolytes, and fluids to the body, which are absorbed very fast from the small intestine. In other words, the period from ingestion until the CHO, electrolytes, and fluids reach the muscles, brain and so on, should be very short. This is the most important advantage of using sports drinks (Simulescu, Ilia, Macarie, & Merghes, 2019). Commercial sports drinks generally contain both of CHO and sodium; To the best of the investigator's knowledge, there is no trial in which compare the differential effect of solely dextrose supplementation versus sodium dextrose in soccer players in terms of BG concentration, VO2 max and sprint speed, which may give a new paradigm for the available ergogenic sports drink.
