Active clinical trials for "Athletic Injuries"

Overall Goal: Elaboration of an evidence-based, national prevention strategy to protect the health of competitive alpine skiers, with a particular focus on youth athletes. Background: Competitive alpine skiing has a relatively high injury risk. 60% of all athletes suffer from a severe knee injury in the early stages of their career, and 20% struggle with recurrent overuse problems of the knee and lower back. Research Aims: (1) to investigate the effects of a 12-month sports injury prevention program on training attitudes, eccentric hamstring strength, leg axis-/hip-/core-stability and general fitness in competitive alpine skiers; (2) to assess the effectiveness the aforementioned prevention program to lower the occurring health problems in competitive alpine skiers; (3) to identify different pain conditions (knee, back, no pain) based on data measured with smartphones; and (4) to investigate the agreement of self-reported questionnaire data with measured smartphone data and pain as an affecting factor. Methods: 12-month intervention a sports injury prevention program, a prospective health- and training/activity-monitoring, as well as assessments of eccentric hamstring strength, leg axis/hip/core stability and general fitness at baseline and follow-up.

Physiotherapy protocols based on high-intensity interval training (HIIT) or eccentric hamstring exercises like Nordic Curl (NC) have been scarcely studied in futsal players. The hypothesis of this study is that a HIIT combined with an NC exercise program is more effective than a HIIT-only program in improving physical and functional characteristics in futsal players.

Three male and three female semi-professional athletes, ranging in age from 22 to 27, participated in a study that was done at Lund University in Sweden to examine their physiological responses. The temperature and relative humidity were adjusted at 40 degrees Celsius for hot, dry conditions and 31 degrees Celsius for hot, wet conditions, respectively. The participants were instructed to engage in physical activity on a treadmill within the chamber for 70 minutes, or until participants were able to continue their exercise without difficulty within the allotted period. Participants were instructed to walk (5 kph) and run (8 kph). Participants pulse rate, breathing rate, oxygen consumption, and subjective reactions were all recorded. On the basis of the Wet Bulb Globe Temperature (WBGT), a heat stress index, the American College of Sports Medicine has made certain suggestions. The technique used to determine the temperature on a Celsius scale took into account the influences of relative humidity, air temperature, wind, and direct sunlight radiation. The American College of Sports Medicine advises delaying athletic competition when the WBGT is above 28 degrees. In the climate control chamber, the trials were carried out in high-risk circumstances (28 degrees Celsius WBGT). According to the study's findings, exercise is influenced by weather, and as air temperature rises, so do the intensity of exertion and thermal feeling.

This study aims to evaluate the use of an aerial human body manoeuvre to reduce the biomechanical load on the neck of a parachutist during the parachute opening, in order to create a basis for future prevention of skydiver neck pain in the parachutist population.

Soccer accounts for more than 10% of all sport injuries in youth requiring medical attention. The injury rates in youth soccer where there is no established injury prevention program are estimated at 22-30 injuries/100 participants/year, or 3.4-5.6 injuries/1000 participation hours. Risk reductions ranging from 32-43% have been found for youth players participating in neuromuscular training programs, such as the FIFA 11+, that include agility, balance training, and strengthening components. Although studies have shown that the FIFA 11+ is effective at reducing injuries, there is poor uptake of the program in the youth soccer community. It is therefore important to develop ways of delivering the program to soccer coaches and players in order to maximize its protective benefit. The Health Action Process Approach (HAPA) is a behavior change theory that has been used to successfully predict the uptake of health behaviours in a number of populations, such as cancer screening and exercise, but has not been tested in sport injury prevention settings. The primary objective of this study is to examine the effect of a HAPA-based coach education intervention on adherence to the FIFA 11+ in a group of female youth soccer players over the course of one outdoor and one indoor season. The secondary objective is to examine the dose-response relationship between program adherence and injury, comparing program adherence and injury rates in outdoor and indoor soccer. Our hypothesis is that teams whose coaches receive a HAPA-based intervention will have greater adherence to the program than teams whose coaches do not receive the intervention, and that that injury incidence will decrease as adherence to the program increases. It is expected that program adherence will be lower and injury rates will be higher in indoor soccer compared to outdoor soccer.

American football is a team activity that calls for many difficult qualities, including speed, endurance, speed, strength, and quickness. It is getting more and more popular among professional and amateur players, particularly in our nation.

Screening Brain magnetic resonance imaging (MRI) with Fluid-attenuated Inversion Recovery (FLAIR) and Susceptibility Weighted Imaging (SWI) sequences will be performed pre and post season on high school football players. One set of players will wear the Guardian Cap on their five star rated helmets and the other will wear five star rated helmets only. The investigators will compare outcomes of ImPACT scores and MRI findings between the two groups to see if there is a statistical difference in reduction of injury and to establish what the baseline level of MRI findings related to injury from high school football is as well as what the baseline level of injury is prior to the start of the season.

In this study, we examine how acute to chronic workload ratio and functional movement screen scores relate to injury risk in teenage athletes who play team sports.

The purpose of this study is to complete a neuromuscular performance assessment of high school athletes who are participating in school based pre-season strength and performance training program. The performance assessment will screen for existing muscle imbalances and strength deficits known to increase risk for sports injury, and provide a baseline performance measurement. Athletes will be measured before the start of the program and then again at the end of the pre-season training period to measure changes in motor coordination, muscle strength, and performance and injury risk category. Internal and external training load will be measured weekly during the training program to track intensity of the training program. In addition to the pre and post measurements, sports injury occurrence and time away from sports participation will be tracked throughout the sport season/school year to evaluate training program outcomes and accuracy of risk assessment.

The purpose of this study is to examine the acute neural responses to subconcussive head impacts in individuals with Attention-deficit/hyperactivity disorder (ADHD). The study is designed to identify the effects of 10 controlled soccer headings in college-aged soccer players diagnosed with ADHD and without ADHD, through the use of neural-injury blood biomarkers, functional and diffusion MRI, and ocular-motor function across three acute timepoints. The central hypothesis is that neuronal structural, physiological, and functional impairments from subconcussive head impacts will be amplified by ADHD. The neural-injury blood biomarkers neurofilament light (NF-L), glial fibrillary acidic protein (GFAP), ubiquitin C-terminal hydrolase-L1 (UCHL-1), and Tau will be measured in plasma, with the hypothesis that 10 soccer headings will significantly increase plasma NF-L levels in both groups at 24h post-heading compared to baseline, but this increase will be higher in the ADHD group; plasma UCH-L1, GFAP, and Tau levels will increase significantly after 10 headings in the ADHD group at 2h and 24h post-heading, but levels in the non-ADHD group will remain consistent throughout the time points. It is also hypothesized that repetitive subconcussive head impacts will impair neurocognitive function, as measured by regional changes in fMRI activation during working memory and attention-based tasks, in the ADHD group. Ten headings will significantly alter fMRI activation in the ADHD group from baseline. This impairment will not be observed in the non-ADHD group, rather the non-ADHD group will show consistent fMRI activation even after 10 headings. White matter microstructure will be measured by diffusion imaging metrics, with the hypothesis that 10 soccer headings will significantly disrupt microstructure in the ADHD group compared to baseline, but not in the non-ADHD group. The study will also assess neuro-ophthalmologic function as measured by the King-Devick test (KDT) and oculomotor function as measured by the near-point-of-convergence (NPC) in response to subconcussive head impacts. The hypothesis is that NPC performance will be significantly impaired and persist for longer than 24 hours in both groups, but this impairment will be greater in the ADHD group, and that the learning curve and expected improvement of KDT will be significantly blunted in both groups, with a display of worsening in the ADHD group.
