Feasibility of the Allergy Questionnaire for Athletes (AQUA © ) in pediatric age

2018

A burden of respiratory and allergic symptoms up to almost 60% has been observed in young and adult athletes, influencing physical performances1 . The Allergy Questionnaire for Athletes (AQUA©) is a validated screening tool for the prediction of the atopic status in adult athletes2 ; it was recently tested in Belgian young elite athletes (12-14 years old)3 , but its actual feasibility and suitability for children and adolescent was not evaluated. Indeed, there is evidence that children are prone to employ "satisficing" response strategies, answering every question positively/negatively, or simply not answering4 . Therefore, the present cross-sectional survey was carried out to assess feasib…

Predictors of lower extremity injuries in team sports (PROFITS-study): a study protocol.

2015

Introduction Several intrinsic risk factors for lower extremity injuries have been proposed, including lack of proper knee and body control during landings and cutting manoeuvres, low muscular strength, reduced balance and increased ligament laxity, but there are still many unanswered questions. The overall aim of this research project is to investigate anatomical, biomechanical, neuromuscular, genetic and demographic risk factors for traumatic non-contact lower extremity injuries in young team sport athletes. Furthermore, the research project aims to develop clinically oriented screening tools for predicting future injury risk. Methods Young female and male players (n=508) from nine basket…

SELF-REPORTED 12-MONTH OVERUSE INJURY HISTORY IN YOUTH BASKETBALL AND FLOORBALL

2014

Background The popularity of organized sports, especially team sports is growing among youth. High training volume and intensity at early age may predispose young athletes to overuse injuries. Objective To examine the occurrence, nature and severity of overuse injuries in youth basketball and floorball. Design A descriptive retrospective study. Setting Finnish youth basketball and floorball. Participants: 406 athletes (mean age 15.9, SD 2.0) from six basketball and floorball clubs (210 basketball and 196 floorball players). Main outcome measurements Self-reported history of overuse injuries over the preceding 12-month period. Data was obtained from a questionnaire. The severity of injuries …

Individual Sprint Force-Velocity Profile Adaptations to In-Season Assisted and Resisted Velocity-Based Training in Professional Rugby

2020

We tested the hypothesis that the degree of adaptation to highly focused sprint training at opposite ends of the sprint Force-Velocity (FV) spectrum would be associated with initial sprint FV profile in rugby athletes. Training-induced changes in sprint FV profiles were computed before and after an eight-week in-season resisted or assisted sprint training protocol, including a three-week taper. Professional male rugby players (age: 18.9 &plusmn

Treadmill and Running Speed Effects on Acceleration Impacts: Curved Non-Motorized Treadmill vs. Conventional Motorized Treadmill

2021

An increase in the popularity of running can be seen over the last decades, with a large number of injuries on it. Most of the running injuries are related to impact accelerations and are due to overuse. In order to reduce the risk of injury or to improve performance and health new treadmill designs have been created, as it can be the curved non-motorized treadmill. The aim of this study was to analyse impact accelerations, spatio-temporal parameters and perceptual differences while running on curved non-motorized treadmill (cNMT) compared to motorized treadmill (MT) at different speeds. Therefore, 27 recreational runners completed two tests consisting of 10 min warm-up and three bouts of 8…

Validity of the Acute Recovery and Stress Scale: Training Monitoring of the German Junior National Field Hockey Team

2015

The aim of the present study was to examine the sensitivity of the Acute Recovery and Stress Scale (ARSS). This new psychometric questionnaire was developed to assess the physical, mental, emotional, and overall recovery and stress states of athletes. During a five-day field hockey training camp of the German Junior National Field Hockey Team ( n = 25) the ARSS was administered every morning and evening. The study indicated swift reactions of the scores of the physical and general factors as well as stability of scores for the emotional factors in accordance with the training schedule. The straining effect of the camp was best reflected by the adaptations of the scales Physical Performance…

Occlusal Splints and Exercise Performance: A Systematic Review of Current Evidence

2021

The role of the dento-mandibular apparatus and, in particular, occlusion and jaw position, received increased attention during last years. In the present study, we aimed to systematically review, on the light of the new potential insights, the published literature covering the occlusal splint (OS) applications, and its impact on exercise performance. A structured search was carried out including MEDLINE®/PubMed and Scopus databases with additional integration from external sources, between March and June 2021. To meet the inclusion criteria, studies published in the English language, involving humans in vivo, published from 2000 to 2021 and that investigated the role of occlusal splints on …

Relationships between Heart Rate Variability, Sleep Duration, Cortisol and Physical Training in Young Athletes.

2021

The aims of the current study were to examine the relationships between heart rate variability (HRV), salivary cortisol, sleep duration and training in young athletes. Eight athletes (16 ± 1 years) were monitored for 7 weeks during training and competition seasons. Subjects were training for endurance-based winter sports (cross-country skiing and biathlon). Training was divided into two zones (K1, easy training and K2, hard training). Heart rate and blood lactate during submaximal running tests (SRT), as well as cortisol, sleep duration and nocturnal HRV (RMSSD), were determined every other week. HRV and cortisol levels were correlated throughout the 7-week period (r = -0.552, P = 0.01), wi…

Evaluation of knee joint proprioception and balance of young female volleyball players: a pilot study

2015

[Purpose] The main purpose of our study was the evaluation of the effects of long-term volleyball practice on knee joint proprioception and balance of young female athletes. [Subjects and Methods] An observational case-control study was performed. The study enrolled 19 female volleyball players in the experimental group and 19 sedentary counterparts as controls. A Biodex balance system and dynamometer were used for the evaluations. The paired t-test was used to determine the significance of differences between the performance of athletes and controls. [Results] The knee proprioception analysis showed a significant difference at 60° joint position in active and passive tests. A similar trend…
