Characteristics of functional movement screening testing in elite handball players: Indicative data from the 9.

Objectives: To test 9 + screening batterie's intra-rater reliability, to provide indicative data of elite handball players, and to analyze difference between age, playing positions and level of play.

Design: Descriptive study.

Setting: Icelandic elite male handball players.

Can movement tests predict injury in elite orienteerers? An 1-year prospective cohort study.

The purpose of this study was to determine the predictive value of the movement test, the nine test screening battery (9TSB) and an orienteering-modified version of the 9TSB (M9TSB), for lower extremity injury in adolescent elite orienteerers. Prospective cohort study. Forty adolescent (15-19 years), male and female orienteerers from two Swedish orienteering high schools performed the 9TSB, M9TSB, and recorded injuries based on a web-based questionnaire for 52 weeks.

Young, talented and injured: Injury perceptions, experiences and consequences in adolescent elite athletes.

Even though injury is common in elite sports, there is still a lack of knowledge of young athletes' injury perception both during and after injury. The aim of this mixed-method study was, therefore, to explore, in-depth, data on injury consequences and adolescent elite athletes' perceptions and experience of injury. Three hundred and forty adolescent elite athletes (age range 15-19), from 16 different sports, were bi-weekly monitored over 52 weeks using a valid questionnaire.

High Injury Burden in Elite Adolescent Athletes: A 52-Week Prospective Study.

Context:   Our understanding of the injury burden in elite adolescent athletes in most sports is limited or unknown because of the lack of prospective, long-term injury studies.

Objective:   To describe injury patterns in terms of type, location, prevalence and incidence, recurrence, and severity grade; time to first injury; and prevalence of illness in elite adolescent athletes and to compare differences in injury data by sex and sport type.

Design:   Cohort study.

INJURY PATTERNS IN ADOLESCENT ELITE ENDURANCE ATHLETES PARTICIPATING IN RUNNING, ORIENTEERING, AND CROSS-COUNTRY SKIING.

Background: Prospective injury registration studies, monitoring adolescent elite athletes, are sparse in running, orienteering and cross-country skiing, yet essential for developing prevention programs.

Purpose: The aims of this study were to describe the injury prevalence/incidence, severity grade, injury location, risk factors and the prevalence of illness in running (RU), orienteering (OR) and cross-country skiing athletes (CR).

Study Design: Prospective cohort study.

Menstrual irregularity and use of oral contraceptives in female adolescent athletes in Swedish National Sports High Schools.

Objective Female adolescent athletes seem to use oral contraceptives (OCs) in the same proportion as the general population. In athletes not using OCs, menstrual irregularity (MI) is reported to be common but there are few studies of MI in adolescent athletes. The aim of the study was to survey menarche, menstrual irregularity and use of OCs in adolescent athletes in the National Sports High Schools in Sweden.

Multiple factors explain injury risk in adolescent elite athletes: Applying a biopsychosocial perspective.

Many risk factors for injury are presented in the literature, few of those are however consistent and the majority is associated with adult and not adolescent elite athletes. The aim was to identify risk factors for injury in adolescent elite athletes, by applying a biopsychosocial approach. A total of 496 adolescent elite athletes (age range 15-19), participating in 16 different sports, were monitored repeatedly over 52 weeks using a valid questionnaire about injuries, training exposure, sleep, stress, nutrition, and competence-based self-esteem.

THE NINE TEST SCREENING BATTERY - NORMATIVE VALUES ON A GROUP OF RECREATIONAL ATHLETES.

Background: A variety of risk factors predispose athletes to injury, such as impaired neuromuscular control, insufficient core stability, and muscular imbalances. The goal of assessing functional movement patterns is to detect imbalances and correct them with prevention strategies and thereby decrease injuries, and improve performance and quality of life.

Purpose: The purpose of this study was to generate normative values for the 'Nine Test Screening Battery' (9TSB) in a group of recreational athletes.

Too little sleep and an unhealthy diet could increase the risk of sustaining a new injury in adolescent elite athletes.

Little is known about health variables and if these variables could increase the risk of injuries among adolescent elite athletes. The primary aim was to present overall data on self-perceived stress, nutrition intake, self-esteem, and sleep, as well as gender and age differences, on two occasions among adolescent elite athletes. A secondary aim was to study these health variables as potential risk factors on injury incidence.

Injuries and Associated Risk Factors Among Adolescent Elite Orienteerers: A 26-Week Prospective Registration Study.

Context: In orienteering, the number of injury-registration studies is limited. Most researchers have used a cross-sectional design during specific events and, therefore, have mainly identified acute injuries.

Objective: To determine the prevalence of injuries by registering acute and overuse injuries in adolescent elite orienteerers over 26 weeks and to study the variation of injury prevalence over the season and the potential risk factors.

Swedish translation and validation of a web-based questionnaire for registration of overuse problems.

The main aim of this study was to translate the Oslo Sport Trauma Research Center (OSTRC) Overuse Injury Questionnaire into Swedish. The validity and applicability of the questionnaire for studying overuse injuries among Swedish handball, volleyball, tennis, and orienteering top athletes were also examined. The back-translation method was used for translation.

A nine-test screening battery for athletes: a reliability study.

Studies have shown that reduced neuromuscular control or strength increases the risk of acute injuries. It is hypothesized that a non-functional movement pattern can predispose for injuries. In the present paper a detailed description of a test battery consisting of nine different tests to screen athletic movement pattern is provided.

Patellar tendon load in different types of eccentric squats.

Background: Differences in mechanical loading of the patellar tendon have been suggested as a reason for varying effects in rehabilitation of patellar tendinopathy using different eccentric squat exercises and devices. The aim was to characterize the magnitude and pattern of mechanical load at the knee and on the patellar tendon during four types of eccentric squat.

Methods: Subjects performed squats with a submaximal free weight and with maximal effort in a device for eccentric overloading (Bromsman), on a decline board and horizontal surface.

Eccentric treatment for patellar tendinopathy: a prospective randomised short-term pilot study of two rehabilitation protocols.

Objective: To compare the efficacy and safety of two eccentric rehabilitation protocols for patients with symptomatic patellar tendinopathy. A new eccentric overload training device was compared with the present standard eccentric rehabilitation programme on a decline board.

Design: Prospective, randomised clinical trial.

A new device for controlled eccentric overloading in training and rehabilitation.

The aim of this work was to evaluate a device that allows for eccentric overload to be applied under controlled and safe conditions and it is applicable in exercises commonly used in training and rehabilitation. The machine contains a barbell, which is lowered and raised by a motor, following a predetermined velocity profile. It is capable of handling heavy loads (>500 kg) and is instrumented with a sensor to measure the velocity of the barbell and two scales to measure the vertical component of the ground reaction force.

Psychometric properties of a Swedish translation of the VISA-P outcome score for patellar tendinopathy.

Background: Self-administrated patient outcome scores are increasingly recommended for evaluation of primary outcome in clinical studies. The VISA-P score, developed at the Victorian Institute of Sport Assessment in Melbourne, Australia, is a questionnaire developed for patients with patellar tendinopathy and the patients assess severity of symptoms, function and ability to participate in sport. The aim of this study was to translate the questionnaire into Swedish and to study the reliability and validity of the translated questionnaire and resultant scores.
