Post-race reactions: The emotional paradox of high performance and anxiety - a conventional content analysis.

Background: Studies examining post-race emotional experiences in the context of endurance races among recreational athletes are scarce. The purpose of this study was to describe how recreational athletes experience the time after completing an endurance race.

Methods: In this study, a qualitative study design was used, and data collection was carried out with semi-structured interviews.

Changes in Physical Fitness in Youth Padel Players during One Season: A Cohort Study.

The aim of this study was to investigate how physical fitness performance, which is related to the strength and power of the lower extremities and core, as well as lateral agility, changes across 20 weeks of in-season training in youth female and male padel players. This study was conducted using a prospective cohort design on 16 Swedish high school padel players aged between 15 and 18 years old. The players were assessed at baseline with five tests of their physical fitness and followed prospectively, with the registration of their training load for 20 weeks, and then assessed at a follow-up, approximately five months later.

Can tests of physical fitness predict traumatic knee injury in youth female athletes? A prospective cohort study.

Objectives: To compile a battery of test including various aspects of physical fitness that could be used on the field and to assess whether any of these tests are associated with future traumatic knee injuries in youth female team sports athletes.

Design: Prospective cohort.

Setting: Sport setting.

FIDES Athlete Development Programme: project background and study protocol of an embedded multiple case study.

Most sports science research revolves around male subjects. As a result, most of the knowledge and practices within sports are male-centric. Failing to take the biological, psychological and social (biopsychosocial) particularities of females into account is believed to hinder optimal sports participation, development and performance, with potential negative effects on the health and well-being of females.

The Significance of Maximal Squat Strength for Neuromuscular Knee Control in Elite Handball Players: A Cross-Sectional Study.

Both weak muscle strength and impaired neuromuscular control has previous been suggested as risk factors for future traumatic knee injury. However, data on the relationship between these two factors are scarce. Thus, the aim of this study was to investigate the relationship and influence of the one repetition maximum (1RM) barbell squat strength on dynamic knee valgus in elite female and male handball players.

A test battery for evaluation of muscle strength, balance and functional performance in subjects with chronic ankle instability: a cross-sectional study.

Background: Studies investigating ankle condition in subjects with chronic ankle instability (CAI) using an on-the-field test battery are scarce. Understanding which tests that are most challenging for these subjects has the potential to set realistic goals in rehabilitation and return-to-sports criteria. Thus, the primary aim of this study was to investigate CAI subjects regarding strength, balance and functional performance with an easily used test battery that required minimal equipment.

Development of a Novel Nordic Hamstring Exercise Performance Test Device: A Reliability and Intervention Study.

There is evidence that a knee flexor exercise, the Nordic hamstring exercise (NHE), prevents hamstring injuries. The purpose of this study was therefore to develop, and to determine the reliability of, a novel NHE test device and, further, to determine the effectiveness of a 10-week low volume NHE program on NHE performance. Twenty female football (soccer) players, aged 16-30 years, participated in this study.

Short-term effects of postural taping on pain and forward head posture: a randomized controlled trial.

Background: Balance Body Tape (BBT) is a recently developed taping-method with the aim to reduce pain and improve posture through change in movement behavior. However, the potential effects of a treatment with BBT are scarcely documented. Therefore, the aim with this study was to investigate the effect of a three-week Balance body tape-treatment on the intensity of perceived neck, shoulder and back pain and forward head posture.

Postural orientation, what to expect in youth athletes? A cohort study on data from the Malmö Youth Sport Study.

Background: Studies investigating postural orientation in uninjured youth athletes are scarce. Understanding how postural orientation during functional performance tests change with age in uninjured athletes has the potential to enhance awareness of changes in performance after injury and to set realistic goals for injured athletes. Thus, the aim of this study was to explore postural orientation during functional tasks at early adolescence, and changes in postural orientation from early to middle adolescence and relate this to sex, type of sport and right leg lean body mass (RLLBM).

Jump height as performance indicator for the selection of youth football players to national teams.

Background: Different jump tests such as the Countermovement Jump (CMJ), Abalakov Jump (AJ) and Standing Long Jump (SLJ) are often used in practice to evaluate muscular power and functional performance in football. These tests are also used in different selection processes and talent identification, but the significance of the tests for the selection of youth players to national teams are relatively unknown. The aim of this study was to compare jump ability between youth football players selected or not selected for the national team.

Vertical drop jump landing depth influences knee kinematics in female recreational athletes.

Objectives: To examine whether different vertical drop jump (VDJ) landing depth (small versus deep) and stance width (wide versus narrow) may alter movement biomechanics in female recreational athletes. The purpose was also to identify whether leg muscle strength is a predictive factor for knee control during a VDJ.

Design: Cross-sectional.

Weaker lower extremity muscle strength predicts traumatic knee injury in youth female but not male athletes.

Background: The role of lower extremity (LE) muscle strength for predicting traumatic knee injury in youth athletes is largely unknown.

Aims: The aim was to investigate the influence of LE muscle strength on traumatic knee injury in youth female and male athletes.

Methods: 225 athletes (40% females) from sport senior high schools in Sweden were included in this case-control study.
