"I'd rather do that (Knee Control) than be injured and not able to play": a qualitative study on youth floorball players' and coaches' perspectives of how to overcome barriers for injury prevention exercise programme use.

This study explored youth floorball players' and coaches' perspectives on using the injury prevention exercise programmes (IPEPs) or ( programmes) and how to overcome barriers to programme use. We used a qualitative design with eight semistructured focus group discussions, six with players, 11-17 years old (n =42) and two with coaches (n =12). Data analysis followed the principles of qualitative content analysis.

'We may need some help; we are just parents who have chosen to engage in football': a qualitative study on amateur coaches' experiences of use of and support for injury prevention training in Sweden.

Introduction: Achieving sufficient adherence with injury prevention exercise programmes is a challenge. The aim was to explore how amateur football coaches experience the use of and support for injury prevention training using the programmes as examples.

Methods: Semistructured interviews with 20 amateur football coaches around experiences of injury prevention training, facilitators and barriers, and perceived support, analysed with qualitative content analysis.

To play or not to play, that is the question: an interview study with amateur football coaches on perceptions of pain during sports participation.

Amateur football coaches play a key role in preventing, assessing and treating pain among their players, as they are often the first point of contact and may be the main source of advice and guidance. The objective of this study was to explore amateur football coaches' perceptions of pain during sports participation and their approach to pain management. We conducted a qualitative interview study with 20 amateur football coaches from a strategically selected sample of male and female, and junior and senior teams.

Players are positive regarding injury prevention exercise programmes, but coaches need ongoing support: a survey-based evaluation using the Health Action Process Approach model across one season in amateur and youth football.

Objectives: Implementation of injury prevention exercise programmes (IPEPs) in sports is challenging, and behaviour change among players and coaches is essential for success. The aim was to describe players' and coaches' motivation and coaches' goal pursuit when using IPEPs in amateur and youth football across a season. A secondary aim was to describe players' motivation to engage in IPEP use in relation to presence or absence of injury.

Effect of exercise intensity and apnea on splenic contraction and hemoglobin increase in well-trained cross-country skiers.

The human spleen acts as a reservoir for red blood cells, which is mobilized into the systemic circulation during various conditions such as hypoxia and physical exertion. Cross-country (XC) skiers, renowned for their exceptional aerobic capacity, are regularly exposed to high-intensity exercise and local oxygen deficits. We investigated a putative dose-dependent relationship between splenic contraction and concomitant hemoglobin concentration ([Hb]) elevation across four exercise intensities in well-trained XC skiers.
