Brief Summary

The primary aim of this hybrid-effectiveness-implementation cluster randomised study is to investigate if a supported implementation of an injury prevention exercise program (Happy program) involving a train-the-trainer workshop and coach support during the season is superior to an unsupported implementation of the Happy program involving the availability of the program on webpages, in improving adherence (volume, frequency, duration) of the Happy program among coaches for young (11-17 years of age) Danish female and male handball players during one handball season. Secondary aims are to investigate if the supported implementation is superior to the unsupported implementation in improving behavioural outcomes among the coaches and in reducing the risk for new ankle, knee, and shoulder injuries among young (11-17 years of age) Danish female and male handball players during one handball season. Further, the investigators aim to evaluate how and why adherence and behavioural determinants towards use of the Happy program might improve (or not).

Outcome Measures

Primary Outcomes (2)

• Adherence volume at team level

  How much the Happy components have been delivered (adherence volume) will be evaluated as the number of Happy components delivered per week at team level over the full season Reports of Happy program usage will be recorded electronically on a weekly basis by the head coach of each team using a web application. A full warm-up session includes 7 components. A full resistance exercise training includes 4 components. The coaches are encouraged to perform all Happy program components with their players twice a week

  Measured weekly over 7 months

• Shoulder, knee and ankle injuries using the Oslo Sports Trauma Research Center Health problems Questionnaire (OSTRC-H2)

  The primary injury outcomes will be time to any new handball-related ankle, knee and shoulder injury defined as any tissue damage or other derangement of normal physical function due to participation in handball, resulting from rapid or repetitive transfer of kinetic energy, following a recent consensus statement from the International Olympic Committee Injury status will be monitored weekly during the season using the Oslo Sports Trauma Research Center Overuse Injury Questionnaire distributed electronically to the players via an application. The questionnaire also measures exposure to handball, both training and match, during the last seven days.

  Measured weekly over 7 months

Secondary Outcomes (6)

• Adherence volume of the Happy warm-up components at team level

  Assessed weekly over 7 months

• Adherence volume of the Happy resistance training components at team level

  Assessed weekly over 7 months

• Adherence volume of the Happy resistance training components at player level

  Assessed weekly over 7 months

• Substantial shoulder, knee and ankle injuries using the Oslo Sports Trauma Research Center Health problems Questionnaire (OSTRC-H2)

  Assessed weekly over 7 months

• Health Action Process Approach (HAPA) Questionnaire responses

  Will be assessed at baseline, mid-season (3 months after baseline) and at end season (7 months)

Other Outcomes (13)

• Training volume

  Assessed weekly over 7 months

• Match volume

  Assessed weekly over 7 months

• Illness outcomes using the Oslo Sports Trauma Research Center Health problems Questionnaire (OSTRC-H2)

  Assessed weekly over 7 months

Supported Implementation (Intervention)

EXPERIMENTAL

The Happy-program will be available online on a webpage and consists of 7 warm-up components and 4 resistance training components that can be completed after handball practice. The warm-up program has three exercise variations for each of the seven components. The coaches may deliver the four resistance training components in the field or in the gym. The resistance training components in the field and the gym targets the same four body areas but differs in that the components in the gym are performed with equipment, while the components in the field can be performed without equipment. Each resistance training component has three levels. Happy ambassadors (Health professionals with a handball player or coach background) will conduct a 3-hour train-the trainer workshop in the beginning of the season and provide coaches with the opportunity for support throughout the season. At mid-season, the ambassadors will re-visit the clubs for 1,5-hour supervision and support.

Interventions

Happy program BEHAVIORAL

The Happy program consists of handball specific warm-up components and resistance training components and will be available online.

Supported Implementation (Intervention); Unsupported implementation (control)

Support BEHAVIORAL

The support consists of a coach workshop at the beginning of the season and the opportunity for additional support for the coaches throughout the season.
