Not Applicable

Completed

• Conditions: Athletic Injuries
• Interventions: Behavioral: Control group; Behavioral: I-PROTECT model

• Registration Number: NCT05304507
• Lead Sponsor: Lund University

Brief Summary

This pilot study aims to test a tailored model (the I-PROTECT model) for implementation of injury prevention training in youth handball compared with current practice.

Detailed Description

Injury prevention training is effective in reducing musculoskeletal injuries in youth athletes but has had limited public health impact because it is not widely or properly implemented. The lack of involving end-users at the individual and organizational levels is a main contributor to insufficient implementation.

This is a non-randomized pilot study included in the "Implementing injury Prevention training ROutines in TEams and Clubs in youth Team handball (I-PROTECT)" project. The overall aim of I-PROTECT is to achieve wide-spread, sustained and high-fidelity use of evidence-based injury prevention training in youth handball through behavior change at multiple levels within the sports delivery system (individual and organizational levels). The I-PROTECT model is evidence-based, theory-informed, and context-specific injury prevention training specifically tailored for youth handball players, incorporating physical and psychological components and an associated implementation strategy. The process of developing the I-PROTECT model has been described.

In a prospective single-case study (ClinicalTrials.gov registration number: NCT04481958), the I-PROTECT model was implemented and tested in all youth teams (n=19) of two clubs during the 2020/2021 handball season. Due to Covid pandemic restrictions, handball training was only performed for about 2 months, thus, affecting intervention implementation and data collection. To further evaluate, develop, and finalize the I-PROTECT model, we will in the current study conduct pilot testing in clubs not involved in developing the model, before testing the model in a larger scale study.

Two clubs in Sweden offering handball for youth players will be recruited by convenience sampling. One club will use the I-PROTECT model (experimental) and one club will use current practice (control). Intervention will be approx. 6 weeks. Data will be collected among stakeholders (players, coaches, club administrators, caregivers) before, during and after the intervention. Parametric, or non-parametric, tests will be used as appropriate for main and secondary outcomes. Data will be used to calculate sample size in the main outcome for a larger scale study as well as to assess implementation determinants.

Arm && Interventions

Group	Intervention	Description
Control group	Control group	Youth coaches in the control group club will be asked to use injury prevention training available in the coach education material ("Ready for handball"), i.e., current practice in Sweden.
I-PROTECT model	I-PROTECT model	The I-PROTECT model is an end-user-driven intervention including evidence-based, theory-informed, and context-specific injury prevention training for youth handball, and an associated implementation strategy.

Primary Outcome Measures

Name	Time	Method
Frequency of injury prevention training	Study start up to end of study (6 weeks)	Frequency of injury prevention training on a team level, reported by coaches weekly (0, 1, 2, 3 or more session/week). Using injury prevention training for two session or more per week at regular handball training over the intervention period will signify that injury prevention is implemented in a team (binary outcome: ≥2 per week or \<2 per week).

Secondary Outcome Measures

Name	Time	Method
Adoption and fidelity (coaches)	Study start up to end of study (6 weeks)	Coaches' weekly report if they have followed the program as intended.
Implementation determinants	After study end at approx. 6 weeks	Questionnaire or interview data for implementation determinants will be collected for all stakeholders (players, coaches, caregivers, club representatives). Questions aligned with the Health Action Process Approach (HAPA) theory and the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework will be adapted to each stakeholder group. Data will also be gathered (e.g., focus groups interviews) to enable an in-depth understanding of potential barriers and facilitators, acceptability, usability, and sustainability of the I-PROTECT model, including its packaging, and of potential barriers for filling in questionnaires.
