Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This request pertains to a series of related projects on a common theme. Specifically, this set of projects aims to analyze the impact of new alternatives in materials and structures of artificial turf on athlete performance and perception, within the context of the elimination of microplastics as per Commission Regulation (EU) 2023/2055 of September 25, 2023. Third-generation sports artificial turf is notable for including performance infill (granules) that provide the necessary functionality and safety for sports practice. The vast majority of fields worldwide use materials that do not comply with the new European regulation, which has granted an eight-year moratorium. Therefore, there is little time to find new alternatives. The challenge lies not only in developing new structural solutions but also in understanding their impact on athletes. This issue is of high severity, as these sports facilities are the largest in terms of space and host the highest number of Physical Activity and Sports practitioners in Europe (mainly Football, Rugby, Hockey, and Padel).

For this reason, over the past year, the IGOID Group has requested various projects to cover all the necessary phases and nuances to address this issue.

The activities included in these projects are divided into two phases:

Phase 1: Evaluation of Sports Surfaces in the Laboratory (durability and surface-player and surface-ball interaction). Tests will be conducted on artificial turf samples constructed with SBR rubber (the main material to be replaced under the EU regulation), natural-origin infills, polymeric infills larger than 5 mm, and other infills. Initially, a market analysis and classification will be carried out, followed by laboratory tests. Across all projects, a minimum of 30 alternatives are expected to be analyzed.

Phase 2: Field Study. Tests will be conducted on a sample of athletes on constructed surfaces representing the different alternatives evaluated in Phase 1. Performance tests and a battery of assessments will be carried out to understand athlete perception. A sample of 30 athletes will be randomly divided into groups to perform different repetitions of the test batteries, covering a minimum of six different sports facilities.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

The study employs a crossover design to evaluate the impact of different artificial turf materials on athlete performance and perception. Participants, consisting of 30 amateur football players, will be randomly divided into groups. Each group will test six different types of artificial turf surfaces in a randomized order. The study includes a familiarization session followed by performance tests and perception assessments conducted over seven sessions. Each session lasts approximately two hours and includes various physical tests such as sprints, jumps, and small-sided games. The crossover design ensures that all participants experience each type of turf, allowing for comprehensive comparisons and minimizing bias. Data collected will be analyzed to determine the mechanical properties of the surfaces and their influence on athlete performance and perception.
