About

This study aims to better understand how head impacts during ice hockey affect the brain and body, especially in young athletes. Even when players do not show clear signs of concussion, these repeated impacts may cause subtle changes in the brain's structure and in how the body regulates basic functions, such as heart rhythm and attention.

This study will follow elite junior ice hockey players over the course of one full season to better understand the effects of repeated head impacts. Using a small helmet sensor (Bearmind) and video analysis, researchers will record and analyze every head impact that occurs during games and practices.

Three times during the season - before, mid-season, and after - players will complete assessments of heart rate variability (using Polar H10 monitors) and a dual-task test that measures attention and coordination.

After any diagnosed concussion, players will be reassessed with both heart rate variability and dual-task testing at 3 days post-injury. Following that, dual-task testing alone will be repeated every 3 days until return to sport. Players who experience a severe head impact, as detected by the helmet sensor, will also be evaluated 3 days after the impact with both heart rate variability and dual-task testing, even if no concussion symptoms are present.

By combining these measures, the study aims to detect early physiological and cognitive changes following head impacts, improve understanding of sub-concussive effects, and support better prevention and management strategies for young athletes.

Young Hockey Players

Description:

Elite junior ice hockey players will be monitored over one full season. Each player will wear a helmet sensor (Bearmind) to record head impacts. Heart rate variability (Polar H10) and dual-task tests will be conducted pre-, mid-, and post-season. After any concussion, both measures will be repeated at 3 days post-injury, with dual-task testing every 3 days until return to sport. Following a severe head impact, assessments will occur 3 days post-impact.

Treatment:

Other: Heart rate variability monitoring

Other: Dual-task cognitive and motor assessment

Device: Head impact monitoring
