Brief Summary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The central hypothesis is such that a football player who regularly practices tackling and blocking drills without a helmet in a controlled environment will naturally leave the head out of contact and is likely to continue to do so while wearing the helmet during games and full-contact practices. This learned motor behavior will reduce the number of head impacts a football player experiences throughout their playing career and thus reduces the risk of acute and chronic head and neck injury.
The investigation will be a pre-test, post-test quasi experimental design using an evidence-based helmetless tackling and blocking program (HuTT®) with football players (\~200) recruited from high school football teams in Oahu, Hawaii.
Year 1 will serve as a baseline and entail collecting only head impact data during regular football participation for two teams. After adding a third team for years 2 and 3, all subjects will then undergo the HuTT® Program intervention emphasizing proper tackling and blocking techniques under closely supervised drills where players participate without their helmets and shoulder pads in place.
From the outset, subjects will use a new Speedflex helmet outfitted with the InSite™ head impact sensor (Riddell, Co). The helmet and sensor will be worn in all practices and games and used to record head impact exposure (frequency, location, and magnitude). ImPACT tests will be conducted at pre- and post-season intervals to measure verbal and visual memory composite, visual motor speed composite, reaction time composite and symptoms scores. In addition, player self-efficacy for head-safe behavior will be scored each year using a self-reported survey.
A between-subjects ANOVAs will be used to compare outcome measures among teams. Significant interactions and main effects will be identified by appropriate t-tests with Bonferonni corrections at an alpha-level of 0.05.

HuTT-2x
The HuTT® program emphasizes proper tackling and blocking techniques using a progressive series of closely supervised drills. Skill rehearsal is done without helmets and shoulder pads and is the inherent element of HuTT® in order to reinforce behaviors which remove the head as a point of contact. The HuTT® program is modeled after basic tackling/blocking drills familiar to the sport of football. Feedback to confirm or correct proper skill development is provided by coaches trained in the HuTT® technique. HuTT® drills are conducted at an intensity of 50-75% effort and over a period of approximately 10 minutes. The intervention will be conducted 2 times each week throughout the regular season.
