INTRODUCTION: Shoulder-to-head contact is the most common cause of concussions in ice hockey, accounting for 42% of cases in the National Hockey League (NHL). The goal of this project was to determine how shoulder pad stiffness, modified by adding foam padding over the shoulder cap of existing shoulder pads, affected head impact severity when participants delivered checks to an instrumented dummy. METHODS: Fifteen participants administered "the hardest shoulder checks they were comfortable delivering" to the head of a dummy equipped with tri-axial accelerometers and gyros mounted in its helmet...

This study determined whether mild dehydration influenced skeletal muscle glycogen use, core temperature or performance during high-intensity, intermittent cycle-based exercise in ice hockey players vs. staying hydrated with water. Eight males (21.6 ± 0.4 yr, 183.5 ± 1.6 cm, 83.9 ± 3.7 kg, 50.2 ± 1.9 mL·kg(-1)·min(-1)) performed two trials separated by 7 days. The protocol consisted of 3 periods (P) containing 10 x 45-second cycling bouts at ~133% VO2max, followed by 135 seconds of passive rest. Subjects drank no fluid and dehydrated during the protocol (NF), or maintained body mass by drinking WATER...

We present a case of simultaneous ipsilateral fractures at the intra-articular second metacarpal head, intra-articular fourth metacarpal base, and ulnar styloid. These fractures were caused by the peculiar condition of a blow to the fist during an ice hockey game; the hand was struck while it was gripping a stick. The specific combination of these fractures has not been previously reported in the literature. In this incident, axial compression force was transmitted from the second and fourth metacarpal heads while skipping the third metacarpal head to the ulnar side of the wrist via the carpometacarpal joints and carpal bones...

BACKGROUND: Effective approaches that engage men in weight loss and lifestyle change are important because of worldwide increases, including in Canada, in obesity and chronic diseases. Football Fans in Training (FFIT), developed in Scotland, successfully tackled these problems by engaging overweight/obese male football fans in sustained weight loss and positive health behaviours, through program deliveries at professional football stadia. METHODS: Aims: 1) Adapt FFIT to hockey within the Canadian context and integrate with HealtheSteps™ (evidence-based lifestyle program) to develop Hockey Fans in Training (Hockey FIT); 2) Explore potential for Hockey FIT to help overweight/obese men lose weight and improve other outcomes by 12 weeks, and retain these improvements to 12 months; 3) Evaluate feasibility of recruiting and retaining overweight/obese men; 4) Evaluate acceptability of Hockey FIT; and 5) Conduct program optimization via a process evaluation...

Mild traumatic brain injury results in aberrant free radical generation, which is associated with oxidative stress, secondary injury signaling cascades, mitochondrial dysfunction, and poor functional outcome. Pharmacological targeting of free radicals with antioxidants has been examined as an approach for treatment, but has met with limited success. Conventional antioxidants currently available scavenge a single free radical, before they are destroyed in the process. Here, we report for the first time, that a novel regenerative cerium oxide nanoparticle antioxidant reduces neuronal death and calcium dysregulation after in vitro trauma...

Wearable kinematic sensors can be used to study head injury biomechanics based on kinematics and, more recently, based on tissue strain metrics using kinematics-driven brain models. These sensors require in-situ calibration and there is currently no data conveying wearable ability to estimate tissue strain. We simulated head impact (n=871) to a 50(th) percentile Hybrid III (H-III) head wearing a hockey helmet instrumented with wearable GForceTracker (GFT) sensors measuring linear acceleration and angular velocity...

BACKGROUND/AIM: Dupuytren disease is a fibroproliferative hand condition. The role of exposure to vibration as a risk factor has been studied with contradictory results. Since field hockey is expected to be a strong source of hand-arm vibration, we hypothesised that long-term exposure to field hockey is associated with Dupuytren disease. METHODS: In this cross-sectional cohort study, the hands of 169 male field hockey players (IQR: 65-71 years) and 156 male controls (IQR: 59-71 years) were examined for signs of Dupuytren disease...

Two experiments were conducted to examine framing effects in sport. In Experiment 1, a conceptual replication [Loftus, E. F., & Palmer, J. C. (1974). Reconstruction of automobile destruction: An example of the interaction between language and memory. Journal of Verbal Learning and Verbal Behavior, 13(5), 585-589], participants watched a hockey collision, with the hit described later in a written format as a "contact", "bump", or "smash". This manipulation resulted in no differences in participants' report of how fast the players were skating, their intentions, and the outcome of the hit...
