OBJECTIVE: To present recommendations for the prevention, recognition, and treatment of exertional heat illnesses to describe relevant physiology thermoregulation. BACKGROUND: Certified athletic trainers evaluate treat heat-related injuries during activity in "safe" high-risk environments. While recognition illness has improved, subtle signs symptoms associated with are often overlooked, resulting more serious problems affected athletes. The presented here provide allied health providers an...
Abstract Exertional heat stroke (EHS) is a true medical emergency with potential for organ injury and death. This consensus statement emphasizes that optimal exertional illness management promoted by synchronized chain of survival promotes rapid recognition management, as well communication between care teams. Health providers should be confident in the definitions, etiologies, nuances exhaustion, injury, EHS. Identifying athlete suspected EHS early course, stopping activity (body...

Authors of most field studies have not observed decrements in physiologic function and performance with increases dehydration, although authors well-controlled laboratory consistently reported this relationship. Investigators these did control exercise intensity, a known modulator body core temperature.To directly examine the effect moderate water deficit on responses to various intensities warm outdoor setting.Semirandomized, crossover design.Field setting.Seventeen distance runners (9 men,...
Abstract Context: When assessing exercise hyperthermia outdoors, the validity of certain commonly used body temperature measuring devices has been questioned. A controlled laboratory environment is generally less influenced by environmental factors (eg, ambient temperature, solar radiation, wind) than an outdoor setting. The these in a may be more acceptable. Objective: To assess and reliability compared with rectal individuals exercising controlled, high indoor setting then resting cool...
A proper heat-acclimatization plan in secondary school athletic programs is essential to minimize the risk of exertional heat illness during preseason practice period. Gradually increasing athletes' exposure duration and intensity physical activity environment minimizes heat-illness while improving performance. Progressive acclimatization especially important initial 3 5 days summer practices. When an athlete undergoes a program, physiologic function, exercise tolerance, performance are all...
Research evaluating the effect of comprehensive coach education and practice contact restriction in youth football injury rates is sparse. In 2012, USA Football released their Heads Up coaching program (HUF), Pop Warner (PW) instituted guidelines to restrict during practice.To compare among players aged 5 15 years by whether leagues implemented HUF and/or were PW-affiliated.Cohort study; Level evidence, 2.Athletic trainers (ATs) evaluated tracked injuries at each game 2014 season. Players...
Despite little evidence that defines a threshold of head impact exposure or participation in youth sports leads to long-term cognitive impairments, it is prudent identify methods reducing the frequency impacts.To compare mean number impacts between football players practice and games leagues implemented Heads Up Football (HUF) educational program those did not (NHUF).Cohort study; Level evidence, 2.During 2014 season, was measured using xPatch accelerometers from 70 aged 8 15 years 5...
The purpose was to assess whether body cooling between 2 bouts of exercise in the heat enhances performance during second session. Using a random, crossover design, 15 subjects (3 women, 12 men; 28 +/- years, 180 cm, 69 2.3 kg) participated all 3 trials. Subjects ran 90 minutes on hilly trails hot environment (approximately 27 degrees C) before either cold water immersion (CWI; 13.98 C), ice (IWI; 5.23 or mock treatment (MT) sitting tub with no (29.50 C). After immersion, 2-mile race. CWI...
Abstract Context: Previous researchers have not investigated the thermoregulatory responses to multiple consecutive days of American football in adolescents. Objective: To examine and hydration high school players during formal preseason practices. Design: Observational study. Setting: Players practiced outdoors late August once per day on 1 through 5, twice 6 7, 8 10. Maximum wet bulb globe temperature averaged 23 ± 4°C. Patients or Other Participants: Twenty-five heat-acclimatized...
Introduction Data on exertional heat illness (EHI) in youth football are limited and have not been compared across competition levels. Purpose This study describes the epidemiology of EHI events youth, high school (HS), college 2012–2014 seasons. Methods One hundred eighteen teams (players age 5–14 yr), 96 HS programs (~14–18 34 (~18–23 yr) participated. During games practices, athletic trainers recorded athlete exposures (AE), defined as one participating game/practice. We calculated number...
Context Exertional heat illnesses (EHIs) among football athletes have been widely researched, but data examining all collegiate sports are limited. Objective To describe the epidemiology of EHI in 25 National Collegiate Athletic Association (NCAA) sports. Design Descriptive study. Setting The NCAA Injury Surveillance Program during 2009–2010 through 2014–2015 academic years. Patients or Other Participants A voluntary sample 166 institutions over 2048 team-seasons. Main Outcome Measure(s)...
The purpose of this consensus document was to develop feasible, evidence-based occupational heat safety recommendations protect the US workers that experience stress. Heat were created worker health and avoid productivity losses associated with Recommendations tailored be utilized by managers, industrial hygienists, employers who bear responsibility for implementing plans. An interdisciplinary roundtable comprised 51 experts assembled create a narrative review summarizing current data gaps...
This investigation evaluated the new National Collegiate Athletic Association model of heat acclimatization for football players using physiological, psychological, fluid balance, anthropometric, and nutritional variables. Eleven (20 +/- 1 year, 1.88 0.05 m, 115.36 18.85 kg) from a Division I team were observed first 8 days preseason practices. Measurements such as heart rate gastrointestinal temperature (T(GI)) via telemetric sensor taken before, 3 times during, after practice daily. An...
Purpose: To assess the hydration status and level of knowledge youths at summer sports camps. Methods: Sixty-seven active youths, 57 males (mean ± SD, 12 2 y, 136 16 cm, 50.6 21.1 kg) 10 females (13 153 8 45.2 9.0 participated in 4 d camp. Hydration was assessed before first practice (AM) after second (PM). Participants completed suriveys assessing (HAQ) habits on day 3 a self-assessment (EQ#1). Results: Mean AM urine specific gravity (USG) osmolality (U osm ) scores ranged from minimal to...
Diuretic-induced dehydration impairs prolonged running performance (> 1500 m). Sprinting may suffer by similar mechanisms (i.e., altered cardiovascular strain, heat storage, and metabolism) or improve because of reduced mass to accelerate carry.To examine sprint power after diuretic-induced dehydration.After six practice sessions, nine male former sprinters (mean +/- SD; age, 21 2 yr; body (BM), 80.0 5.2 kg; height, 1.78 0.08 m; fat, 14 4%) participated in a 50-m race, 200-m 400-m vertical...
Context: Previous field research has not identified sweat rates (SR), fluid consumption (FC), or the efficacy of an educational intervention (EI) for youth during football camp. Objective: To measure hydration status and rehydration performance examine EI using these data. Design: Observational with randomized comparison. Participants: Thirty-three boys (mean ± SD: 12 2 y, 52.9 13.6 kg, 156 cm) volunteered a 5-d camp 3 (~2-h) sessions per day (WBGT: 25.6 0.5°C). Main Outcome Measures:...
Background: American youth football leagues are typically structured using either age-only (AO) or age-and-weight (AW) playing standard conditions. These conditions group players by age in the former condition and a combination of weight latter condition. However, no study has systematically compared injury risk between these 2 standards. Purpose: To compare rates tackle AO AW Study Design: Cohort study; Level evidence, 2. Methods: Athletic trainers evaluated recorded injuries at each...
Context: Without a true criterion standard assessment, the sport-related concussion (SRC) diagnosis remains subjective. Inertial balance sensors have been proposed to improve acute SRC but few researchers studied their clinical utility. Objective: To determine if group differences exist when using objective measures of in sample collegiate athletes with recent SRCs and participants serving as control calculate sensitivity specificity diagnostic utility inertial sensor for injuries.
