Exertional heat illness (EHI) is a leading cause of preventable death among student athletes. While causes and preventative measures for EHI are known, school districts may not be implementing evidence-based practices. This descriptive, exploratory study explored school policies, resources, and practices of coaches in a mid-Atlantic state in the prevention and identification of EHI; 397 responded. Ninety-three percent knew of EHI, but only 52% scheduled acclimatization. Coaches reporting a heat emergency plan (56%) were significantly more likely to follow other evidence-based recommendations: altering equipment ( p < ...

INTRODUCTION: Vertical Jump (VJ) is a good measure of athletic performance and occupational activities. Earlier studies reported conflicting results on anthropometric influence. AIM: To evaluate the relationship between anthropometric characteristics and VJ in national level hockey and cycling players. MATERIALS AND METHODS: Fifty four (32 males) national level hockey and cycling players of 11-21 years were the volunteers. Following standard protocols, these variables were measured: VJ, Weight (WT), Height (HT), Trochanterion-Height (TH), Sum of Skinfold Thickness (SSF), Lengths [Acromiale-Stylion (AS) and Midstylion-Dactylion (SD)], Breadths [Biacromial (AB), Biiliocristal (IB), Biepicondylar Humerus (HB) and Biepicondylar Femur (FB)], Girths [Relaxed Arm (AG), Mid Thigh (TG) and Calf (CG)], Lower Back and Hamstring Flexibility (SR), Grip [Left Hand Grip (LHG) and Right Hand Grip (RHG)] and Back Strength (BS)...

It is well known that exercise training can deeply affect redox homeostasis by enhancing antioxidant defenses. However, exhaustive exercise can induce excessive reactive oxygen species (ROS) production, leading to oxidative stress-related tissue injury and impaired muscle contractility. Hence, ROS represent important signaling molecules whose level has to be maintained to preserve normal cellular function, but which can also accumulate in response to repetitive muscle contraction. In fact, low levels of oxidants have been suggested to be essential for muscle contraction...

BACKGROUND: Elite rowers complete a high volume of training across a number of modalities to prepare for competition, including periods of intensified load, which may lead to fatigue and short-term performance decrements. As yet, the influence of substantial fatigue on resting metabolic rate (RMR) and exercise regulation (pacing), and their subsequent utility as monitoring parameters, has not been explicitly investigated in elite endurance athletes. METHOD: Ten National-level rowers completed a four-week period of intensified training...

We describe an approach to support athletes at various fitness levels in their training load analysis using heart rate (HR) and heart rate variability (HRV). A smartphone-based application (HRV4Training) was developed that captures heart activity over one to five minutes using photoplethysmography (PPG) and derives HR and HRV features. HRV4Training integrated a guide for an early morning spot measurement protocol and a questionnaire to capture self-reported training activity. The smartphone application was made publicly available for interested users to quantify training effect...

Training monitoring is about keeping track of what athletes accomplish in training, for the purpose of improving the interaction between coach and athlete. Over history there have been several basic schemes of training monitoring. In the earliest days training monitoring was about observing the athlete during standard workouts. However, difficulty in standardizing the conditions of training made this process unreliable. With the advent of interval training, monitoring became more systematic. However, imprecision in the measurement of HR evolved interval training toward index workouts, where the main monitored parameter was average time required to complete index workouts...

PURPOSE: To establish the relationship between the acute:chronic workload ratio and lower extremity overuse injuries in professional basketball players over the course of a competitive season. METHODS: The acute:chronic workload ratio was determined by calculating the sum of the current week's session rate of perceived exertion (sRPE) training load (acute load) and dividing it by the average weekly training load over the previous four weeks (chronic load). All injuries were recorded weekly using a self-reported injury questionnaire (Oslo Sports Trauma Research Centre Injury Questionnaire(20)) Workload ratios were modelled against injury data using a logistic regression model with unique intercepts for each player...

To achieve the criterion appearance prior to competing in a physique competition, athletes undergo preparatory regimens involving high-volume intense resistance and aerobic exercise with hypocaloric energy intake. As the popularity of "drug-free" competition increases, more athletes are facing this challenge without the recuperative advantage provided by performance-enhancing drugs. Consequently, the likelihood of loss of lean body and/or bone mass is increased. The purpose of this investigation was to monitor changes in body composition for a 29-year-old self-proclaimed drug-free female figure competitor during a 32-week preparatory regimen comprising high-volume resistance and aerobic exercise with hypocaloric energy intake...

BACKGROUND: The ketogenic diet (KD) is a very low-carbohydrate, high-fat and adequate-protein diet that without limiting calories induces different metabolic adaptations, eg, increased levels of circulating ketone bodies and a shift to lipid metabolism. Our objective was to assess the impact of a 6-week non-energy-restricted KD in healthy adults beyond cohorts of athletes on physical performance, body composition, and blood parameters. METHODS: Our single arm, before-and-after comparison study consisted of a 6-week KD with a previous preparation period including detailed instructions during classes and individual counselling by a dietitian...

Many risk factors for injury are presented in the literature, few of those are however consistent and the majority is associated with adult and not adolescent elite athletes. The aim was to identify risk factors for injury in adolescent elite athletes, by applying a biopsychosocial approach. A total of 496 adolescent elite athletes (age range 15-19), participating in 16 different sports, were monitored repeatedly over 52 weeks using a valid questionnaire about injuries, training exposure, sleep, stress, nutrition, and competence-based self-esteem...

PURPOSE: Quantifying external workload is fundamental to training prescription in sport. In tennis, global positioning data are imprecise and fail to capture hitting loads. The current gold standard (manual notation) is time intensive and often not possible given players' heavy travel schedules. The aim of this study was to develop an automated stroke classification system to help quantify hitting load in tennis. METHODS: 18 athletes wore an inertial measurement unit (IMU) on their wrist during 66 video-recorded training sessions...

This study aimed to validate the use of a single blood lactate concentration measurement taken following a 5-minute running bout at 10 km·h(-1) (BLC10 ) and the speed associated with 90% of maximal heart rate (S90 ) to predict and monitor fixed blood lactate concentration (FBLC) thresholds in athletes. Three complementary studies were undertaken. Study I: A cross-sectional study examining the associations of BLC10 and S90 with running speeds at FBLC of 3 (S3mM) and 4 mmol·L(-1) (S4mM) in 100 athletes. Study II: A cross-validation study assessing the predictive capacity of BLC10 and S90 to estimate FBLC thresholds in real practice...

CONTEXT: Despite rising awareness of the risks associated with sports participation, overuse injuries continue to increase in youth athlete populations. Physeal injuries are one type of overuse injury exclusive to pediatric populations that are often sustained during athletic practice or competition. Overuse physeal injuries are, in theory, preventable; however, little consensus has been reached surrounding the risk factors, prevention, and treatment strategies. OBJECTIVE: This systematic review summarizes the best available evidence concerning overuse physeal injuries in youth and adolescent athletes...
