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...

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...

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...

INTRODUCTION: IL-6 has been ascribed both positive and negative roles in the context of exercise and training. The dichotomous nature of IL-6 signalling appears to be determined by the respective concentration of its receptors (both membrane-bound (IL-6R) and soluble (sIL-6R) forms). The purpose of the present study was to investigate the response of sIL-6R to long-term training, and to investigate the relationship between sIL-6R, self-reported measures of wellbeing, and upper respiratory illness symptoms (URS) in highly-trained endurance athletes...

PURPOSE: Peaking for major competition is considered critical for maximizing team sports performance. However, there is little scientific information available to guide coaches in prescribing efficient tapering strategies for team sports players. The aim of this study was to monitor the changes in physical performance in elite team sports players during a 3-week taper following a pre-season training camp. METHODS: Ten male international rugby sevens players were tested before (Pre) and after (Post) a 4-week pre-season training camp focusing on high-intensity training and strength training with moderate loads, and once each week during a subsequent 3-week taper (T1, T2, T3)...

PURPOSE: Running performance is influenced by the interaction of biomechanical and physiological factors. Miniaturised accelerometers worn by the athlete can be used to quantify mechanical aspects of running and be used as a non-invasive tool to assess training status and progression. The aim of this study was to define and validate a method to assess running regularity and allow the estimation of an individual's V̇O2 and/or blood lactate [La]b based on data collected with accelerometers and heart rate (HR)...

While historically adolescents were removed from their parents to prepare to become warriors, this process repeats itself in modern times but with the outcome being athletic performance. This review considers the process of developing athletes and managing load against the backdrop of differing approaches of conserving and maximizing the talent available. It acknowledges the typical training 'dose' that adolescent athletes receive across a number of sports and the typical 'response' when it is excessive or not managed appropriately...

Expertise and training in fine motor skills has been associated with changes in brain structure, function, and connectivity. Fewer studies have explored the neural effects of athletic activities that do not seem to rely on precise fine motor control (e.g., distance running). Here, we compared resting-state functional connectivity in a sample of adult male collegiate distance runners (n = 11; age = 21.3 ± 2.5) and a group of healthy age-matched non-athlete male controls (n = 11; age = 20.6 ± 1.1), to test the hypothesis that expertise in sustained aerobic motor behaviors affects resting state functional connectivity in young adults...

Magnesium is essential for optimal sport performance, generating an interest to monitor its status in athletes. However, before measuring magnesium status in blood could become routine, more insight into its diurnal fluctuations and effects of exercise itself is necessary. Therefore, we measured the effect of an acute bout of exercise on ionized (iMg) and total plasma magnesium (tMg) in blood obtained from 18 healthy well-trained endurance athletes (age, 31.1 ± 8.1 yr.; VO2max, 50.9 ± 7.5 ml/kg/min) at multiple time points, and compared this with a resting situation...

Decision support systems are used in team sport for a variety of purposes including evaluating individual performance and informing athlete selection. A particularly common form of decision support is the traffic light system, where colour coding is used to indicate a given status of an athlete with respect to performance or training availability. However despite relatively widespread use, there remains a lack of standardisation with respect to how traffic light systems are operationalised. This paper addresses a range of pertinent issues for practitioners relating to the practice of traffic light monitoring in team sports...
