Limited information exists about the movement patterns of field-hockey players, especially during elite competition. Time-motion analysis was used to document an international game. In addition, repeated-sprint activity were investigated, as ability is considered be important fitness component team-sport performance. Fourteen members Australian men's team (age 26+/-3 years, body mass 76.7+/-5.6 kg, VO2max 57.9+/-3.6 ml.kg(-1).min(-1); mean+/-s) filmed game and their analysed. The majority...
Ab initio protein secondary structure (SS) predictions are utilized to generate tertiary predictions, which increasingly demanded due the rapid discovery of proteins. Although recent developments have slightly exceeded previous methods SS prediction, accuracy has stagnated around 80 percent and many wonder if prediction cannot be advanced beyond this ceiling. Disciplines that traditionally employed neural networks experimenting with novel deep learning techniques in attempts stimulate...

Purpose: The purpose of the present study was profile aerobic anaerobic energy high-speed treadmill exercise that simulated 200-, 400-, 800-, track events. Methods: Twenty athletes (Australian National Standard) participated study, specializing either 200-m (N = 3), 400-m 6), 800-m 5), or 6) event (mean O2 peak...
Purpose: International women’s team handball is a physically demanding sport and intermittent in nature. The aim of the study was to profile high-intensity events (HIEs) international matches with regard playing positions. Methods: Twenty female national-team players were equipped inertial movement units (OptimEye S5, Catapult Sports, Australia) 9 official matches. Players categorized 4 different positions: backs, wings, pivots, goalkeepers (GKs). PlayerLoad™, accelerations (Acc), changes...
To assess the reliability and sensitivity of commercially available inertial measurement units to measure physical activity in team handball.Twenty-two handball players were instrumented with 2 (OptimEye S5; Catapult Sports, Melbourne, Australia) taped together. They participated either a laboratory assessment (n = 10) consisting 7 handball-specific tasks or field 12) conducted 12 training sessions. Variables, including PlayerLoad™ movement analysis (IMA) magnitude counts, extracted from...
Aim: The aim of the present study was to determine validity position, distance traveled and instantaneous speed team sport players as measured by a commercially available local positioning system (LPS) during indoor use. In addition, investigated how placement field play relative anchor nodes walls building affected system. Method: LPS (Catapult ClearSky T6, Catapult Sports, Australia) reference [Qualisys Oqus, Qualisys AB, Sweden, (infra-red camera system)] were installed around capture...
Abstract In this study, we investigated the age-related differences in repeated-sprint ability and blood lactate responses 134 youth football players. Players from development programme of a professional club were grouped according to their respective under-age team (U-11 U-18). Following familiarization, participants performed test [6 × 30-m sprints 30 s apart, with active recovery (2.0–2.2 m · s−1) between sprints]. The variables total time, percent sprint decrement, post-test peak...
Purpose: To compare active versus passive recovery on performance and metabolism during a test of repeated-sprint ability. Methods: Nine males performed four cycle tests (six 4-s sprints, every 25 s) in randomized, counterbalanced order: two with (~32% VO2max) recovery. Muscle biopsies were taken the from vastus lateralis pretest, immediately posttest, following 21 s to determine phosphocreatine ([PCr]), creatine, muscle lactate concentration ([MLa−]). Results: Active resulted greater power...
Two studies involving 122 handball players were conducted to assess the reliability, usefulness, and validity of a repeated shuttle-sprint jump ability (RSSJA) test. The test consisted 6x(2x12.5-m) sprints departing on 25 s, with countermovement performed during recovery between sprints.For reliability usefulness study, 14 well-trained male RSSJA 7 d apart. Reliability variables was assessed by typical error measurement, expressed as coefficient variation (CV). minimal changes likely be...
Long-term effects of training are important information for athletes, coaches, and scientists when associating changes in physiological indices with performance. Therefore, this study monitored aerobic anaerobic capacities performance a group elite cross-country skiers during full sport season. Thirteen men (age, 23 ± 2 years; height, 182 6 cm; body mass, 76 8 kg; V2 roller ski skating VO2max, 79.3 4.4 ml·kg·min or 6.0 0.5 L·min) were tested the early, middle, late preparation phase: June...
Background: To the authors’ knowledge, no study has investigated concurrent repeated, high-intensity (RHIA) and repeated-sprint activity (RSA) of intermittent team-sport competition. Purpose: In this study, they report on RSA elite women’s football addition, describe nature RHIA (eg, striding sprinting activities) that involve a high energy cost are associated with short (ie, ≤20 s) recovery periods. Methods: Thirteen women soccer players underwent video-based time–motion analysis 34...
Variations in rates of growth and development young football players can influence relationships among various fitness qualities. Purpose: To investigate the between repeated-sprint ability other fundamental qualities acceleration, agility, explosive leg power, aerobic conditioning through age groups U1 1 to U18 highly trained junior players. Methods: Male ( n = 119) across completed a assessment battery over two testing sessions. The first session consisted countermovement jumps without...
Team handball matches place diverse physical demands on players, which may result in fatigue and decreased activity levels. However, previous speed-based methods of quantifying player not be sensitive for capturing short-lasting team-handball-specific movements.To examine profiles a women's team individual profiles, using inertial measurement units.Match data were obtained from 1 national 9 international (N = 85 samples), the Catapult OptimEye S5. PlayerLoad/min was used as measure intensity...
Analyses of elite competitive performance provide useful information for research and practical applications.Here the authors analyze times cross-country skiers at international competitions (World Cup, World Championship, Olympics) in classical free styles women's men's distance sprint events, each with a total 410-569 athletes competing 1-44 races 15-25 venues from seasons 2002 to 2011.A linear mixed model race event provided estimates within-athlete race-to-race variability expressed as...
One of the challenges for sports scientists working in football is to balance needs routine fitness testing with daily fatigue and well-being monitoring best manage physical preparation players. In this commentary, authors examine contemporary issues identify ways improving value monitoring. A program must be well planned organized ensure that results are useful. Different tests can employed younger older rigorous approach analysis interpretation desirable, database management address both...
Game-based training drills are popular in team sports. This study compared two game-based conditions and official matches handball. Thirty-one women players wore inertial measurement units five sessions matches. In training, 3vs3 6vs6 were performed with a 5-min duration. PlayerLoad™ high-intensity events (HIEs; >2.5 m · s-1) extracted from the raw data. Data analysed using magnitude-based inferences reported effect sizes (ESs). min-1 all positions combined was 11.37 ± 0.49 (mean 90%...
Fast acceleration is an important performance factor in handball. In addition to traditional sprint training (TST), resisted-sprint (RST) a method often used improve acceleration. However, studies on RST show conflicting results, and underlying mechanisms have not been studied.To compare the effects of RST, by sled towing, against TST muscle architecture.Participants (n=18) were assigned either or completed 2 sessions per week (10 wk), their normal team training. Sprint tests 30 m)...
