Kernel Density Estimation: A Novel Tool for Visualising Training Intensity Distribution in Biathlon
PurposeThis study introduces two-dimensional (2D) Kernel Density Estimation (KDE) plots as a novel tool for visualising Training Intensity Distribution (TID) in biathlon. The goal was to assess how KDE plots, alongside traditional training metrics, might provide a more detailed understanding of heart rate (HR) intensity patterns, aiding in the evaluation of training quality and compliance.MethodsFifteen elite-level youth biathletes from two natio…
Reliability agreement in foul and penalty judgements between officials in the Swedish hockey league
Introduction Officials are essential in terms of player safety and injury prevention, especially in contact team sports such as ice hockey, where numerous fast pace and high force contacts occur. If against the rules, these collisions can result in penalties. However, there is limited literature on the inter-rater reliability of the officials’ decisions. Hence, the purpose was to investigate the theoretical reliability agreement between professio…
Discrepancies in internal and external training load measurements during low-intensity biathlon training
The study's findings indicated that there were no notable differences in internal training load (TRIMP) when comparing various training intensities and modes. However, the type of training had a significant impact on A v F N e t , especially leading to a decrease during COMB sessions under LIT conditions. Incorporating an external load metric could offer a fresh approach when prescribing and evaluating training, providing deeper insights into the…
Quantity of within-sport distance variety – what can pool swimmers and track runners learn from each other
Objective To determine the relationship between success at peak performance age and quantity of within-sport distance variety and compare the dose-time-effect between swimming and track running by determining probability of becoming an international-class female athlete based on the number of different race distances the athletes compete in each year throughout their development process. Methods Race times of female Tier 2 to Tier 5 freestyle poo…
New insights from Norwegian and Swedish sports coaches' employment, practices, and beliefs during the first Covid-19 restriction period
Overall, this study showed the imposed movement restrictions had several negative consequences for the employment and work practices of sports coaches in Norway and Sweden. However, it also highlighted that coaches were able to adapt their work practices to the constraints and were able to maintain relationships with their athletes. The consequences raised in this paper can act as a guide during possible future lockdowns
How Does the Starting Order in the First and Second Run Affect the Final Rank in the FIS World Cup Giant Slalom
The aim of this study was to determine the impact of runs 1 and 2 on overall rank in Giant Slalom. Data from 15 seasons (2005/2006–2019/2020) including and unique starts for women ( n = 2,294) and men ( n = 2,328) were analyzed. Skiers were grouped based on final ranks 1–3 (G3), 4–10 (G10), and 11–20 (G20) and separately analyzed for women and men. A Wilcoxon-signed rank test was used for comparisons between runs 1 and 2, while a multi-nominal lo…
The Effect of Rifle Carriage on the Physiological and Accelerometer Responses During Biathlon Skiing
Purpose Investigate the effect of biathlon rifle carriage on physiological and accelerometer-derived responses during biathlon skiing. Methods Twenty-eight biathletes (11F, 17M) completed two XC skiing time-trials (~2,300 m), once with and once without the biathlon rifle, with concurrent measurements of HR, skiing speed and accelerations recorded from three triaxial accelerometers attached at the Upper-spine, Lower-spine and Pelvis. Exercise inte…
The Determinants of Performance in Biathlon World Cup Sprint and Individual Competitions
PurposeThe present study aimed to determine the association of skiing speed (SS), range time (RT), and the number of missed targets (MT) with rank in sprint and individual biathlon competitions.MethodsData were collected from the International Biathlon Union's database for 17 seasons (2002/2003-2018/2019). Furthermore, the biathletes were divided into three rank groups (G3, rank 1-3; G10, rank 4-10; and G20, rank 11-20). Multinominal regression w…
The Effect of Autoregulated Flywheel and Traditional Strength Training on Training Load Progression and Motor Skill Performance in Youth Athletes
FRT resulted in similar load progression and motor skill development in youth athletes as TST, but the perceived exertion was less. Autoregulation is a practical method for adjusting training load during FRT and should be considered as an alternative to autoregulated TST
Runners Adapt Different Lower-Limb Movement Patterns With Respect to Different Speeds and Downhill Slopes
The aim of this study was to investigate the influence of slope and speed on lower-limb kinematics and energy cost of running. Six well-trained runners (VO 2max 72 ± 6 mL·kg −1 ·min −1 ) were recruited for the study and performed (1) VO 2max and energy cost tests and (2) an experimental running protocol at two speeds, 12 km·h −1 and a speed corresponding to 80% of VO 2max (V80, 15.8 ± 1.3 km·h −1 ) on three different slopes (0°, −5°, and −10°), t…
Metabolic Demands, Center of Mass Movement and Fractional Utilization of V ̇O2max in Elite Adolescent Tennis Players During On-Court Drills
The aim of the study was to investigate the exercise intensity and energy expenditure during four types of on-court tennis drills. Five female and five male tennis players participated in the study (age: 17 ± 2 years; V ∙ O 2 m a x : 54 ± 6 ml·kg-1·min-1). Anthropometric measures were taken for each player and, on separate days, each player performed (i) treadmill running to determine V ∙ O 2 m a x and (ii) four different tennis drills (Drill1-4)…
