Bootstrapping is a method for generating the uncertainties (confidence limits and probabilities) in the true value of a statistic from a study of a sample. Bootstrapping is useful when the usual modeling methods based on assumptions about sampling distributions are untrustworthy or unavailable, for example when modeling the optimum effect ...

Modern laboratory testing of endurance athletes has evolved over six decades, beginning with the establishment of maximal oxygen consumption (VO2max) as a valid and repeatable measure of aerobic capacity. While A.V. Hill introduced the concept of VO2max already in the 1920s, it was Henry Taylor, Per-Olof Astrand and Bengt Saltin ...

Analysis of player actions in team sports can provide useful predictors of game outcome, but there have been few published analyses of games of American football. In this study we have analyzed publically available data from the American National Football League (NFL). Methods: The data consisted of over 100 variables ...
Buchheit, Martin - - 2011
The most positive aspects of this quadrennial conference were the productive mix of the various football codes and open access to videos of all 41 invited lectures. Talent Development: relative age effect, developing young players, sprint performance, draft camps. Training & Monitoring: load management, heart rate, perceived exertion, sport-science support, ...

When a subject characteristic substantially modifies the effect of a treatment or other intervention in a controlled trial, precision of the estimate of the treatment effect is improved by allocating subjects to control and treatment groups in a manner aimed at minimizing the differences between population and group means of ...

The utility of a practical or other measure can be assessed in a validity study, in which values of the measure are compared with those of a criterion measure taken concurrently in a sample of subjects. A scatterplot of criterion vs practical values provides a qualitative assessment of non-linearity, random ...

Effects are relationships between variables. The magnitude of an effect has an essential role in sample-size estimation, statistical inference, and clinical or practical decisions about utility of the effect. Virtually every effect in research, clinical and practical settings arises from a linear model, an equation in which a dependent variable ...

The biggest gain this year in the impact factor (mean cites per article per year) for journals specializing in exercise or sport science or medicine was that of the Journal of Strength and Conditioning Research, now on 1.5 (up by 88% from last year's 0.8). Other journals with gains of ...
Hopkins, Will - - 2010
This conference was noteworthy for wonderful food in an exotic castle of mirrors. Two of the best studies on sport performance were in basketball: a controlled trial to improve free throws and an analysis of offensive play. A series of case studies of technology for US athletes was also inspiring. ...
Hopkins, Will - - 2010
This quadrennial conference was hosted in 2010 by the Norwegian Sport University, NIH. Amongst the best performance-related presentations were a case study of a change in butterfly kicking style and large-scale longitudinal studies of talent identification and overtraining in swimmers. Novel Technologies and Analyses: pressure across the hand, active drag, ...
Hopkins, Will - - 2010
The annual conference of the American College of Sports Medicine was noteworthy for the domination by sports nutrition research. This year's winning strategies are chocolate milk for recovery and sustained-release [beta]-alanine for high-intensity events. Acute Effects: warm-ups, acupuncture, Energicer, contrast therapy, garments, gliding in swimming, pacing. Nutrition: quercetin and other ...

The list of sports in the Winter Olympics has expanded dramatically in recent years, resulting in more medals for nations specializing in winter sports. Canada has emerged as a major Winter Olympic power and is a medal contender in virtually all sports. Smaller winter nations like Norway win most of ...
Bonetti, Darrell - - 2010
Isotonic sports drinks containing carbohydrate and electrolytes are often consumed for endurance performance, but hypotonic drinks may be superior. The purpose of this study was to compare effects on performance and related physiology of a new sports drink, Mizone Rapid (hypotonic; containing carbohydrate and electrolytes) with three other drinks: Mizone ...
Hopkins, Will - - 2009
Amongst journals specializing in sport and exercise, the gold medal for the highest impact factor this year went for the first time to American Journal of Sports Medicine (3.6). Making a substantial improvement since last year, Medicine and Science in Sports and Exercise was second equal with Exercise and Immunology ...

A governor in the brain that limits drive to muscles would explain why we can't normally exercise to the point of collapse, but better explanations include self-limiting mechanisms to protect the periphery and intolerable sensations of heat and breathlessness to protect the brain. Moreover, it is reasonably clear that cardiac ...

This conference was noteworthy for the focus on sport and exercise science and the youthful enthusiasm of the attendees. Don't miss the 2010 meeting in Turkey. Acute Effects: choking in penalty shoot-outs; benefits of pre-cooling, sodium loading, post-activation potentiation, and warm-ups; no benefit of compression garments. Coaching: coach-captain relationship, athlete ...

Endurance training involves manipulation of intensity, duration, and frequency of training sessions. The relative impact of short, high-intensity training versus longer, slower distance training has been studied and debated for decades among athletes, coaches, and scientists. Currently, the popularity pendulum has swung towards high-intensity interval training. Many fitness experts, as ...

Filtering raw biomechanical data to remove noise is a key first step that must be performed prior to further biomechanical analysis. Raw biomechanical data are usually filtered to remove noise above a specified cutoff frequency, a process known as "low pass filtering". The concept of frequency content within a signal ...
