Abstract Athletic records represent the best results in a given discipline, thus improving monotonically with time. As has already been shown, this should not be taken as an indication that the athletes' capabilities keep improving. In other words, a new record is not noteworthy just because it is a new record, instead it is necessary to assess by how much the record has improved. In this paper we derive formulae that can be used to show that athletic records continue to improve with time, even… 

Limit to Improvement in Running and Swimming

The world records of 61 sport events in running and swimming through the last hundred years have been analysed and the time to limit projection made is likely to be altered by the future rule changes to be made by the international federations.

Internationalization, competitiveness and performance in athletics (1984–2006)

This study examines whether a process of internationalization has affected the level of athletic performance amongst high-level athletes competing on the world stage. Top 100 International

Record books do not capture population trends in horn length of bighorn sheep

Record-book entries and data from male bighorn sheep harvested under a minimum-curl regulation could detect temporal trends in horn length but severely underestimated increases and did not detect declines, suggesting that they should not be used to monitor population trends.

The Records

World record setting has long attracted public interest and scientific investigation. Extremal records summarize the limits of the space explored by a process, and the historical progression of a

Records in stochastic processes—theory and applications

This review is an attempt to summarize and evaluate the progress that was made in the field of record statistics throughout the last years.

Record occurrence and record values in daily and monthly temperatures

We analyze the occurrence and the values of record-breaking temperatures in daily and monthly temperature observations. Our aim is to better understand and quantify the statistics of temperature

Modeling World Record Predictions in Track Events

The estimation of best possible running track events is considered, and it is demonstrated there can be substantial variance is best estimates unlike other literature which offers up best times.

Persistence of random walk records

We study records generated by Brownian particles in one dimension. Specifically, we investigate an ordinary random walk and define the record as the maximal position of the walk. We compare the

Exact and asymptotic properties of δ-records in the linear drift model

The study of records in the linear drift model (LDM) has attracted much attention recently due to applications in several fields. In the present paper we study δ-records in the LDM, defined as

Models for comparing athletic performances

A parametric form is suggested which can be useful for characterizing the change in performance with distance and described jointly the decrease in several world records over several years and so to predict lower bounds on these records.

Sports statistics: Trends and random fluctuations in athletics

It is found that only 4 out of 22 disciplines have shown a systematic improvement, and that annual best results worldwide show saturation in some disciplines.

Statistics for Exceptional Athletics Records

Robinson and Tawn (1995) analysed data from 1972 to 1992 in the women's 1500 m and 3000 m running events, with a view to establishing whether the remarkable performances achieved by Chinese athletes

Statistics for Exceptional Athletics Records

Analytical methods based on extreme value techniques are applied to the analysis of data from the women's 3000 m track event, where it is found that a recently broken record shows signs of being inconsistent with previous performances.

Human performance: Scaling in athletic world records

Running records are analyzed and it is shown that the mean speed as a function of race time can be described by two scaling laws that have a breakpoint at about 150–170 seconds, interpreted as being the transition time between anaerobic and aerobic energy expenditure by athletes.

Extremal analysis of short series with outliers: sea‐levels and athletics records

The analysis of extreme values is often required from short series which are biasedly sampled or contain outliers. Data for sea‐levels at two UK east coast sites and data on athletics records for

Abstract:In a recent paper, Mizera and Horváth computed the effects of environmental factors on shot put and hammer throw ranges [J. Biomech. 35, (2002) 785-796]. They found that the geographic

Based on the described correlation method, real‐time fMRI experiments using visual stimulation paradigms have been performed successfully on a clinical MR scanner, which was linked to an external workstation for image analysis.

How Surprising is a New Record?

This article presents a novel and simple way to assess the exceptionality of a new record. We illustrate the use of this measure in two examples, one from archaeology and the other from athletics.
