Knee varus position and motion have been correlated with increased medial knee loading during gait. The purpose of this study is to determine whether runners with excessive varus excursion (EVE) at the knee demonstrate frontal plane knee and hip kinetics that are different from those of runners with normal varus excursion (NVE). Twelve runners with EVE were compared with 12 NVE subjects using t...

Serum creatine kinase isoenzyme 2 concentrations (CK 2 mass) were measured in marathon runners during training and 1 and 2 days after a race and compared with values from 36 acute myocardial infarction (AMI) patients whose total CK and (or) CK 2 activities were similar to those of runners in the basal state. During training, runners had CK and CK 2 activities 53% and 43% above reference values,...

The aim of this studywas toinvestigate the effect ofrunning classification (sprint, middle, and long distance)and two distances on blood lactate (BLa), heart rate (HR), and rating of perceived exertion (RPE) Borg scale ratings in collegiate athletes. On different days, runners (n = 15) ran 400m and 1600m at a five min mile pace, followed by a two min 6mph jog, and a two min 3mph walk as part of...

The purpose of this study was to investigate possible factors which may account for differences in performance times within a closely-matched group (in terms of performance) of elite distance runners. The runners were training for competition in the 1984 Olympic Games in either the 5000 m or the 3000 m steeplechase events. Each runner's best performance time (BPT) was obtained and a stepwise re...

Recreational long-distance runners’ exercising levels often considerably exceed those necessary for keeping healthy. As their running careers unfold, many runners become inspired not so much by fitness and health but other corollaries of running, such as capacity to endure high pain exhaustion or novel bodily experiences. I show in the ethnographic example Estonian runners, a “low-resolution” e...

A high drop-out rate prior to the running of a Marathon reduces its value as a spectacle and needlessly causes rejection and antagonism amongst potential runners. This research investigates reasons for pre-race drop-out in the 1983 Glasgow Marathon, and finds that a major cause was injury or illness during training, with a motivational difference existing between runners and non-runners.

The effects of air temperature, relative and specific humidity, wind speed, solar shortwave radiation, thermal longwave radiation, and rain on the performance of participants in the annual Stockholm Marathon from 1980 to 2008 were analysed statistically. The objective was to validate and extend previous studies by including data on finishing times of slower male and female runners and on the pe...

BACKGROUND Concern exists that certain types of exercise, particularly vigorous activity, may increase physical disability among older individuals. We investigated the prevalence of, and risk factors for, physical disability in active older persons (runners), and examined factors influencing the progression of physical disability with age. METHODS Physical disability, measured using the Healt...

AIMS To quantify the prevalence of coronary artery calcification (CAC) in relation to cardiovascular risk factors in marathon runners, and to study its role for myocardial damage and coronary events. METHODS AND RESULTS In 108 apparently healthy male marathon runners aged >or=50 years, with >or=5 marathon competitions during the previous three years, the running history, Framingham risk score...

A questionnaire was given to all participants of the Wonderful Copenhagen Marathon 1986 regarding demographic information, health, training, previous injuries and methods used to prevent these. A total load of 2158 Danish runners participated and 1426 (68 per cent) replied. Fifty per cent of the runners were training 30-60 km per week and 25 per cent more than 60 km per week. Forty-one per cent...
