Abstract

Objective: To investigate the association of anthropometric
parameters to race performance in ultra-endurance runners in a multistage ultra-endurance run.
Design: Descriptive field study.
Setting: The Deutschlandlauf 2006 race in Germany, where athletes had to run 1200 km within 17 consecutive days. There were no interventions.
Subjects: In total, there were 19 male Caucasian ultraendurancerunners (mean (SD) 46.2 (9.6) years, 71.8 (5.2) kg, 179 (6) cm, BMI 22.5 (1.9) kg/m2). Main outcome measurements: Determination of body mass, body height, length of lower limbs, skin-fold thicknesses, circumference of limbs, body mass index (BMI), percentage skeletal muscle mass (%SM), and percentage body fat (%BF) in 19 successful finishers in order to correlate anthropometric parameters with running performance.
Results: A significant association of upper arm circumference with the total running time was found (p,0.05,
r2=0.26). No significant association was found with the
directly measured anthropometric properties body height, body mass, average skin-fold thickness and the circumference
of thigh and calf (p.0.05). Furthermore, no significant association was observed between the running time and the calculated parameters BMI, %BF, and %SM (p.0.05).
Conclusions: In an ultra-endurance run over 1200 km within 17 consecutive days, circumference of the upper arm was the only factor associated with performance in well-experienced ultra-endurance runners. Body mass, BMI, body height, length of limbs, skin-fold thicknesses, circumference of limbs and the calculated percentage body composition of skeletal muscle mass and body fat showed no association with running performance.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
