Running performance not anthropometric factors is associated with race success in a Triple Iron Triathlon


Knechtle, B; Kohler, G (2009). Running performance not anthropometric factors is associated with race success in a Triple Iron Triathlon. British Journal of Sports Medicine, 43(6):437-441.

Abstract

OBJECTIVES: To investigate the influence of anthropometric parameters on race performance in ultra-endurance triathletes DESIGN: Descriptive field study. SETTING: The Triple Iron Triathlon Germany 2006 in Lensahn over 11.6 km swimming, 540 km cycling and 126.6 km running. SUBJECTS: 17 male Caucasian triathletes (mean +/- SD, 39.2 +/- 7.5 years, 80.7 +/- 8.9 kg, 178 +/- 5 cm, BMI 25.4 +/- 2.4 kg/m2). INTERVENTIONS: None. Main Outcome Measurements: Determination of body mass, body height, skin fold thicknesses, circumferences of extremities as well as calculation of body mass index (BMI), skeletal muscle mass (SM), percent SM (%SM) and percent body fat (%BF) in order to correlate measured and calculated anthropometric parameters with race performance. RESULTS: Body mass, body height, skin fold thicknesses, circumferences of extremities, BMI, %SM and %BF had no effect (p>0.05) on race performance The squared correlation coefficient between the race time and the anthropometric properties limb circumferences, BMI, %SM and %BF was always lower than 0.03. The best correlation was shown between running time and total race time (r2=0.87) as well as cycling time and total race time (r2=0.62). The lowest correlation was shown between swimming time and total race time (r2=0.04). CONCLUSIONS: There is no association of anthropometric parameters with race performance in ultra-endurance triathletes. Running performance before cycling performance seems to be the most important factor in order to be successful in a Triple Iron Triathlon. Swimming performance seems to be of low importance.

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.
