Anthropometric Profile of Male Amateur vs Professional Formula Windsurfs Competing at the 2007 European Championship

Anthropometric Profile of Male Amateur vs Professional Formula Windsurfs Competing at the 2007 European Championship This study aimed to describe the current anthropometric profile of Formula Windsurf competitors during the 2007 European Championships and establish a set of reference values useful for future investigations on player selection, talent identification, and training programme development. Fourty-five male participants (mean age 30±9.77 years; body height 182.04±6.3 cm; body mass 81.67±7.35 kg) were selected for the anthropometric profile, including 15 which the International Windsurf Association had defined as professionals. The anthropometric profiles included measurements of skinfolds, segment lengths, breadths, and girths. Somatotype measurements were also calculated into the equation. The male professional windsurfers had larger length, breadth, and girth measurements than their amateur counterparts. The three somatotype components showed that both groups were predominantly mesomorphic, but the professionals were more ectomorphic than endomorphic, whereas the amateurs were slightly more endomorphic than ectomorphic. The descriptive analysis of the anthropometric data provide relevant information concerning the morphological indicators of competitive success in this sporting discipline.

Effects of seawater ingestion on lactate response to exercise in runners

The aim of this study was to examine the effect of microfiltered and sterilized seawater ingestion on running performance in a hot environment. This cross-over, double-blind randomized trial included 12 experienced male runners. The subjects randomly consumed seawater (SW) or pure water (placebo) in an equivalent amount of 50 ml five minutes prior to running at 40% of their VO2 max for 95.0 ± 18.5 min, at 30°C, until they lost 3% of body weight. Every 20 minutes, a measurement of their body weight was taken and a blood lactate analysis was performed. The concentration of lactate was significantly lower after the running exercise in the SW condition compared to placebo. The results of this study provide evidence supporting the ergogenic effects of microfiltered and sterilized seawater ingestion on running performance and lactate production.
