Lower Leg Length is Associated with Running Economy in High Level Caucasian Distance Runners

of three ( Kong and de Heer, 2008 ) or six ( Legaz and Eston, 2005 ) skinfolds have been related to distance running performance. However, there is equivocal data about how running economy (RE) is related to anthropometric and/or body composition variables. Runners with proportionally lower body mass concentrated in the extremities, particularly in the legs, would perform less work moving their body segments during running, if all other factors are unchanged ( Myers and Steudel, 1985 ). Therefore, leg mass and the distribution of leg mass might be important

10 km running performance predicted by a multiple linear regression model with allometrically adjusted variables

trained and untrained individuals ( Conley and Krahenbuhl, 1980 ; Noakes et al., 1990 ; Stratton et al., 2009 ). A factor which may be related to poor predictive power of VO 2max is the difference in body dimensions ( Chamari et al., 2005 ; Eisenmann et al., 2001 ; Vanderburgh and Laubach, 2008 ), as studies have often not considered variations in body mass when measuring VO 2max . Other physiological variables, such as running economy (RE), defined as the energy demand for a given velocity of submaximal running ( Saunders et al., 2004 ), has been associated with

Intra-Subject Variability of 5 Km Time Trial Performance Completed by Competitive Trained Runners

., 1992; Winter et al., 2007 ). Evidence suggests strong correlations between V . $\it V^{.}$ O 2max and 5 km performance (males, r = −0.85, females, r = −0.80; Ramsbottom et al., 1987 ). Other performance traits associated with 5 km distance include a high lactate threshold ( Noakes et al., 1990 ) and efficient running economy ( Conley and Krahenbuhl, 1980 ). Subsequently, when compared with greater running distances, 5 km running trials may provide a more maximal physiological measure of running performance, and as such, present a useful outcome measure when

A Rapidly-Incremented Tethered-Swimming Test for Defining Domain-Specific Training Zones

., 2004 ; Yoon et al., 2007 ). This has resonance for swimming because the incremental protocol that is typically employed ( Fernandes et al., 2003 , 2011 ; Ribeiro et al., 2015 ) comprises 7-8 steps and, therefore, overall test duration can exceed 12 minutes. Despite its non-steady-state nature, the smooth-ramp test also reveals a V . $\mathop{\text V}\limits^. $ O 2 /work-rate slope that serves as a measure of exercise economy ( Whipp et al., 1981 ). It is generally believed that improving V . $\mathop{\text V}\limits^. $ O 2max , V . $\mathop

Triathlon wetsuit removal strategy: physiological cost of running with a wetsuit

exiting the water or waiting until reaching the bike. Since there are no data on the physiological cost of triathlon transition, our approach was to determine the running economy while not wearing a wetsuit, wearing the wetsuit half way down, wearing the wetsuit fully up and carrying the wetsuit. Another experimental approach would be to measure VO 2 while an athlete exits the water and transitions to the bike. However, it was important to first know running economy while running at a steady state before including energetic cost of taking the wetsuit off. It seems

Perceived work ability index of public service employees in relation to ageing and gender: A comparison in three European countries

-olds ( 12 ). Work ability decreases with age even among the healthy ( 13 ). Work ability significantly decreased with age among the women. Also, the ageing trend of WAI is different, depending on the sector of the economy. Work ability seems to be lower in farming and agriculture, the wood industry, the metal industry and transport, as well as in social services and in some countries among teachers (public sector) ( 14 ). The present study therefore aims at examining perception of work ability and its dimensions of public service employees aged 55 and older and gender
