NO AND N2O FLUXES FROM A BELGIAN FOREST AFFECTED BY ELEVATED NITROGEN DEPOSITION
Provedor de dados: 73
Autores: Boeckx,Pascal; Vervaet,Hilde; Cleemput,Oswald van.
Nitrous oxide (N2O) and nitric oxide (NO) are important atmospheric trace gases, and soils (including forest soils) are a substantial source of both gases. In forests subjected to elevated N deposition these emissions are considered as indirect emissions from agricultural N sources (mainly NH3) or combustion (e.g. NOx from traffic). However, knowledge about N2O and NO exchange between forests and the atmosphere is scarce. The aim of this study was to determine N2O and NO emission rates from a deciduous forest in Belgium, receiving a high N-deposition (ca. 40 kg N ha-1 yr-1). In April 2000, the NO emission from the forested location was 17.3 (± 1.2) and 17.05 (± 0.7) ng NO-N m-2 s-1, respectively, for the soil including the organic layer and the mineral...

Body Asymmetries in Young Male Road Cyclists
Provedor de dados: 77
Autores: Rauter,Samo; Vodicar,Janez; Simenko,Jozef.
An anthropometric analysis was conducted on 64 competitive young male road cyclists of different age categories (U17; U19; &amp;amp; U23 years of age). The purpose of the study is to find asymmetries between the left and right side of upper and lower limbs with the NX-16 (TC2) 3D body scanner, which includes measurement of left and right upper arm girth, elbow girth, forearm girth, wrist girth, thigh girth, knee girth, thigh length, calf girth, and shin length. Body composition was measured by the bioelectrical impedance machine InBody 720 (Biospace Ltd.). Results of body composition measurements of male road cyclists showed that U17 and U19 youth road cyclist differed statistically in five (from 11) paired variables, and the U23 age group differed...

Effect of the aerobic capacity on the validity of the anaerobic threshold for determination of the maximal lactate steady state in cycling
Provedor de dados: 56
Autores: Denadai,B.S.; Figueira,T.R.; Favaro,O.R.P.; Gonçalves,M.
The maximal lactate steady state (MLSS) is the highest blood lactate concentration that can be identified as maintaining a steady state during a prolonged submaximal constant workload. The objective of the present study was to analyze the influence of the aerobic capacity on the validity of anaerobic threshold (AT) to estimate the exercise intensity at MLSS (MLSS intensity) during cycling. Ten untrained males (UC) and 9 male endurance cyclists (EC) matched for age, weight and height performed one incremental maximal load test to determine AT and two to four 30-min constant submaximal load tests on a mechanically braked cycle ergometer to determine MLSS and MLSS intensity. AT was determined as the intensity corresponding to 3.5 mM blood lactate. MLSS...
