In an effort to seek further understanding of lower limb muscle function in the rowing movement, an electromyographic analysis was undertaken of rowers rowing on a Gjessing ergometer. A strain gauged transducer was inserted in the ergometer linkage between handle and flywheel to detect pulling force. Electrodes were placed on the following lower limb muscles: gluteus maximus, biceps femoris, re...

Background and Study Aim. The aim of this study is to verify the X-method for determining second anaerobic threshold in rowers.Material Methods. Twelve male athletes from national rowing team Bulgaria were tested. Participants performed a one-time graded incremental exercise test exhaustion on ergometer. workload conducted ergometer system Concept 2, spirometry Clark C5. We obtained ventilatory...

Fluctuating asymmetry (FA) can be defined as an organism's deviation from perfect bilateral symmetry. FA has been of interest to evolutionary biologists as it may be indicative of the ability of an individual to express its genotype in a stable manner. Asymmetry has been shown to correlate with success in both intra- and inter-sexual selection in various species, including humans. A growing bod...

Background: Rowing movements can be simulated using specialized ergometers; the method can be used both for training and indoor assessment of body movements within controlled conditions. Purpose: To perform a three-dimensional quantitative analysis of body movements during ergometer rowing, and to examine if there is a relationship between anthropometry and rowing kinematics. Study Design: Desc...

A real-time recording setup combining exhaled breath volatile organic compound (VOC) measurements by proton transfer reaction-mass spectrometry (PTR-MS) with hemodynamic and respiratory data is presented. Continuous automatic sampling of exhaled breath is implemented on the basis of measured respiratory flow: a flow-controlled shutter mechanism guarantees that only end-tidal exhalation segments...

Blood hypercoagulability or thrombogenicity can be one of the main causes of the cardiovascular diseases in young population without traditional pathologic risk factors such as diabetes mellitus, hypertension or hyperlipidemia. The effect of aerobic exercise on coagulation and fibrinolysis has been studied extensively Regarding to the effectivness of resistance exercises to increase functional...
