BACKGROUND Alpine skiing and snowboarding are popular winter activities worldwide, enjoyed by participants of all ages and skill levels. There is some evidence that the incidence of traumatic brain injury (TBI) and spinal cord injury (SCI) in these activities may be increasing. These injuries can cause death or severe debilitation, both physically and emotionally, and also result in enormous fi...

The purpose of this study was to quantify and contrast the instantaneous segmental and total body energy patterns of rowing a single scull racing shell with rowing a Gjessing (Norway) rowing ergometer (RE), and to contrast energy savings through exchanges of mechanical energy among segments and conversions of energy within segments. Four scullers, two male and two female, were filmed at three s...

PURPOSE The Concept II model C (IIC) rowing ergometer was replaced by the Concept II model D (IID), but the design modifications of the updated ergometer might alter resistance characteristics and rowing technique, thereby potentially influencing ergometer test results. This study evaluated the physiological response to rowing on the IIC and IID ergometers during a submaximal progressive increm...

The aim of this study was to establish the relationship between selected physiological variables of rowers and rowing performance as determined by a 2000 m time-trial on a Concept II Model B rowing ergometer. The participants were 13 male club standard oarsmen. Their mean (+/- s) age, body mass and height were 19.9+/-0.6 years, 73.1+/-6.6 kg and 180.5+/-4.6 cm respectively. The participants wer...

In this study, we evaluated the extent to which 2000-m rowing ergometer performance times predicted final rankings at the World Rowing Championships in a sample of 638 rowers of both sexes and body-mass classifications (i.e., open-category and lightweight rowers). Rowing ergometer performance times were examined using a questionnaire, and in 17 of 23 events they were positively correlated (P < ...

geographical position, topographic conditions and climatic variety have caused the ‎province of zanjan to be known as the province of four seasons. its unique ‎ecological conditions, forest and pasture coverage, numerous water resources, ‎wildlife, several hunting zones, protected areas, caves, waterfalls, springs and tens of ‎other beautiful unique landscapes have caused this province ...

Background Research shows that the prevalence of lower back (LBP) pain is high among rowers [1,2]. Previous methods of data collection on LBP in the Australia Rowing Team (ART) do not allow for comparison against other rowing populations. The purpose of this study was to collect the current prevalence of LBP across senior elite Australian rowers at one point in time, using methods comparable to...

In recent years, water skiing is gaining more and popularity in Ukraine the world. Despite fact that not an Olympic sport, it very popular. Water a sport entertainment at same time. International competitions held - European Championships World Championships. The stage of initial training falls on age 7-9 years. At this age, children’s aptitudes abilities are revealed, their health strengthened...

This paper describes an experiment involving a professional downhill skier equipped with GPS and MEMS-IMU, as well as a triad of magnetometers and a tactical-grade inertial unit. The experiment illustrates the navigation performance of GPS/MEMS integration compared to high-quality GPS/INS integration challenged by the environmental conditions and dynamics of ski-racing. The MEMS sensors’ output...
