increased metabolic activity in muscle secondary to excessive muscle activity during the uptake phase and shortly before fdg injection is a known phenomenon. we present fdg pet/ct findings in a young male, known case of carcinoma maxilla his scan showed diffuse increased metabolic activity in multiple skeletal muscle groups. there was history of unaccustomed, strenuous sports activity of skiing...

The aims of this study were to examine two ski simulators, Skimagic and Skier's Edge, and to evaluate their efficacy as functional training devices for skiers. Vertical ground reaction forces, knee flexion angle kinematics and muscles activity were recorded on these devices and compared with those measured in similar condition while skiing on snow. Five ski instructors performed three randomize...

Introduction: Over the years, advances in alpine ski equipment such as helmets, bindings, skis and boots have resulted risk reduction, remodelling of injury patterns mechanisms. Skiers’ injuries are currently about 1 to 5 per 1000 days spent snow athlete. The most common area is knee, especially ACL MCL. Purpose work: purpose work analysis literature on mechanism knee ligaments potential preven...

Abstract Understanding how postural changes in alpine skiing affect the overall aerodynamic drag is highly important for enhancing performance. Although arm configuration of athlete can have a significant impact on force, this effect currently less understood. The purpose investigation was to examine arms an skier influence drag. Experiments were performed wind tunnel male and female athlete, c...

Injuries among children during sporting activities are common. This study is a one year study including children between five and fourteen years of age who sustained their injuries during sporting activities and were treated at Trondheim Regional and University Hospital. Sport accidents account for 27 per cent of all childhood accidents in this age group. Fifty-three per cent of the injured wer...

While some work has gone into developing specific learning environments, little has gone into clarifying the general issues that affect the acquisition of a complex skill, especially in a naturalistic setting. A study was made of an extremely complex skill, skiing, to determine why it has become so easy to learn. The goal was to analyze the features of a highly successful learning environment i...

The aim of this study was to determine whether participating in a cross-country skiing stage race (Tour de Ski; TDS) affects subsequent illness incidence, training, and race performance. Self-reported training and illness data from 44 male and female elite cross-country skiers were included. In total, 127 years of data were collected (2-3 seasons per athlete). Illness incidence, training load, ...

The practice of sliding across the snow with supportive implements may date back as far as 5000 years ago when early hunters and fisherman used crude animal tusks to transverse snow. Precursors of modern skis have been found in Scandinavia and Siberia and have been dated back to 2000 BC. However, the first written record of skis is attributed to Chinese historical accounts dating to 600 AD. In ...
