Time is a primary classification parameter in alpine skiing competitions. In this study a measuring procedure and methodology were developed how to accurately retrieve gate-to-gate times using a high-end navigation system (GNSS). This allows a direct insight into intercourse or gate-to-gate time difference.

Despite the fact that the athletes in alpine skiing are classified according to time where the differences among competitors in can be in fractions of a second, in short sections (e.g., 1 to 4 gates) very larger differences can occur. It turns out that the time for determining the quality of skiing in a short section is not a good parameter because it is very strongly related to the entrance velocity, i.e. skiing before the inspected section. Therefore, we developed a new integral energy parameter: change in specific mechanical energy normalized by the entrance velocity, which directly defines the quality of skiing on a short section.

On the market is a huge number of manufacturers who produce high tech technology and who advertise high technical data specifications of their products. For the research on children comuting habits we wanted to use TrackstickTM super GPS, which promised high frequency and high accuracy in subject position determination. Technology which was promising a lot (according to manufacturers technical data) was found as completely non adequate technology, which is not good for research use. The most important conclusion is that manufacturers tehnical data should be always tested from the point of validity and reliability and not just belive manufacturers what they promise.

The monography presents the development and application of certain state-of-the-art biomechanical measurement procedures in athlete training. The following diagnostic procedures have been developed in the training process of an athlete: 3D kinematics, dynamics, EMG, measurement of sprint velocity and thermovision.

Aim of the study was to determine the effect of eight weeks endurance training on iron status, some indicators of inflammation and hormone hepcidine in women. The sample included 18 recreational runners. Six laboratory samples were taken at the beginning of the experiment, after the two three weeks intensive training periods, after each week of rest and a week after the marathon. The results of our study confirm that the eight-week exercise has negative effect on iron balance in women. Hepcidine was significantly lower after the first three weeks of cycle training and at the end of the study. With exclusion of inflammation, we find that the change in the hepcidine value is more in conjunction with the control of iron homeostasis in the body as with the exercise-induced inflammation.
