The purpose of the research was the evaluation of efficiency of anaerobic ability (power), anaerobic endurance, anaerobic fatigue and the restitution of the pulse rate of alpine skiing students through the slalom simulator. In addition, the aim of the research was the correlation of the special tests of alpine skiing on dry ground (octagon test) and in snow (triangle test and slalom test) with the target of determining ability levels.

Purpose:The purpose of the present research was the study and evaluation of the theodolite's (topographic speedometer) use in tracing a path in slalom racing on snow conditions with 58 gates and also to record the optimal method of tracing a slalom route in relation to: a) the "velocity" of the race track (degree of difficulty of slalom), b) safety of tracing the slalom route. Material:This research was based on methodology and measurements of a race track in giant slalom with 35 gates in the ski resort "3-5 Pigadia" of Naoussa -Greece. The topographic speedometer was fixed in place at the start of the route. From this point, measurements were taken, for the placement of all 58 gates throughout the route. The measurement was taken using the pole-prism, placed in each interior gate turn, at which the theodolite was aimed. With the help of topographic speedometer the following geometrical parameters have been registered: distance between the gates (Δs), altitude difference of points (Δh) with an accuracy up to 1cm, terrain slope (θ), gate angular deviation (δ) with an accuracy of up to 1 minute of the angle (°). This allows the creation of the top-view, side-view (profile) and three-dimensional aspect of the track, under race conditions on snow and not on dry ground. Results:The correlation coefficient (r) between the geometry factor (V.gs) and average the above geometry parameters had the following respective values: V.gs -Ms = 0,15, V.gs -Mθ = -0,52, V.gs -Mδ = -0,29 for 58 gates on a level of statistical significance of p < 0,05. Conclusions:The first part comprised of 10 gates was the "fastest" (V.gs = 18 degrees) of the total slalom route in Naoussa with 58 gates (V.gs = 14 degrees). With the above criteria, slaloms will be compared to each other and will be evaluated against age and safety.

Purpose:The purpose of this research was to diagnose the physical abilities such as speed, strength, agility and endurance of alpine skiers and footballers through the same country tests. Also, the purpose was to compare the performance and test results of the above tested against one another. Material:The sample of 58 individuals came from two groups of men of different sports: skiing (n = 29) aged 18-26 (20.97 ± 2.08 years) and football (n = 29) aged 18-25 (21, 28 ± 1.56 years), while the level in each group was the advanced and the beginner respectively. Until the trials, the ski and football teams had a training program exercising physical abilities and skills three days a week for the specialties and one day a week the select skiing session and the compulsory football session according to the curriculum. In order to diagnose and compare the physical abilities of ski students and football students, the following four tests of Alpine skiing on dry ground were used after the ski season on this day in April 2014: A) Route speed test (route 20m with flight start). B) Explosive power tests of the lower limbs (eightfold with alternating tossing of feet). C) Agility Tests (Slalom's track on a "folder" 5m x 5m). D) Anaerobic test (jumping obstacle 20cm height for 60sec). Results:In the skiing specialty we have a great correlation between speed tests and other physical abilities and agility with endurance (r = -0,72). In football specialty there was a great correlation between speed and power tests (r = -0.65) and agility with the power (r = -0.69). In optional skiing, we have a moderate correlation between the tests, while in the "A" year football students the correlation between speed and strength (r = -0.81) is distinguished. Conclusions:It is noteworthy that the students of the first year of football as well as the specialists do not have as good results in endurance as compared to the students of the skiing, even though the football game lasts 90 minutes compared to Alpine skiing 1-2 minutes.
