Abstract
Background & Study Aim: Alpine skiing is a physical activity that stimulates (develops and maintains) primarily coordination skills, mainly the balance of the body, and also ability to kinaesthetic differentiation. An innovative method of measuring the ability to optimally use the muscle strength (AOUMS) of lower limbs is recommended. The purpose of this study is to answer the question whether students after the alpine skiing course will improve ability to optimally use the muscle strength of lower limbs.
Material & Methods: The study included a group of eleven students (5 women and 6 men) who participated in an alpine skiing course were examined. The basic skiing course lasted 10 days: 7 teaching hours (45 minutes each) a day. The method used was this recommended by Kalina (2021): ‘diagnostic exercise systems’. Diagnosis of lower limb AOUMS (non-apparatus version): long jump from standing posture. Patterns of force use in diagnosing lower limbs were used (the first exercise with eyes open, the second exercise eyes covered) and then alternated: 50%, 25%, 75%, 50% , 35%, 85%. The series of six exercises ended with three trials with open eyes, each at 100% (the farthest jump was the frame of reference for measuring the conformity of each score to the model expressed in %). The subjects had no prior knowledge of the methods. Body composition was measured device Tanita 525N.
Results: The fourth-ranked student before the alpine skiing course Index AOUMS for lower limbs was 16.11+, and under the influence of specific measures and new motor experiences related to learning skiing, it decreased to 5.72+&− (she became the leader of the results at the end of the course) .The phenomenon turned out to be bipolar: the leader from before the course (10.55+) with the result of alpine skiing 63.58+ moved to the penultimate ranking position after the course. This, in a way, paradox of results migration is not isolated and divides students into two groups in this respect. Four students improved their results, while seven worsened. The factor that differentiated the two groups was the fact that the training of the four was conducted by an instructor with 39 years of experience, while the other with only three years. This, however, is not a sufficient argument for unambiguous inference of the reasons.
Conclusions: The diagnostic exercise system used (non-apparatus version) turned out to be a sensitive and simple tool for measuring AOUMS changes under the influence of intense stimuli burdening the lower limbs with many hours and many days of physical effort.
