The influence of altitude training on the manifestation of muscle force in the lower limbs and aerobic endurance on students specializing in ski

Abstract

Abstract Aim and purpose : It has been widely accepted in the athletic community that altitude training can increase performance at sea level, therefore this study aims to analyze the influence of altitude training on the manifestation of muscle strength in the lower limbs and aerobic endurance in students participating at in-depth training course in a branch of sports- skiing, on the “living high-training high” model. Material : This study included 9 students from the Physical Education and Sports Faculty of Timisoara, who took the in-depth training course in a branch of sports- skiing, taking part in the program and activities specific to this course, as well as in the training carried out at altitude. Method : The batch was evaluated in two moments (T0 and T1), using the following assessment tests: Yo -Yo, Roman seat in isometry, high jump evaluated via the OPTOJUMP device, long jump test. The data was processed in Excel (v2205) and the statistical processing was performed using the Student T-test. It was considered that the results are statistically significant for values of p <0.05. Results : The progress recorded was quantified by normalizing the absolute values and was expresse d as a percentage as follows: Yo-Yo= -1% ± 0.08 STD; RS= + 168% ± 1.26STD; HJ-Squat Jump= -4% ± 0.16STD; HJ- countermovement jump= -2% ± 0.14STD; HJ- countermovement jump-free arms = + 2% ± 0.14STD; LJ= + 6% ± 0.04STD; LJ SLJ R= + 9% ± 0.08STD; LJ SLJ L= + 10% ± 0.08STD. Conclusions : From the evaluations performed at sea level, at T0 and T1, a noticeable improvement in the muscular strength of the lower limbs has resulted via the following tests: the Roman seat in isometry, long jump with bilateral support, long jump with unilateral support on either the left or right side; registering a significant statistical (p). However, there was no significant improvement noticed on the rest of the tests.
