Effects Of Wind Tunnel Simulation Oneffects Of Wind Tunnel Simulation On Muscle Function And Force Generation Characteristics In Nordic Combined

PURPOSE: Past studies assessed training effects and mechanism using strength or speed monitoring, energy metabolism monitoring. This article aims to enrich research on wind tunnel training by studying the effects of wind tunnel simulation training on muscle function and strength. METHODS: Six athletes from the China Nordic Combined national team (Age 20.6 ± 2.7, height 177.33 ± 3.19, weight 60.42 ± 3.31, training duration 4.33 ± 1.03), participated in a 16-week repeated-measures experimental design. In the initial 8 weeks, all the athletes underwent regular platform jumping training (Training period-1, TP-1). Subsequently, in the following 8 weeks(Training period-2, TP-2), all the athletes added 1 hour of wind tunnel simulation training on the basis of the original regular platform jumping training, and conducted 2 tests (pre-test Athletic ability testing-1, AT-1; post-test Athletic ability testing-2, AT-2) on the athletic qualities, postures, and mechanical parameters of the 6 athletes before and after the addition of the wind tunnel simulation training to evaluate the effect of wind tunnel training. RESULTS: After TP-2 training in 6 athletes the average time pushing off and the YBT-LQ lateral and medial difference between right and left leg extension,which was a significant difference (p < 0.05), and the total FMS score has a significant difference (p < 0.01).The average distance pushing off was significantly shortened (AT-1:4.13 ± 0.40;AT-2:3.09 ± 0.67;p < 0.01), the athletes' mean combined speed and mean angle of the horizontal plane were significantly reduced (AT-1:9.32 ± 0.87;AT-2:5.58 ± 1.30;p < 0.01), and the mean combined speed of the introduction was significantly increased (AT-1:19.95 ± 0.48;AT-2:24.29 ± 0.73:p < 0.01), the athletes' average jumping distance was increased by 3.80 m. CONCLUSIONS: Wind tunnel simulation training can optimize the energy distribution of muscles during exercise and improve the physiological adaptability of athletes' muscle tissues in high-speed exercise.
