The effect of alcohol drinking on the isokinetic knee strength
Vopat, Jan ; Strejcová, Barbora (advisor) ; Dvořák, Martin (referee)
Title: The effect of alcohol drinking on the isokinetic knee strength Objectives: The objective of this thesis is to assess the effect of alcohol on isokinetic knee strength during extension and flexion. Methods: Fifteen volunteers participated in this study. Their age was 23,9 ± 1,9 years, height 179,5 ± 7,2cm and weight 78,5 ± 7,95kg. They were all students from sports faculty. One group of volunteers was given alcohol with juice (0,8g of alcohol to 1kg of fat-free mass), the second group drank only juice. We used the switch design study. We measured isokinetic knee strenght on dynamometer Cybex Humac Norm (Cybex NORM ®, Humac, CA, USA) in three types of angular velocity (6Oř/s, 180ř/s, 240ř/s). The parametrs were peak torque, muscular work, average muscular power and time to peak. Results: We registered statistically significant increase of peak torque, muscular work and average muscular powers when measuring flexion in all the three angular velocities (60ř/s, 180ř/s, 240ř/s). We did not register statistically or effect size significant diference readings of time needed for maximal peak torque when measuring flexion and extension. The only exception was angular speed 240ř/s where we registered a factually significant change in time needed for extensors to reach the maximal peak torque....
