The Comparison of Isokinetic Performance Profile of Knee and Ankle Joint Muscles in Professional and Amateur Speed Skaters
This study proposed to compare the isokinetic performance profile of knee and ankle joint muscles in professional and amateur speed skaters. Sixteen speed skaters divided into two groups of amateurs and professionals were included in this survey. Isokinetic parameters of ankle and knee joints evaluated by using the Biodex isokinetic-dynamometer. Shapiro-Wilk and independent t-test were applied for statistical analysis at the significant level of ≤0.05. Independent sample t-test results showed a significant difference in isokinetic parameters such as the power of knee extensor muscle, power and deceleration time in inversion and eversion between amateur and professionals. It seems that the significant difference between professional and amateur speed skaters in isokinetic parameters is related to neuromuscular ability (power and deceleration time of invertor and evertor muscles groups). It is suggested that these parameters be considered in the training of this group of athletes.
