Relationship between strength qualities and short track speed skating performance in young athletes

Abstract

This study analyzed the relationships between isometric as well as concentric maximum voluntary contraction (MVC) strength of the leg muscles and the times as well as speeds over different distances in 17 young short track speed skaters. Isometric as well as concentric single-joint MVC strength and multi-joint MVC strength in a stable (without skates) and unstable (with skates) condition were tested. Furthermore, time during maximum skating performances on ice was measured. Results indicate that maximum torques during eversion and dorsal flexion have a significant influence on skating speed. Concentric MVC strength of the knee extensors was higher correlated with times as well as speeds over the different distances than isometric MVC strength. Multi-joint MVC testing revealed that the force loss between measurements without and with skates amounts to 25%, while biceps femoris and soleus showed decreased muscle activity and peroneus longus, tibialis anterior, as well as rectus femoris exhibited increased muscle activity. The results of this study depict evidence that the skating times and speeds are primarily influenced by concentric MVC strength of the leg extensors. To be able to transfer the strength onto ice in an optimal way, it is necessary to stabilize the knee and ankle joints.

Block periodization of strength and endurance training is superior to traditional periodization in ice hockey players

“…These capacities have previously been associated with better skating sprint performance. 6 Despite favorable adaptations in the BP group in the ability to produce rapid force, there was no significant difference between BP and TRAD in changes in vertical jump ability. This was somewhat surprising, as vertical jump performance seems to be an accurate manner of predicting the ability to produce power in the lower limb extensor muscles.…”

“…Skating acceleration and maximal skating velocity are among the most important physical determinants of ice hockey performance. [1][2][3] Previous studies have observed associations between skating sprint performance and off-ice performance characteristics, such as vertical jump performance 4,5 and muscular strength, 6 though for the latter, other studies have provided conflicting results. 5,7 Furthermore, maximal oxygen uptake (VO 2max ) is important for ice hockey players' ability to perform repeated sprints.…”

Physiological and technical commitment during a 300-m in-line skating trial in athletes of different age categories

“…5,6 Skaters with higher strength and explosive power of the lower limbs perform better in terms of skating time and speed. 2,7 The prolonged muscle contraction imposed by the squatted posture induces also a blood flow restriction in the muscles, 8 as supported also by near infrared spectroscopy studies. 9 Consequently, blood lactate concentration ([La -]) is higher in skating than in running at similar exercise intensity.…”

“…Skating performance is influenced by many factors comprising strength, technique, pacing and level of experience. [1][2][3][4] High levels of maximum strength of the lower limbs are necessary in this discipline as skaters assume a markedly squatted position to reduce of air friction, with small angles at both the hip and knee joints. 5,6 Skaters with higher strength and explosive power of the lower limbs perform better in terms of skating time and speed.…”
