The role of SSC cycle in ice hockey off-ice training

Abstract

The Stretch and shortening cycle (SSC) is one of the most common used mechanism
in a human body. The objective of this study was to determine a level of slow and fast stretchshortening
cycle utilization in elite ice hockey players and prescribe some off-ice training
recommendations. The sample included 23 professional ice-hockey players of the Slovak
Tipos league team HKM Zvolen (2 goalkeepers, 7 defenders, 14 forwards; age 26 ± 4.79
years; height 182.87 ± 6.28 cm; bodyweight 87.22 ± 6.54 kg) in this research. The Depth
jump (DJ) test, the Bilateral squat jump test and the Bilateral counter-movement jump test
were recorded in order to analyze the players’ ability to use fast and slow SSC cycle in lower
limbs. The results showed no correlation between DJ and SJ or CMJ tests. However, Pearson
correlation revealed strong correlation between SJ and CMJ (p < 0.01, r2 = 0.949). 1 player
achieved better score in CMJ test within the range between 10 – 15 % (11.97 %). 16 players
scored better in CMJ test than SJ, but the percentage difference was insufficient (from 1.46
to 8.20 %) and finally higher SJ performance than CMJ performance was measured in 6
players (from 0.47 to 16.3 %). 6 players, who don’t utilize SSC efficiently due to their poor
tendon stiffness compared to high explosive muscle strength production were instructed to
add more plyometric exercises to their training regimen. On the other hand, 16 players were
more prone to injury due to insufficient load bearing capacity compared to their ability to
generate power. They were instructed to add more maximal strength exercises and strength
exercises with emphasis on eccentric phase of movement in order to build the capacity for
decelerative movements.
