Four blocks instead of nonstop training: when strength, plyometrics and sprints work, when prevention starts and why the season is maintenance, not building.
When in the year do I actually train what? The short answer: build strength and jump power in summer, turn it into ice speed in late summer, arm the prevention programme in preseason, and maintain during the season — nothing more. The order is not a matter of taste but follows the numbers from training research.
The key evidence is an eight-week block: when plyometrics were placed first in three of five weekly strength sessions, the 10-metre sprint on ice shortened by 2.8 percent compared with strength training alone [1]. Over ten metres that is the half stride that decides who gets the puck. And resisted sprints on ice shifted the force profile clearly in a randomised study: plus 22 percent horizontal maximal force, plus 24 percent horizontal maximal power and plus 7 percent in the ratio of force — the share of force that actually goes forward instead of down [2].
The second reason for a yearly plan is less pleasant. Around 74 percent of all injuries happen in games, while practice incidence sits very low at 0.4 to 2.6 per 1000 hours [6]. Meaning: the season is the risky phase, not the summer. So the build belongs in the time without games — and the prevention right before them.
Recovery, build, conversion, maintenance. After the last game come two to three quiet weeks without structure — your body has a season behind it. Then follows the long strength block, then the explosive conversion block, and with the first league game you switch to maintenance. Treat all four phases the same and you train mediocre all year.
Squats, deadlifts, single-leg variations, heavy pulls — two to three sessions a week over several weeks. The reasoning sits in the correlations: on-ice sprint performance is linked to isometric strength and even more strongly to the jump test [4]. Summer is the only phase where you are truly allowed to get heavier — later you lack the recovery for it.
Now strength becomes speed. Put jumps at the start of part of your strength sessions, while you are fresh — exactly that pattern produced the 2.8 percent faster 10-metre time on ice over eight weeks [1]. Add horizontal resisted sprints, because they shift the force profile measurably forwards [2]. Eight weeks is short enough to see through and long enough to work.
Six weeks before it gets serious comes the best-documented block of all. A six-week functional adductor strengthening programme cut groin strains in professional hockey to 0.71 instead of 3.2 per 1000 game exposures, and in the at-risk players incidence fell from 38 to 9 percent [3]. Why it works so well sits in a second study: players whose adduction strength was below 80 percent of their abduction strength were affected around 17 times more often [8]. The strength ratio beats stretching.
From the first league game: volume down, intensity held. One to two short, heavy strength sessions a week, one short jump stimulus, the adductor programme at reduced dose. Plus one or two easy endurance sessions — a higher maximal oxygen uptake (around 55 to 65 ml/kg/min in elite players, the condition of a committed endurance athlete) goes with better maintained repeated sprint performance and faster heart rate recovery [5]. During the season you gain nothing — you defend what the summer built.
This is where most recreational players make their mistake of the year. After a game, muscle glycogen is reduced by around 31 percent and only back to baseline on day 2, voluntary maximal strength sits at minus 11 percent, and electrically measured low-frequency force drops by 29 percent — while repeated sprint performance is back after a single day [7]. So your sprint feel recovers faster than your fuel tank. Therefore: heavy strength no earlier than two days after a game, technique and sprint work may come sooner.
Plyometrics, resisted sprints and heavy compound lifts are stimuli with high peak loads. They belong exclusively in a rested state, after a full warm-up — and not the day before a game. Increase sprint and jump volume by no more than about a fifth per week and plan at least one completely training-free day.
The adductor programme is prevention, not competition: slow, controlled, pain-free. A pull in the groin means a break and a conversation, not more repetitions — and persistent groin pain belongs in sports medical assessment [8].
With pre-existing conditions, a long break or from around 35 onwards, a sports medical check belongs before any maximal strength or interval block. This guide explains structure and evidence and does not replace individual training or health advice.
Put two fixed test days in your year: one at the start of the summer and one ten days before the first league game. Both times you measure the same two things — a jump test and the 10-metre time on ice. That exact combination reflects the documented link between off-ice strength and on-ice speed [4], and it is where the eight-week block showed its 2.8 percent [1].
The trick lies in the interpretation. If your jump rises but your ice time does not, it is technique — then the next block belongs on the ice, not in the gym. Without those two data points you plan every year by feel, and feel is always optimistic in summer.
Four blocks: two to three weeks of recovery after the season, then a long strength block focused on maximal strength and jump power [4], then a roughly eight-week conversion block with plyometrics first and resisted sprints [1][2], and from the first league game maintenance at halved volume. Running alongside from six weeks before the season is the adductor programme [3].
The documented conversion block lasted eight weeks with five strength sessions a week, three of them starting with jumps — producing a 10-metre on-ice sprint 2.8 percent faster [1]. For recreational players with fewer sessions the same principle applies at a smaller dose: eight consistent weeks with three sessions beat twelve half-hearted ones.
One to two short, heavy sessions a week plus a short jump stimulus. In season you hold intensity and cut volume, because the games themselves are already the highest load — around 74 percent of all injuries happen there [6]. On top, one or two easy endurance sessions are enough for recovery between shifts [5].
In the six weeks before the season starts, continuing afterwards at a reduced dose. A six-week functional adductor programme cut strains to 0.71 instead of 3.2 per 1000 game exposures, and in the at-risk group from 38 to 9 percent incidence [3]. If you want to know whether you are in that group: an adduction-to-abduction strength ratio below 0.8 came with around 17 times higher risk [8].
Technique and short sprints can return early — repeated sprint performance is recovered after one day. Heavy strength waits, because muscle glycogen is only back on day 2, voluntary maximal strength sits at minus 11 percent and low-frequency measured force drops by 29 percent [7]. Translated: your legs feel good earlier than your tank is full.
