Reviews of elite karate athletes (Chaabene et al., 2012) conclude that explosive power is central to high-level performance — so the training emphasis belongs on rate of force development, not just a big one-rep max. But don’t swing too far: elite karateka do out-lift novices on measures like the squat, so a strength base matters — power is built on it, it doesn’t replace it. (The blog claim that “max strength doesn’t matter at all” is weaker than it sounds; treat it with caution.)
This is where the karate-specific evidence is strongest: studies suggest ~6 weeks of plyometric training improves lower- and upper-body power in karate athletes (e.g. Ioannides et al., 2020 — small, mostly young samples, so promising rather than definitive). A practical menu:
Keep volume low, take full recovery between reps, and prioritise quality over fatigue — plyometrics only build power when you’re fresh.
Frequency: about 2× a week of dedicated strength/power, so it supplements rather than crowds out mat time — on separate days from, or after, hard karate sessions. Periodise: build a strength base in the off-season, then shift emphasis to power and plyometrics in-season (the “conversion” from strength to explosive output), tapering near competition. Recover: power quality depends on being fresh, so don’t stack heavy lower-body lifting right before technical or sparring sessions.
Everything above feeds the things Shotokan cares about: kime (a braced, powerful terminal contraction — core bracing plus the eccentric control to decelerate), hip-rotation power for the gyaku-zuki (rotational med-ball and anti-rotation work target it directly), stance endurance for long kata (isometric and tempo work — paused squats, stance holds), and the one-strike power behind ikken hissatsu (why you train maximal explosive output rather than endurance reps for striking).
