Jay’s In-Season Performance Testing
Why:
In-season, the goal isn’t to guess how an athlete is coping. This battery gives us a full picture of strength, power, elasticity, and injury risk in one session.
How this helps us program: Every test directly shapes Jay’s next training block, what gets loaded, what gets managed, and what gets protected before it becomes a problem.
IMTP:
Why we do this test: Isometric Mid-Thigh Pull.
This tests maximum force and rate of force development (how fast he reaches that force, not just how much).
What it tells us: If peak force is fine but early RFD (0–200ms) is down, this we’ll help determine whether we load heavy or train explosive intent.
Run Specific Iso (Ankle):
Why we do this test: Single-leg isometric strength test, specific to the ankle complex, gastrocnemius-dominant.
What it tells us: How much force each ankle can produce independently. This is critical for sprinting, change of direction, and identifying left-right imbalances and flag if needed.
Hop Test (10 hops, best 5 averaged):
Why we do this test: Reactive strength and Fatigue.
Jay completes 10 continuous hops, and we average his best 5 to get a true reactive strength number, while still using the full set of 10 to see if RSI decays under repeated efforts.
What it tells us: The best-5 average tells us his true reactive strength ceiling. The decay across all 10 tells us his stiffness/fatigue resistance.
If RSI drops off late in the set, we’ll know that his reactive capacity needs work, not just more jump volume.
CMJ:
Why we do this test: Measures force, power, and how efficiently strength converts into vertical power output, we also view left-right asymmetry on landing.
What it tells us: This tells us a lot more than how high someone can jump. A few examples are;
- If jump height is down but force output is the same, this could be due to a technique/timing issue, not a strength issue.
- If jump height is up but eccentric peak velocity is down, he’s biasing muscular contraction over the stretch-shortening cycle to get there, same result, different strategy, and it changes what we program.
Drop Jump:
Why we do this test: Peak reactive strength under a st
