HUFC academy testing report
Overview
This report provides a brief overview force testing performance across the squad.
Counter movement jump
This test provides an estimate of a players ability to apply lower limb impulse. Counter-movement jump height has been presented as a measure of maximal lower limb impulse whilst RSI modified also considers the time taken to jump by adjusting counter-movement jump height for differnt contraction times. A high RSI represents a jump that is both fast and high.
The average jump height for “elite” male soccer players appears to between 37.5 to 40 cm1.
10-5 repeated jump test
This test provides an estimate of a players’ reactive strength, the reactive strength index (RSI) is a way of representing repeated jump height of the best 5 jumps whilst controlling for differences in contact time and presented in meters per second. As a general rule RSI values of ~2 m/s would be deemed good1, although work is needed to provide more robust normative data.
Profiling players based upon their repeated jump and counter-movement jump performance may be useful for programming (see scatter plot - dark red line represent group means).
| Contact time (ms) | Repeated jump height (cm) | RSI (m/s) | RSI (flight time) |
|---|---|---|---|
| 167.9 ± 27 | 32.6 ± 4.91 | 2 ± 0.38 | 3.1 ± 0.44 |
`geom_smooth()` using formula = 'y ~ x'
Hamstring strength
This test provides an overview of hamstring strength which could be important for sprinting movements. Poor hamstring strength is one risk factor for hamstring injuries. It is recommended that elite players apply a minimum of 350 N each leg. It is normal to have a dominant limb so some asymmetry is to be expected but larger differences between limbs maybe be worthy of further investigation.
| Test | Left | Right | Max |
|---|---|---|---|
| ISO 30 | 353.7 ± 68.2 | 362.6 ± 79 | 358.1 ± 72.1 |
| Nordic | 330.1 ± 47.3 | 339.1 ± 58.2 | 334.6 ± 48.6 |
Hip strength
This test provides an overview of groin (squeeze) strength and hip abductor strength. Poor groin strength is one risk factor for groin injuries. Vald perforimance have reported professional players apply a median of 380 - 470 N each leg. Groin strength and and hip abductor strength should be approximately equal??
It is normal to have a dominant limb so some asymmetry is to be expected but larger differences between limbs maybe be worthy of further investigation.
Hip abduction force refers to the maximal amount of force the player uses pushing out against the force frame.
| direction | Left | Right | Max |
|---|---|---|---|
| Pull | 393.2 ± 65.02 | 398.5 ± 76.71 | 395.9 ± 69.02 |
| Squeeze | 430.1 ± 61.05 | 436 ± 72.88 | 433 ± 65.32 |
Groin squeeze force refers to the maximal amount of force the player uses pushing in (squeezing) against the force frame.
Isometric mid-thigh pull
This test provides an overview of maximal force producing capabilities and total force (impulse) at specific time points. Note, impulse at <200 ms has shown questionable reliability with peak force the most trustworthy measure. Performance on the IMTP has been shown to correlate with sprint and change of direction speed test. Professional u23 male players have been observed to produce 2522 ± 242 N peak force, 1267 ± 199 N @ 100 ms, 1987 ± 201 N @ 200 ms.2
| Peak force (N) | Peak force (N /kg) | Force @ 100 ms (N) | Force @ 200 ms (N) |
|---|---|---|---|
| 2293.1 ± 462.3 | 34 ± 6.2 | 958.2 ± 273.5 | 1365.9 ± 379.9 |
