Jump analytics
Record two jump types in one set and Metric Jump compares them: eccentric utilisation, L / R balance, arm swing and bilateral index.
Record a CMJ and a paused squat jump in the same set, and Metric Jump shows how much height your countermovement adds. Pair other jump types in one set to get the other comparisons. Each one appears on the Symmetry & ratios card on the set summary. Tap the i on the card to read a short explanation under each bar.
Record the right jumps
Metric Jump classifies every rep as you go, so you do not tag anything. Record both jump types in the one set. See Jump classification.
| Comparison | Record in the same set |
|---|---|
| Eccentric utilisation | A CMJ and a paused squat jump |
| L / R balance | A single-leg jump on the left and one on the right |
| Arm swing contribution | An Abalakov and a hands-on-hips CMJ |
| Bilateral index | A left single-leg jump, a right single-leg jump and a CMJ |
| L / R balance (repeat jumps) | A left and a right repeat jump test in the same recording |
Every comparison uses the highest rep of each jump type in the set. One poor rep does not drag a score down. A hidden rep does not count.
Eccentric utilisation
Eccentric utilisation is your best CMJ height divided by your best squat jump height.
At 1.0 the two jumps reach the same height, so the dip and rebound of the countermovement add nothing. Above 1.0, the card reads Elastic-dominant. Below 1.0, it reads Force-dominant: your paused squat jump went higher than your CMJ.
L / R balance
Metric Jump takes your best left and best right single-leg heights. It reports the gap between them as a percentage of the higher side, with L stronger or R stronger beside it. A gap under 1% reads Even.
Metric Jump uses 10% as its guide. Up to 10%, the insight reads Well balanced. Above 10%, it reads Notable asymmetry. The 10% line is Metric’s guide, not a published norm.
Arm swing contribution
The contribution is the height your Abalakov adds over your hands-on-hips CMJ, as a percentage of the CMJ:
(Abalakov − CMJ) ÷ CMJ × 100
A positive number means the arm swing added height. A negative number means your Abalakov jumped lower than your CMJ.
Bilateral index
The bilateral index sets your best CMJ height against your best left and best right single-leg heights added together. The card shows the size of the gap and which side is higher.
- L+R higher — your two single-leg jumps add up to more than your CMJ. The insight reads Strong single-leg output. Sports science calls this pattern a bilateral deficit.
- CMJ higher — your CMJ beats your two single-leg jumps added together. The insight reads Bilateral facilitation.
Neither direction is a fault on its own. Use the first result as the baseline, and retest against it.
L / R balance on repeat jumps
A repeat jump recording with a left test and a right test gets the same L / R balance bar, built on RSI instead of height. Metric Jump takes the best left RSI and the best right RSI, and reports the gap as a percentage of the higher side. The labels under the bar read Pogo · L and Pogo · R, each with its RSI.
If you run more than one test on a side, Metric Jump uses the best one. A hidden test does not count. See Repeat jumps & hops.
When a score is missing from the card
- A jump type is missing. Metric Jump still reports every rep, but it leaves that comparison off the card.
- A squat jump has a small bounce. Metric Jump labels it a CMJ and leaves eccentric utilisation off the card. Record another squat jump with a full 1-second pause.
- The trend line has gaps. A composite score plots only on days when a set held the right jump mix.
