The Side Hop Test measures repeated single-leg lateral hopping ability. It is useful for assessing lateral power, agility, endurance and asymmetry.
A client may be able to perform one lateral hop well, but repeated side-to-side hopping reveals how they manage rhythm, fatigue and control. The Side Hop Test is a simple way to assess this capacity.
Test name: Side Hop Test
Purpose: Assess repeated lateral hop ability
What it assesses: Lateral power, rhythm, endurance and control
Equipment: MAT or marked lines
Key finding: Successful hops in a set time
Best used with: Lateral Hop, Medial Hop, Square Hop and ankle/knee testing
Key limitation: A rep count alone does not capture quality
The Side Hop Test involves repeated single-leg hopping side-to-side over a line or marker. The MAT article describes hopping on the same leg from side to side, clearing the green markers on the MAT, often for 30 seconds, then recording successful hops with the Measurz rep counter.
It assesses repeated lateral lower-limb function, which may be relevant for sport, ankle rehabilitation and return-to-cutting progressions.
It measures successful lateral hops, speed, endurance, rhythm and control.
It does not diagnose injury or isolate strength.
Athletes, ankle rehabilitation clients, ACL rehabilitation clients, court and field sport clients, and people returning to lateral movement.

Set up the MAT or two clear side-hop markers.
The client stands on one leg outside the marker.
On “go”, they hop side-to-side over the markers on the same leg.
Each successful full clearance counts.
Continue for the chosen duration, commonly 30 seconds.
Repeat on the opposite side.
Record successful hops, errors and symptoms.
The score is the number of successful hops in the test period. Higher scores may suggest better lateral hop capacity, but errors, pain and poor control must be recorded.
The MAT article lists example values from studies of healthy adults but notes values vary by population and protocol. Use matched norms cautiously.
The MAT article cites Grindstaff et al. for lateral hop normative data and related balance/agility literature. Standardisation is essential.
Common errors include not clearing markers, touching the opposite foot down, inconsistent timing, poor counting and allowing uncontrolled landings.
Use the Side Hop Test to monitor lateral hop endurance, compare sides and assess ankle/knee control during repeated frontal-plane tasks.
Record side, duration, successful reps, errors, pain, fatigue, balance loss, confidence and movement-quality notes.
Repeated lateral hopping capacity on one leg.
The MAT article describes a 30-second option.
No. Record successful hops and error count separately.
The Side Hop Test measures repeated lateral hop performance.
Use a consistent duration and marker setup.
Record reps, errors and symptoms.
Compare sides cautiously.
