Active vs. Passive Range: Closing the Gap with Bands

Students check the difference between how far a joint goes with help (passive range) and how far they can control it on their own (active range). Then they train with resistance bands to build strength at the end of the range and retest.

How to play

1. Demo the difference between passive and active range and explain why uncontrolled range is where most injuries happen (3 min).
2. In pairs: lying face up, measure the straight leg raise pulling with the band (passive) and then without help (active) with a phone inclinometer on the shin; write down the gap in degrees (6 min).
3. Leg work: with the band on the ankle as light resistance, 3 sets of 8 active raises holding 2 seconds at the top, plus 10-second pushes against the band at the end point (7 min).
4. Shoulder work: standing facing the wall, raise the arm as high as possible and lift the hand off the wall for 3 seconds; 3 sets of 6 per arm (5 min).
5. Repeat the active measurements and calculate how many degrees the gap has changed (4 min).

Rules

• The knee of the lifting leg stays straight and the opposite hip stays on the floor.
• For the passive range, pull the band gently, never to the point of pain.
• Bands are anchored securely to the foot or ankle and never released while under tension.
• The partner watches for cheating, such as lifting the pelvis or arching the back.

Variations

Adaptations

• Limited mobility: does the active-passive comparison at the shoulder and elbow from the wheelchair.
• Hypermobility: focuses on active work and skips forced passive measurement.
• Visual impairment: the partner calls out the degrees and touches the area that must stay still.

Learning goals

• Tell the difference between active and passive range of motion.
• Build strength and control at the end of a joint's range.
• Measure range changes with objective data.

Teacher tip

Students are often surprised that the gap is 20–30 degrees; use it to explain why stretching without strengthening carries over poorly to sport.
