Key Takeaways Explain This Topic AI

DCO 3.B.7 covers walking, running, swimming, and aerobic dance/group cardio—the same instruction standard as machines, without a console.

Foot-strike pattern (rearfoot, midfoot, or forefoot) is individual; do not treat one strike as dogma.

Walking typically contacts somewhat in front of the body; running should land more under the hips, with a flight phase.

Swimming and water walking are non-weight-bearing or buoyant options when impact or axial load must drop.

Progress walk → jog → run; outdoor sessions need heat, cold, hydration, and surface plans, and group classes need tempo and impact modifications.

Coaching cardio when there is no console

DCO 3.B.7 tests instruction in non-machine cardiovascular activities : walking, running, swimming, and aerobic dancing (including many group-fitness patterns). Intensity still comes from speed, grade (hills), interval structure, water tempo, or music beats per minute (BPM) —you just cannot hide behind a "quick 8" button. Video items may show overstriding, a class that never offers a low-impact option, or a client sent out for a noon run in extreme heat with no water plan.

Gait: walking vs running

Walking keeps at least one foot on the ground (double-support phase). Typical walking roll is heel-to-toe, with contact somewhat in front of the body. Cue an upright ribcage over the pelvis, eyes on the horizon, and an arm swing that opposes the legs. A shuffling, toe-out, or Trendelenburg pattern belongs in your assessment notes (Domain 1) and may change modality before you "just add miles."

Running adds a flight phase . The biomechanical change you should be able to name on the exam is that foot contact shifts toward landing more under the hips rather than reaching out in front of the body. Overstriding (a long, braking heel poke) raises impact peaks and is a common injury-adjacent error. A slight increase in step rate (cadence) often shortens that reach without requiring a new "identity" as a forefoot runner. Ranges near 170–180 steps per minute appear in coaching literature as a starting experiment , not a law every client must hit.

Foot strike is individual, not dogma

Clients land rearfoot, midfoot, or forefoot . Successful endurance athletes exist in all three. Forcing a midfoot or forefoot strike on a lifelong rearfoot walker often creates calf–Achilles overload. Forcing a heavy heel strike on a natural midfoot runner is equally unhelpful. Coach what you can see:

• Contact under the body rather than a long brake in front
• Quiet, stacked posture rather than a sit-back "running in the chair"
• Cadence high enough to avoid overstride, without frantic chopping
• Shoes that match the surface and the client's current pattern—not a fashion last

If pain appears when you change strike, revert and refer when pain is sharp, night-waking, or swollen. Technique is not a substitute for medical care.
