Rowing

Overview

Rowing (on an ergometer / rowing machine) is a low-impact, closed-chain, full-body aerobic exercise that engages approximately 85% of the body's musculature in a single coordinated movement. It is one of the five core low-impact cardio modalities recommended for cardiac rehabilitation patients, particularly those in Phase III transitioning toward higher aerobic capacity.

Key Facts

  • Modality type: Aerobic + strength (concurrent)
  • Impact classification: Low-impact -- eliminates gravitational joint load on ankles, knees, hips, and spine
  • Muscle engagement: Quadriceps, hamstrings, gluteals (leg drive); latissimus dorsi, rhomboids, trapezius (pull); core (transfer); biceps, forearms (grip)
  • Position: Seated -- eliminates fall risk associated with weight-bearing exercises
  • Phase applicability: Phase II (low resistance, 5-10 min) through Phase IV (extended sessions at moderate intensity)

Technique Sequence

The rowing stroke follows a specific kinetic chain sequence: 1. Leg drive: Push through the legs while keeping arms straight and core engaged 2. Core transfer: Lean slightly back (no more than 11 o'clock position) as legs fully extend 3. Arm pull: Draw the handle toward the lower ribs with a straight back 4. Return: Reverse the sequence -- arms out first, then hips flex, then legs bend

Critical safety point: The back must remain flat throughout the stroke. Rounding the spine during the pull phase creates lumbar disc compression and shear risk, particularly for older adults with pre-existing degenerative disc changes.

Cardiac Application and Dosage

  • Phase II entry: Drag factor 3-4, 5-10 minutes, focus on technique rather than output
  • Phase II progression: Increase time by 1-2 min/session; hold intensity constant
  • Phase III: 15-25 minutes at moderate resistance; RPE target 11-13
  • Phase IV: 20-40 minutes at self-selected intensity; 3-4 sessions/week

Rowing provides an efficient cardiorespiratory challenge because the large muscle mass engaged produces high oxygen demand, raising stroke volume and cardiac output without imposing joint impact.

Beta-Blocker Interaction

Beta-blockers cause chronotropic blunting -- the heart rate response to exercise is attenuated. Target heart rate formulas (Karvonen) still work if HR_max is measured via GXT (not estimated from age-formula). RPE becomes the more reliable intensity guide than heart rate alone.
