Ground Contact Time

Duration of foot contact during gait; lower and symmetrical = more efficient CPG.

Ground Contact Time (GCT) is the duration each foot spends in contact with the ground during walking or running. Shorter, symmetrical GCT typically indicates efficient CPG-driven gait and better running economy.

Key Points

  • Asymmetry — uneven GCT suggests CPG imbalance or compensation
  • Cadence — higher cadence usually shortens GCT
  • Surfaces — uneven terrain and minimalist footwear can recalibrate CPG and GCT
