Cadence • Report ZS-104
A 12-week telemetry evaluation of 84 sub-3:30 marathon runners demonstrating a 14% reduction in peak horizontal braking force when increasing cadence from 166 to 174 spm.
Kinetics • Report ZS-109
Quantifying vertical leg-spring stiffness and elastic energy return during threshold intervals on tartan track surfaces versus asphalt road courses.
Pacing • Report ZS-112
Analyzing how hip extension angle degrades by up to 4.2 degrees in the final 10K of a marathon and which isometric heavy-resistance routines preserve terminal stride length.
Kinetics • Report ZS-115
Mechanical compression bench tests comparing virgin PEBA midsoles against pairs logged for 350 kilometers of winter road running in Nordic temperatures.
Cadence • Report ZS-118
Why maintaining constant ground contact time on rolling hills outperforms fixed stride-length running for preserving quadriceps eccentric integrity.
Pacing • Report ZS-121
Comparing foot-pod power meters (Watts) against optical heart-rate zones when pacing coastal half-marathon courses with headwinds exceeding 6 m/s.
