Fig. 4From: Effect of speed and gradient on plantar force when running on an AlterG® treadmillAverage contact times [ms] mean ± SD (error bars) vary with gradient for speeds 12 & 15 km/hr. averaged. 15 km/hr. was the top speed when running the treadmill belt in reverse to get the decline trials. Therefore, the common speeds use for both incline and decline conditions have been averaged for comparisonBack to article page
