Speed is equal to the cycle length (CL) times the cycle rate (CR). Cycle rate (CR) is the inverse of cycle time (CT). One cycle is defined as the period from when a foot impacts the ground until the next time that same foot impacts the ground again. In collecting kinematic data on running, it makes sense to gather data for two cycles at a time, to ensure you are getting an average of what is happening on both legs, and not just one side. You are analyzing the running kinematics for a subject at the beginning of a sprint. You time and measure their displacement for their first 10 cycles. You analyze those 10 cycles in 5 2-cycle segments (Segments 1-5, in that order). The data is as follows: Segment 1: 5.5 meters in 1.05 seconds Segment 2: 6.5 meters in 0.92 seconds Segment 3: 7.1 meters in 0.88 seconds Segment 4: 7.1 meters in 0.81 seconds Segment 5: 7.0 meters in 0.77 seconds
