Tennis serve kinematics#
This dataset was kindly provided by Fraje Watson, Steve Taylor and Jin (Derrick) Gaokuang from the University College London, Aspire CREATe lab.
These are the bilateral kinematics of four tennis serves, sampled at 50 Hz. The laboratory vertical axis is z.

kinematics_tennis_serve.c3d: Labelled markers, no events, no forces, no analog signals
kinematics_tennis_serve_nan.c3d: Same askinematics_tennis_serve.c3d, with simulated missing samples on Derrick:RSHO.
filename = ktk.doc.download("kinematics_tennis_serve_nan.c3d")
markers = ktk.read_c3d(filename)["Points"]
markers.plot("Derrick:RSHO")
kinematics_tennis_serve_2players.c3d: Similar tokinematics_tennis_serve.c3d, but with a simulated second player named Viktor. In this case, the marker set is:
