Texas State University Kinesiology Worksheet
Description
1. Answer the questions based on the given GRF data. Note: the force was normalized to participants body weight. The body weight is 961.794 N. The sampling rate is 1200 Hz.
1a. The GRF data represent what type of movement? (2 pts)
1b. Calculate the support time (from touchdown to toe-off). (2 pts)
1c. Calculate the peak VGRF, peak braking force and propulsive force in newton. (4 pts)
1d. Present the VGRF in a graph using APA style. (4 pts)
1e. Calculate the peak loading rate in VGRF. (3 pts)
2. Answer the following questions based on the given COP data during quiet standing for a child with Autism Spectrum Disorder (ASD) and a typical developing (TD) child. Note: the sampling rate is 1200 Hz.
2a. List and explain two different postural stability variables of COP data that may be calculated and have been used in the literature. Citations should follow APA style. (7 pts)
2b. Calculate the anteroposterior displacement of COP (Ax) and include the correct unit. (3 pts). Hint: max(Ax) min(Ax)
2c. Calculate the mediolateral displacement of COP (Ay) and include the correct unit. (3 pts).
2d. Calculate the COP sway area based on answers in 2b and 2c. (1 pts)
2e. Compare the sway area between the ASD and TD participants and explain who has better stability. (1 pts)
