Motor Performance Study

The MPS was started in December 1967 by Dr. Vern Seefeldt (now Professor Emeritus) to examine the longitudinal relationships among physical growth, biological maturity and motor skill acquisition in children and youths. The study contained two major components, a research component and a program component. The research component involves semi-annual collection of data on 13 growth measures and 7 motor tasks.

From 25-30 participants are still active in this component. The program component provided instruction in various motor skills to children and youths from the ages of 2.5 to 13.0 years of age. The program was conducted on Saturday mornings during the school year and on a daily basis during selected weeks in the summer. Majors in kinesiology were required to participate in the activity program as cadet instructors. The program portion of the MPS was discontinued following spring semester 1999. A more complete history of the MPS is available in Chapter 4 of 100 Years of Kinesiology.
