Kinesiology
The Department of Kinesiology seeks to provide an ample knowledge of physical activity and active living to students both within and outside of the program; by providing knowledge of the role of movement and physical activity throughout the lifespan, it seeks to improve the lives of all members of the community. Its options for students enrolled in the department include: Athletic Training; Community and Public Health; Exercise Sciences; Pre-Health Professions; and Physical Education Teacher Licensure. The Department of Physical Education was founded in 1974 from the merger of the Department of Physical Education for Men and the Department of Physical Education for Women. In 1981 its name changed to the Department of Physical Education and Leisure Studies. In 1993 its name changed to the Department of Health and Human Performance. In 2007 its name changed to the Department of Kinesiology. Dates of Existence: 1974-present. Historical Names: Department of Physical Education (1974-1981), Department of Physical Education and Leisure Studies (1981-1993), Department of Health and Human Performance (1993-2007).

Abstract

In many modern sports where an explosion of power/strength is necessary, such as weight lifting, shot put, and tennis, athletes often yell or grunt to "psych-up" and improve performance. Martial artists have been using a similar technique for centuries called a "kiap". Unfortunately, there is little scientific evidence that yelling or kiaping improves performance. Therefore, this study examined the effect of kiaping on strength during a handgrip exercise in novices and experts. Fifty participants (25 novice and 25 expert martial artists) completed a handgrip strength test under three conditions, a baseline test, a no kiap control condition, and a kiap condition. Strength increased by a mean of 8% (p < 0.001) for the combined expertise levels in the kiap condition compared to the baseline and no kiap conditions. There was also a significant interaction (p < 0.05) between expertise level and condition, with a medium effect size of 0.48 for novices and a small effect size of 0.25 for experts. The results of this study indicate that the kiap may increase hand grip strength in participants with as little as two months of training, benefiting novices slightly more than experts, and additional training may not result in further increases in strength.
