Almost 10 years before Paul Fitts published his landmark work formalizing the speed–accuracy trade-off for aiming movements, he was developing the genesis of this model with work targeted at the commendable goal of stopping airplanes from falling from the sky (Fitts & Jones, 1947; Fitts, Jones, & Milton, 1950). We begin with an overview of applied motor behavior research, with an emphasis on human performance psychology, and examine how that research gave rise to the modern discipline of ...

Are you experienced in using tai chi or qigong with older adults? In the Nov/Dec 2009 issue of Active Aging Today, we are pleased to showcase Paul Lam, MD, a world-renowned leader in tai chi for health. I invite anyone with knowledge and experience using tai chi, qigong, or other similar forms of exercise to share your program with the readers of Active Aging Today.
In addition, Lam has written four books: Overcoming Arthritis, Tai Chi for Diabetes, Tai Chi for Beginners and the 24 Forms, and Teaching Tai Chi Effectively. I very much enjoy creating the Tai Chi for Health programs, training people to teach the programs, doing research for those programs, and writing books to help people learn the programs. In fact, for anybody who wants to learn tai chi for health, the program we eventually produced is much more effective at improving people’s health and...
Typically, a serve and volleyer moves forward 20 to 40 percent more than a counterpuncher or an aggressive baseliner and about 20 percent more than an all-court player. The all-court player looks to be aggressive when hitting groundstrokes but is also happy to follow aggressive shots to the net to finish points. The all-court player should regularly practice approach shots, such as a big forehand or slice backhand hit from half court, and follow each shot to the net.

During the backhand volley, the upper arm decelerates through the eccentric...
