The Texas Tech University Youth Physical Development Study

Faculty members in the Department of Health, Exercise, and Sport Sciences are in need of healthy elementary, middle, and high school children (ages 5-18) for a study. Muscle strength and mass, body composition, and jumping power will be assessed on two separate occasions. All testing will take place in the Human Performance and Muscular Assessment Laboratories within the Department of Health, Exercise, and Sport Sciences. For more information, please contact Dr. Matt Stock.

 

Time course for strength and agonist-antagonist coactivation following acute eccentric exercise 

muscles

Healthy women between the ages of 18 and 35 that have not been involved in a structured upper-body strength training program during the previous six months are invited to participate in a study. The study requires five visits to the Muscular Assessment Laboratory (room 107). The first, third, and fifth visits will take roughly 30 minutes. The second and fourth visits will each take slightly more than two hours.  For all five visits to the laboratory, we will test the strength of your arm muscles using dumbbells and/or a device called an isokinetic dynamometer. For either the second or the fourth visit, you will be asked to perform a workout that involves lowering a heavy dumbbell for six sets of ten repetitions.  We expect that this workout will make your arm muscles very sore. This investigation will also utilize a technique known as electromyography, or EMG, to measure muscle activation. If you are interested in learning more about this study, please contact Kendra Olinghouse.

Research Environment

Faculty members within the Department of Health, Exercise, and Sport Sciences have research agendas that answer important questions related to adaptations to strength training, the non-invasive assessment of muscle function, the rate of force/torque development, and many other topics.  As shown below, the Human Performance and Muscular Assessment Laboratories are well-equipped with the latest and most sophisticated research technology, allowing our department to perform a variety of very unique experiments.  We believe strongly in student mentorship.  Graduate and undergraduate students have the opportunity to make important contributions to our research studies.

Muscular Assessment Laboratory (Room 107)

Muscular Assessment Lab

biodex

The Muscular Assessment Laboratory was designed to allow researchers to study muscle strength and function of the lower body during isokinetic, isometric, and dynamic constant external resistance (DCER) muscle actions.  A mobile computer cart with Delsys electromyographic (EMG) equipment is often wheeled in and out of the lab as well.  The equipment in the Muscular Assessment Laboratory includes a Biodex isokinetic dynamometer, a custom-built chair designed to measure isometric strength of the leg extensors, and DCER leg extension and curl machines.

Human Performance Laboratory (Room 103)

Human Performance Laboratory Racks

The Human Performance Laboratory is conveniently located in the middle of our brand new building.  This large facility (82 ft x 32 ft) allows researchers to perform data collection for multiple studies simultaneously.  The Human Performance Laboratory also has office space for our young, ambitious graduate students that are working on data collection, entry, and analysis for their thesis projects.  The Human Performance Laboratory’s current research equipment and testing capabilities include:
