Sex comparisons for neuromuscular function of the hamstrings and quadriceps following a barbell deadlift training program

Healthy men and women between the ages of 18-30 years are invited to participate in a research study to examine the effects of a barbell deadlift training program on hamstring and quadriceps strength, neuromuscular function, and vertical jump height.  If you have not engaged in a lower-body strength training program over the previous six months and have no current or recent leg injuries, you could be qualified to participate.  All testing and training will take place in the Human Performance and Muscular Assessment Laboratories of the Exercise and Sport Sciences Building at Texas Tech University.  Financial compensation is not available.  For more information, contact Matt Stock.

 

Test-retest reliability of peak and average concentric and eccentric isovelocity squat force

Healthy men between the ages of 18-30 that are experienced in lower-body strength training are needed for a study examining test-retest reliability statistics for a novel squat force testing device. The study requires three visits to the Muscular Assessment Laboratory, and each session will take roughly 60 minutes. For more information, contact Matt Stock.

 

 

 

 

 

Faculty members within the Department of Health, Exercise, and Sport Sciences have research agendas that answer important questions related to the physical development of young athletes, baseball performance, adaptations to strength training, the non-invasive assessment of muscle function, and many other exciting 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 unique experiments.  Graduate and undergraduate students in our department have the opportunity to make valuable contributions to our research studies.

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.

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:
