Effects Of Pre-Determined Barbell Hip Thrusting Surface Height On Motor Unit Recruitment And Activation Patterns, Abigail Renae Mccarty
Effects Of Pre-Determined Barbell Hip Thrusting Surface Height On Motor Unit Recruitment And Activation Patterns, Abigail Renae Mccarty
Masters Theses
Several variations of the barbell hip thrust that manipulate stance width and resistance type rather than surface height to better isolate muscle groups that act as prime movers for the exercise have been previously researched. The purpose of this study was to identify the effects of hip thrusting surface heights on neuromuscular activity in the gluteus maximus (GM), vastus lateralis (VL), and biceps femoris (BF). Twelve averagely fit, resistance trained individuals were recruited for this study. Participants completed a dynamic warm-up followed by 10 repetition max (RM) testing of the barbell hip thrust. Prior to trials, root mean square (RMS) …
A Descriptive Study On The Strike Characteristics Between A Heavy Bag, Focus Mitts, And Thai Pads, Tirzah Ruth Dacio Talampas
A Descriptive Study On The Strike Characteristics Between A Heavy Bag, Focus Mitts, And Thai Pads, Tirzah Ruth Dacio Talampas
Masters Theses
The purpose of this study was to compare vGRFs during continuous strikes to three different modalities, a free-standing heavy bag, focus mitts, and Thai pads, and the punching velocities under these conditions. It was hypothesized for punches that punching velocity would be higher in punches thrown at a heavy bag, punching velocity would be faster in rear-hand punches, vGRFs would be higher in the lead leg compared to the rear leg of a punch at impact, and vGRFs would be higher in heavy bag punches compared to focus mitt punches. For kicks it was hypothesized that vGRFs of dominant and …
Effects Of Different Recovery Methods On Hangboard Performance In Rock Climbers: A Pilot Study, Daniel Tyler Ehrich
Effects Of Different Recovery Methods On Hangboard Performance In Rock Climbers: A Pilot Study, Daniel Tyler Ehrich
Masters Theses
The purpose of this study was to determine whether static stretching, dynamic shakes, or repeated contractions would promote the greatest retention in performance in hangboard training within a given period of time. Five volunteer intermediate climbers from the Liberty University rock climbing team were instructed to suspend themselves from a 20mm ledge on a hangboard until voluntary failure while time was recorded. After failure, subjects performed one of three different recovery methods and a control in randomized order for two minutes in alternating fifteen-second intervals. Upon finishing recovery, subjects would hang from the same ledge and have their time recorded …
The Application Of Biomechanical Technology In Sports, Timothy Leckrone
The Application Of Biomechanical Technology In Sports, Timothy Leckrone
Senior Honors Theses
Technology in biomechanics encompasses eight major categories: artificial optical devices, anthropometry, timing devices, electrogoniometry, electromyography, dynamometry, inertial tracking systems, and modeling and simulation. As technology improves and becomes more accessible to the general population, it becomes easier to implement biomechanical technology into sports. For each area of focus, biomechanical technology has numerous points of current application or potential application. This application has benefit in injury prevention, technique improvement, rule enforcement, performance optimization, overall health and condition analysis, sports timing, and product development and testing. This thesis examines each area in turn as well as the various tools implemented in order …
The Role Of Hamstring Contraction During Running: An Analysis, Theodore Hu
The Role Of Hamstring Contraction During Running: An Analysis, Theodore Hu
Senior Honors Theses
The hamstring muscle group, spanning the posterior aspect of the proximal lower limb, generates large amounts of contractile force during running. Researchers have examined this power generation within different phases of the stride cycle. Forces generated by the hamstrings hold implications for both running efficiency and the role of strengthening for injury prevention. The goal of this review is to examine the hamstring’s unique physiology as a bi-articular muscle, its role in running stride, various training philosophies, and the specific impact on running economy contributing to overall running performance. The summation of research presented shows that the hamstring muscle group …
