Accelerometer-Determined Physical Behavior Metrics And Their Associations With Sarcopenia Among Oldest-Old Adults, Eric M. Eberl
Accelerometer-Determined Physical Behavior Metrics And Their Associations With Sarcopenia Among Oldest-Old Adults, Eric M. Eberl
Masters Theses
INTRODUCTION: Sarcopenia is a loss of muscle function and muscle mass which frequently occurs among the oldest-old adult population (aged 85+ years). The analysis of accelerometer-determined physical behavior volumes and patterns of oldest-old adults might provide novel insights into the associations with sarcopenia and its components. METHODS: A total of 145 participants in the primary sample and 87 participants in the subsample with a mean age of 88.2 (2.5) years from the Health, Aging, and Body Composition study cohort provided cross-sectional data of handgrip strength, appendicular lean mass, gait speed, and accelerometry. Probable, confirmed, and severe sarcopenia were assessed based …
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 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) …
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 …
