The Effects Of Stress On American Football Overhand Throw Accuracy, Cale Anderson
The Effects Of Stress On American Football Overhand Throw Accuracy, Cale Anderson
All NMU Master's Theses
The American overhand football throw is a highly scrutinized position because of all the different kinds of stress both physical and psychological that are put onto those players. The current study sought to develop a formula using psycho-emotional and physical variables to predict the performance of an American overhand football throw under stressful/non-stress situations. Participants were tested on two days. The stress situation is where tennis balls were thrown, and the subject did not know where they were going to throw. The non-stressed was a 3 step drop without knowing what target they were throwing at and these conditions were …

Biomechanical Adaptations To An Implemented Ramp Angle In Recreational Alpine Skiers, Stephanie R. Moore
All NMU Master's Theses
Most ski boot-binding complexes have a negative ramp angle. This angle is not regulated or reported in the alpine ski industry, but may influence skier balance and pressure control. Thus, joint coordination and center of pressure maintenance in alpine skiers (n = 19) was investigated during simulated ski squat and balance tasks with increasing binding ramp angles (0°, 1°, 2°). Greater sagittal plane center of pressure excursions were observed with ski-booted tasks compared to barefoot conditions during squats and balance simulations. Squat tasks performed on skis resulted in more uncoordinated knee-ankle movement, however, this effect was reduced with the highest …

Postural control and joint position sense are essential for safely undertaking leisure and professional activities, particularly at high altitude. We tested whether exposure to a 12-day trek with a gradual ascent to high altitude impairs postural control and joint position sense. This was a repeated measures observational study of 12 military service personnel (28±4 years). Postural control (sway velocity measured by a portable force platform) during standing balance, a Sharpened Romberg Test and knee joint position sense were measured, in England (113m elevation) and at 3 research camps (3619m, 4600m and 5140m) on a 12-day high altitude trek in the …
