Effects of Foam Rolling on Aerobic Performance
Get PDFPhysical activity causes microtrauma, fascial scar tissue, and other muscle damage leading to delayed onset muscle soreness (DOMS). Foam rolling (FR) has been shown to be an effective cool down technique to reduce DOMS. Currently, there is no research regarding the use of FR as a warm-up for aerobic training. PURPOSE: The purpose of the study was to examine the effect of various warm-up techniques on aerobic performance in Division III soccer players. METHODS: Seven male and nine female Division III soccer players completed the study. Baseline measurements of each participant were taken including height, weight, and body composition. Participants performed the Multistage Fitness Test three times with 1 week in between trials. Before each test, participants completed a warm-up of either FR, dynamic stretching (DS), or a combination of both (FR/DS). RESULTS: There was no significant difference in VO2max between the warm-up techniques (FR: 44.44 ± 5.11 mL/kg/min, DS: 43.34 ± 4.84 mL/kg/min, FR/DS: 43.91 ± 5.10 mL/kg/min). CONCLUSION: FR or FR/DS can be as effective as DS when used for a warm-up prior to aerobic performance
Hemispheric Effects in Facial and Emotional Perception
Get PDFThis study investigated the effect of hemispheric field upon the perception of normal and Thatcherized (faces with inverted mouth and eye features) faces. The prevailing evidence is that faces are processed either locally in parts (eyes, nose, mouth) or globally by the relationships between parts. Emotional processing theories include the valence hypothesis (positive emotions processed in left hemisphere, negative in the right), the approach-withdrawal hypothesis (approach emotions processed in the left hemisphere, withdrawal in the right), and the right hemisphere hypothesis (all emotions processed in the right hemisphere) (Adolphs, Jansari, & Tranel, 2001; Quaranta, Siniscalchi, & Vallortigara, 2007; Natale, Gur, & Gur, 1983). Faces were presented on PowerPoint slides at 12 respective angles (0 to 330 degrees rotation) for 0.20 seconds in either the left or right visual field. Normal faces were generally seen as happier than distorted faces, and normal faces differed significantly based on hemisphere and angle (F(11)=2.17, p=.01), as did distorted faces (F(11)=4.55, p=.00) with a Tukey’s post hoc revealing significant differences between angles 60 and 300 (F(1)=20.61, p=.00). There was a general trend of misidentifying emotions when the mouth was tilted away from the focal point, indicating that the mouth may be essential in identifying happiness
The New PSU Honors Program - Explained
No full textWe will explain the new PSU Honors Program, including: 1) benefits to the university, 2) how students get in, 3) benefits for the students, and 4) roles (all voluntary) for faculty and professional staff. We would also like input from faculty and staff for future program evolution. Short presentation with much time for Q&A
