High levels of perceived stress and anxiety among university students are a global concern and are known to negatively influence sleep. However, few studies have explored how stress response styles, like psychological resilience and rumination, might alter these relationships. Using validated tools, perceived stress, anxiety, stress response styles...
Article
While the college years present an ideal time for chronic disease prevention, students often do not seek services or perceive themselves to be at health risk. Researchers at Bowling Green State University have been exploring the health patterns of first-year university students for several years, initially as a health-based research study (August 2...
Article
For university students, alterations in sleep and diet quality are common, and the propensity for weight gain is well established. The role of sleep duration during periods of rapid weight gain is understudied. This study explored the relationships between sleep duration, diet patterns, and body composition in first-year university students. Data c...
Article
This study compared body composition measurements in lean female athletes. The primary objective was to compare the accuracy of percent body fat (%BF) determined by bioelectrical impedance analysis (BIA), air-displacement plethysmography (ADP), and underwater weighing (UWW) in female Division I cheerleaders (n = 10 bases, 6 back-spots, and 12 flyer...

The visual analog scale (VAS) and the general labeled magnitude scale (gLMS) are common response formats for assessing chemosensory sensation. The gLMS is recommended when comparing sensations between individuals whose perceptual experiences vary in a manner that may not be accurately captured on the VAS. This may occur when one group has a wider r...
Thesis
While some previous literature indicates that red pepper (RP) consumption confers weight management benefits, findings have been contradictory. It was posited that these inconsistencies related to poor control over characteristics of the subject population, such as failure to stratify results by habitual use of spicy foods. Consequently, this disse...
Conference Paper
Some studies suggest that capsaicin diminishes orexigenic sensations, but reports are conflicting. One methodological issue potentially accounting for inconsistencies may be differing characteristics of study populations. The purpose of this trial was to contrast responsiveness to capsaicin’s appetitive effects in regular spicy food users (n=13) an...
