Hardiness: An Examination Of Psychological Characteristics Of Participating In High Intensity Interval Training, Matthew Vezzani Jan 2015

Hardiness: An Examination Of Psychological Characteristics Of Participating In High Intensity Interval Training, Matthew Vezzani

WWU Graduate School Collection

CrossFit, a form of high intensity interval training (HIIT), has grown in popularity (Thompson, 2013). Some physiological benefits of CrossFit have been documented (O’Hara et al., 2013), yet psychological effects have not been investigated. Hardiness has been linked to the performance of elite athletes (Sheard, 2009). Hardy individuals tend to have a strong sense of commitment, control and challenge (Kobasa, 1979) that enables athletes to create opportunities from stressful situations (Maddi, 2006). The CrossFit training style (“What is Fitness?”, 2002) may promote the development of commitment, control and challenge. The purpose of the study was to see if CrossFit training …


The Effect Of Maternal Traits On Rearing Success In Pacific Harbor Seals (Phoca Vitulina Richardsii), Erin Rose D'Agnese Jan 2015

The Effect Of Maternal Traits On Rearing Success In Pacific Harbor Seals (Phoca Vitulina Richardsii), Erin Rose D'Agnese

WWU Graduate School Collection

Reproductive success in species that care for their young is affected by the rearing strategy utilized. Otariids are known as income breeders, because they continue to forage during a rearing time of about a year while leaving pups on land; their rearing success is related to attendance patterns. On the other end of the continuum, large phocids are described as capital breeders, fasting on shore during a rearing time from 4 to 50 days. Their rearing success is based on maternal body mass. Harbor seals (Phoca vitulina) don’t appear to follow either of these two strategies fully and …


The Effect Of Deep Slow Breathing On Pain-Related Variables In Osteoarthritis, Kalee L. (Kalee Lynn) Larsen Jan 2015

The Effect Of Deep Slow Breathing On Pain-Related Variables In Osteoarthritis, Kalee L. (Kalee Lynn) Larsen

WWU Graduate School Collection

This study evaluated the effect of a six-week deep slow breathing (DSB) program on pain, physical function, and heart rate variability (HRV) in subjects with lower extremity joint pain. Twenty subjects were assigned into training (n=10) and control (n=10) groups. The training group participated in a six-week DSB program consisting of weekly training sessions and at-home breathing exercises. DSB exercises focused on prolonging the exhalation and the pause following exhalation. The Western Ontario and McMaster Osteoarthritis Index (WOMAC) was used to assess pain and physical function and HRV data were obtained pre- and post-intervention. Results revealed no significant interactions between …


The Vocal Breeding Behaviour Of Harbour Seals (Phoca Vitulina) In Georgia Strait, Canada: Temporal Patterns And Vocal Repertoire, Katrina A. (Katrina Anne) Nikolich Jan 2015

The Vocal Breeding Behaviour Of Harbour Seals (Phoca Vitulina) In Georgia Strait, Canada: Temporal Patterns And Vocal Repertoire, Katrina A. (Katrina Anne) Nikolich

WWU Graduate School Collection

During the breeding season, male harbour seals (Phoca vitulina) produce underwater calls used in intra-sexual competition and advertisement. One call type, called a roar, has been documented in every population of this species that has been studied. Because calls vary in structure and temporal patterns among populations, it can be inferred that regional vocal dialects may exist, and that the influence of local environmental and biological conditions may affect the timing of calls. Breeding calls have only been studied in relatively few locations worldwide; however, the effect of ambient noise on the underwater vocal behaviour of harbour seals …


The Effects Of An Isometric Quarter Squat On Countermovement Jump Performance, Mitchell W. Dropp Jan 2015

The Effects Of An Isometric Quarter Squat On Countermovement Jump Performance, Mitchell W. Dropp

WWU Graduate School Collection

The purpose of the study was to determine if an isometric quarter squat was sufficient to elicit postactivation potentiation (PAP) in a countermovement jump (CMJ) for recreationally trained individuals (n = 22). The isometric quarter squat conditioning stimulus consisted of three sets of six second maximal voluntary contractions against a custom made apparatus. The conditioning stimulus was designed to acutely enhance CMJ performance by stimulating PAP, in turn improving indicators of CMJ performance which included eccentric rate of force development (ERFD), mean rate of force development (MRFD), peak rate of force development (PRFD), reactive strength index (RSI), and peak power …
