The Relationship Between Training Load And Injury Or Illness Symptoms Using An Acute And Chronic Workload Ratio In Collegiate Cross-Country Runners, Brennan T. Mickelson

Graduate Student Theses, Dissertations, & Professional Papers

Abstract

Objectives: Examining the relationship between workloads (miles ran) of collegiate cross-country (XC) athletes (n=18) and symptoms of injury or illness over the course of 10 weeks. This can assist sport coaches, athletic performance coaches, and athletic trainers in keeping athletes healthy and furthering adaptation throughout the course of the season, thus improving the team’s overall success during the season.

Purpose: The purpose of this study was to show a relationship between an Acute and chronic workload ratio (ACWR) in miles run and weight lifted, ACWR in miles run grouped by z-scores, weight, age, years of collegiate XC experience, miles …

Changes In Postural Sway Behavior Across The Life Span, Maria M B N R Santos

Graduate Student Theses, Dissertations, & Professional Papers

The present study aimed to investigate human balance control by assessing postural sway on three groups representing three stages of life (6-12, 19-40 and 65-74 years old). There were 14 individuals in each group and they were tested during upright bipedal stance with either eyes open or closed. Focus was given to multiple sway indices representing multi-dimensional features of postural sway in quiet stance and included: the center of pressure area, amplitude, root mean square (RMS), velocity, jerkiness, and sample entropy. Results confirmed that children and seniors swayed more (p<.004), faster (p<.001) and their body sway was shakier (p<.001) than young adults. Seniors also presented faster (p<.006) and shakier (p<.001) sway than children and a more unpredictable pattern of body sway in time (p<.002) than children and young adults. In addition, children presented a more random anterior-posterior sway (p<.034) and a more regular medio-lateral sway (p<.043) than young adults, and a higher synchronization between anterior-posterior and medio-lateral body sway (p<.012) than young adults and seniors. We also observed that postural control of children and young adults becomes relatively more challenged in experimental situations when eyes were closed for most postural indices. In conclusion, this study suggests that multi-dimension posturography is sensitive to detect subtle age-related changes in the postural behavior and each stage of life may have their own signature patterns of postural behavior. Therefore, we expect that quantifications of this nature may be used to assess not only postural instability and fall risk but also to aid the testing of the efficacy of balance interventional protocols.

Hip Flexor Extensibility And Its Correlation To Hip Hyperextension And Lower Back Pain In Dancers, Tessa Richards

Undergraduate Theses, Professional Papers, and Capstone Artifacts

In the world of ballet, flexibility and strength are the keys to success. A leg extended to extraordinary heights is equated with beauty and expertise, whereas a lower height is seen as lesser quality. Dancers are trained from their first ballet lesson to reach their toes to the utmost end of their range of motion, and push themselves beyond the regular restrictions of the human body. Despite the pressure put on dancers to be extremely flexible, tight hip flexor muscles (the rectus femoris and the iliopsoas group) are a common complaint, restricting hip hyperextension (called an arabesque). To compensate for …

Physical Therapists Providing Smoking Cessation Education: Attitudes And Potential In A Rural Setting, James J. Laskin

University Grant Program Reports

The primary objective of this pilot study is to focus on physical therapists practicing in a rural setting; where 65% of the Montana population resides. Physical therapists are a key provider of healthcare service and entry into the healthcare system. In this proposed study we want to 1) assess the current state of smoking cessation being offered by physical therapists, 2) determine the viability of physical therapists to provide smoking cessation counseling based on their knowledge, skills and perceptions, 3) try to understand the patients’ perspective regarding a physical therapist providing these services and 4) identify the barriers to physical …
