The effect of a weighted-vest strength and balance training program on obstructed walking in postmenopausal women

SUMMARY Background: Age related declines in lower extremity strength have been associated with impaired mobility and changes in gait patterns, which increase the likelihood of falls. Since community dwelling adults encounter a wide range of locomotor challenges including uneven and obstmcted walking surfaces, we examined the effect of a strength 11 and balance exercise program on obstructed walking in postmenopausal women. Objectives: This study examined the effect of a weighted-vest strength and balance exercise program on adaptations of the stance leg during obstacle walking in postmenopausal women. Methods: Eighteen women aged 44-62 years who had not engaged in regular resistance training for the past year were recruited from the St. Catharines community to participate in this study. Eleven women volunteered for an aerobic (walking), strength, and balance training program 3 times per week for 12 weeks while 7 women volunteered as controls. Measurements included: force platform dynamic balance measure of the center of pressure (COP) and ground reaction forces (GRFs) in the stance leg while going over obstacles of different heights (0,5, 10,25 and 30 cm); and isokinetic strength measures of knee and ankle extension and flexion. Results: Of the 18 women, who began the trial, 16 completed it. The EX group showed a significant increase of 40% in ankle plantar flexion strength (P < 0.05). However, no improvements in measures of COP or GRFs were observed for either group. Failure to detect any changes in measures of dynamic balance may be due to small sample size. Conclusions: Postmenopausal women experience significant improvements in ankle strength with 12 weeks of a weighted-vest balance and strength training program, however, these changes do not seem to be associated with any improvement in measures of dynamic balance.

Cardiovascular health risk profiling of Niagara Region grade 9 students : implications for elementary curriculum /

The purpose of this study was to determine if Ontario's health and physical education curriculum contributes sufficiently to ensure the health of our children and young adults. To determine the curriculum effect, the health risk profile of Niagara Region's grade 9 students was compared to Canada's adolescent population. All subjects completed a "Heart Health Lifestyle" survey and were measured for height, weight, percent body fat, blood pressure, and total cholesterol and performed the 20-metre shuttle run test as part of their physical and health education classes. The Niagara Region grade 9 population had a healthy risk profile. Aerobic power was inversely related, and cholesterol levels were positively associated to body mass index and percent body fat in the whole group analysis. These results indicate that physical education can offer unique and essential aspects allowing individuals a means to learn and control body movements and keep physically fit while providing protection against modern disease. Ontario's health and physical education curriculum does contribute to the health of our children and adolescents; however, there is a need to implement a stronger mandate for daily vigorous physical activity.

Diversity in the fitness industry : a cross-case comparison /

This cross-case study explored the extent to which two fitness facilities were accommodating diversity with respect to age, ethnicity, gender, social class, sex-role socialization, and persons with a disability among both members and staflf. The sites were purposely chosen in a large city and a smaller city in order to provide as representative an example as possible of health clubs within a small sample population. The interview participants were selected by a combination of stratified, typical case, and snowball sampling strategies. . , .. , The intent of the exploration was a two-fold examination of diversity issues within both the membership and the staff of the organization. Data were collected and analysis was done using a triangulation method involving personal interviews, observations, and facility documentation. The results ofthe study showed that the members and staff at each facility were rather homogeneous in ethnicity, age, social class, physical ability, and physical appearance. From a membership standpoint, the environment of the sites presented the impression of being affordable only to the middle- and upper-middle classes, unwelcoming to the older, less fit, or overweight participant, economically exclusive for youth, and nonaccommodating for people with a disability. With respect to staff, the findings indicated that the fitness facilities purported to be team-oriented in theory, but were hierarchical in practice, with the major decision making being made by the male executives. The paper concludes with the recommendation that students must be given a practical toolkit for dealing with these issues in their postsecondary courses.

Comprehensive school health, the social determinants of health, and the health status of children

As children are becoming increasingly inactive and obese, there is an urgent need for effective early prevention and intervention programs. One solution is a comprehensive school health (CSH) program, a health promotion initiative aimed at educating students about healthy behaviours and lifestyles, which also provides a link between the school, students, families, and the surrounding community. The purpose of this study was to explore the relationship between different components of CSH programs, as well as three determinants of health (gender, social support, socio-economic status), and physical activity, on the aerobic fitness and body mass index (BMI) of children. A newly developed and pilot-tested survey derived from Health Canada's fourpart CSH model (instruction, social support, support services, and a healthy physical environment) was sent to elementary school principals. Data on the gender, physical activity, parental education, and social support levels of students from these schools were gathered from a previous study. Multiple regression procedures were conducted to estimate the relationships between CSH components, the social determinants of health, physical activity, and BMI and aerobic fitness. Results showed that three CSH components were significantly associated with both BMI and aerobic fitness values in children, but accounted for less than 5% of the variance in both variables. Physical activity partially mediated the relationship between the significant CSH components, BMI, and particularly aerobic fitness. Furthermore, the social determinant and physical activity variables played independent roles in aerobic fitness values. No moderating effects of the social determinants were discovered.

A case study of a high functioning autistic female in a games setting

This study detennined whether or not a high functioning autistic girl can develop game structure strategies that may allow her to become an active participant in a game or sport environment. This qualitative case study involved the in-depth observation and description of one high functioning autistic student whose experience in a game setting would be studied. The type of case study carried out was a combination of descriptive and evaluative. This experience was investigated through structured, individual programming. Through on-site observation, journal entries, and hands on instruction, I was able to describe what progress the autistic student made in tenns of skill development. The results of the study demonstrated that a high-functioning autistic female has the potential to develop the necessary motor skills to participate in the chosen sport of basketball. The observation results and field notes contributed to a movement profile which described her habits of body. Teaching strategies and frameworks utilized during the study were described and listed. Insights and commentary are further provided. A thorough examination of autism and games programming is provided in the literature review.

An inquiry into the barriers to participation within the fitness industry for people living with mobility challenges

This qualitative study was designed to inquire about the barriers to participation within the fitness industry for people living with mobility challenges. i\n examination of the insights, stolies~ and experiences with barriers through interviews gi ven by 4 people living with mobility challenges (PMC) formed the core of the research. An analysis of the interviews from the 4 PMC informants was performed at t\\/O levels. First, a content analysis served to identify general and specific categories related to barrier issues within various fitness environments. Secondly, in-depth thematic analyses of the entries related to the insights and stories from the 4 informants which emerged from the content analysis of the data gave rise to fi ve thematic statements. From the thematic statements a fitness industry awareness protocol was created in the fonn of a statement response questionnaire. The protocol, which was given to 4 fitness assessors/trainers, \vas used to provide a snapshot of the fitness industry's readiness to work vvith disability. Throughout the process, the four PNIC informants formed a collaborati vely involved group of coresearchers, adding their voices to the narrative of the fitness-barrier experience. The result of the study suggests that barriers to participation within the fitness industry for PMC exist in various forms and levels of severity. The results also suggest that the fitness industry needs to better prepare their people and environment for working with people with physical disabilities, such as PMC, and provide a more open and positi ve environment for participation. Within the context of any fitness-related environment, recognizing that barriers to participation do exist, and acknowledging and accepting people with disabilities for who they are as indi viduals, will serve to develop a relationship where fitness practitioners and people with disabilities can work towards creating an inviting, inclusive, accessible, and barrier-free fitness environment for all.

Examining experiences that develop responsivity in practitioners

This thesis has been produced to meet the requirements of Brock University's Masters of Education program. It is the result of many peoples' reflections on and beliefs about the act of teaching in today's world. This manuscript is intended to provide the reader with an engaged interpretation of the dynamic field of teaching. In recognizing the ever-changing demands of the profession, this paper serves to provide the reader with a gathering of strategies or paradigm of action which an educator may employ to respond to the demands of his/her complex vocation. This gathering of strategies represents the phenomenon I have examined throughout this study: responsivity. What is it? Is it important for a practitioner to develop? If so, how can it be developed? In no way is this an "answer book" for teachers to adhere to. It is a collection of thoughts and ideas from an array of "insiders" who have experienced the phenomenon of responsivity. It will not provide the reader with immediate answers. What it will offer the reader is a deeper understanding of the related issues and concerns surrounding responsivity.

Training distribution and the acquisition of maximal isometric elbow flexion strength

Twenty-six sedentary, college-aged females were matched and randomly assigned to one of two groups. The massed group (n=13) completed 15 maximal isometric elbow flexion strength trials in one session, while the distributed group (n=13) performed five such contractions on three successive days. After a two-week and three month rest interval, both groups returned to perfonn another five maximal isometric elbow flexion strength trials to assess retention of any potential strength gains. Elbow flexion torque and surface electromyography (SEMG) of the biceps and triceps were monitored concurrently. There was a significant (P < 0.05) increase in strength in both groups from block one (first five contractions) to block four (first retest) and from block one to block five (second retest). Both groups exhibited a similar linear increasing (P < 0.05) trend in biceps root-mean-square (RMS) SEMG amplitude. A significant (P < 0.05) decrease in triceps RMS SEMG amplitude was found between block one and block four for the distributed group. However, a significant (P < 0.05) increase was then found between block one and five for the massed group, and between blocks four and five for distributed group. These results suggest that there is flexibility in resistive exercise schedules. An increase in neural drive to the agonist muscle continued throughout testing. This was accompanied by a reduction in antagonist co activation that was a short-tenn (two weeks) training effect, dissipated over the longer rest interval (three months).

The journey towards comprehensive school health within an aboriginal community

The purpose of this research is to describe the journey towards Comprehensive School Health at two Aboriginal elementary schools. An advocate and a healthy schools committee were identified at both schools and were responsible for developing initiatives to create a healthy school community. A case study was used to gather an in-depth understanding of Comprehensive School Health for the two schools involved. As a researcher, I functioned within the role of a participantobserver, as I was actively involved in the programs and initiatives completed in both schools. The research process included: the pilot study, ethics clearance and distribution of letters of invitation and consent forms. Data collection included 16 semi-structured, guided interviews with principals, teachers, and stupents. Participant observations included sites of the gymnasium, classroom, playgrounds, school environments, bulletin boards as well as artifact analysis of decuments such as school newsletters, physical education schedules and school handbooks. The interviews were transcribed and coded using an inductive approach which involves finding patterns, themes and categories from the data (patton, 2002). Research questions guided the findings as physical activity, physical education, nutrition and transportation were discussed. Themes developed t~rough coding were teacherstudent interactions, cultural traditions, time constraints and professional development and were discussed using a Comprehensive School Health framework.

Edward Mirynech fonds, 1913-1914, 1946, 1952-1957, 1959-1960, 1965-1982, n.d.

Edward Mirynech joined the faculty at Brock University in 1964 as assistant professor of Geology. Edward Mirynech, the son of John and Katherine Mirynech, grew up in St. Catharines, attended Connaught Public School and received his formal education at the University of Toronto. Dr. Mirynech played several critical roles in the early development of the University. In addition to teaching, Dr. Mirynech was also the acting director of the athletics department, a coach for many of the early rowing, hockey and basketball teams and served the University as marshall for the sod turning ceremony for the new DeCew campus in 1965. Dr. Mirynech was instrumental in the founding of the physical education, geography and geological sciences programs. He served as acting chairman in 1968 when the department of geological sciences enrolled its first students. Part of the unique teaching program was the annual field trips to locations such as the Belleville area, extended summer teaching programs held in Trinidad-Tobago and the following year in Iceland. In 1972, the first graduation ceremony ever to be held in the Arctic, at Pond Inlet, NWT, made national news. Three geology students, on a study trip to the Arctic, received their degrees during a special ceremony. Dr. Mirynech was among the faculty team in Pond Inlet, NWT, representing Brock University. Dr. Mirynech retired from teaching in 1985, and passed away in 2004.

The effects of a general excercise program on task self-efficacy and social physique anxiety in older adults

Older adults represent the most sedentary segment of the adult population, and thus it is critical to investigate factors that influence exercise behaviour for this age group. The purpose of this study was to examine the influence of a general exercise program, incorporating cardiovascular, strength, flexibility, and balance components, on task selfefficacy and SPA in older adult men and women. Participants (n=114, Mage = 67 years) were recruited from the Niagara region and randomly assigned to a 12-week supervised exercise program or a wait-list control. Task self-efficacy and SPA measures were taken at baseline and program end. The present study found that task self-efficacy was a significant predictor of leisure time physical activity for older adults. In addition, change in task self-efficacy was a significant predictor of change in SPA. The findings of this study suggest that sources of task self-efficacy should be considered for exercise interventions targeting older adults.

Adult Participants’ Experiences of a Sport Program Implementing the Easy-Play Model: Implications for an Active Lifestyle

The Easy-Play Model is a useful framework for facilitating sport among a diverse group of participants of different ages and ability levels. The model’s focus on de-emphasizing competitiveness in an effort to establish an optimally competitive environment has facilitated positive play experiences. This study investigated the experiences of players who have been a part of a weekly soccer program implementing the Easy-Play Model. In-depth interviews of 8 participants provided insight concerning the benefits and weaknesses of the approach and the notable experiences of the players. Results provided data confirming the model’s effectiveness in facilitating positive social interactions, safe play experiences where injury is generally a negligible concern, and productive opportunities to be physically active through sport. This study of the Easy-Play Model sets the foundation for future research which should further add to our understanding of productive ways to engage people in physical activity through sport.

Back to Basics: Exploring gestural habits as cues for anticipating self-injurious episodes in a child with Autism and Deafness

This research project is a longitudinal qualitative case study. It contributes to an understanding of self-injurious behaviour (SIB) by inviting the reader through the narrative of the lived experience of a fifteen year old child-informant and the network of individuals in his life. The value and importance of a case-study is that it focuses on the authenticity of the experience of living with disability. Through the use of detailed field observations, interviews and photo documents, the study thoroughly explores three main areas: quality of movements, potential cues as pre-cursors to episodes of self-injury, and purposeful communication. The research begins with a review of literature on Autism, Deafness and Self-injury, formulates the research design and orientation of Physical Education, Phenomenology and Semiotics, and then systematically explores four distinct phases in the analytical process. The aim was to explore self-injurious episodes in the child informant in hopes to translate the meaning of the behaviour and potentially utilize this to provide more opportunities for adapted physical activity. The findings reveal distinct patterns of movement cues utilized for different purposes. The implications of the findings are self-injurious episodes in the child informant are preceded by distinct patterns of movement that are potentially communicative. Suggested future direction of the research is expanding the scope to other disabilities for which verbal communication is challenging, and standardizing the translating tools to assist in understanding the communication of movement.

Beyond the Books: Understanding Connections Between Teachers and Pupils From the Perspective of the Student

Using a narrative inquiry approach from the perspective of the researcher’s own experiences, this paper explores the connections that developed with several teachers that facilitated and impacted his own academic and cognitive, affective, and behavioural personal development. Viewed through the analytical lens of Erikson’s theory of psychosocial development, this narrative investigates the potential effectiveness of this model in understanding the lasting and life- altering changes that may be experienced by a student through his or her interactions with memorable teachers. Last, in educational environments today, character and value based curricula are experiencing a resurgence in popularity due to their theoretical applicability for helping students to optimally develop academically, socially, and culturally. With this in mind, a student-based perspective of memorable student–teacher connections may provide a framework for developing more effective means of effectively implementing a character development curriculum.

A Case Study of Disengaged Students' Experiences with Teaching Games for Understanding

The purpose of this research study was to determine if the instructional model, Teaching Games for Understanding (TGfU), would allow for the successful teaching of sport to disengaged female students in Physical Education (PE) classes. An instrumental case study research design was used to determine grade nine female students’ experiences with TGfU, the factors of TGfU that facilitated their engagement, and the ways in which these students resisted engaging in TGfU. Data was collected through a pre and post TGfU unit focus group, participant observation, in-depth interviews, and researcher reflections. Results showed that TGfU caused an increase in the participants’ engagement in PE physically, mentally, and socially/emotionally. Future researchers could structure their entire study holistically and should examine TGfU’s impact on student engagement over the course of an entire semester. Subsequent studies should moreover examine the presence of disengagement within physically skilled students in PE.
