Psychosocial Correlates Of Physical Activity In Children And Adolescents In A Rural Community Setting, Kelly Crimi†, Larry D. Hensley‡, Kevin J. Finn‡
International Journal of Exercise Science
The purpose of this study was to evaluate the relationships between selected psychosocial factors and the physical activity behaviors of children (grade 4-8) and adolescents (grades 9-12) in a rural community setting. The Children’s Physical Activity Scale (CPAC)was used to measure the psychosocial factors of physical activity, The Physical Activity Questionnaire-Children (PAQ-C), and Physical Activity Questionnaire-Adolescents (PAQ-A) were used to measure the physical activity behaviors of the 167 participants. Results indicated that male and female physical activity behaviors were not significantly different. However, physical activity declined with age [F(8,147) = 5.44, p < 0.05, ES = 0.23]. All psychosocial factors were significantly correlated with physical activity in youth with the single highest correlation for males being “liking of exercise” (r = .61) and the highest correlation for females was “liking of games and sports”(r = .44). Stepwise regression analyses identified three subscales (liking of games and sport, liking of exercise, and parental support) in a significant prediction model of physical activity in both genders. The results indicate that children's physical activity is associated with a variety of psychosocial variables that represent import predisposing and reinforcing factors.

Predictors Of Adl Disability In Culturally Diverse Older Adults, Fernanda Winchester†, Rebecca Ellis‡, Maria Kosma‡, Katie E. Cherry‡, Priscilla D. Allen‡, Pamela A. Monroe‡, Robert H. Wood‡

The purpose of this study was to utilize the disablement pathway model to examine the contribution of physical function, dyspnea, and pain to disability in activities-of-daily-living (ADL) in culturally diverse older adults. Participants were 51 older adults (age = 69.0 years ± 9.7; 76.5% African-American, 51.0% < high school education, 52.9% < $20,000 annual income) from an urban community center and an independent living housing facility for seniors. Participants completed the Functional Status Index (FSI), which provides ratings of need for assistance (FSIA) and pain (FSIP) with ADL, the Continuous Scale Physical Functional Performance 10-item Test (CS-PFP10), and an analog dyspnea scale. Hierarchical multiple regression analyses revealed that facility, physical function, pain, and dyspnea accounted for 50.5% of the variance in disability and that pain (β = .43, p < .01) and physical function (β = -.39, p < .01) were the only significant predictors. In the second model, facility, dyspnea, and pain explained 27.6% of the variance in physical function, and facility (β = .39, p < .01) and dyspnea (β = -.26, p = .05) were the only significant predictors. Based on the disablement pathway model, physical functional improvement and pain prevention and management should be targeted when designing culturally appropriate strategies for delaying disability and maintaining independent life.
Anthropometric And Physiological Predictors Of Flat-Water 1000 M Kayak Performance In Young Adolescents And The Effectiveness Of A High Volume Training Camp., Scott C. Forbes†, Daniel L. Fuller†, Joel R. Krentz†, Jonathon P. Little†, Phillip D. Chilibeck‡
Anthropometric And Physiological Predictors Of Flat-Water 1000 M Kayak Performance In Young Adolescents And The Effectiveness Of A High Volume Training Camp., Scott C. Forbes†, Daniel L. Fuller†, Joel R. Krentz†, Jonathon P. Little†, Phillip D. Chilibeck‡
International Journal of Exercise Science
Our purpose was to determine the relationship of anthropometric and physiological variables with 1000m flat-water kayak (K1000) performance. A secondary purpose was to determine the effectiveness of a high volume training camp. High performance young adolescent kayakers (n=13, 8 males, 5 females, 15±1 yrs) participated in this study. Testing before and after the 3-4 week training camp included anthropometric measurements (height, sitting height, arm span, and body mass), strength (1-RM: bench press and bench pull), flexibility (sit and reach), and an incremental kayak ergometer test to determine peak oxygen uptake (VO2peak) and anaerobic threshold, and an open water K1000 time …

Short-Term Changes In Ldl Density And Lipoprotein Particle Number In Trained Men After 3 Different Modes Of Exercise, Jonathan M. Oliver
International Journal of Exercise Science: Conference Proceedings
Short-Term Changes in LDL Density and Lipoprotein Particle Number in Trained Men After 3 Different Modes of Exercise Jonathan M. Oliver, Steven E. Martin, Shawn P. Glowacki, Wade Womack, John S. Green, FACSM, and Stephen F. Crouse, FACSM, Texas A&M University, TX 77843, (Sponsor: S. F. Crouse) PURPOSE: To determine the short-term changes in LDL density and lipoprotein particle number after three different modes of exercise in trained men. METHODS: Twenty seven subjects were randomly assigned to complete either (resistance [RE], endurance [EE], or combination resistance/endurance [CE]) exercise. Fasting blood samples were obtained 24 h before (baseline) and 24 h …

Changes In Pparδ Protein Content Following Acute Aerobic Exercise In Human Vastus Lateralis Muscle., Nicholas P. Greene, Mats I. Nilsson, Bradley S. Lambert, Steven E. Riechman, James D. Fluckey, Stephen F. Crouse
International Journal of Exercise Science: Conference Proceedings
PPARδ is a transcription factor which functions in the regulation of lipid and glucose metabolism, and may be implicated as a therapeutic target for several metabolic diseases. Exercise training has previously been shown to increase PPARδ protein content, but the response of PPARδ to acute exercise is not yet understood. PURPOSE: To explore changes in PPARδ protein content following an acute bout of aerobic exercise in untrained obese adults. METHODS: 8 men and 4 women participated in the study. Subjects’ mean age, weight, VO2MAX (Bruce treadmill GXT), and body composition (DEXA) were 44 yr, 93.2 kg, 28.2 mL/kg/min, and 40.5% …

Influence Of Caloric Expenditure On Postprandial Triglyceride And Glucose Responses Following A High-Carbohydrate Meal, James Rowe, Heidi Bistrup, Kelley Henry, Melinda Villarreal, Kyle D. Biggerstaff, Vic Ben-Ezra
International Journal of Exercise Science: Conference Proceedings
Purpose: To examine the effects of aerobic exercise expending 350 and 700 kcal of energy on postprandial triglyceride (Tg) and glucose responses following a high carbohydrate (CHO) meal. Methods: Non-active individuals (n=9 women/4 men; age=22.8±3.7 yrs; Ht=169±10.4 cm; Wt=75.7± 22.4 kg; BMI=26.1±5.8 kg/m2; VO2 max=34.1±6.9 ml/kg/min) completed three trials in a random order: 1) control trial, 2) single exercise session expending 350 kcal (EX350), and 3) single exercise session expending 700 kcal (EX700). Exercise consisted of treadmill walking at 60% VO2 max until 350 and 700 kcal of energy had been expended. The control session consisted of seated rest. The …
The Increase In Renal Sodium Excretion In Response To Angiotensin Ii Infusion In Exercised Female Rats Is Dependent On A Rise In Renal Perfusion Pressure, Karmon Janssen
All Graduate Theses, Dissertations, and Other Capstone Projects
Prior studies in this lab have shown that chronically exercised female spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats excrete a greater amount of sodium in response to angiotensin II (Ang II) infusion than do sedentary rats. The current study determined if the difference in renal sodium excretion persisted when the renal perfusion pressure (RPP) was held constant. Female SHR and female WKY rats were separated into sedentary and exercised groups at 4 weeks of age. The exercise group voluntarily exercised for at least eight weeks using an exercise wheel and time/distance monitor. At 13 weeks of age or older, …
