The purpose was to determine the effect of Naproxen in attenuating the symptoms (muscle soreness level) and signs (plasma CK activity and muscular strength decrement) of delayed onset muscle soreness (DOMS). Twenty subjects were randomly assigned Naproxen (500 mg BID) or placebo in a double-blind, crossover design. Two testing phases, each 8 days in duration, were separated by a washout period of 7 days. Eccentric single-leg exercises were performed on Days 1, 3 and 4 to induce DOMS in the quadriceps muscles. Perception of muscle soreness, plasma CK, and knee extensor torque were evaluated throughout each phase. Following the eccentric exercise, plasma CK levels were similarly elevated in both Naproxen and placebo conditions. After DOMS had developed, Naproxen reduced the perception of soreness on Day 3 when muscle soreness was highest. Following treatments with Naproxen, peak quadriceps torque during leg extension at 60$ sp circ$/s was higher compared to placebo, however at higher velocity (180 and 300$ sp circ$/s) peak muscle torques were similar. The data indicate that therapeutic doses of Naproxen do not prevent CK release into the plasma but decreases the perception of muscle soreness and positively influences quadriceps peak torque.

The purpose of this study was to examine performance characteristics of physically awkward children during the recovery portion of the sprinting stride, and compare them to those of non-awkward children. The dependent variables (length of functional phases, and length and method of power flow at the hip and knee joints) were calculated using the digitized coordinates of selected body landmarks from a high-speed camera film. Statistical analysis was used to interpret the dependent variables, as well as compare them across ability levels. / The results revealed no significant differences between ability levels in the dependent variables examined. The findings from this study allow for physically awkward children to be characterized as having abilities for success during the recovery of the sprinting stride. Identifying abilities represents an approach that focusses on a positive view into physical awkwardness, a view which has traditionally been negative. (Abstract shortened by UMI.)

Leg ulceration negatively affects quality of life (QOL). The relationship between important clinical attributes such as ulcer severity, pain and health related quality of life (HRQL) is poorly understood. The Wilson and Cleary model of Health Related Quality of Life (WC model) is a guiding framework that links clinical measures to QOL. Thesis Objectives: I describe the relationship between ulcer severity, comorbidity, etiology and pain and HRQL. Methods: An integrative mixed-methods approach was used: a systematic review of studies that examined the relationship between clinical variables and HRQL or QOL as outlined in the WC model (n=22); a review of studies (n=11) that compared the HRQL of persons with leg ulcers to population normative scores; and, an analysis of the relationship between clinical factors and HRQL in a cohort of 564 persons with venous leg ulcers drawn from two randomized control trials. Results: There is empirical support for the causal linkages between disease severity, symptoms, function, health perception and QOL that comprise the causal pathway as outlined in the WC model. Venous ulcers are associated with a poor quality of life, and numerous aspects of functioning are impaired, in particular physical function. In 564 individuals with venous ulcers, pain was present in 78.8%. Those younger than 65 years were 1.5 times more likely to be in the higher pain group compared to those 65 and older. Physical HRQL was significantly impaired. Predictors of poor physical HRQL included venous-arterial ulcers, a more severe ulcer, arthritis and a higher level of pain. Poor mental HRQL was associated with the younger age group, a comorbid condition and a higher level of pain. Increasing ulcer duration negatively affected mental state, but the findings were of borderline significance. Conclusion: The WC model is a clinically useful framework to select variables to represent HRQL and to base hypotheses about causal associations between clinical variables and QOL. Future research should focus on specifying the measurement models to represent disease severity, symptom status and functional status. Clinically the WC model is a useful bedside heuristic to explore the impact on leg ulceration on daily life and wellbeing. / Thesis (Master, Nursing) -- Queen's University, 2010-01-16 13:11:38.045
