Short- And Moderate-Duration Static Stretching Do Not Decrease Vertical Jump Performance When Performed With A Complete, Sport-Specific Warm-Up, Alvin M. Goh

Theses : Honours

Background: Research has shown that static stretching may improve muscle flexibility as well as minimise soft tissue injury. However, recent studies have recommended the removal static muscle stretching from pre-exercise routines due to its deleterious effect on physical performance. Nonetheless, research has shown a duration-dependent effect of static stretching, with total muscle stretch durations < 45 s having little influence on subsequent sporting performance. Furthermore, some evidence indicates that muscle stretching may not influence performance when a sport-specific warm-up follows the stretching component. However, this protocol has not been implemented in most studies.

Purpose: The purpose of the present study was to compare the effects of shorter (5 s) and longer (30 s) periods of static stretching to dynamic stretching on vertical jump performance in sub-elite athletes when the stretches are completed early in a complete pre-exercise routine. It …

Resting Energy Expenditure Using Indirect Calorimetry In Individuals With Moderate To Low Burns: A Pilot Study Of Associated Factors, Patient Acceptability And Comparison With Predictive Equations, Janica Bell

Theses : Honours

Background: Energy expenditure increases following a burn injury. The extent of hypermetabolism is dependent on a range of factors including burn total body surface area. Moderate to low burn injuries (< 15% TBSA) represent majority of hospital admissions for burn injuries however, their energy expenditure remains unpublished. While indirect calorimetry (IC) is the gold standard for determining energy requirements, less accurate predictive equations are often used in practice. Acceptability of IC from a burn patient perspective has not been published.

Aim: To describe the resting energy expenditure (REE) of patients with a moderate to low burn injury using IC; compare measured REE to predictive equations; and determine the patient acceptability of IC.

Methods: Demographic, anthropometric and dietary data were collected for five male and three female burn patients. REE was determined using indirect calorimetry (Ultima CPX) and five predictive methods (Schofield, Harris-Benedict, Toronto and the Ireton-Jones …
