Abstract

Elite athletes constantly search for the edge over their opponent (Applegate and Grivetti 1997). Indeed, athlete training and competition schedules have resulted in a need to fully recover rapidly from such sessions (Dawson, Gow et al. 2005; Cormack, Newton et al. 2008a; Cormack, Newton et al. 2008b; Elias, Varley et al. 2012; Elias, Wyckelsma et al. 2012; Mooney, Cormack et al. 2012). To overcome the stressors from training and competition, sports compression garments which offer low levels of compression, are commonly used to enhance recovery due to their ease of use, accessibility and affordability. Although a substantial body of research exists investigating compression garment use after a variety of exercise stimuli (Kraemer, Bush et al. 1998a; Kraemer, Bush et al. 1998b; Kraemer, Volek et al. 2000; Kraemer, Bush et al. 2001a; Kraemer, Bush et al. 2001b; Chatard, Atlaoui et al. 2004; Kraemer, French et al. 2004; Duffield and Portus 2007; Duffield, Edge et al. 2008; French, Thompson et al. 2008; Montgomery, Pyne et al. 2008a; Montgomery, Pyne et al. 2008b; Davies, Thompson et al. 2009; Duffield, Cannon et al. 2010; Jakeman, Byrne et al. 2010b; Jakeman, Byrne et al. 2010a; Kraemer, Flanagan et al. 2010; De Glanville and Hamlin 2012), their influence on perceptual, biochemical and performance recovery after actual team sport training and competition, where physical contact is a key component, is lacking. Further, the positive physiological actions of compression garments have mostly been established using a medical style garment, which typically exert a greater volume of compression, in clinical settings. Recent research has sought to determine performance, perceptual and physiological differences when wearing compression garments during exercise that offer varying levels of compression, where the level of compression (low, medium, or high) made no difference to performance or physiological measures (Ali, Creasy et al. 2011; Dascombe, Hoare et al. 2011). It remains unknown if differences in recovery, where the garment is worn exclusively post exercise, would occur between a sports (low level of compression) and medical (high level of compression) style garment in team sport scenarios. Thus this thesis investigated the influence of wearing compression garments on perceptual, biochemical and performance variables following repeat sprint exercise on consecutive days in recreationally trained individuals (Chapter 4); following elite Australian football (AF)training (Chapter 5) and competition (Chapter 6). It also included a comparison between a sports (Spo) and medical (Med) style compression garment. A magnitude based effects approach, using effect sizes and the smallest worthwhile change was used to analyse treatment effects.
