Vertical Jump Performance No significant differences were observed in vertical jump performance either prior too or post completing a 15 minute steady state run between garment conditions. The variables analysed include the mean and peak concentric force, jump height and flight time. A small effect size (ES = 0.2) was observed in mean and peak concentric force following the steady state run when wearing correctly fitted compression tights. These findings are similar to that of Ali et al., (2010), who reported no difference in jump height or peak power between garment conditions following a 40 minute sub maximal run (~80% VO2max). Rugg and Sternlicht, (2013) report a significantly greater mean counter-movement jump height in graduated compression tights following 15 minutes of steady state running. The difference in finding between this and the present study may be related to the method of jump height assessment (Vertec vs force platform). Furthermore, countermovement jump has been shown to improve (or attenuated a decline) following various exercise modalities when wearing compression clothing (Jakeman et al., 2010; Kraemer et al., 1996; Kraemer et al., 1998). Future research should identify if vertical jump height is improved during athletic performance. Data in this area is lacking and would ultimately identify if any identifiable benefit is gained, does this translate into ‘on field’ performance i.e. peak and mean jump height of ‘blockers’ during volleyball game. Time to Exhaustion The time to exhaustion data presented in this study is generally aligned to previous findings, in that compression garments have no statistical or practical significance on running time to exhaustion at vVO2max (Goh et al., 2011; Sperlich et al., 2010). Goh et al., (2011) investigated running performance undertaken at the same exercise intensity, with SKINS long tights, reporting a similar compression profile (13.6 ± 3.4 and 8.6 ± 1.9 mmHg at the calf and thigh respectively) supports the current finding that time to exhaustion is not improved. A worthwhile point is that whilst at 10°C, TTE was not improved, a small effect size (ES = 0.48) was reported at 32°C when wearing full length SKINS compression tights.
