“…LDF in the great toe revealed a moderate reduction in the flux values with increasing sub-bandage pressures being significant in the pressure range of 41 to 50 mm Hg. Mayrovitz et al 39 reported similar results in healthy volunteers. These findings cannot be taken as a sign of severe arterial perfusion reduction to the foot, because our toe pressure measurements demonstrate, with increasing subbandage pressure, a slight increase of toe pressure by 6% to 13%.…”

In patients with mixed ulceration, an ankle-brachial pressure index >0.5 and an absolute ankle pressure of >60 mm Hg, inelastic compression of up to 40 mm Hg does not impede arterial perfusion but may lead to a normalization of the highly reduced venous pumping function. Such bandages are therefore recommended in combination with walking exercises as the basic conservative management for patients with mixed leg ulcers.

“…Exercising skin temperatures have typically been higher when covered by CG (Duffield et al 2008;Duffield and Portus 2007;Goh et al 2010;Houghton et al 2009), but without significant effect on sweat rate/mass loss (Duffield et al 2008;Duffield and Portus 2007;Goh et al 2010;Houghton et al 2009) or core temperature (Duffield et al 2008;Goh et al 2010;Houghton et al 2009) in cool to hot environments. Influences on local skin temperature are likely primarily due to the inherent insulation of the garment and associated air, however, pressure per se is known to affect skin perfusion (Mayrovitz and Delgado 1996;Mayrovitz and Sims 2003) and, thus, potentially also heat storage and cardiovascular function. There may be a distinction between effects of pressure per se versus coverage per se, although this has not yet been addressed directly.…”

Pressure and coverage effects of sporting compression garments on cardiovascular function, thermoregulatory function, and exercise performance

et al. 2011

Sporting compression garments (CG) are used widely during exercise despite little evidence of benefits. The purpose of this study was to investigate coverage and pressure effects of full-body CG on cardiovascular and thermoregulatory function at rest and during prolonged exercise, and on exercise performance. Twelve recreationally trained male cyclists [mean (SD) age, 26 (7) years; VO(2 max), 53 (8) mL kg(-1) min(-1)] completed three sessions (counterbalanced order), wearing either correctly-sized CG (CSG; 11-15 mmHg), over-sized CG (OSG; 8-13 mmHg), or gym shorts (CONT). Test sessions were conducted in temperate conditions [24 (1)°C, 60 (4)% relative humidity; ~2 m s(-1) air velocity during exercise], consisting of resting on a chair then on a cycle ergometer, before 60-min fixed-load cycling at ~65% VO(2 max) and a 6-km time trial. Wearing CG (CSG or OSG) did not mitigate cardiovascular strain during mild orthostatic stress at rest (p = 0.20-0.93 for garment effects). During exercise, cardiac output was ~5% higher in the CG conditions (p < 0.05), which appears to be accounted for via non-significant higher end-exercise heart rate (~4-7%, p = 0.30; p = 0.06 for greater heart rate drift in CSG); other cardiovascular variables, including stroke volume, were similar among conditions (p = 0.23-0.91). Covered-skin temperature was higher in CG conditions (p < 0.001) but core (oesophageal) temperature was not (p = 0.79). Time-trial performance (mean power, time taken) was similar with or without CG (p = 0.24-0.44). In conclusion, any demonstrable physiological or psychophysical effects of full-body CG were mild and seemingly reflective more of surface coverage than pressure. No benefit was evident for exercise performance.

“…Other researchers found that SBF increased under low pressure, and then turned to decrease as the pressure exceeding a certain level (Mayrovitz and Marie 1996;Fromy et al 2000). Mayrovitz and Sims (2003) found that the SBF at calf under pressure about 40 mmHg (pressure loaded by an air cast) decreased in the study on effects of ankleto-knee external pressures on skin blood perfusion under compression. In another study, with pressure exerted at lower limb by using sphygmomanometer, it was also found that the SBF at calf turned to decrease under pressure around 40 mmHg (Zhou et al 2008).…”

This paper aims to understand human skin blood flow(SBF) response to external pressure. Alternative pressure loading by using sphygmomanometer was applied on calf while subjects sitting and lying supine respectively; the SBF was observed with laser flowmeter and wavelet analysis was carried out on the SBF signals. The main results are as follows: under pressure of 20mmHg and 40mmHg, SBF obviously increased with sitting posture while that of some subjects turned to decrease under pressure of 40mmHg when lying supine; the frequency of myogenic activity decreased under pressure. It was explained that the SBF change under pressure is the result of balance between the increase through the capillary recruitment and the decrease due to mechanical squashing of small vessels under high pressure; the turning point between increase and decrease depends on the blood pressure inside the arterioles.
