“…The vast majority of studies (n = 53) reported no effect of compression on heart rate [2, 5, 7-9, 13-15, 27, 35, 47, 49, 50, 52, 56, 64, 87, 92, 94, 97, 99-108, 114, 115, 117, 123, 124, 126, 127, 131, 135, 136, 148, 156, 162, 163, 165, 171, 177-183], while 12 studies [22,31,36,119,122,132,133,164,173,175,176,184] reported positive effects of compression, and three studies [14,166,185] reported negative effects. Blood pressure was largely not influenced by compression, with seven studies [106,107,123,156,162,165,186] reporting no change and only two studies [122,173] reporting a positive effect. There is some evidence to suggest compression garments positively influence cardiac output, with three studies [106,173,176] reporting positive effects of compression and two studies reporting no effect [15,156].…”
