Abstract

Broatch, JR, Bishop, DJ, Zadow, EK, and Halson, S. Effects ofsports compression socks on performance, physiological, andhematological alterations after long-haul air travel in elite femalevolleyballers. J Strength Cond Res XX(X): 000–000, 2018—The purpose of this investigation was to assess the merit ofsports compression socks in minimizing travel-induced performance,physiological, and hematological alterations in elitefemale volleyball athletes. Twelve elite female volleyballers(age, 25 ± 2 years) traveled from Canberra (Australia) toManila (Philippines), and were assigned to 1 of 2 conditions;compression socks (COMP, n = 6) worn during travel or a passivecontrol (CON, n = 6). Dependent measures includedcountermovement jump (CMJ) performance, subjective ratingsof well-being, cardiovascular function, calf girth, and markers ofblood clotting, collected before (224 hours, CMJ; 212 hours,all measures), during (+6.5 and +9 hours, subjective ratingsand cardiovascular function), and after (+12 hours, all measuresexcept CMJ; +24 hours and +48 hours, CMJ) travel.When compared with CON, small-to-large effects wereobserved for COMP to improve heart rate (+9 hours), oxygensaturation (+6.5 hours and +9 hours), alertness (+6.5 hours),fatigue (+6.5 hours), muscle soreness (+6.5 hours and +9hours), and overall health (+6.5 hours) during travel. Aftertravel, small-to-moderate effects were observed for COMP toimprove systolic blood pressure (+12 hours), right calf girth(+12 hours), CMJ height (+24 hours), mean velocity (+24hours), and relative power (+48 hours), compared with CON.COMP had no effect on the markers of blood clotting. Thisstudy suggests that compression socks are beneficial in combatingthe stressors imposed by long-haul travel in elite athletes,and may have merit for individuals frequenting long-haultravel or competing soon after flying
