Reducing thrombotic risks in video gamers: investigating the benefits of walking and compression sleeves on blood hemodynamics.

ABSTRACT

With the growing popularity of video gaming, deep vein thromboses are increasingly being reported in gamers. This study aimed to compare the effects of lower leg graduated compression sleeves and a 6-min walking break during prolonged gaming on blood flow and hemodynamics in competitive sport players to help mitigate this risk. Ten healthy gamers (19.6 ± 1.2 yr old; 9 men) consented to participate in this mixed-model crossover design study that consisted of three visits. In visit 1, participants engaged in continuous 2-h video game play wearing no compression (continuous). Visits 2 and 3 involved 2-h play wearing compression sleeves (compression) and 2-h game play interrupted at 1 h by a 6-min walk (walk). Doppler ultrasound measurements of the left popliteal artery were taken at 30, 60, 90, and 120 min, to record vessel diameter, blood flow velocity, and blood flow volume. Participants completed a survey to assess their perception of each approach. There was a significant interaction between conditions for blood flow and blood velocity (P = 0.01, P < 0.001). Post hoc analysis demonstrated a greater decrease in blood flow and blood velocity in the continuous group compared with the walk group at the 90-min mark (P = 0.04, P = 0.01). No differences were found between the compression and walk groups or between the continuous and compression groups (P = 0.42, P = 0.69). No interactions were observed in diameter, mean arterial pressure, or heart rate. This study suggests that incorporating a 6-min walk every 60 min during prolonged gaming is advisable to counteract the negative effects on blood flow hemodynamics.NEW & NOTEWORTHY A 6-min light-intensity walking break during gaming can effectively combat the adverse effects of prolonged sitting, surpassing compression garments. Prolonged sitting reduces blood flow velocity, potentially leading to deep vein thrombosis (DVT). Compression sleeves help, with superior results after a 6-min walk at 60 min. Although compression stockings offer moderate improvements, a 6-min active break proves more effective. These findings offer promising interventions for gamers' health, initiating guidelines to mitigate DVT risk during gaming.
