The purpose of this investigation was to determine the effects of varying facemask reinforcement and visor tint on peripheral visuomotor abilities in collegiate football players. Division I NCAA football players ( = 14) completed two peripheral visuomotor experiments: (1) Varying facemask reinforcement, (2) Varying visor tinting. In experiment 1, participants were tested under the following conditions: baseline (no helmet; BL), helmet + light (HL), helmet + medium (HM), helmet + heavy (HH), and helmet + extra heavy (HXH) reinforced facemasks. In experiment 2, participants were tested under the following conditions: baseline (no helmet; BL), helmet only (HO), helmet + clear (HCV), helmet + smoke-tinted (HSV), and helmet + mirror-tinted (HMV) visors. For each condition, a 60 s peripheral visuomotor test was completed on a Dynavision D2 visuomotor board. For experiment 1, the BL peripheral reaction time (PRT) was faster than all facemask conditions ( < 0.05). Furthermore, PRT was impaired with the HXH compared to HL ( < 0.001), HM ( < 0.001), and HH ( = 0.001). Both HH and HXH resulted in the potentiation of PRT impairments in the outermost and inferior peripheral visual areas ( < 0.05). In experiment 2, BL PRT was faster than all helmeted conditions ( < 0.05). Additionally, PRT was slower in HSV ( = 0.013) and HMV ( < 0.001) conditions compared to HO. HMV resulted in slower PRT in all peripheral areas ( < 0.05) while PRT was impaired only in outer areas for HSV ( < 0.05). Wearing protective football headgear impairs peripheral visuomotor ability. Lighter reinforced facemasks and clear visors do not appear to exacerbate impairment. However, heavier reinforced facemasks and tinted visors further decrease visuomotor performance in outer and inferior visual areas, indicating a potential need for considerations of on-field player performance and safety.
本研究的目的是确定不同的面罩加固方式和面罩颜色对大学橄榄球运动员外周视觉运动能力的影响。美国大学体育协会第一分区的橄榄球运动员(n = 14)完成了两项外周视觉运动实验:(1)不同的面罩加固方式,(2)不同的面罩颜色。在实验1中,参与者在以下条件下接受测试:基线(不戴头盔;BL)、头盔+轻型(HL)、头盔+中型(HM)、头盔+重型(HH)和头盔+超重型(HXH)加固面罩。在实验2中,参与者在以下条件下接受测试:基线(不戴头盔;BL)、仅戴头盔(HO)、头盔+透明(HCV)、头盔+烟熏色(HSV)和头盔+镜面色(HMV)面罩。对于每种条件,在Dynavision D2视觉运动板上完成一次60秒的外周视觉运动测试。在实验1中,基线外周反应时间(PRT)比所有面罩条件下都快(p < 0.05)。此外,与HL(p < 0.001)、HM(p < 0.001)和HH(p = 0.001)相比,HXH使PRT受损。HH和HXH均导致最外周和下外周视觉区域的PRT损伤增强(p < 0.05)。在实验2中,基线PRT比所有戴头盔的条件下都快(p < 0.05)。此外,与HO相比,HSV(p = 0.013)和HMV(p < 0.001)条件下的PRT较慢。HMV导致所有外周区域的PRT较慢(p < 0.05),而HSV仅在外周区域使PRT受损(p < 0.05)。佩戴橄榄球防护头盔会损害外周视觉运动能力。较轻的加固面罩和透明面罩似乎不会加剧这种损害。然而,较重的加固面罩和有色面罩会进一步降低外周和下视觉区域的视觉运动表现,这表明可能需要考虑场上运动员的表现和安全。
