With regard to sideline concussion testing, the effect of fatigue associated with different types of exercise on postural control is unknown.
To evaluate the effects of fatigue on postural control in healthy college-aged athletes performing anaerobic and aerobic exercise protocols and to establish an immediate recovery time course from each exercise protocol for postural control measures to return to baseline status.
Counterbalanced, repeated measures.
Research laboratory.
Thirty-six collegiate athletes (18 males, 18 females; age = 19.00 +/- 1.01 years, height = 172.44 +/- 10.47 cm, mass = 69.72 +/- 12.84 kg).
INTERVENTION(S): Participants completed 2 counterbalanced sessions within 7 days. Each session consisted of 1 exercise protocol followed by postexercise measures of postural control taken at 3-, 8-, 13-, and 18-minute time intervals. Baseline measures were established during the first session, before the specified exertion protocol was performed.
MAIN OUTCOME MEASURE(S): Balance Error Scoring System (BESS) results, sway velocity, and elliptical sway area.
We found a decrease in postural control after each exercise protocol for all dependent measures. An interaction was noted between exercise protocol and time for total BESS score (P = .002). For both exercise protocols, all measures of postural control returned to baseline within 13 minutes.
Postural control was negatively affected after anaerobic and aerobic exercise protocols as measured by total BESS score, elliptical sway area, and sway velocity. The effect of exertion lasted up to 13 minutes after each exercise was completed. Certified athletic trainers and clinicians should be aware of these effects and their recovery time course when determining an appropriate time to administer sideline assessments of postural control after a suspected mild traumatic brain injury.
关于场边脑震荡测试，不同类型运动相关的疲劳对姿势控制的影响尚不清楚。
评估疲劳对进行无氧和有氧运动方案的健康大学生运动员姿势控制的影响，并确定每种运动方案后姿势控制指标恢复到基线状态的即时恢复时间进程。
平衡、重复测量。
研究实验室。
36名大学生运动员（18名男性，18名女性；年龄 = 19.00 ± 1.01岁，身高 = 172.44 ± 10.47厘米，体重 = 69.72 ± 12.84千克）。
参与者在7天内完成2次平衡测试。每次测试包括1个运动方案，随后在3分钟、8分钟、13分钟和18分钟时间间隔进行运动后姿势控制测量。在第一次测试中，在执行指定的运动方案之前建立基线测量。
平衡误差评分系统（BESS）结果、摇摆速度和椭圆摇摆面积。
我们发现每种运动方案后，所有相关测量的姿势控制均下降。运动方案和时间之间对于总BESS评分存在交互作用（P = .002）。对于两种运动方案，所有姿势控制测量指标在13分钟内恢复到基线。
通过总BESS评分、椭圆摇摆面积和摇摆速度测量，无氧和有氧运动方案后姿势控制受到负面影响。每次运动完成后，疲劳影响持续长达13分钟。在确定疑似轻度创伤性脑损伤后进行场边姿势控制评估的合适时间时，认证的运动训练师和临床医生应了解这些影响及其恢复时间进程。
