Seventy percent of motor sports athletes report low back pain. Information on the physical capacity of race car drivers is limited. The purpose of this study was to compare the maximum trunk extensor and flexor strength of elite race car drivers and physically active controls. Thirteen elite race car drivers and 13 controls were measured in concentric mode for maximal trunk flexion and extension at 60° x s(-1) and 120° x s(-1). Peak torque (mean ± s) at 60° x s(-1) in trunk extension was 283 ± 80 N x m in the drivers and 260 ± 88 N x m in controls (P > 0.05). At 120° x s(-1), drivers produced peak torques of 248 ± 55 N x m compared with 237 ± 74 N x m for controls (P > 0.05). Peak torques in flexion were less than in extension for both groups (60° x s(-1): drivers 181 ± 56 N x m, controls 212 ± 54 N x m, P > 0.05; 120° x s(-1): drivers 191 ± 57 N x m, controls 207 ± 48 N x m, P > 0.05). Individual ratios of flexion to extension forces exhibited ratios of 0.88 (60° x s(-1)) and 0.93 (120° x s(-1)) for controls and 0.66 (60° x s(-1)) and 0.77 (120° x s(-1)) for drivers (60° x s(-1): P > 0.05; 120° x s(-1): P > 0.05). The maximum strength performance capacity of the trunk muscles of elite motor sport athletes competing in long-distance racing did not differ from that of anthropometrically matched and physically active controls.
百分之七十的赛车运动员报告有下背痛。关于赛车手身体能力的信息有限。本研究的目的是比较精英赛车手和有身体活动的对照组的最大躯干伸肌和屈肌力量。13 名精英赛车手和 13 名对照组以 60°/s 和 120°/s 的角速度进行最大躯干屈伸测试。60°/s 时躯干伸肌的峰值扭矩（均值±标准差）在司机组为 283±80N·m，在对照组为 260±88N·m（P＞0.05）。在 120°/s 时，司机组产生的峰值扭矩为 248±55N·m，而对照组为 237±74N·m（P＞0.05）。两组的屈伸峰值扭矩均低于伸肌（60°/s：司机组 181±56N·m，对照组 212±54N·m，P＞0.05；120°/s：司机组 191±57N·m，对照组 207±48N·m，P＞0.05）。对照组屈伸力比为 0.88（60°/s）和 0.93（120°/s），司机组为 0.66（60°/s）和 0.77（120°/s）（60°/s：P＞0.05；120°/s：P＞0.05）。参加长距离比赛的精英赛车运动员的躯干肌肉最大力量表现能力与人体测量匹配和有身体活动的对照组没有差异。
