目的是确定在使用不同球杆进行高尔夫挥杆表演期间鞋与天然草界面处发生的旋转扭矩，并确定差点和高尔夫球鞋设计的影响。 24 名高尔夫球手（8 名低杆 0-7 杆；8 名中杆 8-14 杆；8 名高杆 15+）使用 1 号木杆、3 号铁杆和 7 号铁杆进行 5 次击球，同时穿着 3 只鞋：现代 8 毫米金属 7 钉鞋、替代 7 钉鞋和平底鞋。在室外场地的草地覆盖的测力平台上测量前脚和后脚的扭矩。当使用一号木杆、3 号铁杆和 7 号铁杆时，鞋-天然草皮界面处的扭矩与前脚相似，具有最大平均扭矩（Tzmax 17-19 Nm），并且在整个上杆和下杆过程中产生的扭矩约为 40 Nm。使用发球杆、3 号铁杆和 7 号铁杆时，后脚的扭矩小于前脚。后脚的 Tzmax 为 6-7 Nm，产生的扭矩为 10-16 Nm，使用发球杆而不是铁杆时有产生更大扭矩的趋势。使用发球杆时，金属钉鞋比平底鞋可以产生更多的后脚扭矩 (p < 0.05)。对于任何扭矩测量，金属鞋钉鞋和替代鞋钉鞋之间没有显着差异（p > 0.05），尽管金属鞋钉鞋产生的后脚平均扭矩往往更大。低、中、高差点球手穿着金属钉鞋和替代钉鞋时的高尔夫击球结果相似（金属：87%；76%；54%；替代：85%；74%；54%）。水平较高、差点较低的高尔夫球手在使用发球杆时会产生明显更大的后脚扭矩（金属鞋钉：18.2 Nm；替代品：15.8 Nm；p < 0.05）。进一步的研究应考虑低差点和体重较轻的高尔夫球手在使用发球杆期间对后脚鞋草界面的需求。要点 球鞋到天然草皮的扭矩生成是使用发球杆进行高尔夫挥杆的重要组成部分。使用 Tzmax 发球杆、3 号铁杆和 7 号铁杆时，前脚处的球鞋与天然草皮界面处的扭矩相似（约 17-19 Nm），整个上杆和下杆过程中产生的扭矩为 40 Nm。使用 3 号铁杆时，后足处的扭矩小于前足和 7 号铁杆； Tzmax 为 6-7 Nm，扭矩产生为 10-16 Nm，并且在使用发球杆时有更大的趋势。使用发球杆时，低差点高尔夫球手在后脚处产生的扭矩显着高于中或高差点高尔夫球手（P<0.05）。使用发球杆时，天然草坪上的金属钉鞋比平底高尔夫球鞋在后脚处产生的扭矩明显更大。结果对高尔夫球鞋的设计具有影响。
The aim was to determine the rotational torque occurring at the shoe-natural grass interface during golf swing performance with different clubs, and to determine the influence of handicap and golf shoe design. Twenty-four golfers (8 low 0-7; 8 medium 8-14; and 8 high 15+) performed 5 shots with a driver, 3-iron and 7-iron when 3 shoes were worn: a modern 8 mm metal 7-spike shoe, an alternative 7-spike shoe and a flat soled shoe. Torque was measured at the front and back foot by grass covered force platforms in an outdoor field. Torque at the shoe- natural turf interface was similar at the front foot when using a driver, 3-iron and 7-iron with maximum mean torque (Tzmax 17-19 Nm) and torque generation in the entire backswing and downswing approximately 40 Nm. At the back foot, torque was less than at the front foot when using the driver, 3-iron and 7-iron. At the back foot Tzmax was 6-7 Nm, and torque generation was 10-16 Nm, with a trend for greater torque generation when using the driver rather than the irons. The metal spike shoe allowed significantly more back foot torque generation when using a driver than a flat- soled shoe (p < 0.05). There was no significant difference between the metal and alternative spike shoes for any torque measure (p > 0.05), although back foot mean torques generated tended to be greater for the metal spike shoe. The golf shot outcomes were similar for low, medium and high handicappers in both metal and alternative spike shoes (metal: 87%; 76%; 54%; alternative: 85%; 74%; 54% respectively). The better, low handicap golfers generated significantly more back foot torque (metal spike: 18.2 Nm; alternative: 15.8 Nm; p < 0.05) when using a driver. Further research should consider back foot shoe-grass interface demands during driver usage by low handicap and lighter body-weight golfers. Key pointsShoe to natural turf torque generation is an important component in performing a golf swing with a driver club.Torque at the shoe to natural turf interface was similar at the front foot when using a driver, 3-iron and 7-iron with Tzmax (17-19 Nm approx) and torque generation in the entire backswing and downswing of 40 Nm.Torque at the back foot was less than at the front foot when using the driver, 3-iron and 7-iron; Tzmax was 6-7 Nm, and torque generation 10-16 Nm with a trend to be greater when the driver was used.Low handicap golfers generated significantly more torque at the back foot than the medium or high handicappers (P<0.05) when using a driver.The metal spike shoe on natural turf allowed significantly more torque generation at the back foot than a flat-soled golf shoe when using a driver. Results have implications for golf shoe design.
