PVC baseballs of different diameters have significant performance differences, mainly reflected in three aspects: hitting effect, applicable scenarios and safety. The following is a specific analysis:
“打 击 效果” 可 以 翻 译 为 “hitting effect”
A PVC baseball with a larger diameter can provide a greater contact area when hitting, which means that batters can hit the ball more easily and thus increase the success rate of hitting. Meanwhile, a larger ball may exhibit a more stable trajectory during flight, which helps batsmen better control the direction of their hit. The smaller diameter PVC baseball, on the other hand, requires batters to have higher accuracy, as the reduction in contact area increases the difficulty of hitting the ball. However, once hit, the smaller sphere may exhibit a faster flight speed due to a more concentrated mass distribution.
Applicable scenarios
PVC baseballs with larger diameters are more suitable for children’s enlightenment training or fun activities. In children’s enlightenment training, a larger ball helps lower the technical threshold and enables children to master the batting skills more quickly. In fun activities, such as family gatherings or team games, larger balls can enhance the entertainment and participation of the activities. PVC baseballs with smaller diameters are more suitable for professional training or competitions. In professional training, smaller balls can exercise the reaction speed and accuracy of batters. In the competition, using smaller spheres that meet the standards can ensure the fairness and competitiveness of the game.
Safety
PVC baseballs with larger diameters have certain advantages in terms of safety. Because the sphere is large and usually made of soft materials, even if it accidentally hits a part of the body, it can effectively reduce the risk of injury. This is particularly important for children or beginners. While PVC baseballs with smaller diameters are also designed with safety factors in mind, due to their smaller size and potentially faster flight speed, they may increase the risk of injury in some cases. Especially when struck at high speed or in close contact, special attention should be paid to safety protection.
