Sports injuries are injuries that happen to athletes participating in sporting events. In many cases, these types of injuries are due to overuse of a part of the body. For example, runner's knee is a painful condition associated with running, while tennis elbow is a form of repetitive stress injury at the elbow. Other types of injuries, such as a broken bone, can be caused by hard contact with something.
运动损伤是指运动员在参加运动项目时发生的损伤。很多情况下，这些类型的伤害是因为过度使用了身体的某部分。例如，跑步膝这种疼痛通常与跑步有关，而网球肘则是因为肘部重复性应力损伤。其他类型的损伤，如骨折，可能是由与某物的剧烈接触引起的。

Injuries are a common occurrence in professional sports, and most teams have a staff of trainers and close connections to the medical community. Controversy has arisen at times when teams have made decisions that could threaten a player's long-term health for short-term gain.
损伤在职业运动中很常见，多数运动队都有训练人员，并与医学界保持密切联系。当运动队为了短期利益做出可能威胁球员长期健康的决定时，有时会引发争议。

Sports injuries can be classified as either traumatic or overuse injuries. Traumatic injuries account for most injuries in contact sports such as soccer, rugby and American football. This is of course due to the dynamic and high collision nature of these games. These injuries range from bruises and muscle strains to fractures and head injuries.
运动损伤可分为创伤性损伤和疲劳性损伤。在足球、橄榄球和美式足球等接触性运动中，创伤性损伤占多数，这当然是由于这些项目的运动属性和高碰撞属性。这些损伤包括瘀伤、肌肉拉伤、骨折和头部损伤。

A bruise is damage to small blood vessels which causes bleeding within the tissues. A muscle strain is a small tear of muscle fibers and a ligament sprain is a small tear of ligament tissue. The body's response to these injuries is the same in the initial five-day period immediately following the incident - inflammation. Inflammation is characterized by pain, localized swelling, heat, redness and a loss of function. Inflammation is the first phase of healing, and typically lasts for around five days. However, too much of an inflammatory response can mean that the healing process will take longer, and a return to activity is delayed. Sports injury treatments are intended to minimize the inflammatory phase of an injury so that the overall healing process is accelerated.
瘀伤是对小血管的损伤，会导致组织内出血。肌肉拉伤是肌肉纤维的一种小撕裂，关节扭伤是韧带组织的一种小撕裂。身体对这些损伤的反应在损伤事件发生后的头5天内是相同的——出现炎症。炎症的特点是疼痛、局部肿胀、发热、发红和功能丧失。炎症是愈合的第一阶段，通常持续5天左右。然而，炎症反应过多可能意味着愈合过程需要时间更长，活动的恢复将被推迟。运动损伤治疗的目的是尽量减少损伤的炎症期，从而加速整个愈合过程。
