Like most athletes, you undoubtedly want to lower your chances of incurring an injury while participating in your favorite sport. Injuries decrease the amount of time you can spend in leisure activities, lower your fitness, downgrade competitive performance, and can lead to long term health problems such as arthritis.
There are some general rules for injury avoidance which apply to all sports. Sports scientists suggest that injury rates could be reduced by 25% if athletes took appropriate preventative action.
Coaches and athletes believe that males have higher injury rates than females. Male and female athletes have about the same injury rate per hour of training. Among runners it is considered that training speed is the cause of injuries (Speed Kills) but research indicates that there is no link between speed and injury risk.
The amount of training you carry out plays a key role in determining your real injury risk. Studies have shown that your best direct injury predictor may be the amount of training you completed last month. Fatigued muscles do a poor job of protecting their associated connective tissues, increasing the risk of damage to bone, cartilage, tendons and ligaments. If you are a runner, the link between training quantity and injury means that the total mileage is an excellent indicator of your injury risk. The more miles you accrue per week, the higher the chances of injury. One recent investigation found a marked upswing in injury risk above 40 miles of running per week.
If you have been injured before you are much more likely to get hurt than an athlete who has been injury free. Regular exercises has a way of uncovering the weak areas of the body. If you have knees that are put under heavy stress, because of your unique biomechanics during exercises, your knees are likely to hurt when you engage in your sport for a prolonged time. After recovery you re-establish your desired training load without modification to your biomechanics then your knees are likely to be injured again.
The second predictor of injury is probably the number of consecutive days of training you carry out each week. Scientific studies strongly suggest that reducing the number of consecutive days of training can lower the risk of injury Recovery time reduces injury rates by giving muscles and connective tissues an opportunity to restore and repair themselves between work-outs.
Some studies have shown that athletes who are aggressive, tense, and compulsive have a higher risk of injury than their relaxed peers. Tension may make muscles and tendons taughter, increasing the risk that they will be harmed during work-outs.
Many injuries are caused by weak muscles which simply are not ready to handle the specific demands of your sport. This is why people who start a running program for the first time often do well for a few weeks but then, as they add the mileage on, suddenly develop foot or ankle problems, hamstring soreness or perhaps lower back pain. Their bodies simply are not strong enough to cope with the demands of the increased training load. For this reason, it is always wise to couple resistance training with regular training.
Screening for muscle imbalances is the current cutting edge of injury prevention. The rationale behind this is that there are detectable and correctable abnormalities of muscle strength and length that are fundamental to the development of almost all musculoskeletal pain and dysfunction. Detection of these abnormalities and correction before injury has occurred should be part of any injury prevention strategy. Assessment of muscle strength and balance and regular sports massage can be beneficial in this strategy.
Muscle stiffness refers to the ratio between the change in muscle resistance and the change in muscle length. Muscle stiffness is thought to be directly related to muscle injury risk and so it is important to reduce muscle stiffness as part of a warm up. Research has indicated that only dynamic stretches - slow controlled movements through the full range of motion - decrease muscle stiffness. Static exercises did not decrease muscle stiffness.
This suggest that dynamic stretches are the most appropriate exercises for warming up and not static stretching exercises. Static stretches are perhaps more appropriate for the warm down as they help to relax the muscles and increase their range of movement.
A "trigger point" (TP), which is often caused by the muscle being overloaded, is a thick knot in a muscle which is palpable and tender (even painful to the touch).
Trigger points can be caused by: training errors, inadequate preparation, worn shoes or equipment, poor biomechanics, muscle fatigue, poor flexibility, nutritional factors (vitamin deficiency), psychological factors (lack of sleep, stress).
Treatment of a TP (separating the fibres of the muscle knot) can be achieved by applying direct pressure to the point for 10 to 20 seconds, gradually releasing the pressure and repeating the process 4 of 5 times. The amount of pressure, which will depend on the sensitivity of the TP, can be applied by using one or both thumbs.
A number of treatments may be required but as the sensitivity (pain) of the TP reduces it will become harder to find. If after a couple of treatments the pain does not reduce then you should seek medical advice. Alternative approach to treating a TP is sports massage where petrissage, friction and effleurage techniques can be used to help breakdown the TP.
Trigger points are an early warning to a potential serious injury so checking for TPs is very beneficial. A regular massage is well worth is as the therapists, when conducting a massages, can check for TPs and treat them.
Resistance training can fortify muscles and make them less susceptible to damage, especially if the strength building exercises involve movements that are similar to those associated with the sport. Time should be devoted to developing the muscle groups, strength training, appropriate to the demands of your sport. If you are a thrower then lots of time should be spent developing muscles at the front of the shoulder which increases the force with which you can throw, but you must also work systematically on the muscles at the back of the shoulder which control and stabilise the shoulder joint.
