Talking of tennis injuries, James Ticehurst is back again to follow up from his blog on upper body tennis injuries, to discuss common tennis injuries found in the trunk and lower body.
Research shows that the trunk/spinal areas have the highest injury prevalence out of all the areas of the body tennis can injure. This can double, and sometimes triple the incidence rate over a 5-year summary in comparison to other areas.
The paraspinal, rib and abdominal muscles are there to predominantly stabilise the trunk/spine. The rib muscles sit between the rib bones and attach the ribs to each other. The abdominal muscles are the stabilising muscles of the stomach and trunk.
During the high levels of forces that occur in tennis, especially twisting, they can overload these muscles, over stretching them and causing a muscle strain. If the forces are great enough it can possibly even cause a tear where the fibres have been stretched so much they break apart. This occurs usually as a result of overuse/overload, improper use of the muscle or fatigue.

Equally, you must focus on your flexibility, static stretching and strengthening.
Keeping the muscles of the back flexible is one way to prevent a back strain. Static stretching performed over time will gradually elongate muscles allowing them to be stretched farther before an injury to the muscle occurs.
The individual gradually stretches the muscle to a point of discomfort and then backs off slightly. This position is then held for 30 seconds and repeated. The individual should not move into a position of pain as pain is an indicator of injury to the body.
Strengthening the muscles in and around the spine will also reduce the risk of injury. Exercises that strengthen the core muscles of the trunk should be the focus. This can be achieved through a variety of exercises that focus on sustaining either an isometric or concentric contraction for the muscles most involved in flexion, extension, and rotation of the spine.
Groin muscle strain: a groin muscle strain occurs in athletes that require a quick change in direction and explosive movements. The groin muscle is a muscle the sits in the inner thigh and can be either the primary hip flexor muscles and/or the hip adductor muscle group (group of five muscles that contract to bring the leg in and across the body).
A strain to a muscle is caused when the muscles are overstretched or overloaded. In this case, it can happen in several ways including a strong kick of a ball without warming up, a quick stretch during a lateral movement, or a fall in sports.
The thigh muscle is made up of three sets of strong muscles: the hamstring at the back, the quadriceps at the front, and the groin/adductor muscles on the inside. The quads and hamstrings work together to straighten (extend) and bend (flex) the leg. The adductor muscles pull the legs together. These groups are particularly at risk for muscle strains because they cross both the hip and knee joints.

The knee is stabilised by fibrous tissue called ligaments. There are four cruciate ligaments that hold the knee together, all having different jobs: lateral (LCL), medial (MCL), anterior (ACL) and posterior (PCL).
In tennis with all the bounding and changing direction and at high loads, these ligaments become very stressed. If there is excessive force it will cause a strain or tear of the ligament. If the force is great enough it will cause a full tear or rupture of the ligament.

Tips to avoid this injury:
The meniscus is two C shaped rings of cartilage that sit inside your knee. The main function is to act as shock absorbers and reduce the load going through the knee. They are typically injured when the knee is in a slightly bent and twisted as maximum compression is occurring.

Tips to avoid this injury:
The ankle is supported by two sets of ligaments either side of the foot. Sprained ankles are relatively common in tennis players. Roger Federer, Andy Roddick and Andrew Murray have all suffered sprained ankles. The sudden sideways movements that are required during tennis can cause the ankle to twist, particularly if the surface is slippery or the player is fatigued.
A twisted ankle causes damage to ligaments and other soft tissues around the ankle.
