Endurance Athletes Ebook
Stress injury of the femoral neck results from repetitive abnormal stresses on the hip, and may be seen in runners, other endurance athletes, and military recruits. Fatigue fractures represent stress injury developing in structurally normal bone. These injuries often occur on the medial aspect of the femoral neck, where compressive forces are pronounced, but can also develop on the outer aspect, where tensile forces predominate 2,10-14 . Radiographs may be negative, at least early in the clinical course. MRI reveals localized bone marrow edema along the medial femoral neck in early stress injury. With progression, a low signal-intensity line may be visualized perpendicular to the medial cortex, surrounded by bone marrow edema. This reflects the actual fracture with endosteal callus. At this stage, radiographs may reveal a corresponding sclerotic line, perpendicular to the cortex (Fig. 1) 13,15 .
Iron is essential not only for proper hemoglobin function but also for the production of cellular energy, immune function, and brain function. It is especially important for learning and memory in growing children. Iron supplementation may also be necessary in endurance athletes, pregnant women, those taking arthritis medication regularly, and for those taking an aspirin a day. Later in life, it becomes less essential. Low iron levels are known to increase the likelihood of infection and can increase the generation of free radicals in tissues. Low levels are also responsible for poor wound healing.
Range of motion, muscle strengthening, and endurance exercises focus on reducing pain and maintaining joint function. Aerobic exercises include walking, stationary bicycle riding and aquatic exercise. 2. Strength and endurance training. Muscle disuse from inactivity quickly erodes strength. Isometric exercises that do not involve joint motion are the most commonly used in osteoarthritis.
Often these patients are deconditioned, and one must start at a low work load to avoid flaring symptoms. Water exercise classes, especially in heated pools, tend to be effective. Other exercises to consider include walking, riding stationary bicycles, and engaging in low-impact aerobics. Exercise programs that incorporate elements of muscle stretching, muscular endurance, and aerobic fitness tend to be most effective. Regardless of the specific exercise program, it must be approached slowly and consistently to produce optimal results.
