A) Are your feet healthy? Even people who try to cover all the bases—avoiding fattening foods, hitting the gym and wearing sunscreen—may not be able to answer yes. Doctors say people often ignore persistent but minor foot complaints, which can later develop into bigger problems, like lower back pain. Some common foot problems can mask underlying issues that are correctable if addressed early. Tender feet might be a sign of a pinched nerve, for example, or bunions (肿) might stem from weak arches. Other foot illness, such as sores that don’t heal, can point to a more serious condition, such as diabetes.
B) Podiatrists (足部医生) say foot illness are a growing problem as more people get physically active. Running marathons, for instance, puts added pressure on the feet and can worsen existing issues that might be caused by genetics or poor footwear choices. Feet also must bear the burden from the growing numbers of people who are overweight or obese.
C) Many people don’t wear shoes with proper support, which is especially harmful for active athletes, says Leslie Campbell, a spokeswoman for the American Podiatric Medical Association, a professional organization. "We see more young children coming in because they play sports like soccer and wear cleats, which are rigid, don’t absorb shock, cause fatigue and should be worn as little as possible," she says. Dr. Campbell, a podiatrist at Presbyterian Hospital in Allen, Texas, recommends soccer players not wear cleats off the field and be sure to warm up adequately before playing so the joints are supple in the shoe.
D) Other sports, including football, basketball and tennis, require constant, quick side-to-side movements that increase the risk of ankle sprains. And long-distance running can cause overuse problems like heel spurs, pinched nerves in the ankle and excessive rolling of the foot, which is known as over-or under-pronation.
E) People can check for pronation problems by looking at the bottoms of their shoes. Uneven wear means the foot isn’t landing properly, which can cause a collapsed arch and lead to lower back pain, says Eugene Charles, a New York-based practitioner of applied kinesiology (运动学) , an alternative medicine that combines elements of chiropractic (脊椎神经) , physical therapy and other disciplines. Orthotics is usually recommended in this case, he says.
F) Achy feet shouldn’t just be explained away by old age or standing a lot, says Dr. Charles. Rubbing the feet after a long day should feel good. But if the feet are tender to the touch, this could reveal an underlying problem such as overworked muscles or weak arches. Often the wrong shoes are to blame, so try footwear with more support.
G) Sometimes a foot problem starts in another part of the body. If the bones in the ankle make a crackling sound when the joint is rotated, this could mean a major muscle located in the calf and foot, called the tibialis posterior (胫骨后肌) , needs to be strengthened, Dr. Charles says. A weak tibialis posterior can cause tendon (肌腱) problems and shin splints. Standing on one foot or doing calf stretches and heel raises can strengthen the muscle.
H) Elevating the feet whenever it is convenient is a good practice because it alleviates pressure, Dr. Charles says. Epsom-salt soaks and foot massages feel good, but usually don’t address actual problems. If people need a soak every day for their feet to feel normal, there may be something wrong, he says. Going barefoot isn’t always a good idea. Shedding shoes on grass or on the beach can strengthen certain muscles, Dr. Campbell says. But walking barefoot on hard surfaces, which don’t provide support, can cause muscle strain and misalignment. Regular stretches and exercises can strengthen muscles and help prevent some common foot problems.
I) Before getting out of bed, wake up the foot muscles. Sit with your feet extended and angle the toes toward your head and then away from it. This works the Achilles tendon and fascial band. Rolling your foot over a tennis ball stimulates nerve endings and protects from injury. Picking up small objects like marbles strengthens muscles in the toes and foot. Calf stretches strengthen major muscles in the lower leg that affect the foot. Wrapping a rubber band around the toes and then expanding the toes outward supports foot muscles.
J) To prepare for a vacation that will involve lots of walking, Dr. Charles recommends getting the feet in shape by starting to take walks a month before the trip and gradually ramping up the workout length. He suggests alternating the speed—walk very slowly for one block, then fast for another—to work different muscles and strengthen the foot overall.
K) Some foot illness can signal bigger problems, for which a podiatrist or orthopedic surgeon should be consulted. For example, pain in the big toe can be a sign of gout, a form of arthritis. Sores that don’t heal can indicate diabetes and abnormal blood-glucose levels or peripheral artery disease. And soreness or a burning sensation in the ball of the foot can signal a pinched nerve.
L) Bunions and hammertoes are common illness that are painful and usually indicate larger structural problems. Bunions are the bony bumps that form at the base of the big toe and hammertoes are toes with an abnormal bend in the middle joint. These can signal that the foot isn’t receiving enough support, either because of ill-fitting shoes like heels, or genetics that cause the foot to be too mobile.
You need to change the speed of your walk in order to exercise different muscles of your body.
选项
答案J
解析 根据J段最后一句He suggests alternating the speed—walk very slowly for one block，then fast for another—to work different muscles and strengthen the foot overall，Dr．Charles建议在步行时调整速度，慢步行走一段时间后可以进行一段时间的快步行走，这样可以让你不同部位的肌肉得到锻炼，同时加强整体的足部运动。因此可以将题干定位至该句。
