When snow, ice and frigid weather blast into town, watch out for injuries. Winter recreational activities and chores can pose problems for the outdoor enthusiast whose body is not conditioned. electricity notes for class 10 Winter sports like skating, skiing and sledding can cause painful muscle spasms, strains or tears if you’re out of shape. Even shoveling snow the wrong way, clambering awkwardly over snow banks, slipping on sidewalks and wearing the wrong kinds of clothing can lead to spasms, strains and sprains. Simply walking outside in the freezing weather without layers of warm clothing can intensify older joint problems and cause pain. As muscles and blood vessels contract to conserve the body’s heat, the blood supply to extremities is reduced. This lowers the functional capacity of many muscles, particularly among the physically unfit. Preparation for an outdoor winter activity, including conditioning areas of the body that are most vulnerable, can help to avoid injury and costly health care bills. Warm Up Simply put, warming up is essential. gas pump icon When pressed for time, it’s better to shorten the length of your workout and maintain a good warm-up than to skip it and dive right into the workout.

Shoveling Snow Shoveling snow can also wreak havoc on the musculoskeletal system. gas utility boston ACA suggests the following tips for exercise of the snow shoveling variety: • Layer clothing to keep your muscles warm and flexible. • Shoveling can strain “deconditioned” muscles between your shoulders, in your upper back, lower back, buttocks and legs.

Avoid sudden twisting and turning motions. • Bend your knees to lift when shoveling. Let the muscles of your legs and arms do the work, not your back. • Take frequent rest breaks to take the strain off your muscles.
