Islam & Sports

Islam & Sports
The 24-year-old wore a hijab -- a scarf which covers the hair and neck -- along with leggings and long sleeves, but still outpaced her more scantily-clad rivals to win gold for Bahrain.

How do you feel looking your wife halfnaked on the track?
 Ruqaya Al Ghasara said "Wearing conservative clothes has encouraged me. Wearing a veil proves that Muslim women face no obstacles and encourages them to participate in sport. This is a glory to all Muslim women."


Sport Science & Physical Education: Heat Stroke

Sport Science & Physical Education: Heat Stroke

Heat stroke ia true medical emergency. In this case, all of the heat mechanisms have failed and the body temperature has risen to the point where the brain's regulating mechanism has been knocked out. Body temperature may go as high as 107F to 109F. The symptoms of heat stroke are red, hot skin,lack of sweating and usually loss of consciousness. Get someone with heat stroke to the emergency room immediately, where an ice bath, ice packs or a cooling blanket can be used to help lower the body temperature. Someone with heat stroke could die very quickly without treatment.

Dietician

Allied health care professionals who are trained specifically in the field of nutrition are called dieticians.An athlete's performance can be enhanced with the aid of sound nutrition,and the dietician is the resident expert in this fields.For example, during the rehabilitation process, the dietician may be consulted when an athlete is being treated for a psychological problem in the form of an eating disorder. Athletes being rehabilitated for physical problems may also exhibit nutritional problems that the dietician may assist in managing.Most dieticians are employed by a hospital.Often, they serve as consultants to athletes and teams on dietary matters.The dieticians areas of expertise in sport include weight gain and loss,bulimia, anorexia nervosa, pre-competition meals,proper hydration, and nutritional supplementation.

Range of Motion

Defining Range of Motion

Range of motion(ROM) can be defined as the movement of body part through a particular joint’s complete,unrestricted.,normal motion. Normal joint movement is dictated by the following:
1. The type of joint involved
2. The shape and surface of the joint
3. The degrees of freedom of motion allowed at the particular joint
4. The contractile and noncontractile tissues surrounding the joint.

Normal ROM accurs smoothly when active muscle contraction produces muscle shortening. As the muscle shortens, the bone on which the particular muscle inserts is acted on, yielding physiological joint motion. Normal ROMs have been established for each joint of the body. ROM is categorized as being active, active-assisted, or passive. Active and passive components can be subdivided into physiological and accessory components.

Active ROM

Active range of motion(AROM) is the motion produced by active muscle contraction. Forces generated by the muscle that are primarily responsible for a given motion cause the body segment to which the muscle’s origin. AROM can occur with the assistance of gravity, with the effect of gravity eliminated, or against gravity. AROM must be assessed as the body part moves against gravity and it provides a true measurement of the muscle and tendon tissue’s effect on joint movement.

Active-Assisted Range of Motion(AAROM)

AAROM is motion in which the body segment being moved is assisted through at least part of the normal ROM. Motion must be assisted because of a breakdown in normal ROM. Assistance can be offered by gravity, an uninvolved body part, an object or device,or an external force.

Passive ROM

Passive range of motion(PROM) is movement that takes place with no active muscle assistance.it is usually performed by another person who takes the body part through the ROM manually. The athlete may also perform PROM manually on him or herself.
