When both arms and legs Are used in exercise blood is pumped to peripheral blood vessels in the arms As Well As the legs. This increased flow the peripheral blood vessels Are More involved May prevent the blood pressure from rising too much during the exercise so there is no additional Strain on the heart. The practical implications of such research Are significant. Runners for example would Benefit from More use of their arms. An addition to the runner s fitness routine might be an occasional run with hand weights. Backing off from running a bit and adding hand weights could have a beneficial result Gulin said. The research also indicates the usefulness of such things As rowing machines Cross country skiing machines and Stair climbing devices in which the legs Are used to mount stairs As the arms pull on overhead handles. Also walkers should consider swinging their arms. Indeed the serious Walker s exaggerated gait in which the arms pump up and Down is clearly beneficial. With a Little imagination you can find Many combinations of exercise routines that can employ the arms. The stationary cyclist might pedal Tor a while and then do an upper body weight training routine followed by calisthenic More bicycling and a stint on a rowing machine. Joggers might pause for push ups or conclude a run with a few minutes on a rowing machine. Before Gulin and his colleagues began their study they indulged in some self experimentation to validate their proposed research protocol. Gutin underwent the 60-Minule Arm and leg routines. As a Pilot subject my legs did t become As exhausted and my arms did t become As exhausted As they did when used alone he said. But Over All i Felt i had received a much More Complete  what to Drin when you exercise in summer s heat by William Stockton new York times he heat of summer will soon burs upon us raising the question about what to drink in connection with exercise. The obvious answer of course is water. It has met Man s biological needs for thousands of years and still seems adequate to the task. But a tour of grocery store aisles or a perusal of sports Magazine advertising raises another question what about the sports drinks products of the latest physiological research a kind of High tech water if we Are to perform Al our Best perhaps we need to swig one of these special beverages. The most famous is gatorade made by the Quaker Oats co., which eschews the term sports drink and has dubbed us product a performance beverage Ross laboratories has its exceed a fluid replacement and Energy  but for the recreational athlete seeking fitness who Seldom works out Lor More than 30 minutes or an hour the sports drinks Are not necessary. Waler is quite adequate. The critical consideration in hot weather is to make sure you drink enough water. If the taste is not objectionable add a Pinch of Salt. The sports drinks become useful Lor the competitive endurance athlete lha marathoner the trial halon competitor of a Long distance bicycle racer. These beverages have been formulated from the Start for serious athletes said Robert Murray a physiologist and group manager of the exercise physiology Laboratory at gatorade. That s the whole reason for their being. The weekend athlete who consumes Glorado does so because he likes the association with a serious athlete and because he likes the  what is unclear and a Point of Contention among physiologists is at what Point in prolonged exercise water becomes inadequate and some Type of sports drink becomes essential. Two physiological considerations Are at work loss of fluids and Salt trom the body through sweat and the steady burning of Energy by tha body. Vigorous exercise on a hot Day can cause the body to lose from one to three quarts of fluids from sweating each hour. Most of the water comes trom the blood and blood volume diminishes. On a hot Day within 90 minutes you could lose 3 percent of body weight through sweating and tha clinical signs of dehydration could appear said or. Ethan Nadel a physiologist at lha John b. Pierce foundation Laboratory at the Yale University school of Medicine. These symptoms include lightheadedness dizziness a tendency to faint and even nausea. Sweat also carries Salt out of the body reducing the level of Salt in tha blood. When you drink pure water after exercise. The water is quickly taken up by the digestive system and enters the blood. But the water contains no Salt. Added to the blood it has the effect of decreasing the Overall concentration of Salt in tha blood. As the blood passes through the kidneys they sense the lowered Salt concentration and misinterpret it As a sign that the blood contains too much water. The kidneys begin removing water from the blood in order to get the Salt concentration Back to Normal. The water is passed from the body As Urino. Thus instead of replenishing the lost fluids drinking pure Wale can actually induce additional loss of fluids from the body. That is the reasoning behind the Salt added to sports drinks. Drinking slightly Salty water instead of pure water adds both fluid and Salt to the blood preventing the unwanted urine output. But for the recreational athlete even someone coming off an hour Long fitness run the Lack of Salt in the water 19 not serious. Additional urination can be compensated for by drinking additional water. The proper balance of fluid and Salt in the blood is soon achieved. The problem arises in the endurance athlete who drinks pure water alter an hour of intense exercise but still has two three or even More hours of exercise remaining. The Lack of Salt in his drinking water can become critical. There is an easy solution one half Gram of Salt added to a quart of water is sufficient. However drinking Salty water is not generally considered one of life s Little pleasures and that is where the sports drink people make their bid. Through food science they disguise some of the Salty taste. A second consideration is the loss of glucose that occurs with prolonged exercise. When we eat carbohydrates the digestive process converts them to glucose which the Ceils bum to generate Energy. Excess glucose is stored As Glycogen and then converted Back to glucose As needed. With prolonged exercise the Glycogen is depleted and the body can literally run out of readily available fuel dramatically decreasing performance marathoners indulge in pasta Ealing binges the night before a Competition to Load the body up with Glycogen. But the typical recreational athlete who eats a balanced diet need not be Overly concerned with Glycogen depletion. Nadel calculates that it takes about three hours of intense exercise for the body to run out of fuel. However the sports drink makers contend that reduction of Glycogen can become significant enough even after less than an hour of exercise to degrade performance. You can deplete the carbohydrate stores in your Muscles in 30 minutes during High intensity  said or. Keith Wheeler a physiologist who is Ross laboratories manager of education and research. Someone doing a 10-Kilometer race can deplete Glycogen stores in the  so gatorade contains about 6 percent glucose exceed about 7 percent. The stars and stripes Page 15
