The degree requirements consist of the University Core Curriculum, major core requirements, elective courses in areas of specializations, a foreign language, and an internship. Our structured weight management programs teach needed skills for living a healthier, more active lifestyle. The internship is a time-limited, supervised period of health education activities carried out in a health-oriented organization. Topics will include diseases of the cardiovascular, pulmonary, and metabolic systems. Internship Eligibility Health majors are eligible to apply for an internship if they: Get in the same position you did for head lifts. It's a habit, a routine, something we do every day.

All About Exercise Machines

When these enzymes enter the bloodstream at higher than normal amounts, they are said to be elevated. Because the liver's functions effect every part of the body, inflammation in this organ may cause stomachache, nausea and vomiting.

Your doctor can determine the cause of liver distress with the help of blood tests and a comprehensive health history. Loss of appetite, nausea and vomiting, diarrhea and stomach pain could be the flu, but if your liver enzymes are elevated it could be a case of hepatitis A. The hepatitis A virus also typically causes jaundice. It is spread by fecal-oral contamination, a result of poor bathroom hygiene or food contamination.

The virus is shed in the stool of infected persons. Hepatitis A is a self-limiting disorder; you may need only rest and plenty of fluids to get over it. Infection with the hepatitis B or C viruses may cause chronic illness and damage to the liver that occurs over time.

The Illinois Department of Public Health reports that hepatitis C is spread by blood, putting health care workers, IV drug users and those who received blood transfusions prior to at highest risk. Hepatitis B can be prevented by vaccines. A healthy liver aids the digestion of fats and proteins, regulates sex hormones, breaks down toxins in the bloodstream and removes excess red blood cells.

Chronic alcohol abuse taxes the liver, causing accumulation of fatty deposits, which become inflamed, leading to alcoholic hepatitis. The American Liver Foundation states that 35 percent of heavy drinkers develop this condition. If drinking continues, healthy liver tissue is gradually replaced by non-functioning scar tissue, a process known as cirrhosis. Abdominal swelling and tenderness, loss of appetite and nausea may characterize alcoholic liver disease.

Obesity, high cholesterol, high blood pressure and type 2 diabetes are risk factors for non-alcoholic steatohepatitis. The disorder generally follows the same course as alcoholic liver disease, however patients may be non-drinkers. Since a treadmill is moving under you, the impact may be slightly less than that.

One more thing to keep in mind: Treadmills can pose a real balance challenge for new exercisers or those who haven't worked out in a while, says Matthew Vukovich, exercise physiologist and associate professor at South Dakota State University. These machines pack a little less punch on the joints, and either can be a good alternative to the treadmill, says Vukovich. Because you use them in a standing position, you're using lots of muscle mass, so the calorie burn rate is still pretty high.

Elliptical machines with arm components can further increase the numbers of calories you burn, says Stamford. All our experts agree that the stationary bike offers the workout with the least impact on the joints. People with knee pain are often steered toward these bikes, since the impact of body weight is not a concern as it is on a treadmill, elliptical trainer, or stair stepper. But to avoid knee strain, you must make sure the bike is adjusted to fit your body, Vukovich says. Most people sit too low, meaning their knees flex too much as they pedal.

This can put too much pressure on the knee and result in soreness, warn Vukovich. The stationary bike is a less intense calorie-burner than some of the other machines. You'll need to pedal four miles to burn calories, says Alexander. Rowers are more advanced cardiovascular machines.

Because you must push with the legs while you pull with the arms, rowers require coordination. They also you require you to engage your core abdominal muscles to support and protect your back. Because they use so many muscle groups, rowers burn lots of calories. But this machine has several red flags for a beginning or unfit exerciser. Extra weight often comes with back pain , and this is not a machine you want to use if you have back issues, he says. Choose a machine that feels right.

If impact is a problem, the stationary bicycle may be a better choice than the treadmill. More muscle use equals more calorie burn. The basic rule of thumb is that the machine that exercises the greatest muscle mass burns the most calories.

There's a flip side of that coin, too: If you're a beginner, using more muscles means getting fatigued sooner -- which will result in burning fewer calories. Try using a pre-programmed workout that includes variations in speed and intensity. Or vary those factors yourself during your workout.

There are so many things you can do to make it more interesting. Work out for time. Instead of forcing yourself to stay on one piece of equipment when you're bored or uncomfortable, just give yourself a time goal at the gym, says Stamford. For example, give yourself 30 minutes to get your workout in.

Then break it up any way you want — say, 10 minutes each on the treadmill and bike, followed by 10 on the elliptical machines.
