Fitness is one type of body that is useful for health. If the body in the fitness divided into a few types of exercise that uses each, namely: 1. 2 weight training. Cardio exercise

Use weight training burden as tools to increase muscle contractions can be included in weight training. Muscles that receive the load will experience pressure to exhaustion Achieving a certain point. Strength training itself can be classified based on the weight Used as:

Body burden: Using your own body weight either as part or the whole body burden
Burden-free: Using free weights such as barbells or halter
Load tool: Using electronic or mechanical device connected to the ballast. The purpose of using this tool as backers is generally easier for users to control the weights.

Strength training can also be distinguished on the basis that will be trained muscles, namely:

Use Weight Training Load as tools to increase the muscle contractions can be included in weight training. Muscles that receive the load will experience pressure until it reaches a certain point of exhaustion. Strength training itself can be classified based on the weight used as:

Weight: using his own body as well as some of the burden and the overall weight
Burden-free: using free weights such as Barbell or dumbbell
Load tools: using electronic or mechanical device connected to the ballast. The purpose of using this tool is generally a proponent that allows users to control the weights.

Strength training can also be distinguished on the basis that will be trained muscles, namely:

Chest muscle: Medically known as the pectoral muscles. Types of weight training which include: push ups, bench press.
The back muscles: is medically known as lattismus muscle. Types of weight training which includes: pull ups, chin ups, bench row, deadlift

Abdominal muscles: is medically known as abdominal muscles. Types of weight training which include: sit up, crunch.

Cardio cardio exercises that are the heart. This exercise is more to increase the heart rate without the use of the load. In general, this exercise is to lose weight or simply maintain good health. Type of cardio exercise is very varied ranging from jogging, swimming, cycling to aerobics.

A laboratory morphine vial from the 1880s.

Our bodies produce a small but steady amount of natural morphine, a new study suggests.

Traces of the chemical are often found in mouse and human urine, leading scientists to wonder whether the drug is being made naturally or being delivered by something the subjects consumed.

The new research shows that mice produce the “incredible painkiller”—and that humans and other mammals possess the same chemical road map for making it, said study co-author Meinhart Zenk, who studies plant-based pharmaceuticals at the Donald Danforth Plant Science Center in St. Louis, Missouri.

In the study, researchers injected mice with an extra dose of a natural brain chemical called tetrahydropapaveroline (THP), which humans and mice are known to produce.

Using a tool called a mass spectrometer to analyze the mouse urine, the team was able to tell that THP underwent chemical changes in the body that created morphine, according to the study, published this week in the journal Proceedings of the National Academy of Sciences.

What’s more, the study found that mouse morphine is produced in nearly the same way as the morphine in poppies—the only morphine-making plants known to science.

Morphine a Defense Mechanism?

But “the big question is, What is it for?” Zenk said of the mammal-made morphine.

THP must undergo a complicated, 17-step process in the body to create morphine. Even so, the chemical has evolved twice—in poppies and in mammals—suggesting it’s somehow valuable for survival.

In the well-studied poppy plant, scientists suspect morphine acts as a defense against predators. For instance, a rabbit eating—and thus killing—a morphine-laced poppy may become sluggish, making itself easy prey for a passing hawk.

Likewise, Zenk noted, if an animal attacks a person, even background levels of morphine may block out enough pain to allow the person to escape. (Explore the human body.)

For now, however, this is “absolute speculation,” Zenk said. Next he plans to test the urine of people who have endured horrible pain—such as traffic-accident victims—to see if their bodies spiked morphine levels.

It’s also difficult to say whether the discovery will yield any new treatments, Zenk added. (Related: “Toxic Snail Venoms Yielding New Painkillers, Drugs.”)

But it’s possible that scientists could someday induce a person’s body to create a natural jolt of morphine that might prove less damaging than injecting the substance into the body. Morphine shots can carry many side effects, he said—especially constipation.
