Circuit Training Pros and Cons Fitness Equipment

It's no secret why circuit training has been successful as a business opportunity: Works! Circuit training is a proven exercise system that, for many women, has proved more effective than diet and nutrition programs alone.

The clubs routine health training circuit is fast and simple, allowing each woman to progress at their own pace. The ladies exercise in a circle, each one in a season. Spend 30 seconds or 45 in each station, either working a hydraulic resistance machine or doing aerobics. The entire routine takes only 30 minutes.

there is enough anecdotal evidence to demonstrate that circuit training can help women achieve rapid weight loss. But what about the training in technology behind the workout? Does the equipment in this type of fitness exercise weight loss real, or just another fad?

To fully understand the fitness and exercise equipment is important to understand the four different technologies that the equipment:
1) Apparatus constant resistance
2) variable resistance devices
3) static resistance devices
4) Capable of resistance devices

Constant resistance devices:

"The constant resistance term means a weight (resistance) does not increase or decrease during the year ". (Source: International Association of Sports Sciences, 2001) The amount of resistance encountered by the user remains unchanged since the beginning of the movement year until the end.

Examples of training or weight lifting with constant resistance devices would be lifting a barbell, dumbbells, or using a weight stack cable. Weight training in this manner has some inherent disadvantages. First, the constant exercise of non-resistance weight lifting corrects changes in skeletal muscle influence a movement occurs during exercise. Second, this method does not take into account the reduction of effort that comes with fatigue.

When following a weight lifting routine with constant resistance devices, the user experiences changes in leverage for the movement of the joint. For example, curling weigh the amount of muscle force required is much greater in the bottom of the movement (when the weights are waist level) than it is at the top of the movement (when the weights are close to the chin). As the dumbbells approach the top of the movement, leverage improvement and the user does not have to work so hard.

Therefore, the user does not get the most benefit for the "easy" part of the movement. Muscles need stress to gain strength and endurance, so with relatively minor effort of constant resistance devices some of the benefits are gone.

Some experts argue that constant resistance exercise is more natural than any weight lifting program because of the imbalance of leverage matching with the actual movement of the body daily.

Variable resistance devices:

"When weighing trees by pulling a cable that goes over a pulley and attached to a weight, which is involved in the formation of a constant resistance "(source: International Sports Science Association, 2001). Some exercise equipment manufacturers have experimented with pulleys that are not round or do not have the hole in the exact center of the pulley, resulting in different levels of resistance felt during different points in the movement of exercise.

Unlike constant resistance devices, fitness equipment does not match variable resistance naturally with the human body works. Some exercise scientists view this as a disadvantage, because it can cause disorders in the brain centers that interpret patterns of force and motion.

The advantage of fitness equipment is variable resistance that amplifies the level of stress placed on muscles, forcing them to work equally hard throughout the full range of motion. Critics respond that since everyone is different is the size, height and strength is almost impossible for match with influence around the world with the leverage of the machine.

Static resistance devices:

"Contracting your muscles no movement is called static contraction. Isometric exercise was coined to describe this kind of stress "(source: International Association Sports Sciences, 2001).

The public, looking for a new point of weight loss in the 1950's and early 1960, approved the isometric exercise as their new weight lifting workout. Unfortunately, scientists eventually proved what many weight watchers had already learned: isometrically contracting muscle results in muscle only gaining strength in that position. To gain strength throughout the range of motion, the user would have to contract isometrically muscles along every imaginable angle throughout the range!

Today, few people consider using devices such as static strength part of his weight loss system for the simple reason that isometric exercise is the least effective of the four training technologies.

Devices with resilience:

"Like the variable resistance devices, with capacity for resistance to the machinery is designed to enable exert maximum resistance throughout the full range of motion in each exercise. In doing so, you are able to maximize the amount of effort from the muscles to receive "(Source: International Sports Sciences Association, 2001).

With capacity for resistance exercise equipment somewhat controls the resistance encountered, allowing the user to exert maximum force throughout the range of movement and throughout the year.

This is the type of gym equipment used in the circuit fitness centers. Again, the main benefit is that the user can exert maximum force in any position, allowing for full exercise and complete. As an example, consider dumbbell curls. Traditional dumbbell curls result of reduced leverage in the top of the movement. Training exercise equipment circuit, however, applies even and constant force throughout the range of motion. In other words, the computer circuit training places muscle in constant tension for more time than alternative training technologies.

"Tension (resistance that is stressful enough to make the muscles to adapt), together with sufficient time over which it applies, go hand in hand to produce superior gains "(source: International Association Sports Sciences, 2001).

Another advantage of hosting the resistance exercise equipment is relatively controlled speed of movement drastically reduces the possibility of injury. As ballistic movement is virtually impossible in this type of equipment, injury from overextended joints, pulled muscles and uncontrolled movements is also highly unlikely.

Conclusion:

It is easy to see that the technology behind the workout training circuit is solid. Circuit training using resistance exercise equipment capable of delivering consistent results.
