The DISADVANTAGE with constant resistant devices is the inconsistent matching of resistive forces and muscular forces that occur during an exercise movement. You don ' 't have to work just as hard during every phase of the movement (for example the top position in the squats or biceps bar curl). There ' 's an "easy" phase in the movement which makes the exercise a little less effective than it could have been (using free weights instead).
Also, resistance training with FREE WEIGHTS is more difficult and not without risk for beginners, older people or people with injuries. They might not have the stabilizer strenght in their core muscles to do all the exercises safely. In this case, EXERCISE MACHINES are easier and more safe to use - at least in the beginning ot a training regimen.

This will in turn stress the muscle fibrers to the maximum. Also, the speed is controlled by the exercise machine through the whole range of the movement and that is an advantage for the general population because it takes away the ballistic movement of the exercise and therefore eliminates the danger of overextended joints or risks of pulled muscles.
The DISADVANTAGE is the same as for all other machines: it does not have the natural feel as using free weghts. Also, the controlled speed add to the innatural feeling. For athletes in sports training (who ' 's sports movements are usually ballistic) this technology may have a limited usefulness. For bodybuilding, the technology can be useful for changing things up once in awhile and to chock the muscles through a plateu by overloading the muscles (since the devices puts such a high level of stress to the muscles).
STATIC RESISTANCE DEVICES
This is a type of training where you contract the muscles but no movement

There are 8 levels of resistance that this bike provides. The magnetic tension allows you to find the proper tension to maximize their workout. It’s the ideal way for anyone who gets bored riding the same bike over and over again. You’ll be able to get into shape in no time with this
Muscle endurance is the ability to perform a lot of repetitions against a given resistance for a long period of time. The combination of strength and endurance results in muscle endurance. Muscle endurance is used in may sports such as rowing, swimming, cycling, distance running, field hockey and American football. Normally, an endurance muscle program involves lifting about 12-25 repetitions of moderate loads. In some cases, this is inadequate for many sports such as boxing, canoeing and x-cross skiing.
I have been doing resistance training since past four years and it has always been a bodybuilding type training i.e. training for muscle mass. Stretching exercises both before and after resistance training has been an important factor in improving my flexibility and increasing my joints’ range of motion. When you can flex, extend or circumduct your joints through full range of motion without any pain that is called flexibility. Many individuals often overemphasize flexibility training and not focus on improving the strength of the surrounding muscles which can lead to an injury. I have always ensured that I warm-up properly before any type of stretching. I always do an active warm-up like 10 minutes treadmill walk/elliptical/arc trainer, etc. As research has proved and I have also experienced that static stretching can temporarily lower the strength levels, I do dynamic stretching before beginning my resistance training. Dynamic stretching helps improve strength, flexibility and endurance, speed, neuromuscular activation and coordination. It is especially important if you use higher repetitions, sets and/or heavier weights.
Exercise is the key to a happy and healthy life. Exercise helps maintain or obtain a healthy body weight. It’s also a great way to bond with fellow gym attendees. For all you know, your soul mate could be running on the treadmill next to you. Studies show people who exercise are happier overall. Exercise is important in day-to-day life.
Controlled increases in physical stress through progressive resistive exercise cause muscle fibers to hypertrophy and become capable of generating greater force.3 Early emphasis is on restoring joint range of motion and muscle flexibility, however, resistive exercises are not delayed. The initial emphasis of muscle loading should be on endurance, accomplished with lower loads and higher repetitions. Progressive resistive exercises are initiated at the available range and progressed to new positions as wrist range of motion returns in all planes. Both the overload principle and the SAID Principle (Specific Adaptation to Imposed Demands) are important considerations in therapeutic exercise dosing.1,3,11 Within pain tolerance, dosing progressive resistive exercises that maintain a therapeutic stress level will encourage muscle tissue hypertrophy. Finding activities that produce the correct force and repetition, without injury, is the goal of the remobilization period. Starting with low force, moderate to high repetitions, and encouraging therapeutic rest following induced stress is important to both the overload principle and the SAID Principle. Additionally, it is important to prevent dosing resistive exercises that exceed optimal stress, which may result in injury. The patient’s response to therapeutic exercise should be assessed during, immediately following,
The truth is, they do produce side effects and irregular muscle growth. By banning the use of performance enhancing drugs, just like steroids, sports competition will have a much healthier and fairer environment to participate in. Performance Enhancing Drugs in Sports The use of steroids and performance-enhancing drugs is a common trend that is currently fascinating athletes all over the world. Athletes who are using these drugs are damaging the sport and harming their bodies at the same time.
Performance enhancers are bad for your health and they might help when your at a sport but when older, it can cause illness.
Powerlifting can take its toll on the body. In powerlifting, the athlete trains for maximum strength meaning that the weight used is very heavy and often for very low repetitions, ranging anywhere from 1-5; usually 80% and over of a one rep maximum for most of the work done. This can take its toll on joints/lower back; lots of preventative measures are utilized to prevent joint pain such as: using aids like knee/elbow sleeves, knee/wrist wraps, and weightlifting belts. Injuries are quite common thus most powerlifters will take preventative measures, or pre-rehabilitation, to prevent them.
This is important for beginners, so that the can reduce the risk of injury when moving on to strength training.
To provide exercise professionals with an overview of resistance training benefits, safety issues, and programming guidelines for patients who have been diagnosed with osteoporosis or at risk of getting it.
Exercise can benefit an individual in many ways. Through research I have found several articles which have been written throughout the years that address these benefits. Some of these benefits are to prevent diseases, to improve stamina, to strengthen and tone, to enhance flexibility, to control weight, and to improve quality of life. All of these benefits will be address throughout this paper. However, even though exercise does benefits an individual, it does also depends on their circumstances. For example, exercise can be done to help with a pregnancy and after a pregnancy, to control diabetes, and to help the brain function for achievement in school.
Other training methods include the use of resisted sprints. These resisted sprints will use equipment such a towing sled, resistance parachutes or weighted vests. The use of this equipment can increase the resistance and help produce increased stress on the muscle and a training effect while not affecting the kinematics of the performers sprint (Duthie, 2006).
reason, it is a physically demanding exercise that it will require good stamina in order to finish
