Exercise is physical activity that enhances or maintains fitness and overall health. It is performed for various reasons, including weight loss or maintenance, to aid growth and improve strength, develop muscles and the cardiovascular system, hone athletic skills, improve health, or simply for enjoyment. Many individuals choose to exercise outdoors where they can congregate in groups, socialize, and improve well-being as well as mental health.
Pneumatics is a branch of engineering that makes use of gas or pressurized air.
An actuator is a component of a machine that produces force, torque, or displacement, usually in a controlled way, when an electrical, pneumatic or hydraulic input is supplied to it in a system. An actuator converts such an input signal into the required form of mechanical energy. It is a type of transducer. In simple terms, it is a "mover".
Physical fitness is a state of health and well-being and, more specifically, the ability to perform aspects of sports, occupations, and daily activities. Physical fitness is generally achieved through proper nutrition, moderate-vigorous physical exercise, and sufficient rest along with a formal recovery plan.
A stationary bicycle is a device used as exercise equipment for indoor cycling. It includes a saddle, pedals, and some form of handlebars arranged as on a (stationary) bicycle.
The leg press is a compound weight training exercise in which the individual pushes a weight or resistance away from them using their legs. The term leg press machine refers to the apparatus used to perform this exercise. The leg press can be used to evaluate an athlete's overall lower body strength. It can help to build squat strength. If performed correctly, the inclined leg press can help build knees that can handle heavier free weights, on the other hand, it also carries a risk of serious damage since locked knees can bend the wrong direction throughout the exercise.
A cable machine is an item of equipment used in weight training or functional training. It consists of a rectangular, vertically oriented steel frame about 3 metres wide and 2 metres high, with a weight stack attached via a cable and pulley system to one or more handles. The cables that connect the handles to the weight stacks run through adjustable pulleys that can be fixed at any height. This allows a variety of exercises to be performed on the apparatus. One end of the cable is attached to a perforated steel bar that runs down the centre of the weight stack. To select the desired amount of resistance, move the metal pin into the labelled hole in the weight stack. The other end of the cable forms a loop, which allows the user to attach the appropriate handle for the exercise. Most cable machines have a minimum of 20 pounds of resistance in order to counterbalance the weight of the typical attachment.
Strength training, also known as weight training or resistance training, involves the performance of physical exercises that are designed to improve strength and endurance. It is often associated with the lifting of weights. It can also incorporate a variety of training techniques such as bodyweight exercises, isometrics, and plyometrics.
Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a common example. In this type of machine, hydraulic fluid is pumped to various hydraulic motors and hydraulic cylinders throughout the machine and becomes pressurized according to the resistance present. The fluid is controlled directly or automatically by control valves and distributed through hoses, tubes, or pipes.
A load cell converts a force such as tension, compression, pressure, or torque into a signal that can be measured and standardized. It is a force transducer. As the force applied to the load cell increases, the signal changes proportionally. The most common types of load cells are pneumatic, hydraulic, and strain gauge types for industrial applications. Typical non-electronic bathroom scales are a widespread example of a mechanical displacement indicator where the applied weight (force) is indicated by measuring the deflection of springs supporting the load platform, technically a "load cell".
Exercise equipment is any apparatus or device used during physical activity to enhance the strength or conditioning effects of that exercise by providing either fixed or adjustable amounts of resistance, or to otherwise enhance the experience or outcome of an exercise routine.
An exercise machine is any machine used for physical exercise. These range from simple spring-like devices to computerized electromechanical devices to recirculating-stream swimming pools. Most exercise machines incorporate an ergometer. An ergometer is an apparatus for measuring the work a person exerts while exercising as used in training or cardiac stress tests or other medical tests.
A weight machine is an exercise machine used for weight training that uses gravity as the primary source of resistance and a combination of simple machines to convey that resistance to the person using the machine. Each of the simple machines changes the mechanical advantage of the overall machine relative to the weight.
The pull-down exercise is a strength training exercise designed to develop the latissimus dorsi muscle. It performs the functions of downward rotation and depression of the scapulae combined with adduction and extension of the shoulder joint.
A jack is a mechanical lifting device used to apply great forces or lift heavy loads. A mechanical jack employs a screw thread for lifting heavy equipment. A hydraulic jack uses hydraulic power. The most common form is a car jack, floor jack or garage jack, which lifts vehicles so that maintenance can be performed. Jacks are usually rated for a maximum lifting capacity. Industrial jacks can be rated for many tons of load.
Functional training is a classification of exercise which involves training the body for the activities performed in daily life.
Hydraulic exercise equipment is a form of strength training equipment based on fluid dynamics to provide motion resistance by use of hydraulic cylinders. They can be used in a number of strength training programs, and are most often found in circuit training gyms.
The following outline is provided as an overview of and topical guide to exercise:
Bodyweight exercises are strength training exercises that use an individual's own weight to provide resistance against gravity. Bodyweight exercises can enhance a range of biomotor abilities including strength, power, endurance, speed, flexibility, coordination and balance. Such strength training has become more popular among recreational and professional athletes. Bodyweight training uses simple abilities like pushing, pulling, squatting, bending, twisting and balancing. Movements such as the push-up, the pull-up, and the sit-up are among the most common bodyweight exercises.
When treating a person with a spinal cord injury, repairing the damage created by injury is the ultimate goal. By using a variety of treatments, greater improvements are achieved, and, therefore, treatment should not be limited to one method. Furthermore, increasing activity will increase his/her chances of recovery.
