Physical fitness is the ability to cardiorespiratory system function effectively throughout your workday, perform your usual other activities and still have enough energy left over to handle stress or emergencies that may arise in the course.
Components of physical fitness are:
* Cardiorespiratory (CR) endurance - the efficiency with which the body delivers oxygen and nutrients needed for muscular activity cardiorespiratory system and transports waste products from the cells.
* Muscular strength - the greatest amount of force a muscle or muscle group can exert in a single effort.
-Muscular endurance - the ability of a cardiorespiratory system muscle or muscle group to perform repeated with a sub-maximal force for extended periods of time movements.
-Flexibility - the ability to move the joints or group of joints through an entire, normal range of motion.
-Body composition - the percentage of body cardiorespiratory system fat you have in relation to their total body mass.
Improving the first three elements of the above condition will have a positive impact on body composition and will result in less fat. Excessive body fat away from the other fitness components, reduces performance, affect the appearance, and negatively affects your health.
Factors such as speed, agility, muscle strength, hand-eye coordination and eye-foot coordination are classified as components of the condition "engine". Cardiorespiratory system the most affect his athletic ability factors. Appropriate training can improve these factors within the limits of their potential. A sensible weight loss and fitness program seeks to improve or maintain all the components of physical fitness cardiorespiratory system and motor through sound, progressive and specific physical training mission.
Principles of exercise
Adherence to certain basic principles of exercise is important for developing an effective program. The same principles of exercise apply to everyone at all fitness levels, from the Olympic-caliber athlete to the weekend jogger, these basic principles of exercise must be followed.
Regularity
To obtain a training effect, you must exercise often. Must have each of the first four components of fitness at least three times a cardiorespiratory system week. Exercise can often do more harm than good. Consistency is also important in resting, sleeping, cardiorespiratory system and following a proper diet.
Progression
The intensity (strength) and / or cardiorespiratory system duration (how long) of exercise must gradually increase to improve the level of fitness.
Balance
To be effective, a program should include activities that address all aspects of fitness, since overemphasize one of them can hurt others.
Variety
Provide a variety of activities reduces boredom and increases motivation and progress, training must be geared toward specific goals. For example, people become better runners if their training emphasizes running. Although swimming is great exercise, cardiorespiratory system it does not improve after two kilometer long as a program is running.
Recovery
A day of training for cardiorespiratory system a given component of fitness should be followed by a training day easier or more days off for components and / or muscle group (s) to help permit recovery. Another way to allow recovery is to alternate the muscle groups exercised every other day, cardiorespiratory system especially when training for strength and / or muscular endurance.
Overloading
The work load of each exercise session must exceed the normal demands placed on the body to get a training effect.
