Studies have revealed that this type of physical fitness training is more efficient in burning calories over a shorter period than steady-state activity or performing the exercise routine repeatedly. Another benefit of this training is that it enables an individual to develop his or her routine by mixing and matching his or her choice of activities or exercises. Different mixes and matches can produce different results.
There are different categories or types of physical fitness training. Each corresponds to a defined purpose or fitness goal such as the development and improvement of one or more of the five dimensions of physical fitness, or for participation in a particular type of sports and rehabilitation through physical training, among others. Note that the different types of training also correspond to the different categories or types of exercises.
Endurance is your ability to perform physical activity over time. You might be able to serve aces and hit winning forehands and backhands, but if your muscles cramp or you run out of energy after a few games, you won’t win any matches. You build endurance by exercising for longer periods without stopping, working at a slower speed than when you interval train. This type of exercise is usually aerobic, calling on your slow-twitch muscle fibers and burning more fat than glycogen, depending on the speed you work. The slower you work, the higher percentage of your calories burned comes from fat.
Strength, cardiovascular endurance, balance, agility and flexibility should be the goals of any well-rounded fitness program. But how do you go about developing these skills? The key is variety. Don't spend all your time in the weight room or on the treadmill. Include different types of fitness training in your routine and you'll see better overall results in your exercise performance and how your body performs and feels in daily life.
Developing research has demonstrated that many of the benefits of exercise are mediated through the role of skeletal muscle as an endocrine organ. That is, contracting muscles release multiple substances known as myokines, which promote the growth of new tissue, tissue repair, and various anti-inflammatory functions, which in turn reduce the risk of developing various inflammatory diseases.
Before the industrial revolution, fitness was defined as the capacity to carry out the day’s activities without undue fatigue. However, with automation and changes in lifestyles physical fitness is now considered a measure of the body's ability to function efficiently and effectively in work and leisure activities, to be healthy, to resist hypokinetic diseases, and to meet emergency situations.
