It is necessary to clarify concepts to better understand the possibilities of movement of human beings today.
Sports: running out on a competitive basis, in general, involves physical activity. The exception is Chess. The sport, regardless of the level of competition: Elite, Federated, School, Communal, Leagues, or recreational, involves a confrontation, and hence, an effort risky for adults and children in competitive training.
Physical activity: Any activity that involves movement, indifferent of the degree of effort, regularity, type and intent. It includes the activities of daily living.
Fitness: physical activity planned, deliberate, knowledge-based physiological and driving with an established planning, which contains the short, medium and long term.
About this clarification, and typical of the confusion, many people recommend the sport to sedentary adults, in columns of prestigious newspapers. Others, often ask: What is the most comprehensive sports?
The answer is that physical exercise should be scheduled to meet all the needs of the subject, in relation to the development of motor skills and physical qualities:
Resistance Aerobics .- General Linked to the development of central systems involved in the improvement of oxygen consumption (cardiovascular system, endocrine, nervous and others)
Aerobics .- Specific Resistance Linked to muscle capacity to oxidize nutrients (capillarity muscle, levels of myoglobin, mitochondrial space, oxidative enzymes)
general Anaerobic Resistance .- Linked to the thickening of the walls of the heart, through a work of high pulsations, which influences the development of central systems.
Specific Anaerobic Resistance — Linked to muscle capacity to generate energy from glycolysis, lactification.
Maximum Force .-, endurance, speed.
Speed .- reaction, segmental.
Flexibility .- Mobility articulate (ligaments) Muscular elongation.
It is true that to serve in Sports, we must develop each of these physical qualities to varying degrees depending on the sport or the role that is fulfilled in a particular sport but to sedentary adults who want to improve their status, if only for summer season, it is advisable to do physical exercise overseen by an expert on the subject, physical exercise for health and quality of life.
