The endurance As with other concepts, it does not have a universal definition since the term is used and applied to describe different situations and by different disciplines.
For example, the most common and common is the meaning that is related and used very recurrently in physical activity. So, in this area, physical (aerobic) endurance is the physical capacity that allows to carry out physical work of significant intensity for a long time. Obviously this will have a lot to do with the proper functioning of vital vital organs such as the heart, lungs and circulatory system. Physical endurance capacity is almost directly related to cardiovascular health, which should be evaluated in all individuals seeking to start or enhance an exercise plan, especially after 40 years.
On the other hand, there is also the anaerobic resistance, which also implies the maintenance of a physical effort for a long time but not exceeding ten minutes and with the absence of oxygen as a consequence of the strong effort that is made. However, it is not advisable to start an activity that requires this type of resistance without first going through aerobics, in order to obtain as much air as possible. Therefore, the metabolic and physical benefits of anaerobic endurance are not in doubt, as long as they are framed in a comprehensive exercise plan in which aerobic activities also participate.
And also in line with physical exercise, we find another type of resistance, the local resistance This will be achieved through systematic repetition or by holding a movement for a long time. But of course this resistance will need constant and regular practice over time. Generally, all these forms of physical resistance are achieved by doing them regularly, as we said, in a gym and under the strict supervision of a professional who follows the evolution, marks the errors and also the limit to which each individual in particular can reach.
Likewise, another meaning of resistance also very familiar and present in our daily lives is the electric resistance. A substance is said to have electrical resistance when it opposes the flow of current. This definition encompasses direct and alternating current. Meanwhile, depending on the size of resistance that it imposes, the substance can be conductive, semiconductor and insulating. In the traditional resistance equation, the difference in potential or voltage and the intensity of current or amperage are included. The quotient of these 2 parameters defines the level of resistance in the electrical circuit, while the inverse division gives rise to another magnitude, known as conductance and of greater application in bioelectricity models. All modern technology, in one way or another, is based on the applicability of electrical resistance equations, also known by the general name of Ohm's law.
Finally, it is worth considering the social application of the concept of endurance, whose most classic definition is linked to the formation of opposition groups to a despotic government regime or the occupation of a region or a country by foreign powers. Similarly, it is called civil resistance to the refusal by society or a group of individuals to comply with rules that are considered unfair, such as an increase in taxes. At present, the unstoppable spread of social networks has motivated the concept of "digital resistance", given that (still) in a large part of the nations there are no restrictions on free expression on the Internet, which allows the consolidation and strengthening of expressions of social resistance through the network of networks.
