The exercise was carried out to evaluate and classify the level of physical fitness as an indicator of health, to measure the aerobic capacity, which in turn indicates the level of physical fitness. To achieve the objective, The most well-known test in the history of physical education is the Cooper running test, which is a maximum and field test, suitable for all age groups, teenagers, women and men, consists of running for 12 minutes, which refers to enduranceaerobics, which is the ability to tolerate fatigue caused by exercise, managing to maintain the pace and intensity for a long time without a considerable drop in physical performance. The sample consisted of 44 2nd year students, in the 1st academic semester of 2022 at the Escola Superior de Ciências do Desporto (ESCIDE) of the Eduardo Mondlane University (UEM). The main measure for assessing aerobic capacity is maximum oxygen consumption (VO2max=distance-504.1/44.9), which indicates the maximum and integrated capacity of the organism to extract, transport and use oxygen molecules as an energy substrate. The evaluation was carried out on an athletics track with a 400 meter loop. Once the Cooper test was completed, the individual results obtained in the evaluation were compared and using the average health indicator Table 1 of maximum VO2 for running, Table 2 women and Table 3 men, whose classification range is between very poor, poor, sufficient, good, excellent and higher education, resulted in an assessment of the students' physical fitness level as 1 poor, 6 sufficient, 11 good, 12 excellent and 14 superior.

Resistance is the ability to tolerate or endure something. A person's ability to perform a low or medium intensity effort over a prolonged period of time. This capacity depends on oxygen management, that is, on the balance that the subject manages to achieve between the need for oxygen for activities and the actual consumption. A person with good aerobic endurance can tolerate the fatigue caused by exercise, managing to maintain the pace and intensity for a considerable time. Through aerobic exercise, a process occurs that increases cardiac efficiency and this, in turn, improves oxygen transport and the capacity of skeletal muscles, reducing blood pressure and heart rate and, finally, causing the absorption of oxygen. oxygen has an increase in its capacity. Aerobic capacity can be defined as the maximum capacity to absorb, use and transport oxygen during physical exercise, as the longer the exercise or physical activity, the greater the need for oxygen to provide the body with greater aerobic resistance.¹

For Medeiros, (2010) cardiorespiratory fitness or aerobic resistance refers to the efficiency of the lungs, arteries, capillaries and heart, acting uninterruptedly in transporting sufficient oxygen and nutrients towards the muscles involved in the activity. Factors that influence aerobic capacity, such as genetics and heredity, have a direct relationship with the individual's aerobic potential, but the habit of regularly practicing physical exercise can reduce the incidence of these factors, being in guided practice the most effective intervention method. aerobic exercise is common. According to Kenneth Cooper² aerobic training improves the capacity of the central circulation and consequently the supply of oxygen, it also improves the use of oxygen by active muscles, reduces the appearance of cardiovascular diseases, strengthens the immune system and is efficient in the weight loss process, maintaining and increasing general physical fitness, physiological adaptations make the individual more able to perform physical activities and combatstress routine, consequently improving quality of life. Throughout the day, a person generally depends on the aerobic system for 98%.OMuscles and the cardiovascular system can adapt to increase their ability to use oxygen. Maximum oxygen consumption (VO2max) is widely used as the best measure of individual cardiorespiratory fitness, and consequently the best measure of physical fitness. VO2max is defined as the maximum volume of oxygen per unit of time (ml/min/kg) that an individual uses at maximum effort. Anyone can increase maximum oxygen consumption (VO2max), but baseline levels vary according to age, sex, health, weight and physical activity (Lia Kubelka Back,Florianópolis). Throughout the literature review, it became clear that cardiovascular training requires at least 30 minutes of exercise per session, 3 times a week, for approximately 8 to 12 weeks to ensure an increase in aerobic capacity. According to  Kenneth H Cooper² resistance is the best life insurance.

The study is quantitative in nature, descriptive, comparative and exploratory. It is based on the Cooper Test as it is a field test that is easy to administer to a large number of people simultaneously, it is suitable for all age groups, for women and men, it consists of covering the greatest distance running over 12 timed minutes, after the time has elapsed. The distance covered in meters is counted and the Cooper test protocol is used to measure VO2 max. which corresponds to the formula VO2max=Distance-504.1/44.9, these last two variants being fixed. This protocol is designed to estimate maximum oxygen consumption, which corresponds to milliliters of oxygen consumed per kilogram of body weight (ml/min/kg), the main indicator of health and/or performance. To calculate running speed, the formula was useddistance/12 min= meters/minute.

Procedure

44 students participated in the assessment, of which 8 women and 36 men aged between 19 and 39 years old. There were no exclusion criteria as participation in the assessment is mandatory except in the case of illness or injury. In accordance with the objective of measuring the level of physical fitness of students in the 2nd Year 2022 class at ESCIDE-UEM in classes related to the Discipline Sports Practices II (Athletics) of the Degree in Sports Sciences. For evaluation, a previous record of age and weight was recorded, the Cooper Running Test and its protocol were used, on a 400 meter track and the results illustrated in Table 1 were obtained, all members of the class see columns referring to age, weight and race Cooper test, taking as a reference average indicator of VO2 Max for the race, Table 2, 3 the VO2 Max results were obtained, the average speed of the race was calculated using the formula Distance/12 min= Speed ​​and finally a comparison was made between the student who covered the same distance but have different weight, represented in Table 4–6. The illustrated evaluation results arestarting age, weight, distance in meters, estimated VO2max, average speed and the corresponding evaluation of each sample unit.

After carrying out the exercise that resulted in the tables above, it was expected that, based on the results of the Cooper running test, women would present physical fitness capabilities similar to those of men, as mentioned in the bibliography that women can with stand prolonged efforts so well because their metabolism is processed more economically. Students with the same distance covered, which has greater weightuses a greater maximum volume of oxygen per unit of time (ml/min/kg), which suggests that it has better aerobic capacity level, comparative Table 6.  The result of the Cooper 12-minute running test (maximum test) helps to understand aerobic endurance capacity through maximum oxygen consumption (VO2max) and reflects the person's health status (physical fitness), which corroborates reports that are included in the bibliography review.^3–12

Of the 44 students who make up the sample, following the Cooper protocol for running, differentiated into women and men and grouped by age, they present the following levels of physical fitness: Poor 1=2.27% man; Sufficient 6=13.63% with 1 woman and 5 men; Good 11=25% being 2 women and 9 men; Excellent 12=27.27% being 4 women and 8 men and Superior 14=31.81% being 1 woman and 13 men. The VO2max values ​​presented are generally above the Good capacity by 84.08%. As for performance it can be seen that the student who has more body weight compared to the other with the same distance traveled uses a greater maximum volume of oxygen per unit of time (ml/min/kg), which leads to the consideration that comparatively he has a better Physical aptitude.
