ABSTRACT The main objective of this study is to determine the correlation between aerobic capacity and physical work in athletes involved in athletics.
In Sports Medicine, indicators of aerobic capacity and physical work influence the way sports, both are determined through laboratory equipment and instruments that allow us to know these variables by the direct method.
The field clinic provides information in an indirect way, allowing the significant changes seen in the athlete, to increase these indicators through consistent and systematic training.
was performed a treadmill test and a laboratory at veloergómetro to 9 athletes of both sexes (5 males and 4 females), including within high performance, events and middle distance background and the results compared with of themselves ern to a test field, which is to run 12 minutes without any external stimulus to mediate.
The results were: the values \u200b\u200b(both sexes) of PWC170/Kg VO2/Kg product and workloads on the treadmill and veloergómetro, are positively correlated (r = 0.71 and 0, 80) with the results of these variables to make the Cooper test to determine aerobic capacity and integrated into Formula Karpman calculations for determining physical work capacity.
Integrating Test-Karpman Cooper has a high degree of application and use in obtaining operational parameters.

SUMMARY
The main objective of this study is to know the correlation of de aerobic capacities and the physical work in athletes who practice athleties.
In the Sport Medicine, the indicator of aerobic and physical work capacities have certain influence in the sport way both have being determine by mens of equipments and laboratory instruments. The give us the opportunity to know this variables by means of a direct method.
The ground clinic give us and indirect way of information. It permits us to appreciate significants changes in the athlete with the indicators growing or by means of a sistematic training.
The test were made in the lab on a treadmill and on a cycle-ergometer to nine athletes of both sexes, five males and four females within the high perfomance in the long distance and half long distance events, and the results were compared with those of themselves when they realized the test on the ground that consisted on running during 12 minutes without any external stimulus.
The results that have been found are: the values of the VO2 /Kg and those of the PWC170/Kg (in both sexes), as a result of the workload on the treadmill and a cycle-ergometer wich are positively correlated (r = 0,71 and 0,80) with the results obtained on these variables when they realized the Cooper´s Test to determine the aerobic capacity and to integrate the Karpman´s formula in the calculations in order to determine the physical work capacity.
The integration of Cooper-Karpman Tests has a high grade of utilization and application in the obtainment of the functional parameter.
Key Word: Athleties, Maximal Oxygen Output, Physical Work Capacity related to the body weight (VO 2 / kg and PWC170/Kg)
Introduction to 9 were studied athletic training athletes and the results obtained in the laboratory and the field is were compared with themselves.
The main objective of this study is to compare both tests to determine their correlation, and the degree of significance in athletes involved in athletics.
The findings of VO2 max and PWC170 and their values \u200b\u200brelative to body weight (VO2/Kg and PWC170/Kg) in applying the test batteries in different conditions (laboratory and field) in both sexes, the correlation (r = 0.71 and 0.80) and no significant differences between these variables. We provide the information directly and indirectly, that allows us to appreciate the possibilities that the athlete has to absorb the constant workload on its way to the way sports. MATERIAL AND METHOD
9 athletes were studied, belonging to the National Athletics Centre in Santiago de Cuba, at the beginning of his general training. Of these, five males, three of them middle-distance train and two background; and four female middle-distance train. The athletes were subjected to physical load on a treadmill with gas analyzer Erich Jaeger firm, which had the following features: applied loads of 2 minutes each, with varied slope on the mat, with speeds increasing from 8 to 24 km / h.
Every 30 seconds were recorded VO2 max values \u200b\u200bof heart rate (fc) and VO2/Kg
The scheme was applied loads up to the exhaustion of the athlete. Distance was calculated, taking into account the speed of each of the applied loads. Later
athletes underwent exercise testing in the mechanical meter mark veloergó Monark, where sub-maximal loads applied. The powers of the charges were calculated using the nomogram used in our center (1) to determine the PWC170 (Tables I and II).
This determination is based on applying two workloads (N1 and N2) with a duration of 5 minutes each and with a rest period between two to three minutes.
Karpman and colleagues. (2) recommend choosing the powers (N1 and N2) so that fc.1 achieve 100 to 120 and fc.2 of 140 to 170 contractions per minute. For use stethoscope heart rate, measuring the same at rest and within 15 seconds of each of the charges; through fc. 1 obtained, we calculate N2 where: PWC170 = N1 + (N2-N1) 170 -f1/f2-f2 and knowing the athlete's body weight to calculate the PWC170/Kg each.
In medical management training, are important laboratory tests in the same magnitude must be assessed in the field clinic.
In order to correlate these laboratory tests on the ground, after a week that were recovered from the laboratory tests, apply to the 9 athletes in question, the Cooper test, which consisted of a race for 12 minutes, without any external stimulus to mediate with a view to obtaining a specific brand for that time and complete it, using the stethoscope take fc in a time of 10 seconds, multiplying by 6, thus knowing the same to the minute calculated the distance traveled. Using
Cooper's formula for the VO2/Kg Max (Max VO2/Kg = Speed \u200b\u200b[Mts x min] x 0.2 + 3.5) (3) got the Max VO2/Kg indirect, then multiplying this by the body weight we find the VO2 Max athlete
PWC170 to get the starting point was the formula Karpman and clearing the same for the calculation of elite athletes, we have: VO2 max = PWC170 x 2.2 + 1070; clearing the same then: PWC170 = Max VO2 - 1070 / 2,2 substituting the value of VO2 max, obtained by each athlete in the formula set forth above was determined PWC170 and the PWC170/Kg. The statistical analysis was conducted by the Department of Computing IMD (Institute of Sports Medicine), using a mini computer that was determined LTEL/20 central tendency parameter arithmetic mean (x) and dispersion: the standard deviation (SD).
was determined using the Student test for paired samples, if there are significant differences between the studied parameters.
statistical analysis was performed to find the Pearson correlation coefficient. RESULTS
The values \u200b\u200bof VO2 max and PWC170, and their respective values \u200b\u200brelative to body weight in men, in applying the battery of tests in different conditions (laboratory and field) are shown in Table III. Linear correlation between indicators VO2 Max, Max VO2/Kg, PWC170, and Max PWC170/Kg VO2/fc, but not with the fc, distance traveled and time spent in the race. As
significant differences between the values \u200b\u200bobtained in the fc distance traveled and time spent in the race (p 0.05) in oxygen pulse indicators, fc., Distance traveled and time spent (Table IV) DISCUSSION
In Table III, whose values \u200b\u200bcorrespond to the athletes, the VO2 max, VO2 max / kg, PWC170, PWC170 / kg and VO2 max / fc product of workloads in the conveyor belt, are positively correlated (r = 0, 91 to 0.71 - 0.91 - 0.80 and 0.90) with the results obtained in these variables to make the Cooper test (3) to determine aerobic capacity and integrated into the formula calculations Karpman (2) for determining the physical work capacity . No significant differences in the indicators mentioned above and if the heart rate, distance traveled and time spent in the race (p 0.05).
is very likely that the arithmetic mean of fc (185 ppm) reported in the "clinic on the ground" made on the court, exceeds that found in the laboratory (160 ppm), for work in less time -12 minutes - these athletes traveled 294 meters more than that calculated on the mat stock in the laboratory, which infers a greater effort, we should also add the speed of the headwind and the irregularity of the track (curves), which logically act negatively in the performance of the activity. Hi
VO2/Kg These values \u200b\u200bare very consistent with those reported (4, 5, 6), for athletes whose quality is fundamental to develop overall strength.
Table IV shows the results obtained by female athletes, appreciating linear correlation variables VO2 max, VO2 max / kg, PWC170, PWC170/Kg (r = 0.91 - 0.71 to 0.91 - 0, 80) respectively, in the statistical analysis of laboratory tests and clinical in the field.
in this group is significant difference (p 0.05) VO2 max indicators / fc, fc, trip distance and time spent.
In the field test the arithmetic mean of the fc was 180 ppm. We can infer that this is because the athletes on the field at one time ran 260 meters lower than those in laboratory. Adding accidents listed when making the analysis in males.
These results are consistent with those reported by (4.6). At the clinic on the ground, the two groups, male and female athletes were used to fund the race done, this is shown by the distance traveled since the field was higher than in performed in the laboratory and in less time, plus increased heart rate (Tables III and IV). We note that two of these athletes was the second time in his career played on the treadmill and the rest first.
Our results confirm once again that even without sophisticated means, we can obtain data that are closer to the reality of the state of assimilation of workloads by athletes, just have the clinic on the ground with batteries that will truly foster desired goal; taking in our favor being implemented on the means of training and competition. At no point denying development acquiring science and technology with the application of highly developed equipment to dig into the changes that originate in the human body to cope with stress tests, for which we are unprepared, without a previous exercise routine.
