Aim. The basketball referee is the person who judges all phases of the game, taking decisions in fractions of a second. For this we need to analyze him in depth meaning also his antropometric and physiological indices.

Methods. I have verified a number of anthropometric indices such as size, weight and span, a number of physiological indices: respiratory frequency, cardiac frequency, vital capacity.

Results. All correlations that can be extracted from existing tests have been objectively observed..

Conclusions. Also, the tests that are required at this date, without a centralized and well-prepared training basis, are not relevant and can not be correlated with the subjects' anthropometric or physiological parameters.

Keywords: anthropometric, physiological, basketball, referees


The referee is "the person who is in charge of conducting a sports competition." (DEXI, 2007, p.117)

"Each referee knows that basketball is a fast and exciting game with coaches and spectators, who, especially at the end of the game, can not control themselves. It is up to a good referee to prepare for such situations and to control such emotions" (Priebst, 2007, p.11)

He often applies training close to the level at which top athletes apply, the best-rated teams, with all the specialists they need.

The theoretical basis of this approach is provided by some research that states "linear increase in oxygen consumption and heart rate depending on the intensity of the submaximal effort, allows predicting by extrapolation the maximum oxygen consumption that subject might have, without the need to subject it to maximal effort." (Weineck, 1997, p.89-95)

"Physical training includes a whole system of measures ensuring a functional capacity high body by the high level of development of motor skills base and the specific optimal values of the indices morpho-functional full possession of exercises used and perfect health." (Negrea, Musat, 2016, p. 585-589)


The subjects of the research are 55 basketball referees, referees from the National Championship (Men's National Basketball League and Women's National Basketball League). I have verified a number of anthropometric indices such as size, weight and span, a number of physiological indices: respiratory frequency, cardiac frequency, vital capacity.

"Achieving high-performance in major competitions, highlighted a number of aspects that characterize the current basketball game practiced by the best teams in the world" (Predescu, Ghrtescu, 2001, p 7-9)

Below we will present the data from our substantive records on a number of 55 subjects. The data are anthropometric and physiological indices that are recorded at the beginning of each season, both on the basis of the measurements and on the basis of a medical certificate from the specialist.

Following the chart with the size index representations, we observe a high homogeneity of the subjects. And the statistical coefficient analysis table shows a coefficient of variability of 2%, so the average is representative, the median being 182cm, with a maximum of 192cm, and a minimum of 170cm.

2. Chart Weight

As a result of calculating the coefficient of variability, 10% for the weight index, we have a high homogeneity of the subjects of the proposed sample, but not as high as it is for the index height. The minimum of this index is 63kg and the maximum of 99kg.

Based on the graph for the span data of the subjects, a coefficient of variability of 3% can be observed, which means that the homogeneity is high and the average of the subjects is representative.

Following the correlation of anthropometric data we have the following results:

As we can well see, the data of the anthropometric indices currently used for the evaluation of the basketball referees are correlated with each other, and we can say that they are very important for the level of training and performance of the referees.

Next, we will present the statistical data and the resulting graphical data for the physiological indices of the sample of subjects for preliminary testing.

Having a 7% coefficient of variability for the physiological index, the heart rate HR, we can conclude that the homogeneity in this echelon is high, the mean being representative.

As it can be noticed from the table above, we have a coefficient of variation of 5%, for respiratory rate, RR which means a high degree of homogeneity and a relevant average of the sample.

The coefficient of variability of the vital capacity, VC, index is 3%, which means a relevant mean of the sample and a high homogeneity.

We will further present the correlations between the physiological indices of the sample:


I would like to say that the work of a referee to become the best is similar to the work of a top player. He must also have an important amount of talent, and by talent here we mean having a "sense of game", which is indispensable for a referee who wants to reach the highest levels.

"The modern basketball game is running at high speed, at a sustained pace, which implies great physical effort". (Negrea, 2016)

"On the background of a specific and partial endurance effort that runs close to the aerobic-anaerobic threshold, the basketball referee performs short and medium speed efforts." (Martinescu, 2014)

We have to notice that, over the years, the changes to the regulation have led to an increase in the importance and responsibility of referees during the games. We must not forget that the referee is that judge in the field who has the power and responsibility to make decisions.

"The considerable increase in the role of the specific training of the referees involved in the development of the number of the international sports competitions and, implicitly, of the national ones, specialized the training co-entrant and methodology according to the needs of the competitions." (Predescu, Ghitescu, 2001, p. 128).

"In order to obtain good performance by a referee, the ability to solve the specific problems that arise during the competition must be developed by creating similar situations in the training." (Arnauld, 2004, p. 34)

Observing all this new challenges and trends in basketball we can say that this topic is not enough researched in our country, although at the present time the bases of a very rigorous training system for basketball referees in Europe are laid.


In conclusion, after analyzing the preliminary data, we note that between the indices that are currently demanded, namely the anthropometric, size, weight, span and physiological indices, FC, FR, CV, for which we need medical certificates from specialized doctors, inconclusive data result on the level and objective evaluation of basketball referees. Also, the tests that are required at this date, without a centralized and well-prepared training basis, are not relevant and cannot be correlated with the subjects' anthropometric or physiological parameters.

All correlations that can be extracted from existing tests have been objectively observed. Thus, we can underline the fact that at this time the tests applied to the basketball referees are very little relevant with the level of umpire age, the development of the training and the performance of the referees for higher level results.

"When a referee realizes that he is responsible for seeing all players on the court, refuses to be intimidated by players, couaches and supporters and leads the game with the full flexibility of his judgement, and implements knowledge with skill and courage, only then can he be considered worthy by the name of the referee." (FRB., 1995)


For all of our participants from my study I want to say thank you.
