Purpose. The aim of this study was to derive the regression equation for predicting VO2max of athletes by the relatively new submaximal 3'Bike Test. Methods. This test was conducted on 1501 active football male players, aged 16÷35 years. A medical anamnesis was administered and then the athletes' weight was measured. Afterwards, the athletes performed the 3'Bike Test followed by the Astrand Bike Test for comparison reasons. Results. Linear regression of the data indicated that the produced regression model, as a whole, is statistically significant. In addition, the system of predictive variables was able to explain for 48% of total variability of the criterion variable VO2maxAST. According to the regression coefficients that had been derived, a regression equation that could predict VO2max was created. A significant high correlation (r = 0.688) and a non-significant paired t-test (p = 0.782) found between the measured VO2max (Astrand test) and the predicted VO2max (3'Bike Test) indicates a large similarity between the predicted and measured VO2max values. Conclusions. The 3'Bike Test was found to be a capable measurement tool of aerobic endurance, more reliable and valid than the Astrand submaximal test, as well as being shorter, more easily executed and a better predictor of VO2max.

The aim of this study was to research the relationships between set of body variables and set of cephalofacial variables, using statistical method of canonical analysis. The measurements were done on 288 adult male entities, aged 18-35 years old. Correlation analysis indicates mediocre inter-correlation among two sets of variables. Canonical analysis has enabled the extraction of two significant canonical roots for each set of variables. While left canonical roots explain 48.9% of total variance computed for the set of body variables, the right canonical roots explain 52.8% of the set of cephalofacial variables. Reduction of the measured variables in a small number of canonical roots may facilitate the work of the physical anthropologists in studying and explaining the genetic development of the bones, cartilages and soft tissues of humans, as well as their morphological construction.

The purpose of this study was to study the latent structure of the cephalofacial variables and to explain the clustering of these measurements. Eleven cephalofacial measurements were done on 561 male entities aged 18-35 years. The collected data are analysed through descriptive parameters, correlation analysis, and factorial analyses. Correlation analysis confirms three sets of variables that realise the higher correlations with each other. According to the principal component analysis of the factor analysis three latent factors have been extracted that explain 53.3% of the total variance: the neurocranial volume factor; the transversal factor of the face; and the longitudinal factor of the face. The reduction of multiple measured manifest variables in a small number of latent factors may facilitate the work of anthropologists in studying and explaining of the genetic basis of development of bones, cartilages and soft tissues of the head and their morphological construction.

The human craniofacial bones are certainly the most important part of the body, as well as the foundation for the soft tissues of the face and head. This part of the body is extremely complex structure, which has a number of important functions, such are: diet, special senses, protection, communication. The main purpose of this research was to study and explain the latent structure of the cephalofacial measurements of female subjects. On 193 female subjects aged 18-35 years, we measured 11 cephalofacial measurements. The collected data are analyzed through descriptive parameters, Correlation analysis, and Factorial analyses. According to the results of the basic parameters the measured subjects are characterized with long, large and medium height head. Correlation analysis confirms some sets of variables that realize the higher correlations with each other. According to the principal component analysis of the Factor Analysis, with the rotation method direct oblimin, and using the Keiser criterion have been extracted four latent factors that explain 66.39 % of the total variance: The cranial factor; The factor of intracranial capacity; The transversal factor of the face; The longitudinal factor of the face. The composition of the extracted factors is compatible with the anthropological explanation of the anthropologists regarding the development of these tissues of the head.

Morphometry is a non-invasive method important to assess the size, proportions, and composition of the human body. Because the prediction is an important subject in almost all life sciences, the aim of this research was to find out the cephalofacial variables that may predict the body height. Three cephalofacial variables and the body height were measured on 288 adult male subjects of the Kosovo Albanian population, aged 18–35 years old. Using the procedures of regressive analysis we found that cephalofacial variables: head height, head circumferences, face height, significantly may predict body height, and in this way we derived the specific regression equation for estimation of the body height, based on these cephalofacial variables. The predicted body height, has relatively high significant correlation (0.512) with true body height, as well as paired T-test indicates significant similarity between these two variables. © 2015, International Journal of Morphology.

The aim of this study was to define the morpho-functional variables that best predict the explosive power of the lower extremities of basketball players of Kosova. On 113 basketball players average aged 21.3 years old, 15 morpho-functional variables were measured: Stature, Body Weight, Humeral Perimeter, Chest Perimeter, Abdominal Perimeter, Thigh Perimeter, Calf Perimeter, Triceps Skinfold, Subscapular Skinfold, Abdominal Skinfold, Thigh Skinfold, Calf Skinfold, Heart Rate, VO2max.rel., and Explosive Power that was tested through Margaria-Kalamen Test. All tested basketball players are competitors in the Super League of Kosova. Linear regression of the data indicates that the system of 13 morpho-functional predictive variables explains 62.5% of total variability of the dependant variable. The variables that indicate positive influence on dependant variable - explosive power of the lower extremities are: Thigh Perimeter (b=.413), Chest Perimeter (b=.316), and Heart Rate (-2.01). According to the results of this study, one can conclude that basketball players with higher values of the volume of thighs, with balanced muscles and core stability, as well with low rate of heart frequency during resting period, will have higher explosive power of the lower extremities. So, the conditional coaches, during the training with the young basketball players, should pay more attention to develop these morphometrical variables.

The goals of this study were to find the average intracranial capacity of the living male-entities of Kosovo Albanian population, to define cephalofacial indexes and their interrelations with intracranial capacity and to explore their latent structure.Ê Eight cephalofacial variables have been measured in 571 male entities of the Kosovo Albanian population, aged 18-35 years old. Of these measurements, 6 cephalofacial indexes and intracranial capacity were calculated. According to the results of TableÊ it can be concluded that most of Albanian males from Kosovo have long, wide and average height head, as well as most of them have brachiocephalic head, low hypsicephalic, and tapeinocephalic head, with intracranial capacity 1379.2cc. Regression Analyzes show that among other cephalofacial indexes, vertical cephalic index and transversal cephalic index have higher predictive influence on size of the intracranial capacity (VCI=1.764; TCI=-1.45).The possibility of the prediction of Intracranial Capacity (ICC) based on the values of VCI and TCI argues their joint projection on the first extracted latent factor, which has been nominated as factor of the head volume. The latent structure of the cephalofacial indexes consists of three latent factors: 1) factor of the head volume; 2) facial factor; 3) cephalic factor.

Purpose. The aim of the present study was to develop a non-exercise regression model for predicting maximal oxygen uptake (VO2max) using age, body mass, and resting heart rate as predictor variables. Methods. The VO2max of 1502 active football players aged 16-35 years was measured using the Astrand Bike Test. The obtained data were analyzed by calculating basic statistical parameters and performing correlation and regression analysis. Results. The results of regression analysis indicated that all three independent variables could significantly (p = 0.000) predict the VO 2max of the studied athletes. Measured VO2max showed significant correlation (0.688) with predicted VO2max. Student's paired samples t test indicated no significant differences between measured VO2max and predicted VO2max (p = 0.782). Conclusions. The results suggest that the nonexercise variables of age, body mass, and resting heart rate, may significantly predict the endurance abilities of athletes (VO2max). © 2014 Human Movement.

Purpose. The aim of this study was to evaluate the influence of three different mouthguards on the airflow dynamics of oral breathing under increased ventilatory conditions at peak workload. Methods. Twenty volunteer male martial art athletes were subjected to cardio-respiratory examination on a treadmill. Four trials were performed, without a mouthguard and with a maxillary boil-and-bite mouthguard, bi-maxillary boil-and-bite mouthguard, and PlaySafe custom-made maxillary mouthguard. For each of the four tests, subjects performed an identical incremental test to determine VO2max and other respiratory values. Results. Collected data were analyzed using descriptive analyses and paired-samples t tests. The results indicated similarity in almost all measured variables when testing with the custom-made PlaySafe maxillary mouthguard to values recorded without a mouthguard, while tests performed with the maxillary and bi-maxillary boil-and-bite mouthguards showed greater differences. Conclusions. The custom-made PlaySafe maxillary and maxillary boil-and-bite mouthguards do not significantly reduce airflow dynamics of oral breathing when compared with the bi-maxillary boil-and-bite, instead, these two types of mouthguards were found to positively affect aerobic capacity. ©.
