They performed two graded maximal exercise tests on a treadmill, a standard ramp treadmill test (T SR, speed increments of 1 km•h-1 every 60 seconds) and a fast ramp treadmill test (T FR, speed increments of 1 km•h-1 every 30 seconds) to determine and compare the parameters at peak values and at heart rate at the deflection point (hr dP) and ventilation threshold (vt). There were no significant differences between protocols (p>0.05) for peak values of oxygen uptake (vO 2max , 4.48±0.43 and 4.44±0.45 L•min-1), weight related vO 2max (62.5±6.2 and 62.0±6.0 mL•kg-1 •min-1), pulmonary ventilation (ve max , 163.1±18.7 and 161.3±19.9 L•min-1) and heart rate (hr max , 192.3±8.5 and 194.4±8.7 bpm) (t fr and t Sr , respectively). moreover, no significant differences between t fr and t Sr where found for vt and hr dP when expressed as vO 2 and hr. however, there was a significant effect of ramp slope on running speed at vO 2max and at the anaerobic threshold (Ant) , independent of the method used (vt: 16.0±2.2 vs 14.9±2.2 km•h-1 ;hr dP : 16.5±1.9 vs 14.9±2.0 km•h-1 for t fr and t Sr respectively). linear regression analysis revealed high between-test and between-method correlations for vO 2 , hr and running speed parameters (r=0.78-0.89, p<0.01). The present study has indicated that the vt and hr dP for running (vO 2 , ventilation, and heart rate at vt/hr dP) are independent of test protocol, while there is a significant effect of ramp slope on vt and hr dP when expressed as running speed. moreover, this study demonstrates that the point of deflection from linearity of heart rate may be an accurate predictor of the anaerobic threshold in trained runners, independently of the protocol used.

Data was collected from 134 basketball matches played in the regional Goodyear League 2002/03 season. The sample of variables included 13 standard situational efficiency indicators recorded during a basketball match. The (Factorial) principle components method was employed and the number of significant factors was determined using the Guttman-Kaiser Criterion. The initial coordinate system was transformed through a non-orthogonal rotation according to the Oblimin criterion. Six inter-independent latent dimensions explaining 67.5 % of total variance were determined: basic offensive efficiency, the three-point play, errors in posting the defense and realisation from the free throw line, defensive agressivness on the player in possession of the ball and offensive agressivness of the player in possession of the ball, basic defensive efficiency and defensive/offensive back line efficiency. The obtained latent structure provided good interpretation of the continuance and functional dependence of 13 standardised indicators of player performance. However, these indicators are considered inadequate for explaining the complexity of the game. Additional player performance indicators should be included in future scientific analysis.

Anthropometric characteristics and jumping and sprint performances were analyzed for 45 soccer players (age 14-15; mean body height 175.4±6.61 cm; body weight 63.6±8.06 kg) according to their team positions (defender, midfielder, forward). Pearsons coefficient of correlation was used to determine the relationship between the power performance variables. There were no significant differences (p>0.05) in the power performance of players according to their team position. The only significant differences between players were in some of the anthropometric characteristics, such as height and weight linear relationship was determined between almost all the power performance variables. Since the players in this study were very young and their sports careers have not reached their peak performance, it is possible that their nominal team positions may change during their soccer careers.

Data was collected from 134 basketball matches played in the regional Goodyear League 2002/03 season. The sample of variables included 13 standard situational efficiency indicators recorded during a basketball match. The (Factorial) principle components method was employed and the number of significant factors was determined using the Guttman-Kaiser Criterion. The initial co-ordinate system was transformed through a non-orthogonal rotation according to the Oblimin criterion. Six inter-independent latent dimensions explaining 67.5 % of total variance were determined: basic offensive efficiency, the three-point play, errors in posting the defense and realisation from the free throw line, defensive agressivness on the player in possession of the ball and offensive agressivness of the player in possession of the ball, basic defensive efficiency and defensive/offensive back line efficiency.The obtained latent structure provided good interpretation of the continuance and functional dependence of 13 standardised indicators of player performance.

Body fat percentage, body mass index and somatotype were also calculated. Canonical discriminative analysis showed significant difference between the athletes of various running events, in the measures of body volume and body fat, while no significant difference was found in the variables of longitudinal and transversal dimensions of the skeleton. ANOVA and Student t-test for independent samples showed statistically significantly higher thigh and lower leg circumference in sprinters, as well as greater upper arm skinfold in middle-distance runners. The mesomorphic component is a dominant characteristic of somatotype of the runners in all events, whereas the ectomorphic component is the least marked.

A set of 21 anthropometric measures was carried out on 12 wing attack players, 6 pivots, 6 goalkeepers and 13 back court players. Body fat percentage and BMI were also calculated. ANOVA showed statistically significant differences in variables of longitudinal skeletal dimensions, body volume and body fat. Post hoc analysis showed the most statistically significant differences in aforementioned variables between goalkeepers and wing attack players. Wing attack players are found to be with the lowest height and weight values, whereas goalkeepers are the tallest and the heaviest among all players according to their game position. Differences between wing attack players and back court players have been found in variables of longitudinal skeletal dimensions, thigh skinfold measures and upper leg and upper arm circumference, latter being the only variable of difference between wing attackers and pivot players. female player, handball, morphological characteristics, playing position

Trained 400m (14 male and 14 female) track athletes volunteered to take part in this study. All subjects performed an incremental treadmill test (1 km/h speed increase per minute, 1.5% gradient). The parameters FVC and FEV1S in the male athletes were of higher values than in the female athletes, while there were no significant differences in FEV1S%. A statistically significant difference was found in the parameters for the assessment of aerobic energy capacity in favour of male athletes. Significantly higher values of anaerobic capacity were found in male sprinters (5.7 km/h) compared to female sprinters (4.5 km/h). In other physiological parameters such as HRmax values and HR at VT there were no statistically significant differences. It can be concluded that it is necessary to determine whether there are differences in these parameters between male and female sprinters which will result in a more organized plan for the collective training process. Studies like this can help coaches develop athletes' performance according to their abilities.

The maximal oxygen uptake achieved was 63,2 ± 5,4 ml/kg/min, with maximal running speed (Vmax) of 18,4 ± 1,7 km/h; maximal heart rate (HRmax) was 188,1 ±1 bpm. The selected functional variables at the ventilatory anaerobic threshold (VT) were: VO2max/kg=50 ± 6 ml/kg/min, % VO2max/kg 79 ± 4 %, speed of running 13,5 ± 2.0 km/h, % Vmax 79 ± 4%. The functional profile of Croatian, in comparison with world-class1,2,3,5, triathletes showed lower values for all parameters. As in other endurance sports, these parameters for evaluation of the aerobic capacity are not the sole predictors of racing success. Although other factors are also important, these parameters play a decisive role for success in triathlon and in the selection of talent for the sport.

On the basis of results received, level of glicolitical abilities has been analysed along with the analysis of the difference in the level of footballers training. By standard procedures of descriptive statistic, the anthropometric measurements have been dealt with (height, mass and estimated body fat level) along with testing parameters on the 300 yards (result, maximum heart frequency and maximum lactate concentration) in both testing. Analysis of differences in two clubs in the two measurements has been performed by using the Student t-test for dependent and independent samples. On the basis of results received, it can be concluded that the better result in the 300 yards test along with higher levels of maximal lactate, points to the higher level of training, which is one of the basic conditions for achieving quality competing results in football.

Forty-eight (48) athletes and 24 tennis players from Croatian national leagues were compared in morphological and physiological parameters of an all-out incremental treadmill test with gas exchange measurements. Tennis players' HR max (192.96±7.75 bpm) shows values that are most different to 400-meters sprinters (200.13±6.95 bpm). Maximum running speed of tennis players on the treadmill (v max) is no different with the speed achieved by sprinters, while there are significant differences among other athletes. Values in running speed at anaerobic threshold (v AnT) show no statistically significant difference with the values for athlete sprinters and 400-m sprinters. Values of RvO 2 max for tennis players indicate significant similarities with athlete sprinters and 400-m sprinters while the values of RvO 2 AnT are nearly identical with the values for sprinters and show no statistically significant differences (p<0.05). The results indicate that values achieved by tennis players approximate most different those of the middle and long distance runners. This singles out the possible importance of the anaerobic capacity and the high level of sprint endurance in tennis players. Knowing these characteristics is the basis for planning and implementing training systems that will enable the increase and optimal usage of energy capacities of tennis players in possibly improving sports results.

Data were analysed and compared between the different national level male running groups.The LD group had lower HR max 187.1 ± 7.4 and S4 group had highest HR max 200.6± 6.8 as well as HRR and %HRR max. The HR recovery was fastes in LD runners, while 400m runners had the slowest heart rate recovery. These results suggest that athletes competing in running events with predominantly aerobic metabolic demands are likely to have lower HRmax nad faster HRR after a grade exercise tredmill test than runners competing in events with predominantly anaerobic metabolic demands.
