The aim of this study is to compare the physiological responses given to the tests of 100 m Circular Modified Mechanical Running (DMMK) and 20 m Go-to-Return Modified Mechanical Running (GMMK). Women’s Basketball 2 11 basketball players playing in the league (age 21.09 ±1.81 years, size 168 ±2.83 cm, VA 64.90 ±10.43 kg and VY 20.97 ±3.84%, VO2max 41.56 ±6.16 ml/kg/min) participated. In 100 m DMMK and 20 m GMMK tests, the testers run at a specific speed (8, 10, 11, 12, 13, 14 and 15 km/s) 3 minutes. DMMK is made of a 100 meters round trail, GMMK is made of a 20 meters flat trail. 1 minute interruption was given before each riding speed increased and during this time the capillaries taken from the ear breast were measured as full blood hemolysis by the electro-enzimatic method of laktate (La) in blood samples (~25ul). During the tests, oxygen consumption (VO2) and heart rate (KAH) were recorded with the Cosmed K4 b2 oxygen analyzer. The test has been completed. The running speeds in the fixed blood laktate concentrations (2, 2.5, 3, 3.5, 4 mmol/L) and the KAH and VO2 values in these speeds are obtained by graphic method. The differences between the data obtained as a result of the tests were assessed by the Wilcoxon Combined Two Examples Test in dependent groups. There was a significant difference in lactate response at running speeds of 10, 11 and 12 km/s (Z = -2.934, -2.934, 2.934; p< 0.05). A significant difference was found in the KAH answers at running speeds of 8, 10 and 11 km/s (Z = -2.192, -2.666, -2.192; p< 0.05). There were significant differences in the running speeds of 2.5, 3, 3.5 and 4 mmol/L (Z = -2.521, -2.701, -2.701, -2.2). 666; p< 0.05 There was a significant difference between the VO2 values in the concentrations of 3.5 mmol/L LA (Z = -2.312; p< 0.05). As a result, the levels of physiological difficulty created by the resistance protocols applied in the field environment at the maximum running speed are different. In the determination of the intensity of individual load in resistance training, the DMMK test may be recommended.

The purpose of study was to compare the physiological responses of modified 100 m circular (MCRT) and 20 m shuttle run tests (MSRT). Eleven 2nd division women basketball players (age 21.09 ±1.81 yrs, mass 64.90 ±10.43 kg, height 168 ±2.83 cm, body fat 20.97 ±3.84 %, VO2max 41.56 ±6.16 ml/kg/min) were participated. Participants performed incremental exercise with determined running speeds (8, 10, 11, 12, 13, 14 and 15km/h) for 3 min duration during 100 m MCRT and 20 m MSRT. Before increasing the running speed, 1 min rest intervals were given, during this resting period earlobe capillary blood samples (~25ul) were collected and subsequently analyzed for lactate (La) with electro enzymatic method as hemolysis whole blood. During the tests, oxygen consumption (VO2) and heart rate (HR) were recorded with Cosmed K4 b2 analyzer. Tests were ended when subject reached volitional exhaustion. Running speed at constant blood lactate concentrations (2, 2.5, 3, 3.5, and 4 mmol/L), and HR, and VO2 values at these speeds were determined from the groups. Wilcoxon paired analysis was use to test for differences between values. The level of statistical significance was set at (p< 0.05). It is observe that, the La responses of subject to the determined running speeds were higher at MCRT. The differences of La responses to the running speeds of 10, 11 and 12 km/h were significant among the tests (Z =-2.934,-2.934, 2.934, respectively; p< 0.05). HR responses to the running speeds were higher at MSRT compared to MCRT. HR responses to the running speeds of 8, 10 and 11 km/h were significantly different between the tests (Z = -2.192, -2.666, -2.192, respectively; p< 0.05). The running speeds of constant La concentrations at 2.5, 3, 3.5 and 4 mmol/L were significantly different, however, the running speeds of constant La concentrations at 2 mmol/L were similar (Z = -2.521, -2.701, -2.701, -2.666; respectively, p< 0.05). There significant differences were found through VO2values at 3.5 mmol/L concentration (Z = -2.312; p< 0.05). The results demonstrated that endurance protocols administered in field conditions caused different physiological strain at maximal speeds. MCRT test can be suggested to determine individual training load in endurance training
