The study aims to identify the progression of progressive speed training basis on the duration of training of the Santali tribe and Bengali high school boys. Subjects were Santali tribe and Bengali adolescent schoolboys and their ages ranged between 13 to 15 years selected from Bankura District of West Bengal, India. These two groups were further divided into control and experimental groups and in each of the groups, there were 20 students. Initially, 4 weeks of uniform conditioning training was given to all groups before the pretest T1 was conducted. Further, consecutively 3 more post-tests (T2, T3, & T4) were conducted after every 4 weeks providing progressive speed training. In the descriptive part Mean trimming was revealed. For the comparison of performed Tests timing, MANOVA, ANOVA, and LSD post hock test were employed. The result of the study reveals that Non-tribal (Bengali) and Tribal (Santali) adolescent schoolboys responded positively with the designed progressive speed training. This progression of sprint test timing took place progressively over time on the Bengali and Santali boys distinctly within the groups. Progression of Bengali boys took place from Test 1 to Test 2 numerically but not statistically, which is the dissimilarity in the process of progression of speed ability with the Santali boys. It is concluded that alike progressive speed training is equally effective for the Santali tribe and Bengali schoolboys but the progression of Bengali Boys begins a bit slower in the early stages than the Santali tribe in the sprint ability.

The balanced reaction of both sides of the human helps in achieving the highest movement output. The purpose of the study is to compare simple reaction time between university sports and sedentary female students based on preferred and non-preferred hand. Subjects were selected from Jashore University of Science and Technology, Bangladesh. They were bachelor and master students and were between 19-26 years old. There were 20 students in each group of sports and sedentary female students. Data was collected using the AVR machine. An average of 5 trials was calculated as the time score in millisecond. The result shows that in simple choice auditory reaction time of hands between sports and sedentary female students in the preferred hand, sport female mean = 18.25 ms and SD = 2.07 ms and sedentary female students' mean = 20.45 ms and SD = 1.67 ms with t (0.05) (38)=-3.695 and p = 0.001.On the other hand, in the non-preferred hand Sport female mean = 20.20 ms and SD = 1.80 ms, and Sedentary female mean = 21.70 ms and SD = 0.98 ms with t (0.05) (38) =-3.382 and p= 0.002. Moreover, in the simple choice auditory reaction time between the preferred and non-preferred hand of sports and sedentary female players' preferred hand mean = 19.35 ms and SD = 2.167 ms, and non-preferred hand mean = 20.35 ms and SD = 1.616 ms, t (0.05) (39) =-5.639 and p= 0.00. So it is concluded that University sports female students are superior to sedentary female students in simple choice auditory reaction time in both the hands. Further, University female students' preferred hand is faster in simple choice auditory reaction time than that of non-preferred hand.

CG need not lie within the physical bounds of an object. Human beings do not remain fixed in the anatomical position and the precise location of the CG changes constantly with every new position of the body and limbs. CG plays an important role in maintaining balance, equilibrium, and breaking inertia during the performance of a sports technique. Purpose of this study is to discover the pattern and make the comparison of CG height and CG velocity changes in the execution of frequently used soccer kicks within and between the kicks by the male players. Five male players played for the Bangladesh National Football teams were selected as subject and their age was between 16-19 years. A Cannon EOS7D with the capacity of 55 f/sec camera placed on sagittal plane at the backside of the kick 5.00 meters away and at 1.13 meter of height to capture kicking actions of the players on Coronal/Frontal plane. The best frame was selected out of 3 trials. 2D motion Analysis Software Kinovea 0.8.25 was employed for the quantitative analysis of the video clips. Changing of the CG height position in percentage was studied in three different phases i.e. Ground contact, Ball contact, and Follow-through in reference to erect standing CG height of the players. In addition, CG velocity changes were also studied in ball contact and follow-through phases. This study demonstrates that the male soccer players demonstrate inconsistency in CG height reduction in performing all three phases (Ground Contact, Ball Contact, & Follow-through) in all selected five kicks (Push Pass, Instep Kick, Lofted Kick, Chip Shot, and In-swerve Kick), but highest reductions have been located in the ball contact phase of all the kicks. Players change CG height in the same manner among the five selected kicks in each of the phases distinctly. Players experience CG height drop in Instep Kick differently between ball contact and ground contact phases. Players display higher mean CG velocity in ball contact phase than follow-through phase in Push Pass but remaining other kicks exhibit opposite actions. Players display CG velocity in all selected soccer kicks in the same manner at ball contact and follow-through phases. Players change CG velocity differently between Push Pass and Instep Kick, In-swerve Kick, Lofted Kick at follow-through phase.
