A vast amount of research has been performed illustrating that the execution of certain conditioning activities at maximal or near-maximal intensities can acutely enhance subsequent athletic performance with given sufficient recovery. This phenomenon is known as post-activation potentiation (PAP) and its use within the field of strength and conditioning has grown rapidly as performance enhancing effects have been demonstrated within athletic movements such as jumping and sprinting. Objective: The purpose of this study is to analyse the effectiveness of PAP training on sprint performance and power production among Malaysian female hockey player. Methods: A total of 18 well-trained athletes (age 25 ± 3.7; mass 54 ± 4.9; height 160.8 ± 2.8; relative strength half-squat 1.9 ± 0.3; relative strength hex-bar deadlift 1.7 ± 0.5; relative strength hang clean 0.8 ± 0.1) were tested for 20 meter sprint time and counter-movement jump (CMJ) test during the preparation phase. This study used two different groups such as experimental group (EG) and control group (CG) and each player were randomly assigned. Both groups were completed training in twice per week for a period of eight week training program. The EG performed a total of 16 session by having 2 different training blocks. Each block has a period practice of training for 4 weeks and each block also has different types of exercise. Meanwhile, CG completed 16 session based on coach training program and did not practice at the same time with the EG. The study intervention program including pre-test and post-test activities were conducted before and after the study. Result: A data analysis of paired t-test and independent t-test was used and the level of significance in all statistical analyses was set at p ≤ 0.05. The result showed that 8-weeks of EG displayed significantly improved in sprint performance (p ≤ 0.005) and power production (p ≤ 0.005). Moreover, result also revealed a significant difference between EG and CG in sprint performance (p ≤ 0.000) and power production (p ≤ 0.008). Conclusion: In short, the result emphasized the contribution of kinetic and kinematic parameters for sprint and power performance. The EG result seem significant for athletic performance. Therefore, this findings is of great practical interest for coaches and fitness trainers and relevant to female hockey players and consequently maybe used in training program.

Background and objective:    Drug abuse is one of the diseases that are highly dependent on individual behaviors and social interactions. This disease can be created in places like military garrisons due to their relationship with such behaviors. Therefore, soldiers and staffs are at risk of drug abuse. The aim of this study was to determine the effect of prevention training program of drug abuse on reducing risk factors in soldiers and staffs in Iran.Methods:In this quasi-experimental interventional study, 392 soldiers and staffs in two military garrisons in Khorasan Razavi (Intervention group 242 and control group 150) were randomly conducted to training program. The data collection tools were questionnaire of identifying people in risk of addiction, life skills questionnaire and demographic variables. The questionnaires were completed as self-report. Educational content was consisted of seven training sessions (60-minute) that only applied in the intervention group. 45 days after the last training session, educational software was distributed as a reminder in the intervention group. The two groups were followed up three months after the intervention. Finally, the data were analyzed using SPSS version 16.Results:  The findings showed that there was no significant difference between the two groups in demographic variables (Pvalue>0.05). The mean scores for risk factors on drug abuse after training program (Depression and feeling of inability, Positive attitude toward drug abuse and Anxiety and fearing of others) were significantly improved in the intervention group (Pvalue<0.05). Also, life skills variables except the problem solving skill (Pvalue>0.05) had a significant change after intervention in the intervention group (Pvalue<0.05).Conclusion:The findings indicated that the prevention training program of drug abuse based on life skills training could reduce the risk factors of drug abuse for soldiers and staffs in military garrisons.

AbstractThe goal of this study was to assess the effects of a supervised slackline training program in a group of soccer players. Thirty-four male division I under-19 players (16.64 ± 0.81 years) agreed to participate in the study. They were randomly divided into an experimental group (EG) and a control group (CG). The first group (EG) followed a 6-week supervised slackline training program (3 sessions/week; 5-9 min/session), while the CG performed only regular soccer training. Several variables were assessed in all participants: acceleration (20-m sprint test), agility (90º turns test), jump performance (squat jump, countermovement jump), and postural control (Center of Pressure ( CoP) testing: length, area, speed, Xmean, Ymean, Xspeed, Yspeed, Xdeviation, Ydeviation). Ratings of perceived exertion and local muscle ratings of perceived exertions were also recorded after each slackline training session. At post-tests, there was a significant increase only in the EG in acceleration, agility, squat jump and countermovement jump performance, as well as several CoP variables: area in the bipedal support on a firm surface, and length, area and speed in the left leg on a firm surface. The program was rated as “somewhat hard” by the players, while quadriceps, gastrocnemius and tibialis anterior were the most exerted muscles while slacklining. In conclusion, slackline training can be an effective training tool for young, high-level soccer players.

Purpose: To examine the effect of a 10-week plyometric training (PT) on the kinematic and kinetic properties of prepubescent girls during squat jump, countermovement jump, and drop jumps. Methods: Twenty-four untrained girls (aged 9–11 y) were assigned to a training group (TG) and a control group. The TG followed twice a week PT for 10 weeks. Squat jump, countermovement jump, and drop jumps performed from heights of 20, 35, and 50 cm were tested before and after PT. Jump height, kinematic, and kinetic parameters were evaluated using a motion analysis system and a force plate. Results: Jumping height in all jump types increased significantly after PT for the TG (P < .001). After training, the TG presented increased power (P < .001) and knee angular velocity (P < .001), higher knee flexion at the deepest point during the braking phase (P < .001), longer contact time (P < .001), and unchanged stiffness and reaction strength index (P > .05). No differences were observed in the control group (P > .05). Conclusion: These findings indicate that a 10-week PT positively affected jumping performance in prepubescent girls who improved their drop jump performance after training not by adopting a stiff/bouncing jumping style of short contact time and increased stiffness, but a compliant/absorbing style of prolonged contact time.

Purpose: To analyze the effects of a 9-week plyometric training program on the sprint times (5, 10, 20, and 30 m), change-of-direction speed (modified T test and modified Illinois test), jumping (squat jump, countermovement jump, countermovement jump with arms, and horizontal 5-jump test), upper-body strength (right and left handgrip, back extensor strength, and medicine ball throw), and balance (Y and stork balance tests) of female handball players. Methods: Athletes were randomly divided into experimental (n = 21; age = 13.5 [0.3] y) and control (n = 20; age = 13.3 [0.3] y) groups. Training exercises and matches were performed together, but the experimental group replaced a part of their normal regimen by biweekly upper- and lower-limb plyometric training. Results: Both groups improved performance, but to a greater extent in the experimental group compared with controls for 20- and 30-m sprint times (Δ% = 9.6, P < .05, d = 0.557 and Δ% = 20.9, P < .001, d = 1.07, respectively), change of direction (T test: P < .01, Δ% = 14.5, d = 0.993 and Illinois test: P < .01, Δ% = 7.9, d = 0.769), vertical and horizontal jumping (P < .05), all measures of upper-limb strength (P < .001), and left-leg stork balance (P < .001, Δ% = 49.9, d = 1.07). Conclusions: A plyometric training program allows female junior handball players to improve important components of their physical performance.

Background/Objectives: This study examined the effects of introducing programming as a technological tool for teachers’ Technological Pedagogical Content Knowledge (TPACK) development.Methods/Statistical Analysis: Thirty-two teachers were divided into two groups, completing different types of TPACK educational programs. The control group’s TPACK training program was based on information and communication technology (ICT), while that of the experimental group was based on programming. To verify the effectiveness of the TPACK training program, tests were administered before and after the educational program. A statistical analysis of questionnaire results also investigated changes resulting from TPACK.Findings: Both the control and experimental groups showed statistically significant improvements in the post-test compared with the pre-test. However, in the detailed areas of TPACK by group, the improvements in the two groups differed. Unlike the control group, the experimental group showed a statistically significant improvement in the knowledge related to technology. This result illustrated that programming is effective in solving the problem of integrating technology into the classroom. In contrast, there was no significant difference in the post-test, as this was applied in the short term. However, programming has been shown to affect Technological Pedagogical Knowledge (TPK), Technological Content Knowledge (TCK), and TPACK. In summary, the results showed that a TPACK educational program based on programming is effective for teachers’ TPACK development. Keywords: TPACK, In-service teacher, Programming, TPACK-P, Educational program

The purpose of study was to resolve the effect of plyometric training and repeated sprint training on physical performance. The study was conducted on 41 subjects in two experimental groups (plyometric/repeated sprints training). Before and after the training program, subjects were subjected to diagnostic procedures that included standard test protocols. Results proved a statistically significant difference only after the plyometric training program compared to the repeated sprint group in countermovement jump (8.65% vs. 2.21%). In variable repeated jumps, an increased value was recorded (2.9% vs. 4.29%), like in sprint variables after the training program where certain trends of progress happened after the repeated sprint ability training and the specificity of the program (5 m = 0.89%, 10 m = 1.07% and 25 m = 1.35%), while plyometric training recorded unchanged values at 5 and 10 m, and a 0.27% improvement at 25 m. Stagnation of the 20-yard test was recorded in both groups. There was no difference between training programs in any variables of functional capacities, with similar measures recorded in repeated sprint ability. After six weeks of both training types, positive changes can be expected in explosive strength of lower extremities, increases in acceleration area, and maximum speed.

The aim of this study is to investigate the effects of the core training program applied for 8 weeks to basketball players aged 16-18 on free throw and vertical jump performance. 22 male basketball players (11 experimental group, 11 control group) aged 16-18 participated in the study voluntarily. While core training was applied to the basketball players in the experimental group, 2 days a week for 8 weeks, together with the basketball training, the basketball players in the control group only continued their routine basketball training. Free throw and vertical jump performance tests were applied to the subjects before applying the 8-week core training program (pre-test) and after the 8-week core training (post-test). Statistically significant difference was found between pretest and posttest in terms of experimental group free throw test values (p<0.05) Statistically significant difference was found between the pretest and posttest values of the control group in terms of free throw test values (p<0.05). When the experimental group and control group free throw pretest and posttest were compared, no statistical significance was found (p>0.05). A statistically significant difference was found between the pretest and posttest in terms of vertical jump test values of the experimental group and the control group (p<0.05). However, the development in the experimental group was higher than in the control group. There was no statistically significant difference between the free throw test difference mean values of the experimental group and the control group (p>0.05). A statistically significant difference was found between the vertical jump test difference mean values of the experimental group and the control group (p<0.05). As a result, it can be said that 8-week core training has positive effects on the development of vertical jump performance on basketball players, but no effect on free throw performance. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0870/a.php" alt="Hit counter" /></p>

The Impact

The aim of this research was to examine the impact of pelvic girdle stability training in children with hypotonic cerebral palsy on functional sitting control. Thirty children with hypotonic cerebral palsy in both sexes, with their ages ranging from two to four years were used in the study. There were fifteen children in the experimental group and fifteen children in the control group. The study group received pelvic girdle stability training program in addition to a selected program for upper limbs and trunk muscles strengthening exercises, while the control group received only the selected program for upper limbs and trunk muscles strengthening exercises. Results revealed significant difference of GMFM88 (sitting domain) (P < 0.01), stationary raw scores and stationary standard scores of PDMS-2 (P < 0.05) but no significant difference of age equivalent of PDMS-2 (P > 0.05). GMFM88, on the other hand, had a significant difference (sitting domain) (P < 0.05) but no significant difference of stationary raw scores, stationary standard scores and age equivalent of PDMS-2 (P > 0.05) in the control group. Paired t-test were conducted for comparison between pre and post treatment mean values of sitting domain and stationary scores in each group. From the obtained results of the present study, we conclude that pelvic girdle stability training program was more effective in generating core muscle activity for functional sitting control compared to traditional physical therapy of upper limbs and trunk muscles strengthening exercises in children with hypotonic cerebral palsy. Keywords: Pelvic girdle stability, functional sitting control, hypotonic cerebral palsy.

ABSTRACT Introduction: Plyometric training significantly improves strength performance, including in aquatic sports. Objective: To compare changes in thigh girth, hamstring flexibility, squat jump height, and 200m swimming trial time induced by plyometric training in recreationally-trained swimmers. Methods: Eighteen recreationally-trained male swimmers (age=18-20 years) were randomly divided into a plyometric training group (PTG) and a control group (CG). All the swimmers completed a six-week speed swimming training plan. In the PTG only, the last ~15 min of each session was replaced with plyometric exercises. The physical characteristics and the thigh girth were measured before and after the six weeks of training. In addition, sit-and-reach flexibility and squat jump tests were conducted, as well as a 200m swimming trial. Results: Two-way ANOVA with post-hoc analysis revealed an increase in sit-and-reach flexibility (PRE: 4.5±5.3 cm; POST: 10.9±5.9 cm, p<0.01) and squat jump height (PRE: 24.9±3.7 cm; POST: 28.3±4.2 cm, p<0.01) and a decrease in 200m-swimming time (PRE: 220±26.5 sec; POST: 204±24.4 sec, p<0.01) for the PTG only. Comparing the absolute changes (post-pre) between the groups by the Student's t-test, the PTG showed a greater increase in distance reached in the sit-and-reach flexibility (PTG: 6.34±0.6 cm vs. CG: 2.4±1.2 cm, p<0.01) and squat jump height (PTG: 3.4±0.7 cm vs. CG: 0.7±0.3 cm, p<0.01) than the CG. In addition, the 200m swimming time decreased significantly more than in the CG (PTG: -15.1±2.4 sec vs. CG: -0.8±2.7 sec, p<0.01). Conclusion: Plyometric training improves jump height, flexibility, and 200m swimming performance in recreationally-trained adult swimmers. Level of Evidence II; Lesser quality RCT.
