The total athletes selected for this study were (N=30) fourteen male and fourteen female with age range of 18-24. The athletes were oriented about the test and its objective, There was no control group in this study. An experimental group used for intervention after grouped for three. The athletes were assigned randomly for three groups having different week of stretching introduction during warm up but same training. Every group will have the intervention of no stretching, static and dynamic stretching weeks for three times interchangeably. The intervention lasts for nine weeks. After the intervention from one stretching type to the others the tests were taken at the fifth day of every week. One-way repeated measures ANOVA were conducted to compare scores on all tests across groups while repeated measure of ANOVA was employed to check the performance difference of the athletes while having different stretching week. Based up on the test there is a significant difference in athletes, agility, Broad Jump and 400m performance during dynamic stretching than static and No stretching. Better Activeness were reported during Dynamic Stretching-3 (DS-3) mean=4.46±.33, static stretching-3 (SS-3) mean=4.23±.42, and No Stretching-3 (NS-3) mean=3.54±.88. 7. In addition to this Better Pace Performance test result shows that DS-3 mean=4.55±.32, SS-3 mean=4.34±.56, and NS-3 mean=4.34±.27. Furthermore the Consistency of Performance test result shows that DS-3 mean= 4.63±.42, SS-3mean=4.63 ±.42, and NS-3 mean=4.42 ± .28. , There was a significant effect for Activeness/Direct Enrollment scores During Dynamic stretching time training. Activeness average score which is close to very good and followed by static stretching which is close to good. There is also a significant decline for Activeness/Direct Enrollment on athletes during no stretching time which is less than good. On the other hand there was no significant effect for Better Pace/Consistency and Consistency of Performance but average score mean of dynamic stretching has shown better result than static stretching and no stretching. From the data collected it is concluded that the dynamic stretching has a better effect on agility broad jump and, 400m performance followed by static and No stretching. A significant better accomplishment of Activeness during dynamic stretching was recorded followed by static and No stretching .Thus it is concluded that overall dynamic stretching can support for better performance than static and no-stretching performance.</em></p>Sintayehu Kasahun Kiminad Amensisa Kebede Legesse (Ph.D)

https://ejss-esa.edu.et/index.php/ejss/article/view/44
<p><em>This quasi-experimental study aimed to investigate and compare the effects of an 8-week plyometric training program and a circuit training program on selected physiological and physical fitness variables in U-17 male football trainees from the Ethiopian Sport Academy. The study involved 22 participants, who were randomly assigned to either the plyometric training group or the circuit training group. Measurements of speed, power, agility, resting heart rate, and respiratory rate were taken before and after the training programs. Statistical analysis was conducted using SPSS ver.20 and paired t-tests, with a significance level of 0.05. The results showed that the plyometric training group significantly improved in power (p=0.00, p<0.05), speed (p=0.00, p<0.05), and agility (p=0.00, p<0.05). The circuit training group significantly improved in speed (p=0.00, p<0.05), resting heart rate (p=0.00, p<0.05), and respiratory rate (p=0.00, p<0.05). Resting heart rate and respiratory rate did not show significant differences in the plyometric training group (p>0.05). Similarly, power and agility did not significantly improve in the circuit training group (p>0.05). Based on these findings, it can be concluded that an 8-week circuit training program has positive effects on speed, resting heart rate, and respiratory rate, while plyometric training has positive effects on speed, power, and agility. Accordingly, it is recommended that a combined session of circuit and plyometric training may lead to significant improvements in physiological and physical fitness variables in male football trainees.</em></p>Emebet Fikre

https://ejss-esa.edu.et/index.php/ejss/article/view/56
<p><em>The purpose of this study was to investigate the differential impacts of indoor and outdoor exercise environments on the physiological and psychological responses of Rori Hotel gym clients in Hawassa, with a focus on mood, motivation, perceived exertion, and exercise program adherence. The research employs a comparative analysis methodology, utilizing both quantitative measures and qualitative assessments. Participants engaged in exercise sessions both indoors and outdoors, with physiological parameters such as heart rate, blood pressure, and oxygen saturation being monitored. Additionally, self-reported measures including mood, motivation levels, perceived exertion, and adherence to exercise programs were recorded through standardized questionnaires and interviews. Preliminary findings suggest that exercising in outdoor environments elicits a significantly more positive effect on mood and motivation compared to indoor exercise. Moreover, participants reported lower perceived exertion levels during outdoor sessions, indicating a potentially greater enjoyment of the activity. Physiological responses, while varied, indicate a trend towards increased oxygen saturation and lower heart rates during outdoor exercise. These results have important implications for designing exercise programs tailored to the preferences and needs of Rori Hotel gym clients in Hawassa. By incorporating outdoor exercise opportunities, hotel management can potentially enhance client satisfaction, motivation, and adherence to fitness routines. Further research is recommended to explore long-term effects and specific demographic influences on these findings.</em></p>Abera Dessalegn
