Abstract:
Background and Study Aim. To investigate how bilateral pedaling asymmetries change at exercises with different levels of intensity. Material and Methods. Eight students of cycling, average age 25.4 years, were investigated. In the experiment, we recorded the pedal force of the right and left legs during three consecutive exercises of different intensity 35%, 55% and 85% respectively. To quantify the difference in physical parameters of pedaling between the left and right legs, we used two approaches that complement each other in the analysis of bilateral asymmetry. One approach involved determining an asymmetry index, and other was statistical analysis. Results. The Student's t-test indicated that the difference between the power samples for the left and right pedals decreased at 85% exercise intensity vs. 55% with a statistical significance of α = 0.05. The bilateral asymmetry in most cases decreased or in two cases remained unchanged. The cases where there was no statistically significant difference between the power samples for both legs at 85% and 55% intensity levels had the lowest asymmetry index. Conclusions. The bilateral pedaling asymmetry is reduced at 85% exercise intensity compared to the 55% one. The reduction in asymmetry index ranges from 1% to 14.1%, Combining the asymmetry index and the Student's t-test can increase the informativeness of pedaling power data when analyzing bilateral asymmetry.

Abstract:
Background and Study Aim: One of the most widely applied methods to assess upper-body strength in children and adolescents is the handgrip strength test. While in adolescents it has been determined which elbow position, and which type of dynamometer are most appropriate for achieving the maximal grip strength, in children is still not clear. Therefore, the purpose of this study was to investigate whether elbow position and the type of dynamometer affect the handgrip strength in children. Material and Methods: Grip strength was measured by TKK and DynX dynamometers, and their validity and reliability were also analysed. A total of 60 children, 6 to 11 years old, participated in this study, and performed the handgrip strength test with their elbow extended and flexed at 90°. Results: While using the TKK dynamometer, grip strength was significantly higher when the test was performed with elbow extended, in contrast to those obtained with elbow flexed (14.58±3.04 kg vs 12.97±2.99 kg, p

Abstract:
Purpose: The aim of this study was to compare the coinciding anticipation timing (CAT), reaction time and dynamic balance performances of American football players according to their playing positions. Material: Thirty-five American football players, who train at least 3 days a week, and compete in Universities Protected Football 1st League, participated in this study, voluntarily. The players were divided into two playing positions: offensive (17 players, mean age: 20.76 ± 1.30 years) and defensive (18 players, mean age: 21.94 ± 2.87 years). The CAT at different stimulus speeds (6 mph, 12 mph), reaction time (visual, auditory, mixed), and dynamic balance performance (anterior-posterior, medial-lateral, perimeter lenght) were measured in the laboratory environment. The CAT, reaction time, and dynamic balance performance of players were determined by Bassin Anticipation Timer, Newtest 1000, and Technobody Prokin-200, respectively. Results: The data obtained were analyzed in SPSS (20.0) program. Firstly, the raw data for CAT performance (6mph, 12 mph) were converted to absolute error score. According to Shapiro-Wilk test result, the all data showed normal distribution. Independent Sample t test was used to determine the differences between the two playing positions. In addition, the effect size between the two playing positions was calculated in parameters with showing significant differences, and Cohen’s d (1988) values were taken into account. Compared with the defensive players (20.15±3.81 ms), the absolute error scores at fast stimulus speeds (12 mph) of offensive players (17.45±3.48 ms) was found to be significantly lower (t(33) =-2.181, p=.036). The visual reaction time of offensive players (318.11± 17.47 ms) was significantly shorter than defensive players (340.58± 32.60 ms, t(26322) =-2.560, p=.017). In terms of dynamic balance parameters such as perimeter lenght, anterior-posterior, and medial-lateral, there was no statistically significant difference between the playing positions (p>0.05). Conclusions: Perceptual-cognitive characteristics such as CAT, and reaction time performance differ according to the playing positions, and this difference may be related to the physical, and cognitive demands required by their playing positions.

Abstract:
Background and Study Aim. The objective of this study is to examine the effect of exercise on the blood levels of homocysteine, hemoglobin and hematocrit in middle-aged sedentary individuals. Material and Methods. A total of 24 middle-aged (35-55 years) sedentary individuals (12 females and 12 males) living in Batman province voluntarily participated in this study. Body weight, body mass index, Homocysteine, Hemoglobin and Hematocrit blood levels were measured before and after a walking exercise scheduled for 6 weeks. Walking exercise was administered 4 days a week for the 6 weeks. Initially, the walking exercises started as 40 min and increased to 60 min towards the end of the program. In the exercises, walking tempo was kept higher than normal and in parallel to the overall health levels of the subjects. The data obtained were then analyzed through the SPSS 25.00 package program. Results. It was determined that there were statistically significant differences in the pretest and posttest parameters of body weight, body mass index, and Homocysteine values. Additionally, it was determined that, after the 6-week exercise program applied to the female and male participants, there were statistically significant differences between the pretest and posttest parameters of body weight, body mass index, hematocrit, hemoglobin, and homocysteine blood levels. Conclusions. As the conclusion, it was determined that, after the 6-week exercise program applied to a total of 24 participants (12 females and 12 males), there were statistically significant changes in the values of body weight, body mass index, hematocrit, hemoglobin, and homocysteine blood levels. It is suggested for further studies to apply nutrition programs and exercise protocols on young people regularly doing exercise and active athletes in different branches in order to contribute to sports science.

Abstract:
Background and Study Aim. Aerobic training is effective manner of exercising aimed at improving cardio-respiratory fitness of young people. However, its effects to the elderly population (over the age of 60), depending on characteristics of the participant (gender, health status, lifestyle, etc.), is still unclear. Aim of this research is systematic overview of the available literature dealing with the topic of effects of aerobic training to cardio-respiratory fitness of the elderly population over the age of 60, depending of gender (male/female), BMI (overweight/normal weight), lifestyle (active/sedentary), health status (diabetes/hypertension/metabolic syndrome). Material and methods: Total number of papers with published research results which met the criteria was 32. Walking is effective manner of exercising which influences improvement of maximum oxygen consumption (mean value: ±SD:12.91±7.40%). Introduction of activities with greater impact (bicycle and jogging) provides more effect to the cardio-respiratory fitness (mean value: ±SD:14.28±7.48%). Results: Aerobic training intensity level (moderate vs. high) makes no significant difference to the adaptive response of the cardio-respiratory fitness in elderly population. Training in duration of 6 weeks may significantly influence increase in maximum oxygen consumption, but longer training duration, however, has better effect. Endurance training has similar effects to improvement of cardio-respiratory fitness in both men and women. On the other hand, it seems that active people have lower adaptive response in comparison to sedentary people (8.3% vs. 18.84%). Effect is similar between overweight and normal weight participants (18.48% vs. 8.6%). Positive influence of aerobic training was also observed in participants with hypertension, metabolic system and diabetes type 2. Conclusion: Results clearly suggest benefits of aerobic training on cardio-respiratory fitness of elderly population. The effect may, however, vary depending of duration, type of activity, as well as characteristics of the sample.

Abstract:
Background and Study Aim: The main purpose behind the study was to establish the challenges in relation to the acquisition of life skills among university student-athletes of Khyber Pakhtunkhwa. The study assessed the extent to which the concern existing resources, facilitators, and trainer attitude influences life skills acquisition among student-athletes. Material and Methods: Descriptive survey research design was followed to obtain desirable results. The target population of this study consisted of all those who participated in different sport at the university level of Khyber Pakhtunkhwa (KP), Pakistan. Amongst them, we selected a representative sample (n=389 fifty 50% of the total population) with the help of a simple random sampling technique. The Statistical Package for Social Sciences (SPSS) version, 24 was used to code and analyse the data. The hypotheses were tested by applying statistical tests like Step-wise regression and independents sample t-test. The significance level of 0.05 was fixed to accept or reject the set hypotheses. Results: Findings of the study indicated that existing resources, facilitators, and trainer/coach attitude significantly influences life skills acquisition among student-athletes (.001, .001 & .000 < .05). The analysed data revealed no significantly difference regarding extent to which specific challenges such as existing resources, facilitators, and trainer attitude influences the acquisition of life skills (.500, .133 & .149 > .05). Conclusions: The findings of the study revealed that all participants have agreed upon the importance of life skills. Therefore, the life skills course might be considered as an integral part of every educational curriculum of Pakistan. It is suggested that a minimum of 2 hours per week may be included in the educational curriculum of each discipline.
