Investigation of the Problem Solving and Excellence Levels of the Secondary School Students Who Do Sports and Does Not

In this study, it was aimed to compare the problem solving and perfectionism levels of the students who do sports and do not sports in terms of various variables, and to determine the correlation between problem solving and their perfectionism. In the province of Among the competitions between secondary schools in the 2018-2019 academic year, Milas district of Muğla province, 171 sports students between the ages of 13-15, whose sports age is at least 2 years, were randomly selected among the sports students. SPSS 22.0 statistics program was used in the analysis of the data. After the descriptive analyzes were made on the data, as the results of the Kolmogorov-Simirnov normality test performed by comparing the scores of the participants were not normal, the difference between the groups was examined by applying the Mann-Whitney test, which is one of the non-parametric tests. The "Mann-Whitney U" test was used to determine the differences between the groups. Statistical analyzes were tested at 95% confidence level, p<0.05 values were considered statistically significant. Under the "spearman's rho" test for the correlation between perfectionism and problem-solving scale. As a result, although the perfectionism and problem solving levels of the students who do and do not do sports have a meaningful result, the effect of doing sports varies according to gender; We can say that there is a positive correlation in the sub-dimensions of perfectionism and problem solving skills

Examination of Aggression Levels and Empathic Tendency Levels of Secondary School Students who Involve or not Involve in Sports

AbstractThis study was conducted to examine the aggression levels and empathic tendency levels of secondary students who involve or not involve in sports. “Aggression Inventory” developed by Kiper (1984) and “Empathic Tendency Scale” developed by Dokmen (1998) were applied to a total of 514 secondary school students (consists of 266 males, 248 females) who had been studying in a secondary school in the city center of Corum province and had been randomly selected in the academic year of 2010-2011. “Multivariate Analysis of Variance (MANOVA)” and “One-Way Analysis of Variance (ANOVA)” were used for the analysis of data and as a result of these variance analyses; “The Scheffe's Test” was used in order to determine the source of the difference. According to the findings obtained, it has been observed that the students whose family members involve in sports found to have higher destructive, assertive and overall aggression scores when compared to the students whose family members do not involve in sports. It was found that assertive aggression scores of the students who involve in sports are higher than the students who do not involve in sports. It was found that empathic tendency scores of the students who are also national athletes are higher than the scores of students who are club athletes. As a result, the empathy level of people decreases with the increasing level of aggression. It can be argued that the passive aggression decreases with the increasing empathic tendency and assertiveness increases with the increasing empathic tendency

Isokinetic Strength Profile Of Shoulder Internal And External Rotators Of Adolescent Volleyball Players

Objectives: The aim of this study was to investigate the effects of limb dominance and gender on isometric, eccentric and concentric strength of the shoulder internal and external rotator muscles in adolescent volleyball players. Methods: Forty adolescent volleyball players [Male: 23( Age: 15.5±1.4 yrs, Body weight: 72±10.2 kg, Height: 184.4±7.6 cm, BMI: 20.9±2.6 kg/m2), Female: ( Age: 16.7±0.9 yrs, Body weight: 60.7±8.2 kg, Height: 172.5±5.3 cm, BMI: 20.4±2.3 kg/m2) participated in this study. Isomed 2000 isokinetic dynamometer was used to measure muscle strength testing. Isometric strength testing of shoulder internal and external rotator muscles were performed at 90 ° shoulder abduction and external rotation position. In the same position, concentric and eccentric muscle testing was performed at 90°/s angular velocity. Strength outcomes were recorded as Nm/kg. 2-way repeated measures of ANOVA was used for statistical analysis. Results: Dominance by gender interaction was not found significant for internal rotator (IR) and external rotator (ER) muscles' strength (IR: F(1,72)=2.87, p=0.06, ER: F(1,72)=1.98, p=0.15). There was a significant strength by dominance interaction for internal rotator muscles (F(2,72)=18.52, p<0.001). Isometric strength was greater in dominant limb (p<0.001)while concentric strength was found greater in non-dominant limb(p=0.006). Eccentric strength was found similar for limbs (p=0.18). IR muscles showed greater strength during eccentric (1.03±0.05), concentric (0.76±0.03) and isometric test (0.69±0.03), respectively. On the other hand, external rotators showed greater strength during eccentric (0.49±0.4), isometric (0.40±0.3) and concentric test (0.36±0.3), respectively. There was no significant gender effect on the strength (IR: F(2,72)=0.31, p=0.73, ER: F(2,72)=0.42, p=0.66). Conclusion: The strength of shoulder internal and external rotator muscles do not differ according to gender in adolescent volleyball players. Limb dominance has an effect on the strength of internal rotator muscles while it has no effect on the strength of external rotators. Both muscle groups show greater strength during eccentric testing.PubMe

Does the Weighted Rope Jump Training Affect the Motor Skills in Adolescent Female Volleyball Players?

The aim of this study was to investigate the effect of a 12-week rope jumping and weighted rope jumping&nbsp; exercise programme on body composition and strength performance in 25 female adolescent volleyball players. Group 1 was trained on the weighted rope jumping (WRJ;(n=8)) diet as well as volleyball training, Group 2 on rope jumping (RJ;(n=9)) diet as well as volleyball training and Group 3, the control (C;(n=8)), participated only volleyball training. Percentage body fat and subsequent fat free mass by Sloan and Weir’s equation,the hand grip strength by Takei Grip -D trade mark hand dynamometer, sit-ups and push-ups for endurance and standing long jump, Sergeant Jump, and medicine ball javelin tests for lower and upper extremity muscular strength were applied before and after training. There was no difference in the body weight of the three groups although there was a considerable decrease of the body fat of WRJ and RJ groups (p&lt;0,01).WRJ group was highly increased for the mean of sit-ups,standing long jump and the values of throwing the ball to the front part with two hands (p&lt;0,01). There were significant differences in the values of push-up, right hand grip strength and the values of left hand grip strength in WRJ and C groups (p&lt;0,01).In&nbsp; this&nbsp; study&nbsp; we&nbsp; showed&nbsp; that&nbsp; the&nbsp; muscles&nbsp; in&nbsp; upper&nbsp; extremity,&nbsp; lower&nbsp; extremity&nbsp; and&nbsp; abdominal&nbsp; region of a group doing exercises for 12-week programme with weighted rope would be gained a considerable power.</p

The effects of the intake of an isotonic sports drink before orienteering competitions on skeletal muscle damage

[Purpose] The purpose of this study was to investigate the effects of the intake of an isotonic sports drink (500 ml water, 32 gr carbonhydrate, 120 mg calcium, 248 mg chloride, 230 mg sodium) the level of the skeletal muscle damage of orienteering athletes. [Subjects and Methods] The study was carried out on 21 male elite orienteering athletes. The athletes were divided into two groups by randomized double-blind selection. The experimental group (n=11) was given the isotonic sports drink, while the placebo group (n=10) was given 500 ml pure water. Blood samples were taken pre-competition, post-competition, 2 hours post-competition and 24 hours post-competition. [Results] The pre-c troponin, myoglobin and creatinine kinase serum levels of the placebo group were significantly lower than the post-competition and 2 hours post-competition values. The 24 hours post-competition levels of the same analyses were also significantly lower than the post-c and 2 hours post-competition. The pre-competition troponin, myoglobin and creatinine kinase levels of the experimental group were found to be significantly lower than the post-competition, 2 hours post-competition 24 hours post-competition values. In conclusion, the present results suggest that the intake of supportive sports drinks before exercising significantly prevents the observed muscle damage. The study showed that serum myoglobin levels between the experimental and the placebo group is significantly different during the 2 hours post-competition period. [Conclusion] The level of serum creatinine kinase and myoglobin accurately shows the extent of the muscle damage. However, further studies on the effect of isotonic sports drink in different training programs on the cell membrane and the muscle damage are needed
