Öğe A comparative study on the physical fitness and performance of male basketball players in different divisions(Niğde Üniversitesi, 2012) Korkmaz, Cihat; Karahan, MustafaThere is a lack of information about the influence of different practice levels on physical fitness and performance variables of male basketball players competing in different divisions. Hence, the purpose of this study is to compare selected physical fitness and performance variables of male players in Turkey National Basketball League’s Division I (D1), II (D2) and III (D3=Regional) and to evaluate whether players with different divisional characteristics have different physical fitness and performance variables. From the Turkey basketball league, ninety male basketball players who are competing in the division I (n=30), division II (n=30) and division III (n=30) voluntarily participated in the study. Physical fitness (body height, mass and fat percentage) and performance (vertical jump height (VJH), vertical jump power (VJP), VO2max and 20 m sprint) measurements were taken in three separate consecutive days following the completion of the first session. D1 and D3 players overall weighed more and D1 players had more body fat (BF) and lean body mass (LBM) than D2. There were significant differences in VJP between divisions (D1>D2>D3= p<0.05), but, the differences in sprint ability and body height were not significant. Although there was no difference between D1 and D2 in VO2max and VJH, their values were significantly higher than D3 (p<0.05). These results showed that in spite of relatively little differences in the average physical characteristics, there were very large statistical differences between divisions in physical performance variables of male basketball players, especially VJP and LBM which is an important criterion of performance at basketball.Öğe A comparative study: The attitudes of Turkish and foreign male students to the physical education lesson [Komparativna analiza: Stavovi turskih ucenika i stranih ucenika prema nastavi tjelesnog odgoja](Faculty of Teacher Education, 2011) Ünlü,Hüseyin; Karahan, Mustafa; Aydos, Latif; Öner, MutluThis study aims to examine the attitudes that foreign students, obtaining secondary education in Turkey, have to the physical education lessons, compared with Turkish students. The study sample consists of 437 students. 325 of these are male students from 34 different countries and 112 of them are Turkish students. The study used the "Attitude Scale to Physical Education Lesson" as a data collection tool. While data analysis used descriptive statistics, independent t test was used for the comparison of the attitudes of Turkish and foreign students to the physical education lesson. The study revealed that participants in the study have positive attitudes to physical education lessons and, when compared, there is a significant difference between the attitudes of Turkish and foreign students.Öğe Age-related physical performance differences in male soccer players(Kamla-Raj Enterprises, 2016) Karahan, MustafaThe aim of this study is to identify the differences of physical performance characteristics between the amateur male adolescent soccer players in different age groups. One hundred and twenty-eight male players voluntarily participated in this study and athletes were classified in three chronological age groups as U-15, U-17 and U-19. Physical performance data showed that the U-15 group tended to be slower over 10 and 20 meters, and had the poorest agility and anaerobic power. Except for explosive power, the performance values of U-17 were lower than U-19 (p<0.05). In conclusion, there were significant differences between three groups. These agerelated differences were strongly correlated with differences in physical performance characteristics. Results suggest that anaerobic performance and sprint ability improves during maturation of amateur male adolescent soccer players. Thus, the coaches should take into consideration differences in age-related physical performance in player selection for a team or training practices. © Kamla-Raj 2016.Öğe Badminton basic skills learning level of boys with mild intellectual disabilities(2012) Karahan, Mustafa; Salman, Melih Nuri; Ünlü, HüseyinThe purpose of the study was to determine the skill learning level of the badminton basic techniques of boys with mild intellectual disabilities. The study sample consisted of 30 mildly intellectual disabilities (MID) boys. Participants were added to 12 weeks instruction programs those 60 minutes in duration and three days per week. Participants were tested with badminton test on three badminton skill including forehand clear stroke, long and short serves. Tests were carried out every other day in the 6th and 12th weeks of the instruction program. Skill learning levels of MID boys for each stroke were evaluated averagely 38% and 60% at the end of 6th and 12th weeks, respectively. Two way repeated measures ANOVA on both factor tests showed that clear, forehand short and long serve strokes were not affected by each other. Therefore, there were no significant difference among score of each strokes in both pre (F=.089) and post test (F=2.491). However, there was significant difference between pre and post tests scores (p<0.05). The study showed that MID boys could easily learn in badminton basic skills applying commonly used teaching methods with effective learning. © Sila Science.Öğe Changes in physical performance characteristics of female volleyball players during regional division competitions(Universidad de Murcia, 2022) Karahan, Mustafa; Çolak, MergülThis study aims to examine the seasonal changes in the physical performance of female volleyball players competing in the regional division. Forty-three volunteer female players (age: 22 ± 2.1 years, height: 172.9 ± 4 cm, weight: 61.5 ± 6 kg, experience: 8.8 years) competing in the same group of the regional division of the Turkish volleyball league participated in this study. Players participated in a series of test protocols including the 20m shuttle-run, T-run, 20m sprint, vertical jump, and running anaerobic sprint (RAST) in the beginning, mid, and ending of the 16-week competition season. The results showed that all tested physical performance characteristics of the players improved significantly in both the first and second periods of the competition season. However, the improvements in the first period were significantly higher than in the second period for VO2max (4.7 vs 1.5%, p<0.05), anaerobic power (6.6 vs 1.9%, p<0.05), vertical jump height (3.46 vs 1.54%, p<0.05), explosive power (4.48 vs 3.72%, p<0.05), 20-m sprint (2.4 vs 0.98%, p<0.05) and change of direction abilities (0.9 vs 0.7%, p<0.05). This study indicated that the prolonged competition season might induce significant functional improvements in the physical fitness profile of female volleyball players competing in the regional division.Öğe Effect of skill-based training vs. small-sided games on physical performance improvement in young soccer players(Institute of Sport, 2020) Karahan, MustafaRecently, there has been increasing attention to research related to the effect of skill-based or game-based training on soccer players' physical performance. Therefore, this study aimed to compare the effectiveness of skill-based training (SBT) at maximum intensity versus the small-sided game (SSG) on the physical performance characteristics of young soccer players during the pre-season period. Twenty-Two male soccer players (mean age 15.3 ± 3 years) were randomly assigned to either an SBT or SSG fully controlled intervention programme, running parallel for eight weeks and held twice a week. On three non-consecutive days before and after training players completed a test battery consisting of the 20 m sprint, T-run, countermovement jump, running anaerobic sprint test (RAST) and 20 m shuttle run. Data were analysed with a two-way ANOVA test for repeated measures. SBT and SSG interventions induced a significant improvement in the anaerobic power (10.9% vs 6.2%), explosive power (8.5% vs 5.6%), VO2max (6.7% vs 6.5%) and vertical jump (5.3% vs 2.9%), respectively. When the improvements in the physical performance variables of both groups are compared, the SBT group achieved greater improvement than the SSG group in anaerobic power (by 4.7%), in explosive power (by 2.8%), in vertical jumping (by 2.3%), in the 20 m sprint (by 2.2%) and T-Test scores (by 1.7%). However, improvements in the VO2max were similar in both groups. The results of the present study suggest that SBT at maximum intensity may be more effective than SSG in improving the physical performance characteristics of young soccer players in the pre-competitive season.Öğe Eğitilebilir zihinsel engelli erkek çocukların bazı motor becerilerine antrenmanın etkisi(Niğde Ömer Halisdemir Üniversitesi, 2007) Karahan, Mustafa; Demir, Rıfat; Şahin, İbrahim; Süel, EminBu çalışma, antrenmanların Eğitilebilir Zihinsel Engelli (EZE) çocukların bazı motor becerilerine etkisini araştırmak amacıyla planlandı.

The study included 12 elite female futsal players (training group, TG) from university league division I and 12 physically active female sports-school students (control group, CG). The CG completed volleyball and basketball courses (each 2 hours per week) as part of their school programs; the TG completed an 8-week training program (non-sequential, 4 days per week). Aerobic and anaerobic performance variables were measured before and after the training program via a 20m shuttle run and running anaerobic sprint tests (RAST). Average anaerobic power, fatigue index and VO2max of TG improved by 10.7%, 22.1% and 9.6% (p<0.05), respectively. These findings demonstrate that skill-based maximal intensity interval training had significant effects on both aerobic and anaerobic performance variables of female futsal players. The results suggest that this training model may be useful as a training efficiency tool among futsal coaches.Öğe The effect of the prolonged competitive season on semi-elite female volleyball players’ physical performance(Turkish Journal of Sport and Exercise / Türk Spor ve Egzersiz Dergisi, 2018) Karahan, MustafaDespite the literature on the changes in the physical performance characteristics of elite female athletes during the competition period, up to this date, there was no study of the physical performances of both the aerobic and anaerobic contented of the semi- elite female volleyball players over the competitive season. For this reason, this study was carried out in order to determine the effect of prolonged competitive season on semi-elite female volleyball players' physical performance. Volunteer 47 athletes were recruited from same group of division III in Turkey Women Volleyball League. During competitive season, athletes took part in an official match and 3-4 training seasons per week. Body mass, VO2 max, 20m sprint, agility, vertical jumping, explosive power, aerobic and anaerobic power were assessed before and after 22-week competitive season. Normality data was primarily tested with Shapiro-Wilk and evaluated with Wilcoxon test because of abnormal distribution. There was significant improvement in VO2 max (2.26%), 20 m sprint time (2.1%), agility (1.6%), vertical jump (2.99%), explosive power (3.5%), maximal anaerobic power (6.35%), whereas decrease in minimum (-5.8%) and average anaerobic (-30.66%) power (p<0.05), but decrease in body mass wasn't significant. This study indicated that prolonged competitive season had negative effect on anaerobic capacity and positive effect on agility, sprint, VO2 max, vertical jumping and explosive power in the semi-elite female volleyball players.
