Skiing is the most popular branch among winter sports, which is preferred from a young age. The branch has its own unique features with its altitude, seasonal activity time, materials and disciplines. This study was conducted to examine the body profiles and physical skills of adolescent male skiers.15 male skiers (cross-country skiing) with a mean age of 14.53±2.61 (years), average height 158.53±9.66 (cm), and body mass average 54.20±10.85 (kg) participated in the study. Participants' age, height and body mass information were determined by standard methods. In the study, respiratory functions, hand grip strength, back-leg strength and vertical jump height were measured. At the same time, the somatotype (ectomorph, mesamorph, endomorph) and body fat percentage of the participants were determined. Tests, including pre-season and seasonal transitions; It was held once in September, December, March and June.Shapiro-wilk was used to determine the distribution of the data, descriptive and frequency analysis was used to determine the means of the variables, and one-way analysis of variance (ANOVA) was used to determine the differences between measurements. The results were given as arithmetic mean and standard deviation (̅±Ss).As a result, it was determined that the physical skill levels of male ski crossers increased gradually during the periodical examinations during the year., Kayak, kış sporları arasında, küçük yaştan itibaren tercih edilen en popüler branştır. Branş, icra edildiği rakım, mevsime bağlı aktivite zamanı, malzemeleri ve disiplinleri ile başlı başına kendine has özelliklere sahiptir. Bu çalışma, adölesan dönemdeki erkek kayakçıların, vücut profillerini ve fiziksel becerilerini incelemek amacıyla yapılmıştır.Çalışmaya, yaş ortalaması 14,53±2,61 (yıl), boy ortalaması 158,53±9,66 (cm), vücut kütle ortalaması 54,20±10,85 (kg) olan 15 erkek kayakçı (kayak kros) katıldı. Katılımcıların, yaş, boy ve vücut kütlesi bilgileri standart yöntemlerle belirlendi. Çalışmada, solunum fonksiyonları, el kavrama kuvveti, sırt-bacak kuvveti ve dikey sıçrama yüksekliği ölçüldü. Aynı zamanda, katılımcıların somatotip (ektomorf, mezamorf, endomorf) ve vücut yağ yüzdesi belirlendi. Testler, sezon öncesi ve mevsim geçişlerinde olmak üzere; Eylül, Aralık, Mart ve Haziran aylarında birer kez yapıldı. Araştırmadan elde edilen veriler IBM SPSS 24.0 paket programında analiz edildi. Verilerin dağılımını belirlemede shapiro-wilk, değişkenlerin ortalamalarının belirlenmesinde tanımlayıcı ve frekans analizi, ölçümler arası farkların belirlenmesinde ise tekrarlı ölçümlerde tek yönlü varyans analizi (ANOVA) yapıldı. Sonuçlar, aritmetik ortalama ve standart sapma (̅±Ss), olarak verildi.Sonuç olarak, erkek kayak krosçularda yapılan yıl içi dönemsel incelemelerde, fiziksel beceri düzeylerinin kademeli olarak arttığı belirlenmiştir. Yani, anaerobik güç (dikey sıçrama-indirekt), solunum fonksiyonları ve lokal kuvvet gibi becerilerin arttığı görülmüştür.

Wearable technologies are becoming indicators of variables such as the intensity and duration that the athletes want to achieve in their exercise and training. These indicators should be accurately reflected to the athletes in monitoring the exercise load. The purpose of this study was to investigate whether Huawei Honor Band 5 (Huawei) and Xiaomi Mi Smart Band 5 (Xiaomi) could provide valid scores when compared the Polar V800 (Polar), that has been accepted as gold standard for heart rate assessment. This research has a quasi-experimental research model without a control group. In total, 11 females and 19 males (Age: 21,9±3 years, height: 172±9,5 cm, weight: 70,6±12,4 kg) individuals from Erzincan Binali Yıldırım University (EBYU) voluntarily participated in this study Participants wore Polar, Huawei and Xiaomi watches at the same time and on different wrists. The Polar watch is fixed on the right wrist, while Huawei is on the right and Xiaomi is on the left. After recording resting heart rate, participants were asked to perform Yo-Yo intermittent recovery test protocol. During the test 75% and 100% of maximal heart rate scores were recorded. Each shuttle result was measured. One sample t-test, Pearson Correlation Coefficient, Intra Class Correlation Coefficient and Bland-Altman were used for statistical analysis. Results showed that there were no significant differences among each other at resting conditions (Polar: 81,3 bpm, Huawei: 81,9 bpm, Xiaomi: 81,1 bpm) (p>0.05). However significant findings were observed in both 75% (Polar: 142,9 bpm, Huawei: 121,1 bpm, Xiaomi: 121,2 bpm (p, Öz: Bu araştırmanın amacı, kalp atım hızı (KAH) ölçümünde fotopletismografi (PPG) teknolojisini kullanan Huawei Honor Band 5 (Huawei) ve Xiaomi Mi Smart Band 5 (Xiaomi) giyilebilir akıllı saatlerinin (GAS) KAH ölçümünde altın standart olarak referans alınan Polar V800 (Polar) saati karşısında geçerli veriler verip veremeyeceğinin kontrol edilmesidir.

Sixteen roller skiers whose mean of age is 16,00±0,89, mean of height is 168,56±2,22 and mean of weight is 57,25±3,64 attended voluntarily to this study with the aim of researching the effect of eight-week roller-ski trainings on boys' national team skiers’ hemoglobin levels. For the skiers participating in the study, a roller ski training program was applied for eight weeks, six days a week, in accordance with the pretest-posttest model. Blood samples were taken eight weeks before and after the pretest-posttest from skiers. There was no statistically significant difference in the pretest and posttest comparison of the hemoglobin values of the roller skiers participating in the study (P>0.05). Consequently, it was observed that roller ski training at an altitude of 1700 meters did not lead to a change in the level of hemoglobin. Key words: Ski, hemoglobin, exercise.

The aim of this research is to analyze of technical parameter during simulated competition on tennis players. 16 male tennis player volunteers participated in this research by age average 24.38±5.536, height average 1.77±0.064 meters and body weight average 74.13±15.024 kg. The research consists of 2 phases which are competition conditions and normal conditions. First of all, technical levels of the players are determined by International Tennis Number (ITN) test. Then, to determine their technical levels during competitions, they had single matches. During the matches players were examined and their shots were recorded. Video camera was used to determine those shots results truly. In competition and out of competition ITN points comparison about forehand shot technique, backhand shot technique, volley shot technique, serving technique it is determined that out of competition ITN points were significantly more higher. As a result, in competition, players could not show their 100% technical performances. It is thought because of the tiredness of the competition. Besides, while forehand shot errors are examined frequently, backhand, volley, serving shot error levels were the same. This is thought because forehand shot is used more frequently

Bu çalışmanın amacı MaxVO2 düzeyinin anaerobik dayanıklılık üzerine etkisinin incelenmesidir. Araştırmaya yaşları ortalaması 22.00±1.414 yıl, boyları ortalaması 1.79±0.083 m ve vücut ağırlığı ortalamaları 73.58±7.596 kg olan toplam 26 amatör futbolcu gönüllü olarak katıldı. Sporcuların anaerobik dayanıklıları FIFA test bataryasında yer alan üç köşe koşu testi ile ölçüldü. Aerobik dayanıklıları ise Yo-Yo 2 aralıklı toparlanma testi ile ölçüldü. Yapılan ölçümlerden önce sporculara 15 dakika ısınma sağlandı. Sporcuların, istirahat nabzı, ısınma sonrası nabız ve anaerobik dayanıklılık sonrası nabız ölçümleri polar saat ile yapıldı. Ölçümler yıllık periyotlamanın müsabaka döneminde yapıldı. Ölçümlerde fotosel, metre, slalom çubuğu, honi ve polar saat kullanıldı. Çalışmaya katılan sporcuların boy (m) ve vücut ağırlığı (kg) ölçümleri elektronik baskül kullanılarak gerçekleştirilmiştir. Sporcuların MaxVO2 düzeyleri ile anaerobik dayanıklılıkları arasında anlamlı bir ilişki bulunmaktadır (F=5,729; P=0,025). MaxVO2 özelliği anaerobik dayanıklılığı 19 % açıklamakta olup, sporcuların MaxVO2 düzeylerindeki 1 birimlik artış anaerobik dayanıklılığın % 40 oranında değişime yol açmaktadır. Sonuç olarak, Anaerobik dayanıklılığın 19 % oranında MaxVO2 tarafından açıklanıldığı düşünüldüğünde, 81% oranında diğer parametreler (kuvvet, sürat, çabukluk, çeviklik vb) tarafından açıklandığı söylenebilir., The aim of this study was to examine of the effect of MaxVO2 level on anaerobic endurance. A total of 26 amateur male soccer players (mean ± SD; age: 22.00 ± 1.414 years; weight: 73.58 ± 7.596 kg; body height: 1.79 ± 0.083 m) volunteered to participate in this study.
