This study presents a deep learning-based approach for the automated detection of Quiet Eye (QE) durations from electrooculography (EOG) signals in archery. QE—the final fixation or tracking of the gaze before executing a motor action—is a critical factor in precision sports. Traditional detection methods, which rely on expert evaluations, are inherently subjective, time-consuming, and inconsistent. To overcome these limitations, EOG data were collected from 10 licensed archers during controlled shooting sessions and preprocessed using a wavelet transform and a Butterworth bandpass filter for noise reduction. We implemented and compared a traditional model (SVM) and five deep learning models—CNN+LSTM, CNN+GRU, Transformer, UNet, and 1D CNN—for QE detection. The CNN+LSTM model achiev...
Effects of myofascial exercises on instep kick biomechanics and myofascial elasticity
Deniz, Volkan | Işık, Aleyna | Kılcı, Abdullah | Kesilmiş, İnci
This study aimed to investigate the effects of an anterior superficial myofascial chain strengthening program on maximum ball speed, myofascial elasticity, muscle activation, and shank kinematics in young soccer players. A total of 32 licensed soccer players, aged 13–14 years, were recruited and randomly assigned to either an exercise group or a control group. Participants in the exercise group underwent an 8-week anterior superficial myofascial chain strengthening program consisting of three progressive phases. At baseline and after the 8-week intervention, the maximum ball speed during the instep kick was measured using a radar gun; muscle activation was assessed via surface electromyography; and shank rotational velocity and acceleration were recorded using an inertial measurement unit....
Yemler Bilgisi Yem Teknolojisi ve Balık Besleme
Bilgüven, Murat
Her havuz alanında ya da yetiştirme biriminden elde edilen balık ve dolayısıyla balık yetiştiriciliğinin kârlılığı, büyük ölçüde kullanılan yemin miktarına bağlıdır. Su ürünleri sistemi ne kadar yoğun olursa yemlemenin önemi o kadar fazla olur ve toplam üretim maliyetinde yem maliyetinin payı da o kadar artar. Bilindiği üzere alabalık başta olmak üzere bazı balıkların yetiştiriciliği için akarsu sistemli tesisler kullanılmakta yada sıcaklığın, su bileşiminin ve akıntının dolayısıyla oksijen yoğunluğunun daha iyi olduğu tatlı su ve kıyılarda ise yüzer ağ kafeslerde yetiştiricilik yapılmaktadır. Su ürünleri yetiştiriciliğinin ileri durumda olduğu ülkelerde entansif yetiştiricilik uygulanmakta ve yetiştirme alanlarında birim hacimde maksimum ürün yetiştirilmeye çalışılmaktadır. Bu tür yetişti...
Role of antioxidant defense system and biochemical adaptation on stress tolerance of high mountain and steppe plants
Keleş, Yüksel
Eleven species were collected from Northwest Anatolian mountains (1500–2000 m) and 18 species were collected from the Central Anatolian steppes (850–1000 m) in June 1998 and 1999. In all the species investigated, the water and dry matter percentages and solute contents were measured. The chlorophyll, b-carotene, ascorbate and a-tocopherol contents and catalase (CAT), superoxide dismutase (SOD) andglutathione reductase (GR)enzymeactivities oftheplants werealsodetermined.Thesteppeplantshadlowerwatercontentcomparedwith alpine plants. The chlorophyll contents of the plants investigated did not change with altitude. However, the carotenoid/chlorophyll ratio of alpine plants was found to be significantly higher. The antioxidant/chlorophyll ratio of the trees and shrubs was higher than that of he...
Wearable Sports Technologies
Ulutaş, Derya Selda Sınar | Acar, Nasuh Evrim
Today, wearable monitoring systems created thanks to technological advances are integrated into the human body and are widely used in many fields from sports to health. These systems, in which multiple disciplines work together simultaneously, provide physiological and biochemical data, enabling the determination of the current situation and the creation of appropriate performance and improvement programs for individuals. In this review study, 23 articles, 4 of which were review articles, published in the Sports Sciences category on the Web of Science database in 2024 were examined using the keywords "wearable technology" and "sports". As a result of the review of these articles, it was determined that 8 articles were not related to the subject of wearable technologies in sports and were r...
