The purpose of this study was to compare the effects of two different unstable surfaces balance training on static and dynamic balance abilities. Methods: The 52 healthy active university students were randomly divided into three groups: the training groups exercised on the firm (balance board) or soft ground (balance ball, BOSU®) for 16 min for 3 days per week for eight weeks, involving structured balance exercises. The control group did not perform the balance exercises in this process. All of the groups were tested static and dynamic balance tests by a computerized balance system before and after the training period. Tests were carried out using a single and double-leg stance either with the eyes open or closed. Results: One-way and mixed-design analyses of variance tests indicated that significantly similar improvements were observed in the exercise groups' static (ellipse area and perimeter length) and dynamic (stability index and average track error) balance (p <0.05). No significant changes were observed in the control group in any of the variables tested at any point (p >0.05). Conclusion: Finding shows that using balance board and balance ball as balance training intervention tools have similar effectiveness for static and dynamic balance enhancement in healthy active university students.

During the pandemic period, football referees, like professional athletes, had to take a break from training for a long time. “Repetitive sprinting skill”, “high-intensity repetitive running performance” and “high aerobic power” have an important place in the performance of the referees, and it has been observed that the developments gained after 2 weeks in detraining situation begin to be lost. On the other hand, increased fat ratios and strength differences between the extremities are considered to be the risk of disability and low performance. The aim of this study is to ensure that the performances of elite athletes are preserved with resistance training when they are away from field training for a long time, such as during mandatory situations during the pandemic period, end of seasons, and during injury periods. Participants performed a study consisting of 24 AMRAP-style functional resistance training, limited to a maximum of 9 m2 area, with the aim of metabolic conditioning, and 12 injury-preventing exercises in 42 days. Age, height, body weight, and fat ratios were 35.6 ± 5.01 years, and 184.65 ± 4.42 cm, respectively. A total of 38 elite referees, 8 of whom were FIFA licensed, with a weight of 80.88 ± 7.12 kg and 12.9 ± 3.08%, participated. When the participants' pre-and post-exercise measurements were compared, post-exercise body weight (p = 0.017), fat percentage (p = 0.000), jump performance (p = 0.000), doggy running (p = 0.000), MaxVO2 value (p = 0.000) and warm-up While there was a statistically significant difference in the RPE value after the procedure, no statistically significant difference was found in other parameters. As a result, it was found that planned functional strength training focused on metabolic conditioning significantly reduced anaerobic capacity and aerobic power losses in elite athletes. Accordingly, it is seen that home/hotel room training, which will be planned in holiday periods ranging from 1 to 3 months before starting the beginning of the season training, can be a simple and effective method for the athletes to start the next season in the readiest way.

Bu çalışmada amaç, voleybolda en çok kullanıldığı bildirilen besinsel destekler (C ve D vitamini, demir, magnezyum, kafein, sporcu ve enerji içecekleri, dallı zincirli aminoasitler, HMB, glutamin, whey, kreatin, bikarbonat, karnitin) hakkında bilgi vermektedir. Derlemenin içeriği, daha önce çok sayıda araştırmanın toplanıp yorumlandığı besinsel desteklerle ilgili derleme ve ilgili yayınların referans listeleri ile voleybolcular üzerinde yapılmış araştırma makaleleri özetlenerek oluşturulmuştur. İçeriğin hazırlanmasında derlemelerden yararlanılmasının nedeni, çok sayıda ve farklı sonuçlara ulaşan araştırma makalelerinin seçiminde ortaya çıkabilecek bireysel yanlılığı ortadan kaldırmaktır. Voleybolcular üzerindeki çalışma sayısının azlığı nedeniyle voleybolda besinsel destek (takviye/suplement) kullanımına özgü bilgi yetersiz olsa da, suplementler ile ilgili verilen bilgilerin okuyana fikir verecek yeterlilikte olduğu düşünülmektedir. Sonuç olarak, suplementlerin yararlarını araştıran çalışmalar yapılmaya devam etmektedir ve kullanım yanıtları yöntemsel ve bireysel farklılık gösterebilmektedir. Diğer takviyelerin vücutta eksikliği olmadığı sürece sporcuda sağlık veya performansı iyileştirmesi olası değildir. Hatta antrenmana daptasyonunu köreltmesi nedeniyle performansa, yaralanma riskini artırması nedeniyle de sağlığa zararlı etkileri olabilir.
