    The Correlational Study of the Vertical Jump Test and Wingate Cycle Test as a Method To Assess Anaerobic Power in Road Cyclists
    (Nevzat Demirci, 2023) Ulusoy, Y.; Koçak, F.
    Road Cycling is an important sport that uses anaerobic and aerobic metabolism and especially sprinter cyclists have higher anaerobic capacity. The assessment of anaerobic power in cyclists often involves the use of the vertical jump and Wingate cycle tests. The lack of research in the field of cycling-specific tests to assess anaerobic performance has led to the improvement of existing research. The objective of this research was to investigate the correlation between the vertical jump test and the Wingate anaerobic cycling tests, both of which are often used to assess anaerobic power in road cyclists. A correlation study was conducted on 15 athletes of the Turkish national road cycling team in the 14-16 age group (15.107 ± 0.717 (SD)). The sample of the study was determined by using the convenient sampling method. On the first day, anthropometric measurements and the vertical jump test were conducted. The Wingate cycle ergometer test, lasting for a duration of 30 seconds, was administered to the participants on the second day. The computer application was used to determine the 30-second peak and average anaerobic power during the test. The results acquired from the study revealed a statistically significant positive relationship between the vertical jump performance and the peak power production measured during the Wingate cycle test (r=0.321, p<0.05). The findings indicate that vertical jump tests may serve as suitable field measurements of anaerobic power for road cyclists, as an alternative to the laboratory-based Wingate anaerobic test. © The Author(s) 2023.

    Effects of Carbohydrate and Caffeine-Based Energy Gel Ingestion on Blood Glucose, Blood Lactate and Performance During Prolonged Cycling
    (Nevzat Demirci, 2023) Ulusoy, Y.; Koçak, F.
    The aim of this study was to investigate the effects of carbohydrate and caffeine-based energy gels on blood glucose, blood lactate, heart rate, rating of perceived exertion (RPE), power output, cadence during prolonged cycling exercise. This research was an experimental study in which 15 competitor cyclists were tested in 3 different conditions. 3 experimental trials in a randomized order, no gel intake and water only use (T1), gel intake every 30 minutes (T2), 1 gel intake 15 minutes before exercise, and gel intake every 45 minutes after first gel intake and 1 carbohydrate + caffeine gel at 75 min (T3). Water use was released within 3 trials. Each exercise trial included 2 hours of cycling followed by 15 min TT. Measurements were made at the beginning, every 30 min, and at the end of the exercise. This research found that energy gels increased blood glucose levels and time trial (TT) performance compared to trials without consuming something. A more frequent gel intake improved blood glucose levels and TT distance. In the TT, blood lactate concentration increased significantly in T3 compared to T1 (p<0.05). Heart rate and RPE did not make a statistical difference (p>0.05). Even though cadence, power output, and TT distance in T3 were not statistically significant, the differences that occur are important in terms of cycling. The research also found no correlation between energy gel feedings and water intake (p>0.05). The results were important for cyclists with the positive effect on endurance performance when energy gels are used in long-term cycling exercises. © The Author(s) 2023.
