Biathlon Performance: Heart Rate, Hit Rate, Speed and Physiological Variables
(Lahore Medical Research Center LLP, 2021) Atasever, Gokhan; Kiyici, Fatih; Bedir, Deniz; Agduman, Fatih
Aim: Biathlon is a sport that combines cross-country skiing and rifle shooting. The athlete is fast in the cross-country skiing section, in the gun shooting section, the heart rate should be low. This study aims to determine the hitting rate of the shots made with different training loads on low altitude in elite biathletes in terms of maximum speed and physiological variables. Methods: To evaluate shooting performances first with the resting pulse and then after 2.5 km skiing respectively with 50%, 70% and 100% pulse rate which is separately calculated for each athlete according to karvonen formula. Results: Our findings show that while there was negative relation between maximum speed and body fat there was a positive relation with lean body mass. It has been determined that low body fat percentage and high lean body mass are effective at the athletes' maximum speed and the pulse level with the highest target shooting accuracy rate was at rest and 70% in the second level. Conclusion: Since the pulse of the athlete who comes to the shooting area cannot be reduced to a resting level in a short time, focusing the 70% pulse zone may be beneficial in terms of shooting accuracy and acceleration after the shot. The lowest results in target shooting accuracy were seen at 50% and 100% loads.
Examination of Anaerobic Power Performances of Elite Winter Athletes

The aim of this study is to examine the anaerobic power performance of elite winter athletes. A total of 40 athletes from Alpine skiing (n:10), ski jumping (n:10), snowboarding (n:10) and Short track (N:10) who are active at elite level in different winter sports participated as volunteers. Wingate anaerobic power test (WAnT) was performed using the Monark 894E brand bicycle ergometer to measure anaerobic power parameters of the lower extremities of the research group. The SPSS for Windows 22.0 package program was used to calculate and evaluate the data obtained. The mean and standard deviation of the variables measured are summarized. The normality distribution of the measured parameters was determined by the Shapiro-Wilks test. One-way variance analysis (ANOVA) was used to determine the differences between sports branches because the Normal distribution was shown. The Tukey test from Post-Hoc tests was applied to determine the source of the difference. In this study, significance level was taken as p<0.05. When comparing between groups; there was no significant difference between peak power (W), peak power (W/kg) and average power (W) values. The minimum power (W) values were significantly different between ski jumping groups; Alpine skiing, snowboarding and short track groups; and fatigue index (%) values between ski jumping groups; and alpine skiing and short track groups. Consequently, anaerobic performance is important for branches that are completed in a short time or require explosive power. While anaerobic strength, which is an important component of performance, is an important factor for all branches, it is seen that it has much more importance especially in winter sports branches where anaerobic strength is used predominantly. Improving anaerobic capacity positively improves athlete performance. Therefore, regular training of athletes in accordance with the energy system specific to the branch also results in different results on the anaerobic strength of the training differences in winter sports branches.
Impacts of Different Intensities of Exercise on Inflammation and Hypoxia Markers in Low Altitude

Background This study aims to determine and compare the effects of exercise modalities with different intensities on the secretion of key inflammation and hypoxia markers in amateur athletes. Methods Twenty-three athletes with a mean age of 20.1 years, living at low altitude (1850 m) participated in this study. The participants' maximal oxygen consumption values (VO2 max) were determined with an incremental cycle exercise test as 54.15 +/- 6.14 mL kg min(-1). Athletes performed four protocols: at rest, 50% VO2 max, 75% VO2 max and 100% VO2 max (until exhaustion) with one-week intervals. 50% VO2 max, 75% VO2 max sessions were performed continuously for 30 min on a bicycle ergometer and 100% VO2 max session was performed by cycling until exhaustion. Blood samples were obtained at rest and immediately after each exercise session. Serum tumor necrosis factor alpha (TNF-alpha), C-reactive protein (CRP), interleukin-10 (IL-10), and hypoxia inducible factor-1 alpha (HIF-1 alpha) levels were measured. Results There were significant differences in serum TNF-alpha levels in 75% VO2 max and 100% VO2 max sessions (489.03 +/- 368.37 and 472.70 +/- 365.21 ng/L, respectively) compared to rest conditions (331.65 +/- 293.52 ng/L). Serum CRP levels of 50% VO2 max and 75% VO2 max sessions (1.19 +/- 0.50; 1.07 +/- 0.52 mg/L) were significantly higher than the rest condition (0.74 +/- 0.35 mg/L). There were significant differences in serum IL-10 levels of rest condition and 50% VO2 max; 50% VO2 max, and 100% VO2 max sessions (328.09 +/- 128.87; 446.36 +/- 142.84; 347.44 +/- 135.69; 324.88 +/- 168.06 pg/mL). Serum HIF-1 alpha levels were significantly higher in 75% VO2 max session compared to rest (1.26 +/- 0.16; 1.08 +/- 0.19 ng/mL) (P < 0.05 for all comparisons). Conclusions Both inflammatory and anti-inflammatory pathway is induced on different exercise intensities. Exercise protocols performed until exhaustion may lead to activation of inflammatory pathways and hypoxia-induced damage.
