Background: Repeated sprint ability (RSA) is defined as the ability to recover and maintain maximal effort during repeated sprints, recognised as a crucial performance component in team sports. The exercise mode used to test RSA may influence performance and the contributions of different energy systems. The primary aim of this study is to address the critical gap between traditional cycling-based anaerobic tests, such as the Wingate test, and the practical, sport-specific demands of running in field-based team sports. Methods: This study involved 32 professional soccer players (age: 21.2 ± 1.3 years; height: 177.8 ± 4.3 cm; and mass: 71.3 ± 6.4 kg). They performed cycling- and running-based repeated sprint tests, with similar total sprint numbers, durations, and recovery times, on different days. Contributions from adenosine triphosphate-phosphocreatine (ATP-PCr), glycolytic, and oxidative systems were estimated through body weight, oxygen uptake (VO
2 ), blood lactate (BLa), and the fast component of excess post-exercise oxygen consumption (EPOC). The VO2 levels and heart rate (HR) were monitored during the rest (10 min), exercise, and recovery (15 min) phases in a breath-by-breath mode using a portable gas exchange system. BLa was measured before (at rest) and 1, 3, 5, 7, and 10 min after the running and cycling tests using a handheld portable analyser. A mono-exponential model estimated the ATP-PCr system contribution, calculated using the fast component of EPOC following the final sprint and the sum of the VO2 -time integral during rest intervals. Results: The cycling tests demonstrated significantly higher values for the peak power (PP), mean power (MP), and rate of perceived exertion (RPE) (p < 0.05), while the heart rate peak and blood lactate responses were similar across all modalities. The fatigue index was notably higher in the running tests (p < 0.05). Furthermore, the running tests showed greater contributions in both the percentage and absolute terms from the adenosine triphosphate-phosphocreatine (ATP-PCr) system (p < 0.01), total energy demand (p < 0.05), and total energy expenditure (TEE) (p < 0.01). Notably, the running tests resulted in an increased phosphocreatine breakdown (p < 0.05) and rapid phosphocreatine replenishment (p < 0.01). A simple linear regression analysis highlighted a significant determination coefficient between these performance variables and the contributions of the energy systems, affirming the robustness of the results. The correlation heatmaps further illustrated these relationships, with higher correlations for the PP and MP across modalities (0.41), emphasising the moderate association between cycling and running tests in these metrics. Conclusions: This study elucidated the similarities and differences in energy system contributions and performance outcomes between a cycling and a running repeated sprint protocol, with a comparable total sprint time and work–rest ratio. The findings reveal that a running repeated sprint test elicits a higher energy demand and a higher contribution from the PCr energy system compared to cycling. Performance variables were not associated between running and cycling tests, suggesting those tests cannot be used interchangeably. [ABSTRACT FROM AUTHOR]- Published

Background and Study Aim Sprinting performance is crucial in many sports, and even marginal improvements in sprint mechanics can provide significant competitive advantages. The aim of this study is to examine the influence of step distance, contact time, and flight time on sprint speed. Material and Methods The study was conducted on 26 athletes (20 males and 6 females). Body composition was measured using a bioimpedance analysis device. Sprint kinematics (step distance, contact time, and flight time) and sprint speed parameters were assessed using an optical measurement system during a 30-meter sprint test. Multiple linear regression analysis was employed to determine the effects of sprint kinematic parameters on sprint speed, as well as the effects of body composition parameters on sprint kinematics and speed. The linear regression models included one dependent variable and three independent variables. Results Linear regression analysis revealed that step distance, contact time, and flight time were significant predictors of sprint speed, with the exception of the first step of sprint running (p < 0.05). Furthermore, the effects of body composition parameters (age, body weight, and height) on sprint kinematics and speed were found to be significant (p < 0.05). The proportions of variance explained by body composition parameters were highest for step distance and sprint speed, with R2 values of 0.719 and 0.686, respectively. Conclusions This study confirms that step distance, contact time, and flight time are significant predictors of sprint speed. Additionally, the results underscore the substantial influence of body composition parameters such as age, body weight, and height on sprint kinematics and speed. These findings highlight the importance of considering both kinematic and physiological factors in the training and development of athletes for optimized sprint performance. [ABSTRACT FROM AUTHOR]

The aim of this study was to investigate the energy system contributions to different repeated sprint protocols and also to determine sex-related differences in these contributions. Sixteen men and fourteen women team sport athletes randomly performed two cycling repeated sprint protocols with the same total duration (10 x 6 s and 6 x 10 s). Relative peak power (RPP), relative mean power (RMP), performance decrement (PD), oxygen uptake (VO
2 ), blood lactate (LA), heart rate (HR) and ratings of perceived exertion (RPEs) were measured. The contributions of energy systems were calculated from oxygen consumption and lactate values during rest, exercise and recovery phases based on mathematical methods. Findings indicate that men had higher RPP and RMP. RPP did not differ according to protocols, while RMP was higher in the 10 x 6 s protocol. The sex effect in PD was similar; however, it was higher in the 6 x 10 s protocol. The effects of protocols on the maximum HR and LA were similar; however, the 6 x 10 s protocol resulted in higher RPEs. In both protocols women had higher ATP-PCr and men had higher glycolytic system contribution with similar oxidative system contribution. In addition, the 10 x 6 s protocol had higher ATP-PCr system contribution and the 6 x 10 s protocol had higher glycolytic system and oxidative system contributions. In conclusion, the contribution of energy systems, physiological and performance variables showed variations according to sex and different protocols. [ABSTRACT FROM AUTHOR]- Published

Only a few studies have produced equations that can estimate resting metabolic rate (RMR) in female athletes, but the accuracy of these equations for combat athletes has not yet been tested. The aim of this study was to evaluate the 12 different equations which are commonly using to determine resting metabolite rate (RMR) in the literature. Twenty-three female combat sport athletes (24.23± 3.39 years; 166.8 ± 5.3 cm; 63.13±6.53 kg; 8.78±3.19 experience years.; 56.40±3.43 VO2 mL/kg/min) were participated this study in voluntarily basis. A cross-validation approach used to compare the accuracy of 12 commonly prediction equations with measured RMR by indirect calorimetry to determine RMR in female combat sports athletes. All the predictive equation was underestimated RMR when compared with the measured RMR (p < 0.05) and the smallest mean difference (92.46 ± 210.38 kcal·d-1) was observed for Altman & Dittmer equation amongst the 12 predictive equations. The Altman & Dittmer equation was accurately predicted 16 out of 30 subjects' RMR value within the range ±10%. However, based on the Bland-Altman plots, the prediction equations were not accurately nor precisely predicted RMR in the current sample of female combat sport athletes. The results in the present study showed that the Altman & Dittmer equation is most suitable equation to predict RMR amongst 12 equations. Although the Altman & Dittmer equation was resulted with smallest mean difference, it seems that there is need to further research with longitudinal approach to understand the effects of training intensity and body mass changes on RMR in order to develop the formulas already exist used commonly.

- Abstract
This study aims to compare the physical and physiological profiles between elite men and women wrestlers of free style category. The research group consist of twenty-nine men and twenty-one women freestyle wrestlers who camped for performance tests at the Turkish Olympic Preparation Center in Ankara 2 months before the European Wrestling Championship in Budapest on March 28-April 3, 2022. Subjects performed the leg and arm Wingate anaerobic test (anaerobic power and capacity), VO
2max (aerobic endurance), Reactive agility, isokinetic and isometric strength test. The results showed that Lower Extremity anaerobic power obtained from men, knee flexor at VO2max , 60°/s and 180°/s peak torque, isometric force values of arm and trunk extensor muscles, are higher than in women (p<0.05). In contrast, upper extremity anaerobic power values seem to be similar (p>0.05). As a result, it can be said that the endurance capacity, isometric, and isokinetic strength parameters are more effective than the force parameter in gender. These results can be used by coaches, strength and conditioning specialists, and sport scientists to create a comprehensive physical and physiological profile of wrestlers that will help them adapt their training programs.

Çalışmanın amacı genç erkek voleybolcuların düşerek sıçrama performanslarında ortaya koyulan iş ve güç kapasitelerinin yerle temas süreleri ve düşme yüksekliklerine göre incelenmesidir. Çalışmaya dahil edilen 13 milli voleybolcu Xyaş=15.9±0.5 yıl 20, 40 ve 60 santimetre yüksekliklerindeki kutulardan düşerek sıçrama uygulamışlardır. Voleybolculara her kutu yüksekliği için a “Sıçraya bildiğin kadar yukarıya sıçra” b “Önceki sıçramandan çok daha hızlı olarak en yükseğe sıçra” talimatları verilmiştir. Her bir kutu yüksekliğinde yapılan ikişer denemeden elde edilen değişkenler; normal temas süresi NT ve kısa temas süresi KT şeklinde oluşturulmuştur. Elde edilen güç ve yapılan iş değerlerinin temas sürelerine göre farklılıkları ilişkili örneklemler için t-test ile, üç farklı kutu yüksekliğine göre değişimleri ise tekrarlı ölçümlerde ANOVA ile analiz edilmiştir. Her bir atlama yüksekliğinde yapılan atlamalarda kısa temas ve normal temas süreleri arasında istatistiksel olarak anlamlı farklar bulunurken, kutu yüksekliğine bağlı yapılan yerle temas sürelerinde anlamlı farklılık görülmemiştir. Çalışma sonuçları, düşme yüksekliğinin yerle temas sürelerine etki etmediğini ancak maksimum rölatif yapılan iş ve güç değerlerinde farklar oluşturduğunu göstermiştir. KT sırasındaki sıçramalar tüm kutu yükseklilerinde NT sıçramalara göre daha fazla göreceli güç W/kg üretmiş, ve yine 40 ve 60cm yüksekliklerinde KT sıçramalarının yerle temas süresi boyunca NT gruba oranla daha fazla iş J/kg ortaya koydukları görülmüştür., The aim of the study is to investigate the work and power capacities of drop jump performances according to drop jump height and contact time durations in Youth Turkish National volleyball players.13 national volleyball players Xage=15.9±0.5 years performed a series of drop jumps from heights of 20, 40, and 60cm. Two instructions, a ‘‘jump as high as you can’’ and b ‘‘jump high faster than your previous one’’, were given to the participants for each box heights. Two variables determined as moderate ground contact time MC and the shorter ground contact time SC . Paired-Sample T-test was conducted to analyze the differences in power and work outputs in terms of contact time durations and RepeatedMeasured ANOVA was also used to determine the differences according to box heights. While there were statistically significant differences between SC and MC in jumps performed for each drop heights, there was no significant difference in contact times according to box heights. The results of the study showed that drop height did not affect the contact times but made differences in maximum relative work and power. SC produced greater relative power than MC at all drop heights and greater relative works at 40 and 60cm box heights throughout the contact time duration

Araştırmanın amacını erkek futbolcularda kısa ve uzun süreli egzersizin postural kontrol üzerine etkisini incelemek oluşturmaktadır. Araştırma grubunu Xyaş=21,09±3,78 yıl; Xboy=178,59±6,52cm; Xva=73,06±7,43 kg 22 erkek futbolcu oluşturmaktadır. Araştırma grubunun vücut kompozisyon ölçümleri için Tanita MC-980 marka analiz cihazı, postural kontrol testi için kistler marka force plate kullanılmıştır. Kısa süreli egzersiz için wingate bisiklet ergometresi uzun süreli egzersiz için mekik testi kullanılmıştır. Sporcuların test öncesi ve sonrasında laktat ölçümleri için nova biomedical marka Lactate plus cihazı, Kalp atım hızları için polar team kullanılmıştır. Kısa ve uzun süreli egzersizin postural kontrol değerlerini bütün yönlerde salınım oranını daha fazla etkilerken; kısa süreli egzersizin daha çok toplam ve anterior-posterior salınım değerlerini, uzun süreli egzersizde ise medial-lateral salınım değerlerinin daha çok etkilenmektedir. Sonuç olarak iki farklı egzersizin etkileri ayrı ayrı incelendiğinde; medial-lateral salınım değerlerinde kısa süreli egzersizin, toplam ve anterior- posterior salınım değerlerinde ise uzun süreli egzersizin daha fazla artışa neden olduğu belirlenmiştir. Anahtar Kelimeler: Postural Salınım, Egzersiz, Futbol, The purpose of research w as to examine the effect of short and long-term exercise on postural control in male soccer players. Research Group Xage=21,09±3,78 years; Xlength=178,59±6,52cm; Xweight=73,06±7,43 kg consists of 22 male soccer players. Tanita MC-980 brand analysis device for the body composition measurements of the research group. For postural control test w ere used force plate. For short-term exercise, the Wingate bicycle Ergometer w as used for short-term exercise and shuttle run test w as used for longterm exercise. For lactate measurements before and after testing of athletes Nova Biomedical brand lactate plus w as used for pre-test and post-test lactate measurements of the athletes. Polar Team2 w as used to monitoring heart rate of the athletes. The postural control values of short and long-term exercise affect the control rate more in all directions; The short-term exercise is more affected by the overall and anterior-posterior control values and the mediallateral control values in long-term exercise. As a result, the effects of tw o different exercises are examined individually; In the medial-lateral control values, the short-term exercise w as determined to cause a greater increase in the overall and anterior-posterior controls of the long-term exercise
