    Acute Effects of Marathon and Ultramarathon Running on Body Composition in Trained Male Athletes
    (Mdpi, 2025) Duz, Serkan; Ilbak, Ismail; Ogut, Ayse Eda Kinaci; Sagat, Peter; Bartik, Peter
    Background and Objectives: This study aimed to compare acute changes in body composition parameters following marathon (42.195 km) and ultramarathon (61 km) runs in trained male athletes, with particular focus on hydration dynamics and metabolic stress. Materials and Methods: Sixteen male amateur endurance runners were assigned to two groups: marathon (n = 8) and ultramarathon (n = 8). Body composition was assessed at three time points pre-race, immediately post-race, and 24 h post-race using bioelectrical impedance analysis. Measurements included body weight (BW), body mass index (BMI), total body water (TBW), total body fat (TBF), lean body mass (LBM), right arm fat (RAF), left arm fat (LAF), right leg fat (RLF), left leg fat (LLF), and torso fat (TF). Results: Both groups exhibited significant reductions in BW and BMI post-race (p < 0.05), with more pronounced changes observed in the ultramarathon group. Partial restoration of these metrics occurred within 24 h, primarily due to glycogen resynthesis and fluid retention. TBW remained stable immediately post-race but increased notably during recovery, particularly in ultramarathon runners, suggesting more effective hydration responses. Muscle and fat-free mass changes were minimal but more favorable in the ultramarathon group. Both total and regional fat percentages declined significantly post-race in both groups, with ultramarathon runners showing greater reductions. Conclusions: Endurance running induces short-term but substantial alterations in body composition, with ultramarathon participation eliciting more pronounced metabolic and fluid balance responses. These findings highlight the importance of race-specific nutritional and hydration strategies tailored to event type and duration.

    Physical performance predictors in youth breaststroke swimming: motor and biomotor diagnostic differences
    (Bmc, 2025) Karadenizli, Zeynep Inci; Ilbak, Ismail; Jorgic, Bojan M.; Bartik, Peter; Sagat, Peter
    Swimming performance in youth athletes is influenced by a complex interplay of physical, motor, and physiological factors. Among competitive swimming strokes, breaststroke is technically demanding and requires precise coordination, balance, and strength. Understanding which specific motor and biomotor components most strongly predict performance in young swimmers can help coaches and sports scientists design more targeted training and talent identification programs. This study aimed to investigate whether statistically significant differ-ences exist in motor and biomotor characteristics between child swimmers with high and low performance levels in breaststroke swimming. A comparative cross-sectional study design was employed. The sample consisted of 58 child swimmers (age: 11.55 +/- 1.35) who regularly participated in swimming training. Based on their 50-meter breaststroke times, participants were divided into high- and low-performance groups. Motor and biomotor performance levels were assessed using variables such as reaction time, balance, flexibility, agility, hand grip strength, vertical jump height, and 30-meter sprint time. Arm span was also measured as an anthropo-metric parameter, and intergroup comparisons were conducted accordingly. The findings revealed that higher-performing swimmers exhibited statistically signifi-cant differences in certain motor and biomotor traits compared to their low-er-performing peers. Specifically, agility, vertical jump height, balance, and arm span emerged as potential performance determinants closely aligned with the technical re-quirements of breaststroke swimming. These results suggest that specific motor and biomotor parameters particularly agility, vertical jump, balance, and arm span are key discriminators of breaststroke performance. Therefore, training pro-grams should be designed to enhance neuromuscular coordination, reactive strength, and postural control. Additionally, anthropometric factors such as arm span should be considered in talent identification processes. Targeted development of these attributes may contribute to performance optimization in young swimmers.
