Summary: The study investigated the effects of high-volume endurance training on maximal oxygen uptake in physically active 12-15 year old boys and girls, finding that in growing active children during puberty, high volumes of systematic endurance training did not have an additional effect on VO2max compared with similar volume of training mainly aiming at developing motor skills.

Summary: This study aimed to describe the anthropometric differences and assess their correlation with physiological markers among road cyclists of different performance levels. The results showed that there were no significant anthropometric differences between trained, well trained, and professional cyclists, with only recreationally trained cyclists exhibiting larger perimeters and skinfolds than professional cyclists. Additionally, physiological performance did not distinguish between cyclists of different specialties, indicating restrained correlations with anthropometric values.

Summary: This study aimed to develop prediction models for VO2max based on submaximal exercise variables or somatic variables in endurance athletes. The study found that VO2 at anaerobic threshold and respiratory compensation point were the most important variables in the exercise equations, while body weight and body fat had the highest impact on the somatic equation. The derived models were accurate and replicable, providing valuable tools for estimating VO2max in sport and clinical settings.

Summary: The effectiveness of interval training on improving VO2max in well-trained runners is still inconclusive, with some studies reporting significant improvements while others do not. However, a relationship between the interval training session impulse and VO2max improvements was observed through training load analysis, providing practical application for periodization in the training regime of well-trained distance runners.

Summary: The study investigated the effects of hand width placement during plyometric push-ups, finding that upper body force development may be significantly impacted by hand width. Although upper body power output appears to be similar across varying hand widths, hand-width placement may impact plyometric performance measures. This study is the first to explore the effects of varying hand widths on plyometric push-up performance.

Summary: This study examines the electrification and grid integration of waste collection vehicles. The findings show that charging these vehicles with electricity generated by waste management plants can reduce operation costs, but providing balancing power by electric vehicles is not economically viable due to network charges and system complexity.

Summary: This study examines the variability of peak residual load in electricity systems with the addition of variable renewable power sources, such as wind and solar. It suggests that the inter-annual variability in peak residual load may decrease with added solar generation during summer peak load periods, due to correlations between solar availability and peak electric load usage for air conditioning. Additionally, the inter-annual variability in peak residual load may decrease with added wind generation in systems with a winter peaking load.

Summary: One of the most common task constraints in designing small-sided games (SSGs) is to manipulate the pitch size to change the relative area per player. This review aimed to compare the effects of smaller and larger pitch sizes on soccer players' physiological, physical, technical, and tactical responses during SSGs. The results showed that compared to smaller pitches, SSGs played on larger pitches resulted in higher heart rate, perceived exertion, total distance, high-speed running, stretch index, and surface area.

Summary: The aim of this study was to compare the effects of small-sided soccer games (SSSGs) and traditional warm-up (TWU) routines on physical fitness qualities in soccer players. The results showed that the SSSG warm-up group was more effective at improving CODS and CMJ performance, while the TWU group was more effective at improving linear speed. Soccer coaches can choose between SSSG or traditional warm-up activities according to player needs and preferences, but the superior effects of SSSG suggest it might offer greater benefits than TWU in preparing players for optimal physical output.

Summary: This study aimed to compare training load parameters, delayed onset muscle soreness (DOMS), and fatigue status between season periods (1(st) and 2(nd) halves) in U14 soccer players and to analyze the relationships between training load parameters based on season periods (1(st) and 2(nd) halves) with peak height velocity (PHV), DOMS, and fatigue status in under-14 (U14) young elite soccer players. Additionally, it was intended to analyze if fatigue, DOMS and PHV could explain training load parameters across the season.

Summary: This study aimed to examine the relationship between maturity status and training intensity in young football players. The results showed a positive correlation between peak height velocity (PHV) and anaerobic power in the early- and end-season stages, as well as an absolute correlation between maturity offset and anaerobic power. The findings suggest that coaches can enhance the physical performance of players by monitoring training loads and maturity status.

Summary: The aim of this study was to analyze the relationships among physical cognitive ability, academic performance, and physical fitness regarding age and sex. The study included 187 students (53.48% male, 46.52% female) aged between 9 and 15 years old (M = 11.97, SD = 1.99) from a town in Jaen, Andalusia, Spain. The results showed a significant relationship between physical fitness, attention, and concentration. There were differences in cognitive functioning scores between sexes and age categories, with girls and older students performing better.

Summary: Adolescence is a critical stage of physiological and psychological changes, and fitness work is important during this period. Self-perception of physical fitness is crucial for adolescent health and well-being, and a positive perception is associated with increased physical activity. This study aimed to analyze the self-perceived physical fitness of high school students using the FP VAS A scale, and to investigate differences based on sex and school location. The study also examined the correlations between the FP VAS A items, age, and BMI. Results indicated significant differences between sexes, with boys having higher scores in all items except flexibility. Negative correlations were observed between BMI and overall physical fitness, cardiorespiratory endurance, and movement speed. Age also showed a negative correlation with cardiorespiratory endurance. In conclusion, boys had better self-perception of physical fitness than girls, and school location did not influence self-perceived fitness. Most self-perceived fitness abilities were inversely correlated with BMI.

Summary: This study analyzed the relative age effect (RAE) on speed in track and field events. The results showed that RAE exists in males in the U16 and U18 categories, while there is no such effect in females in any category. However, in the shallow event, RAE was found in the U18 female category.

Summary: This study compared the echocardiographic parameters of amputee football players with those of athletes without a disability and sedentary individuals. The results showed that amputee football players had smaller left ventricular end-diastolic diameter and myocardial systolic rate, but higher left ventricular end-systole diameter and atrial contraction rate compared to athletes without a disability. Compared to sedentary individuals, amputee football players had higher aortic diastolic diameter, left ventricular posterior wall thickness, A wave, isovolumic relaxation time, and S wave.

Summary: The aim of this study was to compare the external load in home and away matches and the influence of match results and location on the training load before the next match. Analysis of GPS metrics showed no significant differences between match results and locations. However, training data showed differences in duration, high-speed running distance, and number of accelerations and decelerations when the next match was a loss or at home. This study highlights the importance of considering training data when planning future matches.
