INTRODUCTION: The study aimed to describe the practices and perspectives of Czech football coaches regarding the monitoring of players' training load and physical performance, with a focus on identifying key barriers and preferred sources of information. METHODS: A total of 235 football coaches completed an online survey comprehending training load monitoring methods, physical performance assessments, barriers to implementation, and information sources. RESULTS: Among respondents, 93.7% reported monitoring training load, with training diaries (70%) being the most utilized method for external load measures and heart rate (45%) for internal load. Despite this, 42.7% of coaches did not monitor internal load and 21.7% did not conduct physical fitness evaluations. The most frequently reported barrier was a lack of resources (74.5%), though elite-level coaches (52.8%) and strength and conditioning coaches (75%) identified human resources as their primary limitation. Across all levels, the Football Association was the preferred source of information (61.7%). CONCLUSION: The findings highlight the predominance of traditional monitoring practices among the Czech football coaches, alongside with notable gaps in internal load tracking and fitness evaluation. The resource constraints remain a major barrier. Practical recommendations include promoting economical monitoring tools, such as RPE, and enhancing collaboration among stakeholders to improved monitoring strategies. The Football Association's play a key role on support these efforts.

The inhabitants of the Dinaric Alps (former Yugoslavia and Albania) have long been known as people of impressive body height, but after World War II, there was a critical lack of data related to this phenomenon. This anthropological synthesis includes the measurements of 47,158 individuals (24,642 males and 22,516 females) from the period 2010-2018 and maps detail regional differences in male stature in the Western Balkans. According to these data, young men from Montenegro (182.9 cm) are currently the tallest 18-year-olds in the world, surpassing their Dutch peers (182.4 cm), and 18-year-old boys from Dalmatia are even taller (183.7 cm).at a regional level. A continuous belt of extraordinary height means (>184 cm) stretches from the Adriatic coast of Dalmatia through Herzegovina to the central part of Montenegro. This article summarizes all the key socio-economic, nutritional, and genetic data, and offers possible explanations for this anthropological phenomenon. Since the remarkable height of the Dinaric populations cannot be connected with any commonly known environmental factor, the most probable hypothesis is genetic and links these physical characteristics with the local founder effect of Y haplogroup I-M170. Furthermore, given that both the level of socio-economic development and dietary protein quality are still sub-optimal, the local upward trend in body height has the potential to continue in the future.

This work aimed to identify the influence of selected endogenous (internal load) and exogenous (possession duration, game quarter, and defensive pressure) factors in natural game conditions on the efficiency of dribbling and passing skills. Dribbling and passing skills were assessed during four games of U19 female basketball players and five games of senior (2nd division) female basketball players. In total, 551 dribbling and 914 passing executions were evaluated. Binary logistic regression identified defensive pressure of the opponent as a predictor of dribbling and passing skills effectivity. When the defensive pressure of the opponent was medium, the chances for the ineffective pass were 1.997 times more likely (95% CI; 1.179-3.383), as it is at the minimum defensive pressure. When the defensive pressure of the opponent was high, the chances for ineffective dribbling were 7.45 times more likely (95% CI; 3.672-15.113) and for ineffective pass were 8.419 times more likely (95% CI; 4.6-15.409), as it is at minimum defensive pressure. The game quarter and the internal load were not identified as the predictors influencing the dribbling and passing effectivity. Possession duration was also an insignificant predictor of dribbling and passing skills effectivity. However, the passing skill effectivity decreases when the shot clock is winding down. These findings confirm the importance of transferring game situations into the training process. Coaches should take into account these factors when they want to stimulate determinants of player performance in a balanced and systematic way.

PURPOSE Many types of vertical jumps (VJ) are commonly used to assess the development of the level of explosive strength of lower limbs achieved after a training period. This study is focused on comparing various parameters of different types of VJ with 1 RM in Olympic-style weightlifting, squat and deadlift with an Olympic bar. he snatch r=0.8 r2= 0.64, clean and jerk r=0.81 r2= 0.65, back squat r=0.82 r2= 0.67 and deadlift r=0.78 r2= 0.60; for the SJ with hands on the hips and the snatch r= 0.76 r2= 0.57, clean and jerk r= 0.75 r2= 0.56, back squat r= 0.77 r2= 0.59 and deadlift r= 0.71 r2= 0.50. Significant correlation coefficients were not found for 1 RM in the snatch, clean and jerk, back squat and deadlift and the CMJ or SJ with and without arm swing in any of the following parameters: jump height (m), relative force (% of body weight), relative power output (W/kg of body weight). CONCLUSION The main finding is that the jump height (m) of the CMJ or SJ with or without arm swing did not correlate significantly with 1 RM in the snatch, clean and jerk, back squat and deadlift. Therefore, jump height measurement can be used as a motivation tool but not to predict maximum strength in Olympic bar exercises, or vice versa. We recommend using the average power output (W) parameter in the CMJ with using arms as a predictor of current performance level in exercises with an Olympic bar for men and women.

Délka ruky je vhodným tělesným rozměrem pro odhad výšky postavy ve forenzní antropologii. Takový odhad výšky postavy je však vždy ohrožen populační specifitou běžně užívaných regresních rovnic vypočítaných metodou nejmenších čtverců. Na základě dříve publikovaných statistických parametrů (průměrné hodnoty délky ruky a výšky postavy, regresní koeficienty) z 87 publikovaných studií (212 populačních vzorků) jsme metodami průměrování regresních koeficientů a redukované hlavní osy vytvořili soubor nových transpopulačních rovnic pro odhad výšky postavy z délky ruky. Následně jsme ověřovali přesnost odhadů z těchto nových rovnic na pěti referenčních vzorcích z české, slovenské a bosenské populace a porovnali jejich výsledky s výsledky modelu metody nejmenších čtverců, vyvinuté na českém vzorku. Výsledky ukázaly, že navržené transpopulační rovnice nejsou vhodné pro odhad výšky postavy z délky ruky, pokud nejsou omezeny např. na geograficky užší populační skupinu (v naší studii Evropané slovanského původu). Principiálně obdobné konsekvence doporučujeme zvážit také u odhadů u délek kostí při hodnocení výšky postavy na základě forenzních nálezů skeletu

t has been established that hand length is a suitable parameter for stature estimation in forensic anthropology. However, such estimation is always compromised by population specificity of ordinary regression equations. Based on previously published statistical param- eters (average values, regression coefficients) from 87 studies (212 different samples) available in literature, we developed a set of new cross- population equations for estimation of body height from the hand length (Reduced Major Axis Models, Average Regression Models). Sub- sequently, we tested the accuracy and preciseness of these new equations on five testing samples of primary measurements originating from Czech, Slovak and Bosnian populations and compared the height estimates with the results of traditional Least Squares methods developed on a Czech sample. The results showed that cross-population based models are not suitable for body height estimation from hand length unless they are limited to a narrower geographically confined population group (in our study Europeans of Slavic origin). We propose considering principally similar consequences when estimating the body height from a bone length in forensic skeletal cases.
