Ontogenetic motor development is largely dependent on the location and time of exercise. If the development of motor skills is hindered, for example, by a small space or by the lack of an incentive ...and a coordinator, the deficit of movements will have repercussions on the whole development of the child, because, among other things, movement is an important means of enriching knowledge.
Children learn to walk, speak, and think at an astonishing pace. The D-score presents a unified framework that places children and their developmental milestones from different tools onto the same ...scale, enabling comparisons in child development across populations, groups and individuals. This pioneering text explains why we need the D-score, how we construct it, and how we calculate it. It will be of interest not just to professionals in child development, but also to policymakers in international settings and to data scientists.

Discovering and selecting sports talents in volleyball is the main and most difficult task for specialists in this sport. In the initial selection, and then in monitoring the physical and technical ...development of the athletes, coaches rely on the morphoanthropometric features and indicators characteristic of the model of a highly qualified athlete in volleyball. The rapid pace of development of sport, which is characterized by ever closer specialization in individual sports, requires a deepening of knowledge about the structure of the human body. It is very important that the training work is aimed at individualization of training programs, in accordance with the anthropometric, physiological and psychosocial characteristics of each athlete. The purpose of this study is to develop a characteristic description of the state of anthropometric data of 15-18 year old female volleyball players. The analysis on the established average values and variability of the indicators for anthropometry characterizes the studied group as homogeneous. Minor differences are the reason for some sign dissipation in the indicators "Weight" and "Thigh circumference". The characteristic level of the female players is at a satisfactory level compared to the anthropometric criteria in volleyball.
The increasing trend of population has caused cities to face significant physical development in recent years. In many cities, unplanned physical development has been associated with environmental ...degradation and environmental hazards. One of the areas that has faced with a lot of physical development in recent years is the city of Hendijan in Khuzestan province. In this research, Landsat satellite images, 30 meters high digital model and different information layers are used as the most important research data. The tools used in the research include ArcGIS (to prepare the desired maps), ENVI (to process satellite images and prepare land use maps) and IDRISI (to implement the LCM model). Also, the most important model used in the research was the LCM model, which was used to evaluate the spatial trend of land use changes. The results of this research have shown that the size of the residential areas of Hendijan city has increased by about 1.6 square kilometers during a period of 30 years. The results of the evaluation of land use changes in the region have shown that during the period of 30 years, 1.15 square kilometers of barren lands, 0.4 square kilometers of agricultural lands and 0.05 square kilometers of gardens have been converted into settlements. Also, the results of the evaluation of the spatial trend of changes have shown that the highest development rate of the residential areas was related to the northern areas of the Hendijan.
Childhood malnutrition is associated with high morbidity and mortality globally
. Undernourished children are more likely to experience cognitive, physical, and metabolic developmental impairments ...that can lead to later cardiovascular disease, reduced intellectual ability and school attainment, and reduced economic productivity in adulthood
. Child growth failure (CGF), expressed as stunting, wasting, and underweight in children under five years of age (0-59 months), is a specific subset of undernutrition characterized by insufficient height or weight against age-specific growth reference standards
. The prevalence of stunting, wasting, or underweight in children under five is the proportion of children with a height-for-age, weight-for-height, or weight-for-age z-score, respectively, that is more than two standard deviations below the World Health Organization's median growth reference standards for a healthy population
. Subnational estimates of CGF report substantial heterogeneity within countries, but are available primarily at the first administrative level (for example, states or provinces)
; the uneven geographical distribution of CGF has motivated further calls for assessments that can match the local scale of many public health programmes
. Building from our previous work mapping CGF in Africa
, here we provide the first, to our knowledge, mapped high-spatial-resolution estimates of CGF indicators from 2000 to 2017 across 105 low- and middle-income countries (LMICs), where 99% of affected children live
, aggregated to policy-relevant first and second (for example, districts or counties) administrative-level units and national levels. Despite remarkable declines over the study period, many LMICs remain far from the ambitious World Health Organization Global Nutrition Targets to reduce stunting by 40% and wasting to less than 5% by 2025. Large disparities in prevalence and progress exist across and within countries; our maps identify high-prevalence areas even within nations otherwise succeeding in reducing overall CGF prevalence. By highlighting where the highest-need populations reside, these geospatial estimates can support policy-makers in planning interventions that are adapted locally and in efficiently directing resources towards reducing CGF and its health implications.
This study describes the contemporary practices of strength and conditioning coaches in professional soccer. Fifty-two strength and conditioning coaches from professional leagues across 18 countries ...completed an online survey, consisting of 45 questions, with eight sections: (a) background information, (b) muscular strength and power development, (c) speed development, (d) plyometrics, (e) flexibility development, (f) physical testing, (g) technology use, and (h) programing. A frequency analysis was used to assess and report responses to fixed response questions, and thematic-analysis used for open-ended questions to create clear, identifiable and distinct themes. All strength and conditioning coaches were educated to degree level or higher, 65% held strength and conditioning certifications and 54% held soccer coaching certifications. Concentric (100%) and eccentric (98%) modes of resistance were the most commonly prescribed, whereas the squat (including variations) (52%) was deemed the most important exercise for soccer players. Hang clean (33%) and multiple hops/lunges (89%) were the most programed Olympic weightlifting and plyometric exercises. Global Positioning Systems (94%) were the most utilized technology-based equipment. Time, scheduling and fixtures were the biggest issues faced, which made it difficult to periodize training programs and apply appropriate training loads. Furthermore, strength and conditioning coaches would like to further integrate technology to comprehensively monitor and test players, while also believing that technology will continue to be developed and integrated in the future. Strength and conditioning coaches from professional soccer can use the information from this study to review current practices and also provide ideas for diversifying or modifying future practices.
There has recently been a growing interest in long-term athletic development for youth. Because of their unique physical, psychological, and social differences, children and adolescents should engage ...in appropriately prescribed exercise programs that promote physical development to prevent injury and enhance fitness behaviors that can be retained later in life. Irrespective of whether a child is involved in organized sport or engages in recreational physical activity, there remains a need to adopt a structured, logical, and evidence-based approach to the long-term development of athleticism. This is of particular importance considering the alarmingly high number of youth who fail to meet global physical activity recommendations and consequently present with negative health profiles. However, appropriate exercise prescription is also crucial for those young athletes who are physically underprepared and at risk of overuse injury because of high volumes of competition and an absence of preparatory conditioning. Whether the child accumulates insufficient or excessive amounts of exercise, or falls somewhere between these opposing ends of the spectrum, it is generally accepted that the young bodies of modern day youth are often ill-prepared to tolerate the rigors of sports or physical activity. All youth should engage in regular physical activity and thus should be viewed as "athletes" and afforded the opportunity to enhance athleticism in an individualized, holistic, and child-centered manner. Because of emerging interest in long-term athletic development, an authorship team was tasked on behalf of the National Strength and Conditioning Association (NSCA) to critically synthesize existing literature and current practices within the field and to compose a relevant position statement. This document was subsequently reviewed and formally ratified by the NSCA Board of Directors. A list of 10 pillars of successful long-term athletic development are presented, which summarize the key recommendations detailed within the position statement. With these pillars in place, it is believed that the NSCA can (a) help foster a more unified and holistic approach to long-term athletic development, (b) promote the benefits of a lifetime of healthy physical activity, and
