A systematic review of Futsal literature

Abstract: This document systematically reviews literature to provide a summary of evidence based research related to the sport of futsal. The review draws on diverse subjects including coaching, physiological, psychological, technical and tactical elements of the sport as well as reviewing subjects relating to the development of futsal. The methodology included a scoping study and review protocol to systematically review 601 documents relating to futsal; 44 of these documents were reviewed in the study. The review aims to provide a resource for fellow researchers, to study the sport and encourage further English language studies in futsal. To that end, gaps in the literature are highlighted by the researchers, and therefore this document acts as a guide for further study.

Physical Self-Concept and Its Relationship to Exercise Dependence Symptoms in Young Regular Physical Exercisers

Abstract: The study aimed to investigate whether certain physical self-concept predicted exercise dependence among young regular exercisers using a multidimensional prospective. One hundred fifty-two regular gym users, 78 were male and 74 female, completed: Physical Self-Description Questionnaire (PSDQ), Exercise Dependence Scale-21 (EDS-21), and Eating Disorder Inventory–2 (EDI-2). Correlation and regression analyses were calculated to determine the relationship between physical self-concept and exercise dependence behaviors. Significant correlations were found, confirming that exercise dependence symptoms and physical self-concept domains were related each other. In addition, results showed that multidimensional model of self-concept is a strong predictor for exercise dependence both for male and female.

Effects of High-Intensity Aquatic Exercises on Bone Mineral Density in Postmenopausal Women with and without Vertebral Fractures

Abstract: This prospective controlled study evaluated the efficacy of a high-intensity aquatic exercise program on the safety of vertebral parameters, anthropometry and physical fitness of 108 non exercising postmenopausal women with and without fractures. Participants were divided into intervention group (IG=64) and control group (DG=44) assessed in a first evaluation and after 24 weeks of intervention, data about bone densitometry, morpheme try(fractures), anthropometry, physical fitness, number of falls and pain perception. IG with fractures after training showed better results than CG with fractures for bone mineral density and t-score of the femoral head(p <0.05). Following protocol, IG without fractures showed better results than CG without fractures in flexibility tests, spine extension strength, hip flexor strength, left and right handgrip strength, and decrease in the number of fall sand pain perception (p <0.05). IG without fractures also obtained better results for right handgrip strength and decreased pain perception in comparison to CG with fractures. High-intensity aquatic exercises contribute to decrease pain and number of falls, improve physical fitness, and increase bone mineral density in postmenopausal women with and without vertebral fractures, with better performance in relation to group not submitted to exercises for the parameters studied.

Growth Development and Maturity in Children and Adolescent: Relation to Sports and Physical Activity

Abstract: Growth and physical maturation are dynamic processes encompassing a broad spectrum of cellular and somatic changes. The most obvious signs of physical growth are changes in overall body size. The children of the same age may differ in rate of physical growth. Ethnic variations in growth rate are also common. Thus growth norms (age-related averages for height and weight) must be applied cautiously. Physical growth, like other aspects of development, results from a complex interplay between genetic and environmental factors. Moreover, the endocrine glands also control the vast physical changes of childhood and adolescence. Although heredity remains important, environmental factors continue to affect genetic expression. Good nutrition, relative freedom from disease, and emotional well-being are essential to children’s healthy development. Changes in size, proportions, and muscle strength support an explosion of new gross-motor skills. Physical activity is needed for normal growth and development, and for young people to reach their potential in muscle and bone development. Further, the psychological, social, and physical development process project powerful influences on sport participation. Sports scientists, physicians and physical educators must be familiar with the normal patterns of growth and development of the child and adolescent. This allow finding out deviations during the pre-participation examination, guiding children into appropriate activities, aiding them in setting realistic goals concerning sports participation. It also provides guidance to the community and coaches in the design of safe and effective training programme.

Impact of Pubertal Growth on Physical Fitness

Abstract: Puberty is a combination of physical, physiological and psychological changes with detectable alterations in physical growth, which is a determining factor for assessment of physical fitness. Several studies have documented the functionality of physical activity for pubertal growth. But the present review has aimed to investigate whether normal pubertal growth, along with its endocrinological variations affect the level of physical fitness and what are the major fitness variables mostly regulated by the hormonal changes during puberty. Different sex hormones in boys and girls have been found to play the key role for regulation of various fitness determinants like body composition, muscle strength, bone development, erythropoiesis, cardiac function, substrate utilization etc. The major fitness components- strength, aerobic and anaerobic fitness, all have been found to be largely associated and influenced by the growth related endocrinological alterations during puberty.
