Elementi di base per l'allenamento funzionale. Il gioco del ferro
No full textL'allenamento funzionale ha lo scopo di potenziare le capacità atletiche umane, soprattutto grazie ad un'accresciuta coordinazione neuromuscolare. La forza, la potenza, la flessibilità e la resistenza fisica sono allenate come forme di abilità motoria, utilizzando pochi esercizi, a carico naturale o con pesi liberi (come il bilanciere olimpico e le kettlebell) che richiedono grande destrezza e velocità di esecuzione. La metodologia di allenamento proposta nel testo è compatibile con tutti gli altri impegni della vita attiva e consiste prevalentemente di sforzi brevi, intensi e ripetuti, al fine di migliorare la forma fisica e di accrescere la capacità di performance nella pratica sportiva

Attività fisica e dimagrimento
No full textPer dimagrire, ovvero ridurre il grasso corporeo, è necessario consumare più calorie di quelle assimilate tramite l'alimentazione. A tal fine, l'attività aerobica è spesso indicata come la strategia migliore. In effetti però essa si rivela inefficiente sia sul piano fisico, sia su quello fisiologico. L'attività fisica intensa è molto più dispendiosa e quindi più efficiente ai fini della riduzione del grasso corporeo
Kinanthropometry and Sport Practice
Full text linkThis dissertation adopts kinanthropometric methods in order to study and evaluate body size, proportions and composition - in terms of fat and fat free mass - of physically active individuals. In particular, several sport disciplines, like strength training, mountaineering and sprint running have been taken into consideration, at different levels of qualification. In general, the most active individuals show low levels of body fatness, when compared to the general population, thus highlighting the positive effects of sport practice on fitness and general health, especially for what concern the prevention of cardio-vascular and metabolic diseases, which are often related to excessive adiposity and sedentary life styles. Further, the statistical evaluation of the most common and easy-to-measure indices of body fatness, like the BMI (Body Mass Index), has proved their low reliability, especially in physically active individuals, prompting for further research in the field of body composition assessment. Finally, the anthropometric and biomechanical assessment of a sample of Italian sprinters has confirmed their optimal body composition - regardless of their relatively high BMI - and high levels of muscular strength, which are significantly correlated to performances in the 100 m and the 200 m. These findings may improve the way we understand the effects of sport training and physical activity on general health

Strength Training for Children and Adolescents: Benefits and Risks
Full text linkPhysical activity has proved to be an effective means of preventing several diseases and improving general health. In most cases, though, light to moderate efforts are suggested, for both youngsters and adults. Common sense advices call for late inception of intense, strength training-related activities, like weight lifting and plyometrics, which are usually postponed at the end of the growth age, even among sport practitioners. However, such advices seem to have a mainly anecdotal nature. The purpose of this review is to evaluate risks and benefits of early inception of strength training, at adolescence or even earlier, and to verify whether concerns can be grounded scientifically. Current literature does not seem to have any particular aversion against the practice of strength training by children and adolescents, provided that some safety rules are followed, like medical clearance, proper instruction from a qualified professional and progressive overload. At the same time, several studies provide consistent findings supporting the benefits of repeated, intense physical efforts in young subjects. Improved motor skills and body composition, in terms of increased fat free mass, reduced fat mass and enhanced bone health, have been extensively documented, especially if sport practice began early, when the subjects were pubescent. It can be therefore concluded that strength training is a relatively safe and healthy practice for children and adolescents
