In recent years, interest in "vegetarianism" has increased considerably, both among the common population and among sportsmen. Athletic performance and post-workout recovery can be improved through optimal nutrition: choosing the right foods and introducing them at the right time can make a difference in terms of sports results, for the same number of sessions and training hours. But those who practice sports can follow a vegetarian diet? The choice to become vegetarian is often based on the mere refusal to consume meat or animal products, a choice attributable to philosophical motivations of different nature. In this manuscript, we will try to determine, by commenting on the scientific data published in recent years, the effects, positive or negative, that could be a consequence from adopting a diet of this type, both in everyday life and in sports.

The working activity, as well as the sports one, foresees that results have to be achieved and be decided/evaluated by others, a personal physical and mental effort is required in a well-defined time and space, constraints and limitations established by the nature of the tasks have to be overcome, and a consistent and defined part of one's own time has to be employed. The aim of this research is to demonstrate how work phenomena (specifically work engagement) can be conveyed to the world of sport, highlighting the applicability of occupational psychology also in a sports context.

To determine the statistical relationships among different consolidated performance tests (Yo-Yo, jump, sprint and agility), and the Powersprint™ device, an isotonic equipment, usually used to increase the muscular strength of athletes, used here as performance test. One hundred individuals were involved in the tests (16 females and 84 males). Ninety-five subjects were practicing different field sports, whereas 3 female and 2 male subjects were inactive. Gender, height and body mass were recorded. Participants completed the following tests: Squat Jump, Counter Movement Jump, 10 m sprint, 15 m sprint, Change of Direction, Yo-Yo Intermittent Recovery Test level 1 and PowerSprint 3.0™. Results of this experiment highlighted that PowerSprint 3.0™ is positively and significantly correlated with Squat Jump, Counter Movement Jump, 10 m sprint, 15 m sprint, Change of Direction, Yo-Yo Intermittent Recovery Test level 1. Additionally, the principal component analysis, as expected, was able to neatly differentiates between male, female and inactive subjects. The selected tests appeared particularly effective in giving information about athlete performances in soccer. Performances measured with the PowerSprint 3.0™ positively and significantly correlated with jumps, COD, sprint and YYIR1 tests. This is an indication of the possible use of this light, inexpensive and portable instrument for measuring athlete performances and checking the effectiveness of training programs.
