Abstract
Sports training is a complex phenomenon which, to be effective for the planned purposes, must consider all the aspects that make it up. Agility, rapid strength, and reactive strength are factors that contribute, at various levels and in an integrated mood, to the achievement of sporting performance. Often, these aspects are considered separately and not always satisfactory results in the competitive phase, as there is not sufficient knowledge of the relationship between agility and levels of explosive and reactive strength. The aim was to show how these factors (agility, explosive and reactive strength) had interactions with each other that could be exploited in the development and refinement phase. The study was conducted on a sample of 30 students from the University of Salerno who were administered a battery of instrumental tests through the Optojump platform to recruit quantitative data regarding explosive strength, reactive strength, and agility. One way, Anova and post hoc Bonferroni were performed as statistical tools to analyze data. The results showed a significant difference between the groups (p <0.001) regarding the jump height in the tests performed. Bonferroni's test for multiple comparisons found insignificant differences between only two variables: SJ and CMJ. The results may be useful to sports training professionals and athletes to improve sports training programs.
Highlights
Rapid strength, reactive strength, and agility represent complex psychophysical abilities [1]
The data referred to jump heights for each trial expressed in centimeters
These results led to the rejection of the null hypothesis of equality of the means between the groups with a high ratio between variances (F = 147.151) and a p < 0.05
Summary
Reactive strength, and agility represent complex psychophysical abilities [1] They are important characteristics present in most physical and sports actions that presuppose a good level of development of structural and coordinative elements. Agility is defined as the ability to start, stop and change direction quickly, or the ability to change direction quickly and accurately [6, 7] in response to a stimulus [8] It can take many forms, from simple leg movement actions to full-body movement actions in the opposite direction while running at high speed. Agility represents a complex feature that involves speed and balances, coordination, and the ability to react to a change in the environment [9, 10, 11] This ability is an important component in most sports, such as field sports [12, 13]. It is clear that both the explosive and the reactive strength, linked to intramuscular and intermuscular coordination mechanisms, could influence the development and expression of agility
