Jump strength in secondary students using the hyppy tool. A comparative study

Abstract: Introduction: The study of jump parameters can provide information with a direct correlation on the physical health of individuals. Thus, through its measurement we can obtain significant data about the students of the IES Plaza de la Cruz in Pamplona. Aim: The aim of this work is to obtain the height of a battery of jumps using a sample of young students from the IES Plaza de la Cruz, relating them to other variables studied, such as average age and its standard deviation. A new tool is proposed to measure the jump length of high school students by performing a jump test (BDJ, VUCJ, VUDJ), calculate the height of the jumps and to describe the characteristics of a sample of young people from the IES Plaza de la Cruz. Methods: The sample was made up of 73 students belonging to the 1st year of ESO and 1st year of Baccalaureate. The HYPPY tool was used, which is made up of an inertial sensor and an app that automatically analyzes the jump, developed by the company Movalsys S.A. Results & discussion: The evidence is collected differentiating between age, sex and whether or not the subjects do sports regularly and significant differences are found with respect to the jump between the population of 1st year of ESO and 1st year of Baccalaureate, certain differences with respect to gender and none with regarding the amount of sport. Conclusions: At the key moment of adolescence, the four years between 1st year of ESO and 1st year of Baccalaureate represent a great increase in height and muscle mass, which perfectly explains the difference in jumping power. On the other hand, the clear differences between sexes in the adult population, which are not observed in the child population, are also beginning to be noticed.
