The relationship of rebound jump ability to agility and dexterity in 3- and 5-year-old boys

The study examined the relationship between agility, dexterity, and rebound jumping (RJ) ability in three and five-year-old boys. Participants comprised 31 three-year-old and 37 five-year-old boys. A few metrics such as the Rebound jumping RJ index, the execution time for side jumping, and “jump over and crawl under” were measured. The results revealed significant negative correlations between the RJ index and execution time of both side jumps and the “jump over and crawl under” task in boys of both age categories. Significant negative correlations were observed in the relationship between jumping height during RJ and both side jumps and the “jump over and crawl under” execution times. Similarly, significant positive correlations were observed between the time for ground contact during RJ and both side jumps and the “jump over and crawl under” execution times. Overall, the results suggest that RJ ability is related to agility and dexterity. Furthermore, improving abilities related to the force and motor control exerted during RJ were shown to be a possible factor in improving agility and dexterity later in life.
