Physical Exercise Measurements with Accelerometer and Gyroscope

The data represent records from an accelerometer and gyroscope during seven movement tasks that were standardized by a protocol. These tasks were performed consecutively, and each had to be completed as quickly as possible. Data are obtained from 81 children aged 9-11 years. Description of movement tasks (performed in following order): 4x10 m Run: The track is defined by two cones placed at a distance of 10 meters from each other. The cones must have a height of at least 20 cm. It is advisable to secure the cones to the floor with adhesive tape. It is also recommended to mark the correct placement of the cones on the floor with tape. After the start, an individual begins to run towards the opposite cone, circles it from the left, and continues back to the starting cone. This cone is circled from the right. The run continues back and forth with a touch of the opposite cone. On the final run, the individual must cross over the mark where they started and then accelerate, but more freely, to the start of the second section. Crawling: Immediately after starting the section, the individual lies down on the ground and crawls forward, with the entire torso needing to remain constantly on the mat. The total length of the course is 10 meters. The task ends at most 1 meter before the finish line (marked as No. 3 in the image). Crawling on all fours is not acceptable. Progressive Cone Shuttle Run: The track is marked by a series of five cones placed in a line one after the other. It is advisable to secure the cones to the ground with tape. It is also recommended to mark the correct placement of the cones on the floor with tape. The first cone (marked as 'A' – "return cone") is 1 meter away from the start, the second cone is 2 meters away. Each subsequent cone is always 1 meter away from the previous one (marked 'first' to 'fourth'). After the start, the participant runs to the first cone, touches it, and runs back to the return cone A. In this manner, from cone A, the participant runs progressively to cones two through four, returning to cone A each time. The participant must always touch each cone with one hand. This way, the length of the run progressively increases by 1 meter. After completing the run to the fourth cone, the participant circles outside all the cones and runs to the next station (marked as station 4). All runs are performed on the outside of the cones. Ring Collection and Placement Run: The track is marked by six equally sized sections of a Swedish ladder and one cone located 10 meters away from the start of the section. The individual sections are placed alternately on the left and right side of the line between the start and the end cone, each touching with one corner of the section. Inside each section, at its centre, rings are loosely placed. Immediately after the start, the participant runs and progressively moves through all the sections towards the cone, collecting rings. After circling the cone, the participant returns along the same path, placing the rings back into each section. It's important to emphasize that the rings must not be thrown but placed on the ground. From the last section, the participant runs directly to the next station, number 5. 10x Position Change Drill: The task is performed on a mat. The station is directly in the centre of the mat. Immediately after starting the section, the individual performs 10 cycles of position changes. One cycle consists of transitioning from standing upright to lying on the stomach, rolling over onto the back, and transitioning back to an upright standing position. When performing the cycles, it is necessary to ensure that each position is correctly maintained. After completing the last cycle, the individual immediately moves on to the next station, number 6. 10x Gymnastic Hoops Passing: Immediately after starting the section, the individual performs 10 movement cycles, where one cycle consists of crawling through a gymnastic hoop from a standing position, moving from the head to the feet. At the end of each cycle, the individual always lies on the ground, then steps out of it and stands upright. Only after this does the individual lean towards the hoop again and begin a new cycle. Immediately after the last cycle, there is a run to station number 7. 10x Bench Jumping (pushing off with one foot): Immediately after starting the section, the individual runs to the right edge (outer side) of the bench at its beginning and starts jumping over the bench back and forth. The jump is made from one foot, landing on the other. Between jumps, it is necessary to touch the ground with both feet. The jumps must be performed in a way that the individual continuously moves forward and does not jump in place. After completing the last jump, the individual immediately runs to the final finish mark, where a triple hit to the back is also performed. (identical to station number 2) Crawling: This section is carried out according to the same instructions and at the same location where the previous crawling (section 2) took place. The end of the section is at station number 3, which is also the finish line of the entire course. The main data file is physical_exercise.csv.
