Development of The Pediatric Physical Activity Tracking Platform (Pedi@Ctivity) and Smartwatch-based Big Data Analysis

Health Parameters

The adolescents included in the project will be given a smart watch and will be asked to use the watches for 3 months, and a training will be given to the adolescents on the use of smart watches by the project team. The data obtained on health-related parameters and physical activity behaviors of adolescents for 3 months through smart watches will be transferred to the cloud and web platform with the mobile application. With wearable activity tracker watches, data on the person's heart rate during the day, the number of steps taken per day, oxygen saturation, daily calories burned, activities performed and the locations where the activity is performed can be presented. There are many smart watches compatible with the Android OS operating system, it is planned to use 4 different smart watches in our project. With the mobile application we will develop in our project, the health parameters of adolescents using smart watches will be transferred to the platform.

FitnessGram Physical Activity Test Battery-Progressive Aerobic Cardiovascular Endurance Running (PACER)

PACER is an adapted version of the 20 meter shuttle run test and is a field test consisting of multiple stages. The participant will run back and forth in a 20 meter area accompanied by the music coming from the voice recorder. The beep indicates when the participant should finish a lap. The test will start at slow speeds and will gradually increase each minute. The test will be terminated when the participant cannot continue to run at the level he has reached. The number of laps completed at the end of the test will be recorded. PACER is a more fun alternative to other distance running tests. It is recommended for use in children, adolescents and young adults. PACER will be used to assess the aerobic capacity of adolescents.

FitnessGram Physical Activity Test Battery-Push-up Test

The participant will begin the test in the prone position, with their hands shoulder-width or wider than shoulder-width apart, fingers stretched, palms on the floor, and legs slightly apart. During the test, the participant lowers his torso towards the ground and raises himself up again when his elbows are bent 90º. The movement is repeated as much as possible. The rhythm is set to 20 push-ups per minute or 1 push-up per 3 seconds. The test is terminated when the participant makes a mistake twice. The number of push-ups performed at the end of the test will be recorded. The push-up test will be used to evaluate the upper extremity muscle strength and endurance of adolescents.

FitnessGram Physical Activity Test Battery-Back Saver Sit and Reach Test

During the test, the participant takes off his shoes and sits in front of the test apparatus. A box is needed for the test. This box is 35 cm long, 45 cm wide, 32 cm high. A top plate 55 cm long and 45 cm wide is put on top of the box. One leg of the participant is completely straight while the other is bent at the knee. The participant reaches forward four times with their hands on top of each other, holding the fourth reach position for 1 second. At the end of the test, the distance traveled will be recorded. The Back Saver Sit and Reach Test will be used to evaluate the hamstring flexibility of adolescents.

KFORCE Muscle Controller

The KFORCE Muscle Controller is a handheld dynamometer for the evaluation of muscle strength. It assesses maximum strength, endurance, and muscle symmetry. The Muscle controller is versatile and adaptable to many configurations. As a result of the evaluation, the participant's results are recorded in a database. Then, the progress of the participant can be followed in the database of the application. Muscle strength of adolescents will be evaluated with the device.

KFORCE Plates

KFORCE Plates is a strength platform used to improve balance and assess lower extremity muscle symmetry and strength. It consists of two independent plates. KFORCE plates allow the measurement of static and dynamic balance in a wide range of movements. In addition, it can determine the center of gravity and measure the weight distribution in the stance phase. It evaluates squatting, push-ups and jumping characteristics and presents a report containing multiple data as a result of the measurement. Static and dynamic balance analyzes of adolescents will be made with the device.
