About this study

Official title: Training and Detraining Effects of a Ten-week Physical Activity Program Implemented Through Mobile Applications on Body Composition and Fitness of Adolescents Aged 12-16 Years.

The use of mobile applications to promote the practice of physical activity has begun to be used in the adolescent population in recent years. This has made it possible to carry out interventions inside and outside the educational setting, the latter being the ones that have brought the greatest benefits. Thus, it has been observed that the promotion of the use of mobile applications in out-of-school hours from the subject of physical education has reported significant benefits on body composition and fitness in the adolescent population. However, there is no known research that has analyzed whether the effect achieved with mobile applications when their use is mandatory disappears when they are no longer promoted from the physical education subject. Therefore, this project goes further and tries to find out whether after the ten-week period of mandatory use of the applications, adolescents continue to use the applications autonomously and the beneficial effects achieved are maintained or disappear due to the lack of use.

For this purpose, a 10-week intervention was planned in which the adolescents used the mobile applications. Prior to the start of the intervention, the adolescents' body composition and fitness (pre) were measured. At the end of the intervention of mandatory use of the mobile applications, the adolescents were measured again (post). And after the post measurement, the adolescents were left for 10 weeks during which they could use the applications autonomously. A third measurement of the adolescents was performed after this 10-week period (post 2).

The aim of this project was to find out the effects of stopping the use of the mobile fitness apps on body composition and fitness of the adolescents.

  • The use of mobile applications promoted from the physical education classroom to improve adolescent health.Behavioural

    Before starting the intervention, a total of 465 adolescents participated in pretest measurements (T1).

    Researchers in charge of explaining how the apps worked were not involved in the measurements or subsequent analysis, as they knew which student belonged to each App and control group. Once each app had been described and its use explained, a training plan was drawn up to be followed during the period of mandatory use.

    The adolescents were motivated to utilize the app for a duration of ten weeks, aiming for a minimum usage of three times per week.

    After the mandatory intervention with the mobile apps, post-test measurements were carried out (T2). Then, a period of 10 weeks was provided in which the use of the app was neither mandatory nor promoted from the physical education subject, after which the post-test 2 measurements (T3) were taken.

Control GroupNo interventionThe control group did not use any of the research mobile applications, but were measured at pre, post and post 2. They continued attending physical education classes normally and practicing their sports activities.
Cardiovascular training through the application "MapMyWalk"ExperimentalThe adolescents who used this application were required to record their weekly workouts. To do this, before starting the workout, they entered the application, selected "walking" and started the record. The application included different warnings and alerts to encourage the practice of physical activity. Each week they had to make a weekly report with the distance covered.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Physical Activity Level (International Physical Activity Questionnaire for Adolescents)

    The Physical Activity Questionnaire for Adolescents will be used to establish the level of sports practice of the adolescents. This questionnaire includes eleven questions related to the practice of physical activity in school, after school, household chores and travel. The questionnaire makes it possible to classify adolescents as inactive or active (light, moderate or vigorous intensity).

    Measured: Through study completion, an average of 1 year

  2. Physical condition (Maximal oxygen consumption)

    The 20-m shuttle run test evaluates maximal aerobic capacity by means of an incremental 20-meter out-and-back test. The initial speed of the test is 8.5 km/h and is increased every minute by an audible signal. The test ends when the subject stops or fails to reach the reference line two consecutive times. The speed recorded is the speed reached in the last stage that the subject is able to complete. Through the equations of Leger et al. the reference value of the subject's VO2 max. is obtained.

    Measured: Through study completion, an average of 1 year

  3. Physical condition (Lower extremity muscle strength)

    The countermovement jump test (CMJ) will be used to measure this variable. This test provides information on the explosive strength of the lower body. The CMJ is a vertical jump that begins with the subject in a standing position, followed by knee flexion to a position of approximately 90 degrees, and a rapid extension of the knees to perform a jump in which the maximum height is reached. It should be noted that there is no stop in the knee flexion position since the intention is to take advantage of the explosive elastic reflex energy of the movement. The subjects will perform two repetitions of the jump 2 minutes apart. A MuscleLab force platform (Ergotest Innovation S.A., Norway) will be used to record the data, which will measure the time of flight from the time the subject takes off from the platform to the time the subject re-enters contact with the platform.

    Measured: Through study completion, an average of 1 year

  4. Physical condition (abdominal strength)

    To assess abdominal muscle endurance will be use Curl-up. The highest number of repetitions the subject completes in one minute will be recorded.

    Measured: Through study completion, an average of 1 year

  5. Physical condition (upper extremity muscle strength)

    To assess upper limb strength will be used Push-up test. The subject will perform as many repetitions as possible in one minute, or until reaching exhaustion.

    Measured: Through study completion, an average of 1 year

  6. Anthropometric Variables (Height)

    To measure height, a SECA measuring rod should be used. Adolescents should stand barefoot with their backs against the measuring rod, heels of their feet together and their gaze straight ahead. Measurements will be obtained in centimeters and will be repeated 2 times for each subject. A third measurement will only be taken if the difference between the first and second measurement is greater than 1%.

    Measured: Through study completion, an average of 1 year

  7. Anthropometric Variables (Weight)

    A Tanita BC 418-MA Segmental scale (Tanita, Tokyo) will be used to measure body weight. The subject will step on the scale with both feet inside the scale and looking straight ahead, without leaning the body. Values will be obtained in kilograms and two measurements will be carried out on each subject. If the difference between both measurements is greater than 1%, a third measurement will be taken.

    Measured: Through study completion, an average of 1 year

  8. Anthropometric Variables (Fat mass)

    To obtain the fat mass, it will be necessary to previously measure the triceps, thigh and calf folds, and the waist, hip, relaxed arm, thigh and calf perimeters. For these previous measurements, two measurements will be taken in each subject, and a third measurement will be necessary if the difference between the first two is greater than 5%. Once the values of the previous measurements have been obtained, the fat mass can be calculated using the formula of Slaughter et al.

    Measured: Through study completion, an average of 1 year

  9. Anthropometric Variables (Fat-free mass)

    To obtain the fat-free mass, it will be necessary to previously measure the triceps, thigh and leg folds, and the perimeters of the waist, hip, relaxed arm, thigh and leg. For these previous measurements, two measurements will be taken in each subject, and a third measurement will be necessary if the difference between the first two is greater than 5%. Once the values of the previous measurements have been obtained, the-fat free mass can be calculated using the formula of Poortmans et al.

    Measured: Through study completion, an average of 1 year

  10. Anthropometric Variables (BMI)

    Previously obtained height and weight measurements will be used to establish the BMI. The formula used will be weight/height^2, and the result will be obtained in kg/m^2. This index is commonly used and is related to metabolic and cardiovascular diseases in adolescents and adults.

    Measured: Through study completion, an average of 1 year
