Plain English Summary

Background and study aims
This study plans to evaluate the effects of a 10-week FIT FIRST Teen (FFT) intervention on blood pressure, physical fitness and body composition of Danish adolescents aged 12-15 years old. The 10-week FFT training is expected to have beneficial effects on resting heart rate for Danish 12-15-year-olds, calling for further development and long-term evaluation of the program.

Who can participate?
Danish pupils aged 12 to 17 years old in 6th to 9th grade from 15 municipal schools

What does the study involve?
Participants will be randomly allocated to an intervention group or a usual practice control group. The FFT group will complete three weekly 40-minute FFT sessions with modified, motivating, involving, high-intensity sports-based activities. Before and after the 10-week intervention, resting heart rate and blood pressure, body composition (InBody270), postural balance, standing long jump and performance on the Yo-Yo intermittent recovery level 1 children’s test (YYIR1C) will be measured.

What are the possible benefits and risks of participating?
The possible benefits are a better health profile and there are no risks of participating.

Where is the study run from?
University of Southern Denmark

When is the study starting and how long is it expected to run for?
August 2021 to December 2022

Who is funding the study?
1. Ole Kirk's Foundation
2. Novo Nordisk Foundation

Study acronymFIT FIRST TEEN
Study hypothesisFrequent intense training in schools for teenagers will improve their physical health status
Ethics approval(s)Ethics approval not required
Ethics approval additional information17/08/2021: The Scientific Ethics Committee 2 for Region Southern Denmark confirmed that the project is not subject to notification to the committee system, as the project does not fall within the definition of a health science research project; ref: 21/43086
ConditionPrevention of lifestyle diseases
InterventionRandomization will be performed on a school level by picking notes with school names from a bowl. Pupils will be randomly allocated to either the intervention group or a usual practice control group. The intervention uses a specific sports training concept (FIT FIRST), which the teachers in the school deliver 3 x 40 minutes per week for 10 weeks.
Intervention typeBehavioural
Primary outcome measureCardiorespiratory fitness measured using the Yoyo test at baseline and after 10 weeks
Secondary outcome measuresThe following secondary outcome measures will be assessed at baseline and after 10 weeks:
1. Body composition measured using bioimpedance (InBody 270)
2. Resting heart rate and blood pressure measured using the Oscillometric method
3. Balance measured using the stork balance test
4. Muscle strength measured using the standing long jump test
