Treatments tested in this trial

Treatment groups
Trial outcomes
Primary outcomes
Physical activity and sedentary time
Physical activity and sedentary time will be measured by the Fitbit activity wristband version 6.0.
Secondary outcomes
Cardiorespiratory capacity
The 20-metres shuttle run test will be used to assess cardiorespiratory fitness. Participants will run the 20-metre distance to the rhythm of a recording. The initial speed is 8.5 km/h and will be increased by 0.5 km/h per section. The race will end when the participant stops due to fatigue or when he/she fails to cross the marked lines to the rhythm of the acoustic signals on two consecutive occasions. The last stage or half stage completed by the competitor will be scored.
Musculoskeletal capacity of Upper body
The hand grip test will be used to assess musculoskeletal capacity of upper body. The test shall be performed twice with each hand alternately. The maximum score of each hand in kilograms shall be recorded and the mean value between them shall be calculated.
Musculoskeletal capacity of lower body
Standing broad jump shall be used to assess the musculoskeletal capacity of the lower limbs. The participant shall stand behind a line with feet shoulder width apart. The participant is then asked to jump forward as far as possible with both feet. If he/she rests his/her hands or lifts his/her feet off the ground when landing, the test is invalid. The test shall be performed twice, and the best score recorded in centimetres.
Body mass index
Weight and height will be combined to report BMI in kg/m\^2.
