Strength in Numbers: A classroom based resistance training and mathematics intervention

1. Brief name: Strength in Numbers 2. What materials: The materials for the Strength in Numbers program include a series of eight 5-minute videos, designed to be delivered at the beginning of each mathematics lesson. These videos will integrate resistance training exercises with mathematics content, providing short, focused movement breaks that align with the curriculum. 3. What procedures: Access to the Intervention videos will be available to classroom teachers via email after the completion of baseline measures. Teachers will then deliver the video intervention at the beginning of the lesson to their Stage 5 mathematics class on two occasions throughout the week. The procedure that will be followed in the classroom is that teachers will: - Allow students to enter the classroom with your regular procedure - Ask students to place their bag away from their chair or under their desk - No equipment, especially laptops should be removed from the student’s bag. - Students stand behind their desk, with their chair behind them. - Once all students are ready, play the Strength in Numbers video. The video lasts 5 minutes. During the video could you please encourage participation and ensure students perform exercises safely within their own desk area. You may also participate as this often encourages class participation. - Record each completed session to monitor adherence to the program. 4. Who provided: The materials for the Strength in Numbers program are provided online as a video to increase consistency across classes. Each classroom teacher will play the video, and they are encouraged to use suggested strategies to promote student participation. The video prescribes body weight exercises such as lunges, chair tricep dips and isometric contractions. 5. How: Stage 5 Mathematics classes occur 2-3 times per week. Teachers can select the most suitable lessons to deliver the intervention but this must occur at least twice during the week. 6. Where: Participants will complete the intervention while at their own desk in the mathematics classroom. 7. When and how much: The Strength in Numbers videos are 5 minutes long. They are designed using a Tabata protocol (20 seconds exercising and 10 seconds break, Total = 4 minutes). At the completion of the exercise there is 1 minute to complete a numeracy question, relating to the topic as a class. The video will be delivered 2 x per week for 4 weeks (Total sessions = 8). The intensity of the sessions are designed to be moderate. 8. Tailoring: All participants will take part in the Strength in Numbers program. The introduction video advises students to modify exercises if they can't do them because of an injury or their surroundings. For example, if someone has an arm injury, they can do squats instead of chair tricep dips. Each exercise has different difficulty levels, and participants are encouraged to try the highest level they feel comfortable with.
