Summary

Adolescents may have limited time to engage in physical activity during the school day prompting investigations of before and after-school times along with time efficient programming. High-resistance circuit training has been used as a time effective protocol, however adolescents have yet to be studied. The primary aim was to assess feasibility (recruitment, sample size, consent rate, retention rate, fidelity, attendance, adverse events, and participant experience) of a high-resistance circuit training or strength training intervention, conducted before or after-school. The second aim was to explore changes in body composition, strength, and aerobic fitness. Researchers compared feasibility outcomes as well as participant experience between time frames and treatment group.

Interventions

Type	Name	Description
OTHER	Physical activity intervention using traditional strength training protocols	Strength training participants performed the 6 reps of the first exercise at the prescribed RPE and then rested for 1 minute. Participants then completed another set of their first exercise with the required rest until the prescribed sets were completed. Participants performed the second and third exercises in the same fashion. Once the first block was completed, participants rested 5 min, then completed the second block. Six exercises were completed.
OTHER	Physical activity intervention using high-resistance circuit training.	An adapted version of Alcaraz's high-resistance circuit training (HRC) was utilized in the intervention. Exercises and intensities used by strength training was the same for HRC except HRC participants performed the first three exercises as a circuit with 35 seconds rest between exercises, then completed the second block of exercises in the same fashion.
