Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Before-school high-resistance circuit training group

Participants conducted circuit-based training before school at submaximal intensities (6, 7 and 8 RPE) with limited rest between exercises.

Group Type EXPERIMENTAL

Physical activity intervention using high-resistance circuit training.

Intervention Type OTHER

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.

Before-school strength training group

Participants conducted strength training before school at submaximal intensities (6, 7 and 8 RPE) with 1 min rest between exercises.

Group Type ACTIVE_COMPARATOR

Physical activity intervention using traditional strength training protocols

Intervention Type OTHER

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.

After-school high-resistance circuit training group

Participants conducted circuit-based training after school at submaximal intensities (6, 7 and 8 RPE) with limited rest between exercises.

Group Type EXPERIMENTAL

Physical activity intervention using high-resistance circuit training.

Intervention Type OTHER

An adapted version of Alcaraz's high-resistance circuit training (HRC) was utilized in the intervention.

After-school strength training group

Participants conducted strength training after school at submaximal intensities (6, 7 and 8 RPE) with 1 min rest between exercises.

Group Type ACTIVE_COMPARATOR

Strength training participants performed the 6 reps of the first exercise at the prescribed RPE and then rested for 1 minute.

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.
