Primary purpose: OTHER

Brief 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.


Eligibility criteria: Inclusion Criteria:

* Untrained
* Male and female

Exclusion Criteria:

* Recent injuries or medical conditions that may influence high-intensity performance
* Currently enrolled in another training program including resistance, cardiovascular, or sports-based program
* Uninsured participants
* Drastically altering diet
* Use of performance-enhancing substances (i.e., creatine, pre-workout, post-workout supplements).
