# Enhancing Fundamental Movement Competency in Rural Middle School Children Through a Strength Training Intervention: A Feasibility Study

## TL;DR

This study tested a strength training program in a rural middle school and found it feasible, with students showing increased confidence in their abilities.

## Contribution

The study introduces a feasible strength training intervention for rural middle school children and explores coaching preferences.

## Key findings

- The Hoosier Strength intervention was highly feasible over four weeks and at follow-up.
- Participants' confidence in squatting was significantly predicted by their baseline squat knowledge.
- Students preferred coaches who emphasized teamwork and leadership over tactical analysis.

## Abstract

Background: Fundamental movement skills (FMS)—including muscular strength, endurance, and mobility—are linked to better health-related quality of life and higher physical activity in children. Rural children often score lower on FMS tests than urban peers due to resource limitations rather than ability. Thus, increasing access to FMS activities in under-resourced rural areas is essential. The primary objective was to test the feasibility of Hoosier Strength in a rural middle school sample, and the secondary objective was to observe the preliminary changes in FMS-related outcomes pre- to post-intervention and at follow-up. The exploratory objective was to explore how participants responded to different coaches on the Hoosier Strength coaching team (i.e., gender, coaching style during activities). Methods: This study used a Hybrid Type 3 design to evaluate feasibility and FMS outcomes, integrating qualitative and quantitative data. The four-week intervention included a test group (n = 24; 14 females, 10 males; mean age: females 12.4 ± 0.5 years, males 12.7 ± 0.4 years) and a control group (n = 12; 8 females, 4 males; mean age: females 12.9 ± 0.3 years, males 12.7 ± 0.3 years). Data analysis included descriptive statistics for feasibility indicators (Acceptability of Intervention Measures [AIM], Intervention Appropriateness Measure [IAM], and Feasibility of Intervention Measure [FIM]), linear regression for mobility and muscular endurance changes, t-tests for psychological need satisfaction and frustration, and regression analysis for squat knowledge and post-intervention confidence. Results: (1) There was high feasibility across the 4-week Hoosier Strength intervention and at follow-up; (2) there were no statistically significant changes in squat performance; (3) participants’ confidence in their ability to squat at the end of the intervention was significantly predicted by their squat knowledge at baseline; and (4) participants prioritized leadership and team management over tactical analysis, highlighting a preference for coaches who foster teamwork. Conclusions: The findings offer a transparent approach for evaluating the feasibility and preliminary outcomes of the Hoosier Strength intervention in an under-resourced rural middle school, thereby encouraging further investigation into strength training interventions in rural schools.
