Background: Fundamental movement skills (FMS) have been identified as having a strong association with physical activity (PA). To develop FMS, resistance training (RT) may be a favourable intervention strategy. While PA guidelines recommend ‘activity to develop movement skills and muscular fitness’, there has been limited research to date on the impact of RT on FMS in youth. Purpose: This study aimed to explore the impact of a RT intervention on FMS of inactive and/or overweight/obese youth. Methods: Following ethics approval, 12 inactive and/or overweight/obese participants were assigned to an experimental (EG; age 8.7±1years, BMI z-score= 2.54±0.61) or control group (CG; age 9.2±1years, BMI z-score= 1.50±0.93). Pre- and post-intervention assessments for strength (isometric mid-thigh pull) and FMS (CAMSA) were completed. The EG participated in a 10-week RT programme (45minutes, twice weekly). Results: There were significant time x group interactions for FMS (CAMSA total P= 0.016, CAMSA skill score P= 0.036) with EG changes greater than CG. Large effect sizes were evident for CAMSA total score (Hedges’ g= 0.830, P= 0.138), CAMSA skill score (Hedges’ g= 0.895, P= 0.112) and relative strength (Hedges’ g= 0.825, P= 0.140). Conclusions: A RT intervention had a positive impact on strength and FMS in this population. Neural adaptations, resulting from RT, may provide a mechanism. Since there is strong evidence of an association between FMS and PA, it could be hypothesised that RT could positively affect PA levels too, however further work is required to substantiate this. Funding: None.
