Objective: To examine the effectiveness of exercises for improving forearm bone mass.\ud Data Sources: MEDLINE, EMBASE, CINAHL, AMED, Web of Science, and Cochrane CENTRAL were searched from their inception until\ud December 2018.\ud Study Selection: Eligibility included adults undertaking upper limb exercise interventions (�12wk) to improve bone mass.\ud Data Extraction: Screening of titles, abstracts, and full texts and data extraction were undertaken independently by pairs of reviewers. Included\ud studies were quality appraised using Cochrane risk of bias tool.\ud Data Synthesis: Exercise interventions were classified into “resistance training” of high or low intensity (HIRT/LIRT, respectively) or “impact.”\ud Random-effects meta-analysis of the percentage change in forearm bone mass from baseline was conducted. Twenty-six studies were included in\ud the review, of which 21 provided suitable data for meta-analysis. Methodological quality ranged from “low” to “unclear” risk of bias. Exercise\ud generally led to increases (moderate-quality evidence) in forearm bone mass (standard mean difference [SMD], 1.27; 95% CI, 0.66-1.88; overall\ud effect Z valueZ4.10; P
