This study aimed at examining the effects of nine weeks of sand-based plyometric-jump training (PJT) combined with endurance running on either outdoor or treadmill surface on measures of physical fitness. Male participants (age, 20.1 ± 1.7 years) were randomly assigned to a sand-based PJT combined with endurance running on outdoor surface (OT, n = 25) or treadmill surface (TT, n = 25). The endurance running intervention comprised a mixed training method, i.e., long slow distance, tempo, and interval running drills. A control group was additionally included in this study (CG, n = 25). Participants in CG followed their regular physical activity as OT and TT but did not receive any specific intervention. Individuals were assessed for their 50-m linear sprint time, standing long jump (SLJ) distance, cardiorespiratory fitness (i.e., Cooper test), forced vital capacity (FVC), calf girth, and resting heart rate (RHR). A three (groups: OT, TT, CG) by two (time: pre, post) ANOVA for repeated measures was used to analyze the exercise-specific effects. In case of significant group-by-time interactions, Bonferroni adjusted paired (within-group) and independent (between-group comparisons at post) t-tests were used for post-hoc analyses. Significant group-by-time interactions were found for all dependent variables ( p &lt; 0.001 - 0.002, ɳ p  2 = 0.16 - 0.78). Group-specific post-hoc tests showed improvements for all variables after OT ( p &lt; 0.001, Hedges'g effect size [ g ] = 0.05 - 1.94) and TT ( p &lt; 0.001, g = 0.04 - 2.73), but not in the CG ( p = 0.058 - 1.000, g = 0.00 - 0.34). Compared to CG, OT showed larger SLJ (p = 0.001), cardiorespiratory fitness ( p = 0.004), FVC ( p = 0.008), and RHR ( p &lt; 0.001) improvements. TT showed larger improvements in SLJ ( p = 0.036), cardiorespiratory fitness ( p &lt; 0.001), and RHR ( p &lt; 0.001) compared with CG. Compared to OT, TT showed larger improvements for SLJ ( p = 0.018). In conclusion, sand-based PJT combined with either OT or TT similarly improved most measures of physical fitness, with greater SLJ improvement after TT. Coaches may use both concurrent exercise regimes based on preferences and logistical constrains (e.g., weather; access to treadmill equipment).
