Abstract
This study examined the individual and combined effects of plyometric
and circuit training on body mass index (BMI), resting heart rate (RHR), and
maximal oxygen uptake (VO₂ Max) in adolescent athletes. A total of 120 athletes
aged 16–18 years were randomly assigned to plyometric, circuit, combined
plyometric–circuit, and control groups (n = 30 each). The experimental groups
trained three times per week for two weeks, while the control group maintained
regular sports practice. BMI, RHR, and VO₂ Max were assessed before and after
the intervention using standardized anthropometric, physiological, and aerobic
testing protocols. Analysis of covariance (ANCOVA), controlling for pre-test
scores, revealed significant group effects for BMI (p < .001, η² = .275),
RHR (p = .019, η² = .088), and VO₂ Max (p = .001, η² = .291). Post hoc
comparisons showed that combined training resulted in the greatest reduction in
BMI, significantly outperforming plyometric, circuit, and control groups.
Plyometric training produced the largest reduction in RHR compared to combined
training, indicating enhanced cardiovascular efficiency. Circuit and combined
training led to greater VO₂ Max improvements than plyometric training, with the
combined group showing a slight, non-significant advantage. These results
highlight that training modality selection should align with specific
physiological goals—combined training is most effective for improving body
composition and aerobic capacity, while plyometric training is optimal for
lowering resting heart rate. The findings provide evidence-based guidance for
designing targeted, age-appropriate conditioning programs to enhance health and
performance in adolescent athletes.
