Sedentary behavior in adults can negatively impacts one’s health, including functional ability. While training status (sedentary vs. resistance-trained) may influence anaerobic capacity and body composition, it is likely to also result in explosive performance differences. PURPOSE: The aim of the present study was to assess if functional performance differences (peak velocity, PV; peak power, PP; average velocity, AV; average power, AP; and vertical jump height, VJH) are observed between sedentary and resistance trained females during a countermovement vertical jump (CMJ). METHODS: Training status was defined as either, engaged in a structured weight training program that involved the lower body for a minimum of at least 6 months (resistance trained, RT) or, did not participate in any form of structured exercise (sedentary, SED). Participants included 20 SED (age = 21.25 ± 1.45 years, height 156.14 cm ± 33.74cm, mass 70.53kg ± 11.47kg) and 15 RT (age = 21.67 ± 0.94 years, height 165.23 cm ± 8.13 cm, mass 70.53kg ± 11.47kg) females. A jumping mat was used to measure vertical jump height, and a linear position transducer was used to assess power and velocity variables. During each CMJ, participants kept their hands on their hips, and feet were positioned shoulder-width apart. Independent sample T-Tests were used to evaluate the difference in PV, PP, AV, AP, and VJH between training status. An alpha of 0.05 was used for level of significance. RESULTS: No significant differences were found between PV (P=0.199), PP (P=0.826), AV (p=.788), AP (P=0.278), or VJH (P=0.797) between the two populations. CONCLUSION: The present study assessed CMJ performance between two different groups (resistance trained, and sedentary). The results revealed that there is no significant difference between sedentary and resistance trained females regarding PV, PP, AV, AP, and VJH.
