Abstract
Background: This study compared a six-week triphasic resistance training (TRT) programmed with a matched-volume traditional resistance training (TRAD) protocol to examine changes in speed and explosive lower-limb power among collegiate football players.
Aim: To evaluate feasibility and performance outcomes between triphasic and traditional resistance training methods.
Methods: Eight male athletes (18–25 years) were randomly assigned to either group. Performance was assessed using the 10 m sprint, countermovement jump (CMJ), and Modified Illinois Change-of-Direction (MI-COD) tests. Feasibility metrics were also recorded.
Results: TRT showed greater improvements in CMJ (+5.4%), MI-COD (–3.9%), and sprint (–4.2%) compared with TRAD (<1%). Feasibility targets were fully achieved.
Conclusion: Triphasic resistance training produced larger improvements in speed, vertical jump, and change-of-direction ability compared with traditional training. The programmed was feasible, well tolerated, and safe for collegiate football players. A larger randomized trial is recommended to confirm these findings.
