Background: High levels of physical activity often lead to muscle fatigue and injury, making massage therapy a preferred alternative treatment. Many therapists work in non-ergonomic conditions, which can lead to muscle fatigue. This study evaluates the impact of massage duration on therapist muscle fatigue to improve well-being and service quality. Methods: The study involved 6 student therapists from FPOK UPI, measured using surface electromyography (sEMG), blood lactate, and handgrip dynamometer at the 0th, 16th, and 32nd minutes. Results: The data from this study do not provide sufficient evidence to prove that massage duration significantly affects sEMG in the right and left arms (p-value > 0.05). However, massage duration significantly influences the increase in blood lactate levels (p-value 0.000), particularly between 0 and 16 minutes and between 0 and 32 minutes. Massage duration also affects arm power, especially in right and left handgrip endurance and left handgrip strength (p-value 0.000), with significant differences in some time variables. Conclusion: The data from this study do not provide sufficient evidence to prove that massage duration significantly impacts muscle fatigue in FPOK UPI student therapists, as analyzed using muscle electrical signals, blood lactate, and arm power (p-value MANOVA Pillai’s Trace 0.147, Wilks’Lambda 0.054).
