The purpose of the present study was to investigate the effect of a resistance training program on improving functional performance, gait speed, and static and dynamic balance in an individual with multiple sclerosis. The study involved a 35-year-old male diagnosed with the relapsing-remitting form of the disease. The training protocol focused on developing muscle strength through resistance exercises, with particular emphasis on strengthening the lower limbs and core musculature. Progressive loading was implemented throughout the intervention, reaching approximately 80% of 1RM towards the end of the training period. Each training session lasted 50 minutes and included a 5-minute warm-up, 40 minutes of resistance exercises, and a 5-minute cool-down. The weekly training load was scheduled across two sessions, taking into account the participant’s daily routine. Balance (dynamic and static) was assessed using the Berg Balance Scale (BBS) test, functional capacity using the Timed Up and Go test, and gait parameters using Gait Analysis in the Biomechanics Laboratory of the Department of Physical Education and Sport Science, as well as dynamic and static balance. Additionally, the participant’s anthropometric characteristics were recorded, along with the perceived exertion index using the Borg CR–10 scale, which was completed after each session. The results revealed significant improvement in dynamic balance (BBS) and functional capacity (TUG). Despite a technical issue in collecting the dynamic and static balance and gait measurements through Gait - Analysis, notable improvements were observed. Body weight decreased, accompanied by a reduction in muscle mass, possibly due to insufficient energy intake during a period of potential overtraining or a change in daily routine combined with reduced caloric intake despite increased physical exercise. Furthermore, subjective fatigue scores indicated rapid adaptation to the program, with the fatigue index decreasing to 6. Overall, the findings suggest that resistance training applying progressive loading up to 80% of one-repetition maximum (1RM) can enhance functional capacity, balance, and psychosocial well-being in individuals with Multiple Sclerosis. The findings underscore the need for longer-duration interventions to collect more data and facilitate the adaptation of individuals with Multiple Sclerosis to resistance-based training programs.
