The aim of this study was to determine the acute effects of a single session of resistance training on the functional and mechanical properties of leg muscles in recreationally active men. Eighteen subjects, with a mean age of 31 ± 4 years, with at least six months of continuous recreational activity and a frequency of 2–3 physical activities per week, participated in the study. All subjects performed a standardized squat session with external load, while four tests were used to assess neuromuscular performance: Countermovement Jump (CMJ), Squat Jump (SJ), Wall-sit test and Repeated Jump Test (RJT). The results showed a statistically significant decrease in performance in all tests after training (CMJ: -9.2%, SJ: -7.2%, Wall-sit: -18.1%, RJT: -10.4%; p < 0.001), indicating pronounced acute neuromuscular fatigue. The largest decreases were registered in isometric and reactive strength tests, while the decrease in explosive strength was also significant. The data obtained confirm that even a single session of resistance training can induce measurable, temporary changes in functional capacity of leg muscles, emphasizing the importance of adequate rest and training intensity planning. Future research could examine different training protocols, populations of different age groups, and recovery strategies to further investigate acute neuromuscular responses and optimize training planning in recreational and competitive athletes.
