Central nervous system

The central nervous system (CNS), which includes the brain and spinal cord, serves as the control center for nearly all movements, sensory perceptions, and bodily functions. Strength and endurance training are crucial because they send signals that activate the muscles and enable the coordination of complex movements. A well-trained CNS can activate muscle fibers faster, more precisely, and on a larger scale, directly enhancing strength, explosiveness, and precision.

High training intensities, complex compound exercises, or explosive movements such as those in power training place a heavy load on the CNS. If it becomes overloaded—due to overly frequent or intense training without sufficient recovery—central fatigue can occur. This manifests as reduced strength, slower reaction times, lower motivation, and increased susceptibility to injury.

Recovery for the CNS involves more than just resting the muscles; it also requires good-quality sleep, balanced nutrition, and active recovery. Mental stress also impacts the CNS and can reduce training performance. For long-term progress, it is essential to consciously manage training intensity, rest, and recovery to optimize the interaction between the nervous system and muscles.
