Athletic Training Practice Exam

Which of the following is not considered a neural effect of resistance training?

1. Increased motor unit activation and recruitment

2. Increased discharge frequency of motoneurons

3. Increased muscle capillary density

4. Decreased neural inhibitions

The correct answer is: Increased muscle capillary density

Resistance training has a variety of effects on the neuromuscular system, particularly in how muscles are activated and controlled. The correct answer highlights that increased muscle capillary density is not a neural effect of resistance training. Instead, it pertains to the physiological adaptations of the muscle itself. When engaging in resistance training, one of the primary neural adaptations is the increased activation and recruitment of motor units, which are essential for muscle contraction. This means that the body becomes more efficient at activating the muscle fibers necessary for lifting weights or performing resistance exercises. Furthermore, resistance training also leads to an increased discharge frequency of motoneurons. This means that the nerves that send signals to the muscles are firing more frequently, which enhances muscle contraction strength and efficiency during exercise. Decreased neural inhibitions refer to a reduction in the body's natural protective mechanisms that prevent excessive force production. By overcoming these inhibitions, individuals can lift heavier weights as they train, further enhancing strength and muscular control. In contrast, increased muscle capillary density relates more to the vascular adaptations of the muscle tissue that improve blood flow and oxygen delivery. This adaptation primarily supports endurance and recovery rather than directly influencing neural processes involved in strength training. Therefore, it stands out as the option that does not describe a neural
