Final answer:
Unilateral training in a strong athlete's program is likely to reduce bilateral asymmetries, correcting imbalances between the limbs. It can also serve as a diagnostic tool for identifying issues in the motor system, much like clinical strength tests used to detect upper motor neuron lesions.
Step-by-step explanation:
If a strong athlete incorporates only unilateral training into his or her program, the strength and conditioning professional might expect a reduction in bilateral asymmetries to occur. Unilateral training focuses on one side of the body at a time and can help to correct imbalances between limbs. When testing for muscle strength, pushing against resistance in a clinical setting can indicate differences in strength, signaling issues within the motor system or central nervous system. Exercises that evaluate this, such as the pronator drift test, help identify upper motor neuron (UMN) lesions, which may result from conditions like cerebral palsy, multiple sclerosis (MS), or stroke.
