Final answer:
NMES is beneficial for increasing muscular strength but cannot replace the need for sport-specific training, nor can it improve coordination, technique, or game strategy, which are essential for athletic performance.
Step-by-step explanation:
NMES, or Neuromuscular Electrical Stimulation, is a method used to induce muscular contractions using electrical impulses. While NMES can be effective in enhancing strength, particularly in sports that demand high levels of muscular power, it is not designed to replace sport-specific training. Moreover, NMES cannot address deficits such as coordination, technique, or game strategy, which are critical elements for success in any sport. Athletes using NMES should still rely on conventional training to improve upon these aspects.
