What does the “F.S” in the benefits of muscle conditioning refer to?

The "F.S" in the benefits of muscle conditioning specifically refers to the "Fibre size of muscles." This is an essential concept in strength training and muscle conditioning because it highlights how training can lead to hypertrophy, which is the increase in the size of muscle fibers.

When individuals engage in resistance training or muscle conditioning exercises, they create micro-tears in the muscle fibers. As these fibers repair, they grow back larger and stronger, which leads to a greater overall muscle mass. This increase in fibre size is beneficial not only for enhancing strength and power but also for improving overall metabolic rate and body composition.

Understanding fibre size helps fitness instructors design appropriate conditioning programs tailored to individual fitness goals, whether that is to gain muscle mass, improve athletic performance, or enhance functional fitness for daily activities. The focus on fibre size is crucial in emphasizing the role that muscle conditioning plays in overall physical development and longevity.
