Final answer:
The type of periodization featuring great variation with each microcycle is b) Undulating periodization. This style involves changing the training variables frequently to create a pattern of varied muscular work. Differences in weight loss outcomes among individuals in the same program are attributed to biological variability.
Step-by-step explanation:
Type of Periodization in Fitness Training
Regarding the type of periodization that includes great variation with each microcycle, typically exemplified by 4-5 distinct workouts, the correct answer is b) Undulating periodization. Undulating periodization involves frequent changes in the training variables, such as intensity, volume, and exercise selection within a microcycle. This method is designed to provide a pattern of physical exercise that alternates between short periods of vigorous muscular work and longer periods of medium (and varied) muscular work.
The differences in outcomes, such as weight lost by individuals in a workout program, may be attributed to biological variability. Biological variability refers to the different responses of individuals due to a variety of factors, including genetic makeup, diet, sleep patterns, stress levels, and prior fitness levels. Hence, even when 20 people follow the same workout program with identical exercise regimens, the results can significantly vary due to individual differences.
