Final answer:
Linear periodization is a training approach where intensity increases while volume decreases over time, typically used to build strength. On the other hand, undulating periodization involves frequent changes in workout intensity and volume to aid in recovery and prevent overtraining. The variability in weight loss outcomes can be due to individual differences, not just the training program.
Step-by-step explanation:
During linear periodization, there is a gradual and consistent increase in the intensity of exercise while the volume tends to decrease over time.
This method is often used to build strength and muscle over a set period, with the athlete reaching peak performance at the end of the cycle.
In contrast, undulating periodization involves frequent changes in the intensity and volume of workouts. Instead of progressing linearly, the athlete will experience variations in training stimuli, which can be daily or weekly.
This method is believed to aid in recovery and reduce the risk of overtraining while still promoting gains in strength and performance.
The differences in outcomes regarding the amount of weight lost among people who perform the same workout can be attributed to individual variability.
Factors such as genetics, diet, sleep, stress, and metabolism can all cause people to respond differently to the same exercise program.
