Final answer:
a)true Persistent fatigue can be a result of overtraining, as seen in the case of Jasmin, a recreational runner experiencing extreme fatigue and other symptoms.
Step-by-step explanation:
Persistent fatigue can indeed be a result of overtraining. When an athlete, like Jasmin, experiences symptoms such as extreme fatigue, muscle cramps, spasms, heaviness in the legs, along with other issues like blurry vision and vomiting, it can be a clear indicator that the body is being pushed beyond its limits.
Muscle fatigue occurs when there is exhaustion of energy reserves and a buildup of lactic acid levels in the muscles. ATP is critical for normal muscle contraction, and as stores become depleted, performance declines. Resistance training or other strenuous activities can lead to overuse injuries.
If not performed correctly or if adequate rest is not provided between sessions.Ineffective training regimens, inadequate recovery, and poor nutrition can all contribute to overtraining syndrome. It is vital to balance exercise with proper rest and nutrients to prevent overtraining and the resulting fatigue or injuries.
