54
How does disrupted neural transmission limit exercise?
It alters signals to and from muscles, negatively affecting coordination and strength.
55

Disrupted brain activity refers to impaired brain function
56
: How does disrupted brain activity limit exercise?
: It reduces the desire to continue exercise and the muscular coordination required to maintain exercise.
57
What is fatigue?
Fatigue refers to the inability to maintain a task, caused by various factors like intensity and duration of exercise. It can be physical or mental and is often temporary.
58
What is overtraining?
: Overtraining is characterized by physiological maladaptations and performance decrements when the body fails to adapt to the training stimulus. It leads to chronic fatigue and can result in a decline in performance.
59
What is overreaching?
Overreaching is when training intensity is temporarily increased, which can be helpful for performance improvement, provided there is adequate recovery. It can lead to short-term fatigue but is usually recoverable.
60
What is overtraining?
Overtraining is characterized by chronic fatigue that could take months to recover from. It results from excessive training without sufficient recovery, leading to a significant decline in performance and prolonged recovery.
61
: Why is periodic fatigue beneficial for training?
Periodic fatigue is beneficial because it maximizes intracellular signals required to promote physiological adaptations, such as muscle growth and improved performance.
62
What is the risk of fatigue occurring too often in training?
: Fatigue occurring too often puts the athlete at risk for overtraining, leading to chronic fatigue and decreased performance.
63
Why is reducing training stress important after an intense workout?
Reducing training stress allows time for adaptations to occur, as improvements take time and recovery is necessary for optimal performance gains.
64
What factors are important for optimal adaptations to training?
Optimal sleep, hydration, and nutrition are essential for maximizing the adaptations to training.
65
what are the training types associated with fatigue and adaptations?
Moderate-intensity continuous training (MICT) and high-intensity interval training (HIIT/SIT) are training types that influence fatigue and adaptations.
