Answer:
True.
Explanation:
Stage 1 of NREM sleep is characterized by a low amplitude EEG, mixed frequency between range a and s (2 to 7Hz). EMG activity is usually higher than at other stages of sleep, but amplitude can vary widely. Stage 2 of NREM sleep is recognized by background activity and episodes of sleep spindles and K-complexes. Sleep spindles are short (12 to 14 Hz) waves that increase and decrease in amplitude to produce a spindle characteristic. Stage 3 NREM sleep is classified when slow waves or d waves (£ 2Hz) and high amplitude greater than 75mV (measured from lowest to highest wave - peak to peak) appear at 20 to 50% of the time of the day. record. Stage 4 NREM sleep is similar for EEG, EMG, and EOG from the previous stage; however, stage 4 is characterized by the presence of d waves in more than 50% of the time.
Accordingly, we can conclude that going through the NREM stages (1 to 4), the frequency of EEG waves decreases but their amplitude increases.
Answer:
The major glands of the endocrine system are the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body, and reproductive organs (ovaries and testes). The pancreas is also a part of this system; it has a role in hormone production as well as indigestion.
The Overload Principle is focused on sports fitness training.
It states that athletes must work harder than they usually workout as their bodies adjust themselves to higher workouts.
To safely apply Overload to your workout you should monitor the intensity of training as you increase it gradually and progressively.
You should choose and plan over one type of workout to apply Overload on it.
All other training activities should be coordinated and adjusted preventing other factors that influence overloading in duration and volume of training.

training is usually performed by seasoned or well-trained individuals because
of the high demand of speed and degrees of effort needed. Due to the nature of
alternating exercise activities within the program, it is preferred by some individuals because it is
fast and does not cause boredom. Beginners should not engage in this type of
training because of its explosive nature. Through rigorous and a
systematic training, beginners can eventually transition to this type of
exercise provided that they have been previously cleared because they have
already perfected and mastered the form of particular exercises.</span></span></span>
