maintained at a high level in sleep-deprived subjects.

Unnecessary Expletives (exp)
1. It is my goal in this paper to argue that vitamin C enhances immune function.
2. There are several mechanisms that could have accounted for the greater weight loss in subjects on the
Atkins diet.
3. There has been found to be some protection against bone loss in women who take hormone
replacement therapy.

Wordiness (wordy)
1. I conclude that altitude training is not beneficial due to the fact that its adaptations are only temporary.
2. What is classified by the term secondary amenorrhea is described by the absence of menstrual cycles in
women who have previously had their periods.
3. In a study done by Loucks et al. (1999), monkeys were used to study the effects of endurance training

Noun-pronoun Disagreement (n-p agree)
1. To develop cardiovascular endurance an individual should exercise at 70-80% of their VO2max.

demineralization.

Non-specific "This's" (ref)
1. Acidosis, or a decrease in body pH, may reduce an individual's exercise capacity. This may have a
direct effect on weight control.
2. The results of the study indicated that mean power, time to peak power, and peak power remained
unaffected. One reason for this might be that the dose of creatine was too low.
3. This paper addresses several factors that influence the ergogenic properties of caffeine and how this
relates to performance.

Problematic Tense Shifts (tense shift)
1. The Atkins subjects experienced a decrease in exercise capacity due to dehydration. It is also possible
that the subjects will lose muscle mass, which also limits exercise capacity.
2. The subjects on the Atkins diet experienced a significant increase in exercise capacity over the last two
weeks of the study. Based on this result and an understanding of the physiological mechanisms of ketosis,
I conclude that the Atkins diet enhances exercise capacity.
Lack of Parallel Structure (parallel)
1. Studies show that exercise capacity is impaired for subjects on low-carbohydrate diets compared to a
high-carbohydrate diet.
2. Physical therapists often cite the following reasons for avoiding iontophoresis in their treatments: 1)
skin burns, 2) individual responses may vary, and 3) an uncomfortable tingling and burning sensation.

and it is possible for massage to improve flexibility.
4. Research on altitude training has been conducted on distance running, track athletes, and cross-country
skiers.
5. If our subjects' glycogen stores were already low before they began to exercise, then they were not
going to be able to utilize glycogen for energy very much longer and thereby decreasing their exercise
capacity.

Inappropriate Word Choice (wc)

2. Some doctors do not prescribe sleeping pills, as patients can become addicted to these drugs.
3. Subjects who slept at least eight hours a night made significantly less errors on the vigilance task.

Excessive Separation of Subjects and Their Verbs (svs, LNS)

in subjects who were deprived of sleep, indicated in the results showing that vigilance deteriorated over
the 48 hours of testing agree with those from previous studies.

2. A serious sleep disorder is narcolepsy which is characterized by 5- to 30-minute sleep attacks during
the day.
3. Stage 1 sleep is characterized by normal muscle tone and vivid dreams do not tend to occur during this
stage.
4. Several studies have been conducted on the effects of sleep loss on cognitive performance, the findings
from these studies conflict.

antigens; thus failing to support the hypothesis that sleep deprivation impairs immune function.
2. Previous studies on the effects of sleep on immune function have been flawed for the following
reasons; inconsistent methods for depriving animals of sleep, imprecise measures of antibody activity,
and poor controls for stress responses that are not due to sleep deprivation..

high-frequency, low-amplitude brain waves; and paralysis of the skeletal muscles.
