Abstract
Introduction: Mental fatigue is defined as body or soul
tiredness which can be caused by stress, overwork, excessive use of drugs or
physical or mental illnesses. Fatigue is one of the reasons of productivity
loss as well as occurring accidents. Therefore, mental fatigue measurement is
of great importance. This study was aimed to determine the consistency of
mental fatigue measurement by self-reported VAS and the flicker fusion
apparatus.
Material and Methods: A descriptive study was conducted on 30 students.
After they had accomplished mental tasks (i.e. mathematical problem solving and
responding to MMPI questionnaire), mental fatigued was measured by
self-reported VAS and flicker fusion apparatus. To analyze the results, paired
sample T-test and Spearman correlation test were applied in SPSS software
version 11.5 (P<0.05).
Findings: The results of mental fatigue measurements by
both methods of self-reported VAS and the flicker fusion apparatus showed
significant increase in mental fatigue after finishing each of the mental
tasks. But the findings revealed no consistency between the two methods.
Conclusion: Since
self-reported VAS is a subjective technique, it seems that the lack of
consistency between the two methods is due to its inefficiency in the mental
fatigue measurement. Therefore, further studies with more precise methods such
as EEG is suggested.

Abstract
Background: The purpose of present study was to evaluate the effects of six- week aerobic step training on cardiovascular fitness, body composition, flexibility, leg anaerobic power and quality of life of isfahan university female students in academic year 2012-2011. Methods: 31 female students of Isfahan university were randomly assigned in experimental group (N=16, mean Age 27±2 , Weight 58.34 ±6.27, Height 1.61±4) and control group (N=15, mean Age25 ±1 , Weight 54.7±7.32, Height 1.61±6).pre test and post test measurements included cardiovascular fitness, body composition, flexibility, leg anaerobic power and quality of life questionnaire(WHOQOL(. analysis of covariance( ANCOVA) was used to test to effects of aerobic training as intervention(P<0.05). Results: There was a significant increase in cardiovascular fitness (p=0.001) and there was a significant decrease in body composition (p=0.046). There was no significant increase in flexibility (p=0.109) and leg anaerobic power (p=0.180). there was a significant increase in total score of quality of life(p=0.00). Conclusion: a six- week aerobic step training improves quality of life and cardiovascular fitness and body composition of training group
