The study investigated the effect of a novel fatigue protocol (for fitness assessment) for contemporary dancers on physiological, psychological and stability indices. Nine dancers, Grade 5 or above, aged 18.8 years (14-27) and mean BMI 20.0 kg.m-2(15.8-22.6) wearing a heart rate monitor performed an incremental dance based fatigue protocol (that reflected performance intensity and movements) until reporting RPE16. Prior to and after the fatigue protocol dancers completed a Subjective Exercise Experience Scale and had their postural stability assessed using five trials of an arabesque performed on a forceplate. Mean exercise time to RPE16 was 15.7 min (10.5-19.0) and time to post fatigue protocol stability assessment was 1.1 min (0.8-1.2). A RM-ANOVA revealed there was a significance decrease (p<0.001) in percentage of predicted maximum heart rate between time of RPE16 (95.2 % HRmax, 89.7-100.5) and the time of the first post fatigue protocol arabesque (78.1 % HRmax, 69.1-88.3). Wilcoxon Signed-Rank Tests showed there was no signific.ant differences in the global measures of Positive Well Being (p = 0.53), Psychological Distress (p=1.0) and Fatigue (p=0.09). However, Tiredness (an item of the global measure Fatigue) significantly increased (p=0.04). A MANOVA showed there was no significant differences in the Standard Deviation of GRFant-post, GRFmed-lat, CoPant-post and CoPmed-lat (F= 1.87, p= 0.254) indicating there was no changes in postural stability. The results indicate that the fatigue protocol was unsuccessful in inducing fatigue despite dancers reporting an RPE 16.The rapid recovery observed prior to the collection of post fatigue protocol stability data may have negated dance based fatigue protocol effects.

The effect of dehydration on the athlete's kidney function M. Haji Rasouli* &A. Rohani* Azad University Of Islamshahr (Faculty Of Physical Education)
Introduction: Athletes who want to participate in a weight category less than their natural weight use always many methods. For example use of pruritic drugs of prohibition of water consumption. During the physical activity, athletes need to reduce the body temperature by evaporation of sweet. So water is an important substance for the care of athletes health during the games. Subjects were 24 Boxers (age = 22 ± 1.7 year) in all categories, that analyzed their urine's by Abrishami Medical lab. In Anzali City during the Iran Boxing champion ship - 2004, for calculation and determination of hematury, hemoglobinury, Bacterial in faction and another factors of kidneys function. The results showed: That 14 athletes have an or more symptoms of urinary system and kidney function deficiency. All results are shown Urinary PH (4), Protein (10), R.B.C (10), Haemoglobin (8), Cast (4), Bactery (7), Glocuse (1), Cristal (3). And indicate that weight lose by dehydration and water deficiency can cause the kidney disease and its very important an the health. Suggestion: To report this study with athlete in another sports and comparison the finding results according to kinds of sports and activity. Comparison of the results between athletes ((weight lose V.s non-weight lose)). Comparison of the results between athletes who consumption water efficiency V.s of the results deficiency before physical activity.
