Abstract EN

The study aimed to identify the effect of daily dynamic rhythm on physiological and fitness level in female short distance runners at Yarmouk university.

the researchers used the comparative causal method to achieve the study objectives.

the study was applied on a sample of (16) short distance athletes runners at Yarmouk university.

physiological and physical variables were measured in two different periods (morning and evening) of a time interval for (3) days.

the physiological measurements included aspartate transaminase (AST), alanine transaminase (alt), Gamma Glutamyl Tran peptidase (GAMMA GT), lactate dehydrogenase(LDH), creatinine cayenne's (CK), thyrotropin stimulating hormone(TSH), tertionethione(t3), cortisol, heart rate pulse(HRP) ,systolic blood pressure(SBP) and diastolic blood pressure (DBP).

the fitness measurements included set up, push up, flexibility trunk, long jump from stability and speed.

the results showed that there was a difference in the thyrotropin stimulating hormone (TSH) between the two periods, as the values were (16.61 ml in the morning and 9.47 ml in the evening) and showed that there were differences in the value of systolic blood (93.43 mmhg in the morning, 112mmhg in the evening), and showed that there were differences in the value of diastolic blood pressure and their values (62 mmhg in the morning vs 72 mmhg in the evening).

the results also showed that there were differences in the set up test between the two times (evening and morning periods) as the test values were (47.57 repetitions/ min in the morning and 36.86 repetitions/ min in the evening) and difference in the push up test as the test values were (35.57 repetitions in the morning and26.86 repetitions in the evening).

in the flexibility test the values were (20.86 cm in the morning and 16.00 cm in the evening), and showed significant difference in speed test values (6.18 asecond in the morning, 7.47 a second in the evening).

while the result did not indicate a statistically different in other indicators (muscle fatigue variables, cortisol, tropodotronin, heart rate pulse, and jump test) between the morning and evening periods.

the researchers recommended to pay attention to times of ideal measurement to test physiological and physical levels of the players.
