Abstract
The effect of rationing of rests among of exercises by guide of indicator of lactic acid in achievement of efficiency 800 Meter for youthThis thesis aim to know the indicator of lactic acid in the blood that affect by the training loads for efficiency 800 Meter , and knowing on the used rests after physical effort , and rationing of rests among of exercises by guide of indicator of lactic acid before and after any physical effort 236 مجلة كلیة التربیة الریاضیة للبنات المجلد 14 ملحق العدد 2 عام 2015 The researcher imagines being differences has statistics guide at results of indicator of lactic acid between pre-post of two tests, and being differences has statistics guide at results of indicator of lactic acid and achievement . The researcher deal with theoretical studies that was included the researches about this subject as rest , and its notion, notion of lactic acid in the blood , as well as efficiency 800 meter , for subject of this research . the researcher used the experiential method by style of one group for suitable with type of research . The group of research was specified by player of youth team for Athletics for year (2014-2015) as (6) players . The sample was chosen by the willfulness method from group of origin as (3) players . the period is (120 weeks , as (2) units at week . The total of units of training methods as (24) units . The suitable statistics procedures were used to reach for the results , after that the results and its analyses and discussion were showed . The researcher reach to important conclusions at light of research result such as : 1- There is a clear improve in focus of lactic in the blood of sample from rationing rest . 2- Improve of achievement resulted effect of rests rationing that was dependent during the main trial so the rationing rests has positive on the results of research sample . In the light of this the researcher recommend for following recommendation such as : 1- Using the rationing rests at the exercises of short distances . 2- Making a similar studies for small or big ages at efficiency 800 Meter. 3-Making a similar studies for small or big ages at efficiency for long or short distances .
