Effectiveness of Ischemia and Hyperemia exercises for upper limb on lactic and pH levels and their relation to Horizontal kinetic energy and record achievement level of swimmers022meterscrawl stroke

The current research aims to identify the following:
1- Effectiveness of ischemia and hyperthermia exercises of the upper limb on the lactic levels of the swimmer 200 meters crawl stroke (at research) .
2- Effectiveness of ischemia and hyperthermia exercises of the upper limb on the pH of the swimmer 200 meters crawl stroke (at research) 
3- the correlation of the effectiveness of ischemia and Hyperemia exercises of the upper limb of both levels of lactic and pH of a side and horizontal kinetic energy and the level of record achievement of swimmers 200 meters crawl stroke (atresearch) on the other side .
Research Questions: To achieve the research objectives, the researcher impose the following hypotheses :
1- Are there statistical differences at the level of 0.05 between the tribal and post-tribal measurements in the levels of lactic, pH, Horizontal kinetic energy and the record achievement of the experimental group? In what direction, if any, of tribal or post-tribal measures?
2- Are there statistical differences at the level of 0.05 between the tribal and post-tribal measurements in the levels of lactic, pH, Horizontal kinetic energy and the record achievement of the control group? In what direction, if any, of tribal or post-tribal measures?
3- Are there statistically significant differences at the 0.05 level between the mean of the post-tribal measures in the levels of lactic, pH, Horizontal kinetic energy, and record achievement levels of the experimental and control groups? And which direction, if any?
4- Are there a percentage improvement and Modfiedblaks gain ratio between the two measures of the experimental and control groups in the lactic, pH, horizontal kinetic energy and record achievement levels of swimmers200meters crawl stroke (at study)? And for which groups, if any?
5- Is there a correlation between the levels of lactic and pH (at study) of the experimental group (the research sample) on the one side? And between the horizontal kinetic energy and the level of record achievement of swimmers 200 meters crawl stroke (research sample) on the other side? What if it exists?
