تأثير استخدام التدريب بالإيقاع الحركي البطيء لتمرينات مجموعة عضلات الظهر و الرجلين على المستوى الرقمي لرفعة (Dead Lift)‎ لرباعي منتخب مصر لرفع الأثقال المكفوفين

الملخص EN

This research aims for identifying the effect of type of different tempo speed into the program of preparing the Egyptian blind powerlifting team in preparation for the world championships in Georgia 2021, to develop the level of maximum strength for the team players and improve the digital level of the dead lift.

in light of this goal, the researcher used the experimental approach with an experimental design for one group that applied the program.

the study was conducted on the powerlifting team players, who consisted of 3 players for men, and the implementation of the program continued for a period of (10) weeks, with (10) training units per week.

the most important results of the study were the use of slow tempo exercises within the training program for the blind Egyptian national team players, which contributed to increasing the maximum strength variables for the back muscle group, and the percentage of improvement between the pre and post measurements of the back exercise was (9.58%).

contributed to an increase in the total of the three lifts with an improvement rate of (11.32%) between the tribal and remote measurements, in addition to the improvement in the relative strength of the lifters, as the improvement rate between the pre and post measurements reached (12.42%), all of which led to an improvement in the digital level of the dead lift where the percentage of improvement between the pre-and inter-measurement was (10.59%), between the inter-measurement and the post-measurement (0.35%), and between the pre-and post-measurement (10.20%).

Super slow tempo exercises have an important role in increasing muscle strength by raising neuromuscular efficiency and giving an appropriate opportunity for trainers to gradually increase the load.
