The Effect of High-Intensity Exercise on Changes of Blood Concentration Components in Algerian National Judo Athletes

Abstract

Summary The aim of the present study to verify the impact of judo competition on changes in the blood count of judo athletes during an official competition. Also to compare these results with the different weight category. Methods: fifteen youth trained athletes were included in the study were divided into three groups according to weight category (light, medial, and heavy) weight. All subjects performed a 5×4mn round of competition with 15mn of rest between rounds and Complete Blood Count (CBC) were collected before, immediately after the competition, Data are reported as mean and standard deviation. The Shapiro-Wilk test was performed to verify the normality of the data, and the significance level was set at P < 0.05. Blood sample count was tested by a paired Student’s t-test to compare the pre-test and post-test for the three groups. The results showed that blood cell count was significantly decreased immediately after judo competition (p < 0.05). However, red blood cell, White blood cell Blood platelets, Mean Cell Volume were significantly increased after the performance (p < 0.05). The current study showed that the judo competition (Rondori) effectively enhance some blood cell count; these changes are transient and probably due to the adaptation to efforts related to judo competition in highly-trained athletes.

Efficiency of Crossfit Exercises on The Level of Physical Fitness of Algerian High School Students

“…there are a considering changes in level indicators development of the maximum dynamic force of abdominal muscles the press, found mainly a significant improvement, both Men and women of the main groups, and these differences statistically significant (p <0,001). The above is confirmed by the data of [9; 13; 16], according to which it was found that during physical exertion, muscle hypertrophy occurs as a result of adaptivetrophic influence [7], which is characterized by an increase in thickness and denser packaging of contractile elements of muscle fiber. Thus, studies [24] indicate that the introduction of functional exercises in the main part of the lesson contributed to a significant improvement in strength abilities of high school students.…”

“…there are a considering changes in level indicators development of the maximum dynamic force of abdominal muscles the press, found mainly a significant improvement, both Men and women of the main groups, and these differences statistically significant (p <0.001). The above is confirmed by the data of (Adel et al, 2019;Mokhtar et al, 2019;Saddek et al, 2020), according to which it was found that during physical exertion, muscle hypertrophy occurs as a result of adaptive-trophic influence (Mukund & Subramaniam, 2020;Teplov, 1982), which is characterized by an increase in thickness and denser packaging of contractile elements of muscle fiber (Haun et al, 2019;Narici et al, 1996). Thus, studies (Annesi, Westcott, Faigenbaum, & Unruh, 2005;Belkadi et al, 2019;Krivoruchko et al, 2018;I.…”

“…However, according to the results of a number of authors (Adel, Alia, & Mohammed, 2020;Andrieieva et al, 2020;Bodnar & Andres, 2016;Krivoruchko et al, 2018;Palichuk et al, 2018;Prysiazhniuk et al, 2021;Sibley, 2012), currently operating lessons are ineffective, monotonous, do not sufficiently stimulate students to physical culture and sports activities. Therefore, this problem requires the search for new interesting forms, innovative means, methods and principles of system improvement physical education, increasing the volume and diversification of types of motor activity (Adel et al, 2019;Cacioppo et al, 2021;Petrova & Bala, 2020;Pricop, A. D., Pelin, R., Florescu, O., & Mezei, M. D., 2020;Voloshina et al, 2018). A number of scientists pay considerable attention to the issue optimization of the content of physical education lessons (I.…”

Characteristics of Handgrip (Kumi-Kata) Profile of Georgian Elite Judo Athletes

“…In possession of the data from the training and competition videos, it was possible to cross them to obtain a percentage quantification of the use of each type of handgrip, for each athlete, in the dominant and non-dominant hand. The analysis of the training videos was supervised by an expert (Adel et al, 2019) in affordance and hand-object interaction. To measure handgrip strength, two dynamometers were used, developed at the Instrumentation Laboratory (Adel et al, 2019).…”

To measure handgrip strength, two dynamometers were used, developed at the Instrumentation Laboratory (Adel et al, 2019). The measurement of the palm gripping force was performed by means of a "ring" load cell, and the gripper grip force by means of an "S" load cell.…”
