The effect of liquid losses in trainings during competition period on some biochemical values of u18 male judokas ( age 15-17)

Abstract

Purpose:The purpose of this study is to investigate the effect of liquid losses occurring in training sessions during the competition period on some biochemical values of the male Judokas competing in the U18 category. Material:The values of the 17 male athletes, who were included in the national team at least once, were checked in our study which compares the values of athletes before the competition and immediately after the competition. Urine Density, Urine pH, BUN, Creatine and Potassium values from the biochemistry values were measured besides the age, height and weight of the athletes participating in the study. Results:As a result of the measurements made; it was found that the kg pre-test averages of the participant athletes were 67,82 ±17,87, post-test averages were 64,88±16,89, Urine Density pre-test averages were 1.017,94 ±7,08, posttest averages were 1.025±8,48, Urine pH pre-test averages were 6,15±0,70, post-test averages were 5,82±0,50, BUN pre-test averages were 15,65±3,14, post-test averages were 24,35±3,60, Creatine pre-test averages were 0,48±0,20, post-test averages were 0,93±0,41, K Potassium pre-test averages were 4,16±0,35, post-test averages were 4,95 ±0,64. As a result of the statistical analysis, although there was no significant difference in urine pH pretest and post-test values, statistically significant difference was found between pre-test and post-test values in other selected parameters (p <0,05). Conclusions:As a result; it is thought that in our country in which the adjustment of the weight class is made unconsciously and unplanned, this will lead to the health problems of the athletes in many ways, especially in the later ages. Particularly in the professional sense, the health problems, which athletes who enter weight competitions and who enter at least 10 international competitions in the Olympic sense for the Judo branch a year can experience in the later ages as a result of such exhaustion, should be well considered. The the significant differences in studies in the literature and in our work also indicate that acute and rapid dehydration causes athletes to be harmed in terms of health and leads to the loss of performance. The result of our study is that the athletes should be prompted for weight control in a planned way to prevent the adjusting weight by acute and excessive dehydration.

Acceptance of the sense of implementing safe fall programs for people with visual impairments or after amputation of limbs - the perspective of modern adapted physical activity

“…No matter that e.g. judo training, stimulates muscle strength, endurance and other motor abilities [42][43][44][45]. As a sport, judo entails high risk of injuries and even death [46,47].…”

Effects of caloric restriction on anthropometrical and specific performance in highly-trained university judo athletes

“…We hypothesized that the Weight loss would result in more detrimental effects on both caloric restriction and judo performance test. [16] investigate the effect of liquid losses occurring in training sessions during the competition period on some biochemical values of the male Judokas competing in the U18 category. The results of the performance tests support the fact that the duration of the intervention was important for changes in performance test.…”

“…The loss of large amounts of body mass in a short time is extremely harmful to the body; it can reduce muscle strength [14] also demonstrate that the exercise-induced hyperthermia and dehydration in the present experiments had only minor effects on the neuromuscular performance. In addition, reductions in renal blood fluid and the volume of liquid filtered by the kidneys [15,16].Additionally, these physiological alterations can decrease anaerobic capacity, an important determinant of overall performance in judo [17]. A questionnaire was designed to evaluate rapid Weight loss patterns of competitive judo players and to assess its validity and reliability [18].…”

Contest coefficients of the elite judo athletes of Russia and Kyrgyzstan (less than 60 kg, 66 kg, 73 kg and 81 kg) from 2010 till 2015

“…According to G. Lech, the excessive development of the muscular strength of the judoists will create certain difficulties in the development of the technique and tactical skill of the athletes [17]. It should be noted the weight loss factor before the competition [18]. The rapid weight loss has a negative impact primarily on the muscle strength of the athletes [19].…”
