“…Ozkan and Ibrahim [30] also measured alterations to CK levels as a consequence of weight reduction, reporting results similar to those of Isik et al [29]. Ten wrestlers lost > 5% of their body weight by undergoing dehydration as their RWL method.…”

Objective: To observe the effect of rapid weight loss (RWL) methods over 3 days on muscle damage in judokas. Methods: Eighteen judokas participated in this crossover study, meaning that judo athletes were subjected to exercise-only phase (4 days) and RWL phase (3 days). Subjects were tested for myoglobin, creatine kinase, aldolase, hemoglobin, and hematocrit values on seven consecutive days. These biomarkers served as indicators of acute muscle damage. Results: During the exercise-only phase, no significant changes were observed. Myoglobin (Mb) (p < 0.001), creatine kinase (CK) (p < 0.001) and aldolase (ALD) (p < 0.001) significantly increased only during the RWL phase, as well as hemoglobin (Hb) (p < 0.001) and hematocrit (Hct) (p < 0.005) values. It was detected that peak values for muscle damage biomarkers were reached on the sixth day, while Hct and Hb values were the highest on the seventh day of the study. Conclusion: Our study showed significant muscle damage induced by RWL. The prevalence of RWL use by judokas is high but firm scientific evidence is lacking in the evaluation of the current practice of it. Therefore, further knowledge must be gained to evaluate the effectiveness of RWL on performance and its impact on judokas' wellbeing.

“…Further studies should elaborate how different methods may lead to different levels of muscle damage, as suggested by those studies that focused on body weight loss due to dehydration methods [29,30]. Based on our data, we are unable to confirm the degree to which RWL caused MD and to what degree exercise contributed to it.…”

“…It is well documented that athletes perform better than untrained; especially in the specific sport they compete in [27][28][29]. In addition, athletes, as well as other trained populations, present with faster and more efficient recovery from physical activity [30][31].…”

Purpose: To investigate the influence of the WAnT on blood pressure, lactate, and NTproBNP in trained Wrestlers and untrained young males.Methods: 20 males (n=20), ages 18-25 underwent the WAnT. The study included 2 groups. Group 1 included 10 untrained individuals, and group 2 included 10 wrestlers. NTproBNP (ng/mL), lactate (mmol/ L), and blood pressure (mmHg) were measured at rest, immediate-post, two minutes post, and ten minutes post. The mechanical outputs (W) calculated for each subject. NTproBNP was analyzed utilizing ELIZA.Results: The wrestler's resting NTproBNP levels were higher (35.5 ± 7.59 vs. 35.15 ± 4.82 accordingly), with non-significant differences between the groups. Immediate Post NTproBNP was higher for wrestlers (40.25 ± 14.08 vs. 37.33 ± 9.94) with a positive and strong correlation between PP and IP NTproBNP (r = 0.85). While the untrained had a substantially higher post 10 NTproBNP (45.07 ± 11.75 vs. 32 ± 5.57), both group's NTproBNP was elevated post 10 minutes with a significant difference from post 2 minutes values (p=0.035). PP was significantly higher for the wrestlers (1031.6 ± 188.65 vs. 960.91 ± 189.01). No significant differences were found between groups for RPP and RMP. Conclusions:NTproBNP values were within the ranges reported in the literature. The WAnT did not put any of the subjects at risk due to cardiac stress. The recovery dynamics regarding NTproBNP were different between groups. Wrestlers recovered rapidly with a slight elevation 10 minutes post-test, while the untrained recovered slowly with a significant elevation of NTproBNP 10 minutes post-test.

“…It is difficult to discourage athletes from these practices, but they can be made aware, if there is evidence that such practices could affect their muscular functioning [3]. To explain this muscular damage, studies have been carried out on elite fighters and in healthy elite and amateur athletes who were evaluated after intensive exercise until muscular exhaustion, causing an elevation of cardiac biomarkers in 62% of the subjects like troponin, a possible indicator of heart damage, acute coronary syndrome, or even infarction [4][5][6][7][8][9][10][11]. Wrestlers were divided into groups, depending on their hydration levels, and it was concluded that the levels of inflammation and markers of muscle damage (creatine phosphokinase, CPK, lactate dehydrogenase, LDH, and aspartate transaminase, AST) obtained in their post-competition blood samples were different between both groups and higher in the forearm muscles of the dehydrated group.…”

Combat sports have a great interest in society and among professional sports. They are an important group of sports in the Olympic Games, but the strategies carried out by athletes to reduce body weight for weighing day, is famously known, suffering the adverse physical and psychological effects of rapid weight loss. This could compromise not only the performance, but the health and development of young athletes. A total of 22 elite male judokas (18.05 ± 1.05 years old) were evaluated during four different competitions in one season; the variables of body weight, water levels, and lean and fat mass were measured by bioimpedance (BIA), (Tanita BC545N) during one season. Using the linear mixed model test, we found significant differences in bodyweight variable during the competitions 3–4. The water level variable showed significant differences in all competitions, except for 2–4. Body mass index was significantly different in all competitions, being higher in the later competitions, except between competitions 1–2 and 2–3. Judokas participate in weight loss methods for their weigh-in days. Furthermore, the age at which the athletes reduced their water levels are worrisome. These results could be used to create healthy programs, especially in elite judokas, in order to carry out strategies before, during, and after competitions with weight loss and controlled water levels increasing future performance and health.
