“…Although previous studies have pointed out the negative effect of rapid weight loss on mood [37,38], in the present study there was no difference in humor profile components (tension, depression, anger, vigour, fatigue and confusion) between the weighing and one hour pre-match moments.…”

SummaryIntroduction. The aim of this study was to analyze the magnitude and methods of weight loss among MMA fighters and the influence of this practice in hydration and profile of mood state.Material and methods. The sample was composed by eight MMA fighters during a professional MMA competition, but only five athletes finished all procedures. To evaluate the weight loss prevalence, magnitude and methods it was applied the Rapid Weight Loss Questionnaire adapted to MMA. Saliva samples were taken in the official weigh-in and one hour before of the combats to estimate the salivary osmolality. To evaluate the profile of mood states the Brunel Mood Scale (BRUMS) was applied.Results. The results showed that all participants already had lost weight to take part in another event. The athletes reported that they always adopted as method to lose weight: to make more exercise (50 %) and reduce food intake of liquids (37.5 %). The dangers methods to health were cited by athletes in the following sequence: use of diuretics (37.5%), sauna (37.5%), training intentionally in heated training rooms (50 %) and use of diet pills (12.5%). In the competition analyzed 88% of athletes reduced their body mass (4.5 ± 4.2 kg, 5.4 ± 4.3 %) to compete. The salivary osmolality did not show significant difference between weighin (55.6 ± 30.7 mOsmol/kg H2O) and pre-match moment (40.2 ± 27.9 mOsmol/kg H2O). The profile of mood states did not change between the weigh-in (tension: 1.2 ± 1.8, depression: 0 ± 0, anger: 1.2 ± 1.6, vigour: 14.0 ± 0.7, fatigue: 2.6 ± 5.3, confusion: 0.2 ± 0.4) and the pre-match moment (tension: 2.6 ± 2.2, depression: 0 ± 0, anger: 1.4 ± 1.9, vigour: 15.6 ± 0.5, fatigue: 0.0, confusion: 2.8 ± 3.9).Conclusions. The conclusion is that there is a great prevalence of weight loss in MMA athletes in this sample. Furthermore, dangers methods to health are or were practiced to reduce the body mass to compete.

“…A previous investigation found a positive correlation between the dehydration level and cortisol concentration, whereas a negative correlation was observed between dehydration and total testosterone [7]. Filaire et al [8] observed impairments in performance, differences in the nutritional state (proteins and macronutrients), and increased aggressiveness after the rWL procedure. Malnutrition leads to body weight loss, since it reduces the glycogen stores, and may prejudice the performance [26], mainly in high intensity efforts, commonly associated with attack and defence actions in judo.…”

“…Many strategies have been performed to achieve this goal, such as increasing exercise, restricting food and liquids and using plastic suits [5,6]. Nonetheless, some methods can be harmful to the athletes' health, mainly those associated with severe food and liquid restrictions [7,8]. It was reported that high levels of dehydration and heat stress caused by rWL in the pre-competitive period had led to the deaths of three adolescent wrestlers [9].…”

Purpose. The study aimed to analyse the methods and magnitudes of rapid weight loss (rWL) in judo team members in distinct periods before the biggest state competition in Southern Brazil. Methods. Twelve male judo athletes took part in the study. The data collection was performed in three periods: (1) three months before the biggest state competition, (2) one week before the competition, (3) the day prior to the event. Anthropometric assessment and the rapid Weight Loss Questionnaire were performed. Student's t-test and ANOVA were applied, with the significance level set at p < 0.05. Results. The main results showed that the majority of athletes reduced 7.1 ± 6.8 kg and started to lose weight to compete 13-16 years earlier. Increasing exercises (91.7%) and restricting fluid intake (41.7%) were the most frequent methods of weight loss. The judo coach/sensei was the person who most influenced the rWL procedure (58.3%). The athletes reduced 5% of their body weight (p < 0.01), 2.4% of their body fat (p < 0.01), and 2% of their fat-free mass (p = 0.04). Conclusions. We conclude that rWL was a common and premature practice in the athletes in the study. The most common methods were increasing exercise volume and restricting fluid and food intake. The coach/sensei was the most influential person in this practice. The judo athletes presented decreases in body fat and fat-free mass during the period prior to the competition.

“…Judokas spend significantly high amount of energy during the training and competitions which affects energy balance, hormonal profile and metabolic hemostasis (Filaire et al, 2001). There was a limited number of studies related females judokas in the literature (Prouteau et al, 2007).…”

The purpose of this study is to investigate the effects of four weeks judo training on plasma leptin levels. Twenty-five female national team athletes with a mean age of 18.12±1.12 years; body weight of 62.72±22.72 kg; body height of 164.28±7.28 cm, BMI of 23.17±6.28 kg/m 2 ; training experience of 6.56±5.44 years participated in this study. The data were collected from junior female judokas who trained six times in a week for two hours daily. Physical measurements and blood samples were taken before and after four weeks of training including technical, tactical and physical preparations. Body fat percentages were measured by using the Tanita Bioimpedance BC-418 (Tokio, Japan). Statistical Package for Social Science 15.0 (SPSS) was used to analyse the obtained results. Before and after the training, paired samples t-test was used to evaluate the differences between serum leptine and body fat percentages. Results of this study showed that pre-training serum leptin levels were significantly lower than post-training levels (p<0.01). There was also significant decrease in body fat percentages after four week training (p<0.01). Four weeks judo training results in a decrease in total body fat and serum leptin level in junior female judokas. It may be considered that lowered serum leptin levels were due to the decrease of the body fat percentage after four weeks training.
