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.

En el presente trabajo me centraré en el estudio, desde la posición procesal del deudor demandado, de algunas de las cuestiones más polémicas que tienen lugar en los procedimientos monitorios y en los procedimientos declarativos subsiguientes relativos a la reclamación de saldo de tarjetas de crédito revolving: los documentos requeridos para la admisión a trámite del procedimiento monitorio, el control de oficio de cláusulas abusivas, la omisión de pronunciamiento sobre la excepción de nulidad causada por la usura, la sujeción de las cláusulas contractuales al control de transparencia y los efectos restitutorios de la declaración de nulidad contractual.
This study compared the acute neuromuscular responses to two resistance training loading scheme: a heavy-load, low-volume scheme [4 sets of 4 repetitions; 85% one-repetition maximum (1RM), 150-s rest; HL] and a moderate-load, high-volume scheme [4 sets of 10 repetitions, 70% 1RM, 90-s rest; ML]. Sixteen resistance-trained men completed HL and ML sessions on a leg-press machine with the left lower limb. Maximal voluntary contraction (MVC) force, and the peak force, rate of force development (RFD) of a triplet (3 electrical stimuli of femoral nerve stimulation; 100 Hz) were measured before and immediately after each session. Maximal M wave and motor-evoked potential (MEP) areas, silent-period duration (SP), short-interval intracortical inhibition (SICI) and tissue oxygenation index (TOI) were also measured on the left vastus lateralis. TOI decreased only during ML (p<0.003). Reductions in MVC force, triplet force and RFD were greater after ML than HL (p0.05). The results suggest that the acute neuromuscular responses to the two loading schemes differ primarily at the peripheral level. This may help practitioners to optimize exercise prescription by anticipating the magnitude and physiological origin of the acute post-exercise impairments.
