Abstract

AIM:

The purpose of this study was to investigate the physiologic and performance changes with the addition of high-intensity interval training (HIIT) to a traditional judo programme.

METHODS:

Nine elite judokas (6 males and 3 females; age: 20±4 yrs; body mass: 69±2 kg; height: 172±7 cm; judo practice time: 13±6 yrs; weekly training volume: 13±5 hours, mean±SD) were recruited to perform a 12-week specific aerobic training program, which consisted of 2 session/week of 30-min continuous run at 60% at Vmax and one session/week of high-intensity interval training 15x1-min at 90% of Vmax with1 min of active recovery at 60% of Vmax. Before and after the intervention all athletes performed a graded maximal exercise test to measure maximal oxygen consumption ( max), ventilatory threshold (VT), maximal velocity (Vmax), heart rate (HR) and  off kinetics. and HR recovery kinetics were evaluated on a breath-by-breath basis using a single component exponential function. Anaerobic capacity during specific movements was assessed with the Special Judo Fitness Test (SJFT).

RESULTS:

The maximal speed reached during the maximal aerobic power test significantly increased (p=0.04), but VO2max did not change. τ of HR and of  recovery significantly decreased by 17.3% (p=0.04) and 22.0% (p<0.01), respectively. VT increased (6.6%; p=0.03) and the SJFT Index improved (p<0.001) 12% after training.

CONCLUSIONS:

The aerobic fitness of elite judokas may be improved by adding aerobic routines to the normal training enhancing the recovery capacity.

Abstract

Abstract The aim of this study was to define the time-motion (i.e., fighting, preparatory and breaking activity), technical (i.e., attack, timed-attack, counterattack, blocking and grasps) and tactical (i.e., upper limb, lower-limb, combination and throwing) profiles of the senior top-level karate competition played under the most recent rules of the International Karate Federation in relation to gender, match outcome and weight categories. Time-motion, tactical actions and technical executions were investigated of senior karatekas (n = 60) during the Karate World Championship. The referee's decisions caused an overall activity-to-break ratio of ~1:1.5 with a significant difference (P = 0.025) between karateka's weight categories (light = 1:1.5; middle = 1:2 and heavy = 1:1). High-intensity actions (i.e., attack and defensive actions performed quickly and powerfully) were higher in male compared to female athletes. Top-level karatekas used upper limb techniques more than lower limb ones, with both applied in the head more than in the body. For the high-intensity-actions to pause ratio and the percentage of combined techniques, light weight category was significantly higher than middle weight category. These findings suggest that training programs may need to be specific to the requirements of the gender and weight categories.

Boxing is one of the oldest combat sports. The aim of the current review is to critically analyze the amateur boxer’s physical and physiological characteristics and to provide practical recommendations for training as well as new areas of scientific research. High-level male and female boxers show a propensity for low body fat levels. Although studies on boxer somatotypes are limited, the available information shows that elite-level male boxers are characterized by a higher proportion of mesomorphy with a well-developed muscle mass and a low body fat level. To help support the overall metabolic demands of a boxing match and to accelerate the recovery process between rounds, athletes of both sexes require a high level of cardiorespiratory fitness. International boxers show a high peak and mean anaerobic power output. Muscle strength in both the upper and lower limbs is paramount for a fighter’s victory and is one of the keys to success in boxing. As boxing punches are brief actions and very dynamic, high-level boxing performance requires well-developed muscle power in both the upper and lower limbs. Albeit limited, the available studies reveal that isometric strength is linked to high-level boxing performance. Future investigations into the physical and physiological attributes of boxers are required to enrich the current data set and to help create a suitable training program.
