Heart Rate Recovery (HRR%) Variation by Position and Measurement Time After Imitation Sparring in Male Jiu-Jitsu Trainees with White Belt
Abstrct
This study measured the physiological response caused by the attack and defence of the top and bottom positions in the Jiu-jitsu game with heart rate to investigate the recovery trend between each position using heart rate recovery (%). The subjects of this study were eight white belt men with more than one year of training experience in the adult division of the Jujitsu competition (from 19 to 29 years). Four teams, each consisting of two people, were selected and experimented by cross-allocation. The sparring was performed in three rounds of five minutes, assuming the competition and the rest time was applied the same as the sparring time. Each position's heart rate recovery rate (%) measurement was based on the heart rate level just before each round. The heart rate of thirty seconds, one, two, three, four, and five minutes immediately after each round (sparring) was measured and expressed in %. The results are as follows: First, the heart rate level immediately after sparring between positions showed a high heart rate level in the bottom position immediately after all rounds (sparring). Second, it was found that the bottom position performed exercise under higher physiological conditions than the top position, and the heart rate recovery tended to rapidly decrease in the bottom position at the same rest time. Third, resting heart rate appears to predict heart rate recovery.

The advent of cinema brought with it its use as a propaganda device with which to transmit ideals and doctrines. As a result, newsreels and cinema documentaries were born with the aim of showing the «most relevant» news of the country and abroad, the former with a shorter duration. In this study, the Spanish NO-DO and «Sucesos Argentinos» are used as primary sources to interpret the images and imaginaries that were projected between 1943 and 1955 on female physical culture. The intention is to understand the official discourse of both political regimes on what Argentinean and Spanish society should be like, especially by questioning those meanings about women. In total, 69 issues of NO-DO and 14 editions of «Sucesos Argentinos» have been found which aim to show female physical culture in this period. The female physical culture shown in both newsreels was aimed at strengthening women’s bodies so that they could carry out their «natural functions» (mother, wife, housewife), as well as highlighting their «inferiority» in relation to men through lower impact activities and the homogenization of bodies through clothing, and the performance of the same exercises in synchrony. And all this in countries with different regimes, but which, in the end, coincided.
