This study aimed to examine the effects of Ramadan on judokas’ performances in specific and non-specific tasks performed in the afternoon. Twelve male black belt judokas voluntarily participated in this study. The experimental design consisted of two testing phases: the fourth week of Ramadan (FWR) and five weeks after Ramadan (AR). At each phase, the judokas performed two test sessions. During the first one, they performed the squat jump (SJ), the countermovement jump (CMJ), and then, a maximal graded cycle test to assess maximal oxygen uptake (VO2max). During the second one, the judokas carried out a specific judo test. All tests were performed in the afternoon (i.e. 16:00 h). The results showed that jump heights measured in the SJ (p < 0.05) and the CMJ (p < 0.05) were significantly lower during the FWR than AR. Likewise, VO2max (p < 0.05) and peak heart rate recorded during the specific judo test (p < 0.001) were significantly higher AR with respect to the FWR. Moreover, the number of uchi-komi performed in the specific judo test was significantly lower during the FWR compared to AR (p < 0.001). In conclusion, the results of the present study demonstrate that Ramadan leads to impairment in judokas’ physical performances during generic and specific judo tests performed in the afternoon.

Calendário da FIJ

Como manter uma modalidade com caráter internacional, com uma grande concentração de competições na Europa e Ásia, um pouquinho nas Américas, duas na Oceania e nenhuma na África (excetuando o continental)? Deve estar reservada uma para a África (o Grand Slam a ser confirmado)...

Abstract

The aim of this study was firstly to investigate the correlation between bone parameters and grip strength (GS) in hands, explosive legs power (ELP), and hormonal parameters; second, to identify the most determinant variables of bone mineral density (BMD) among adolescent combat sport athletes. Fifty combat sport athletes aged 17.1±0.2yr were compared with 30 sedentary subjects matched for age, height, and pubertal stage. For all subjects, the BMD in deferent sites associated with anthropometric parameters were measured by dual-energy X-ray absorptiometry. The growth hormone (GH) and testosterone (TESTO) concentrations were tested. The GS in dominant (GSDA) and nondominant arms (GSNDA) and ELP were evaluated. All BMD measured were greater in athletes than in sedentary group (p<0 .01=".01" all="all" and="and" arms="arms" athletes="athletes" best="best" bmd="bmd" body="body" both="both" but="but" class="highlight" combat="combat" correlated="correlated" correlation="correlation" effect="effect" elp="elp" especially="especially" gh="gh" group="group" gs="gs" gsnda.="gsnda." gsnda="gsnda" has="has" height.="height." higher="higher" in="in" is="is" legs.="legs." measurements="measurements" nbsp="nbsp" of="of" only="only" osteogenic="osteogenic" p="p" practice="practice" predictor="predictor" proved="proved" sedentary="sedentary" showed="showed" significantly="significantly" sites="sites" span="span" spine="spine" sports="sports" study="study" style="border: 0px; font-size: 13px; font: inherit; margin: 0px; padding: 0px; vertical-align: baseline;" testo="testo" than="than" the="the" this="this" values="values" was="was" weight="weight" were="were" whole="whole" with="with" without="without">judo
