This study investigated the prevalence, magnitude, and methods of rap-id weight loss among male female Taekwondo athletes from all competitive levels. A questionnaire was administered to 72 men (regional/state level, n=31; national/international n=41) 44 women n=9; national/international, n=35). Among athletes, 77.4% regional/state level 75.6% declared have reduced compete in lighter categories. women, 88.9% 88.6% reported use rapid strategies. Athletes usually lose ~3% their body weight,...
Objectives The aim of this study was to evaluate the effect caffeine ingestion on performance and estimated energy system contribution during simulated taekwondo combat post-exercise parasympathetic reactivation. Methods Ten athletes completed two experimental sessions separated by at least 48 hours. Athletes consumed a capsule containing either (5 mg∙kg-1) or placebo (cellulose) one hour before simulation (3 rounds 2 min 1 passive recovery), in double-blind, randomized, repeated-measures...
Abstract Purpose : To investigate the effect of sodium bicarbonate (NaHCO 3 ) on performance and estimated energy system contribution during simulated taekwondo combat. Methods Nine athletes completed two experimental sessions separated by at least 48 h. Athletes consumed 300 mg/kg body mass NaHCO or placebo (CaCO 90 min before combat simulation (three rounds 2 1 passive recovery), in a double‐blind, randomized, repeated‐measures crossover design. All was filmed to quantify time spent...
This study compared the acute effect of strength, plyometric, and complex exercises (combined strength plyometric exercise) in countermovement jump (CMJ) frequency speed kick test (FSKT) attempted to establish best rest interval maximize performance CMJ, number kicks, impact generated during FSKT. Eleven taekwondo athletes (mean ± SD; age: 20.3 5.2 years; body mass: 71.8 15.3 kg; height: 177 7.2 cm) participated. One control 9 experimental conditions were randomly applied. Each condition was...
Santos, JFS and Franchini, E. Frequency speed of kick test performance comparison between female taekwondo athletes different competitive levels. J Strength Cond Res 32(10): 2934-2938, 2018-Construct validity is a desirable characteristic in any to differentiate athletes. However, no taekwondo-specific was investigated with this purpose. The purpose study compare grouped Forty-two divided into International/National (median [interquartile range]; n = 21, age: 20 [18-25] years; body mass: 60...
The aim of this study was to assess the effects different postactivation potentiation conditioning activities’ volumes and intensities on countermovement jump multiple sets high speed kicks. Nine taekwondo athletes (M±SD; age: 20.3±5.2 years; height: 177±7.2 cm; body mass: 71.8±15.3 kg; maximum dynamic half-squat 1RM: 132.8±32.5 kg practice time: 9.6±7.2 years) participated. One control four experimental conditions were randomly applied. Each condition composed warm-up, activity (half-squat:...
Objectives The present study aimed to evaluate the effects of using hyperbaric oxygen therapy during post-training recovery in jiu-jitsu athletes. Methods Eleven experienced Brazilian athletes were investigated and following two training sessions 1h30min. Using a cross-over design, randomly assigned passive for 2 hours or (OHB) same duration. After 7-day period, interventions reversed. Before, immediately after, post 24 hours, blood samples collected examine hormone concentrations (cortisol...
In combat sports, the specificity of training requires that athlete improve all performance indicators associated with match. For this reason, muscle power seems to be determinant during application techniques result in scores, specifically punches, kicks, elbows, knees, throwing techniques, transitions groundwork and some sometimes, win match by knockout. Based these information’s, present chapter will approach items referring manifestation monitoring, prescription exercises for grappling,...
Specific training methods is an important aspect in the preparation of taekwondo athletes. The purpose this study was to investigate effect a short-duration high-intensity interval (HIIT) program with specific techniques on anaerobic performance. Twelve athletes were randomized into control (n=6) or experimental groups (n=6). protocol consisted 3 blocks 6 sets 10s all-out effort, passive recovery between and 1-min rest blocks, conducted days per week during 4-weeks. A three-way analysis...
The aim of this study was to evaluate if caffeine can reduce the negative influence diurnal variations on repeated-sprint performance, in addition investigating afternoon would potentiate performance compared with morning. Thirteen physically active men took part randomized, double-blind, placebo-controlled and crossover study. All participants underwent a ability test (10 × 6 s cycle sprints, 30 rest) at 60 min after ingestion either 5 mg·kg −1 or placebo under 4 different conditions:...
Recently, the Frequency Speed of Kick Test (FSKT10s) and its intermittent version (5 x 10s/10s intervals, FSKTmult) have been used to assess physical fitness taekwondo athletes, but no classificatory normative table was found for these tests. Thus, aim study present two tables both FSKT10s FSKTmult male female athletes. One hundred fifteen athletes (median [interquartile range] age: 20 [17;27] years; body height: 175 [170;182] cm; mass: 67 [60;78] kg; experience time: 6 [3;10] years) seventy...
Propagandas eleitorais são parte essencial de uma eleição. A popularização das redes sociais online ofereceu um meio promissor para que candidatos se comuniquem com o eleitorado em larga escala. De fato, já foi apontado uso destas aplicações divulgar propagandas eleitorais, inclusive fora do período permitido pela legislação brasileira (propagandas antecipadas). Porém, combate desta prática é frustrado ausência conhecimento mais amplo características deste tipo conteúdo, permitindo soluções...
