The purpose of this study was to determine the relationship between attack time (AT) and skipping (ST) during 2007 Taekwondo World Championship 2008 Beijing Olympic Games. A total 22 matches (65 rounds, 13 semifinals, 8 finals) from 23 (63 rounds with 16 athletes each 1 quarterfinal round) Games, both in male category, were assessed using time-motion analysis. AT considered as which athlete attacked or tried attack, whereas ST without attempting attack. ratio ∼ 1:7 based on data pooled 2...
The aim of this study was to investigate the effects caffeine on reaction time during a specific taekwondo task and athletic performance simulated contest. Ten athletes ingested either 5 mg·kg−1 body mass or placebo performed two combats (spaced apart by 20 min). reaction-time test (five kicks “Bandal Tchagui”) immediately prior first combat after second combats. Caffeine improved (from 0.42 ± 0.05 0.37 0.07 s) only (P = 0.004). During combat, break times rounds were shorter in ingestion,...
The aim of this study was to determine the effect time day on performance, pacing, and hormonal metabolic responses during a 1000-m cycling time-trial. Nine male, recreational cyclists visited laboratory four times. During 1st visit participants performed an incremental test 2nd they familiarization trial. On 3rd 4th visits, TT at either 8 am or 6 pm, in randomized, repeated-measures, crossover design. complete trial lower evening than morning (88.2±8.7 versus 94.7±10.9 s, respectively,...
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes novel disease 2019 (COVID-19), has been responsible for a large global outbreak. The latest number of confirmed cases COVID-19 is >4.6 million globally, including >315,000 deaths, and obliging >4 billion people to stay confined their homes [1]. Most with experience mild moderate illness, but around 15% progress severe pneumonia, about 5% distress syndrome. maintenance social distancing, frequent hand-washing,...
This study examined potential sex differences on performance and perceived fatigability during a whole-body endurance exercise performed under normoxia or moderate hypoxia. Nine male eight female cyclists 4-km cycling time-trial hypoxia conditions. Performance its central peripheral determinants were measured via pre- to post-exercise changes in maximal voluntary isometric contraction (IMVC), activation (VA), potentiated twitch force (TwPt) of knee extensors, respectively. Perceived was...
The objective of this study was to propose an alternative method (MAODALT) estimate the maximal accumulated oxygen deficit (MAOD) using only one supramaximal exhaustive test. Nine participants performed following tests: (a) a incremental exercise test, (b) six submaximal constant workload tests, and (c) Traditional MAOD determined by calculating difference between predicted O2 demand uptake during MAODALT established summing fast component excess post-exercise consumption equivalent for...
The combined supplementation of caffeine (CAF) and sodium bicarbonate (NaHCO 3 ) may have a potential ergogenic effect during intermittent-exercise tasks such as judo; however, its in this sport has not been tested. Purpose: To investigate the isolated effects CAF NaHCO on judo performance. Methods: Ten judokas performed 4 protocols—NaHCO , CAF, + placebo (PLA) (cellulose)—followed by Special Judo Fitness Tests (SJFTs) interspaced with 5 min rest. Results: In first SJFT, supplement CAF)...
The purpose of the present study was to investigate effects caffeine ingestion on pacing strategy and energy expenditure during a 4000-m cycling time-trial (TT). Eight recreationally-trained male cyclists volunteered performed maximal incremental test familiarization their first second visits, respectively. On third fourth participants TT after ingesting capsules containing either (5 mg.kg(-1) body weight, CAF) or cellulose (PLA). tests were applied in double-blind, randomized,...
Background: Aerobic exercise is recommended to improve health. However, the increased ventilation might increase doses of inhaled air pollutants, negating health benefits in highly polluted areas. Our objective was estimate dose pollutants during two simulated sessions at cleanest and dirtiest cities reported by World Health Organization (WHO) considering quality. Methods: Minute data were extracted from laboratory-based 116 incremental running tests used calculate total a hypothetical...
Purpose The aim of the current study is to describe functionality free software developed for energy system contributions and expenditure calculation during exercise, namely GEDAE-LaB. Methods Eleven participants performed following tests: 1) a maximal cycling incremental test measure ventilatory threshold oxygen uptake (O2max); 2) workload constant at moderate domain (90% threshold); 3) severe (110% O2max). Oxygen plasma lactate were measured tests. aerobic (AMET), anaerobic lactic (LAMET),...
The link between total work performed above critical power (CP) and peripheral muscle fatigue during self-paced exercise is unknown. We investigated the influence of caffeine on done CP a 4-km cycling time trial (TT) subsequent consequence development central fatigue. Nine cyclists three constant-load trials to determine two TTs ~75 min after oral (5 mg/kg) or cellulose (placebo) ingestion. Neuromuscular functions were assessed before 50 supplementation 1 TT. Oral alone had no effect...
Abstract Endurance exercise begun with reduced muscle glycogen stores seems to potentiate skeletal protein abundance and gene expression. However, it is unknown whether this greater signaling responses due performing two sessions in close proximity—as a first session necessary reduce the stores. In present study, we manipulated recovery duration between glycogen‐depleting second session, such that started both approaches but was performed either 2 or 15 hours after (so‐called “twice‐a‐day”...
Physical exercise protects against the development of cardiovascular disease, partly by lowering plasmatic total cholesterol, LDL-cholesterol and increased HDL-cholesterol levels. In addition, it is now established that reduction adiponectin C-reactive protein (CRP) plasminogen activator inhibitor-1 (PAI-1) levels play a role in maintenance an inflammatory state disease. This study aimed to examine plasma lipid profile markers individual with sedentary lifestyle and/or highly trained...
Abstract This study determined which peripheral variables would better predict the rating of perceived exertion (RPE) and time to exhaustion (TE) during exercise at different intensities. Ten men performed exercises first lactate threshold (LT1), second (LT2), 50% distance from LT1 LT2 (TT ), 25% maximal power output (TW ). Lactate, catecholamines, potassium, pH, glucose, V̇O 2 , VE, HR, respiratory rate (RR) RPE were measured plotted against duration for slope calculation. Glucose,...
The purpose this study was to examine the effects of caffeine ingestion on performance and energy expenditure (anaerobic aerobic contribution) during a 4-km cycling time trial (TT) performed after carbohydrate (CHO) availability-lowering exercise protocol. After preliminary familiarization trials, seven amateur cyclists three TT in double-blind, randomized crossover design. trials were either no previous (CON), or CHO protocol (DEP) evening, followed by placebo (DEP-PLA) 5 mg.kg−1 intake...
Abstract In recent years, there have been an increasing number of genetic variants associated with athletic phenotypes. Here, we selected a set sports‐relevant polymorphisms that previously suggested as markers for human physical performance, and examined their association status in large cohort Brazilians. We evaluated sample 1,622 individuals, which 966 were nonathletes, 656 athletes: 328 endurance athletes power athletes. Only the AGT M268T minor allele was nominally status. Conversely,...
This study investigated the effect of caffeine on neuromuscular function, power and sprint performance during days following an eccentric-based exercise. Using a randomly counterbalanced, crossover double-blinded design, eleven male jumpers sprinters (age: 18.7 ± 2.7 years) performed half-squat exercise (4 x 12 repetitions at 70% 1 RM), with eccentric action emphasized by using flexible strip attached to their knees (Tirante Musculador®). They ingested either capsule placebo or (5 mg.kg-1...
