For the ischemic preconditioning (IPC) intervention, accuracy of protocol is paramount for mediating its possible ergogenic effects. However, lack standardization and widespread use arbitrary cuff pressures (ranging from 130 to >300 mmHg) have been predominantly observed, potentially affecting results compromising reproducibility findings. Thus, purpose this study was determine an appropriate pressure during IPC. Seventeen healthy male participants were enrolled in study. Anthropometric...

Purpose : To verify the effects of positive and negative verbal instructions regarding sham ischemic preconditioning (sham-IPC) on leg-extension resistance-exercise performance. Methods Thirty-five trained men were randomized to 1 3 groups: expectation, or control. Participants completed strength tests in 4 trials (2 familiarization, baseline, experimental). Experimental consisted participants’ receiving sham-IPC (3 × 5 cycles at only 20 mmHg). In positive- negative-expectation groups,...

Instagram (IG) reaches millions of people, sharing personal content and all kinds information, including those related to exercise health. However, the scientific quality posted information is questionable. Thus, this study aimed analyze whether health by popular Brazilian IG influencers has technical-scientific accuracy. A account was created identify profiles. The inclusion criteria accounts were: (1) having 50% shared posts topics about health, such as nutrition, wellness, medicine, or...

BACKGROUND: Previous studies have assessed the effects of ischemic preconditioning (IPC) on exercise performance and physiological variables, such as lactate muscle deoxygenation. In this study, we verified IPC heart rate during immediately after a maximal incremental cycling test (ICT).METHODS: Eighteen recreationally trained cyclists (28±4 years) were allocated to one three groups: IPC, SHAM Control. After first visit familiarization, attended laboratory two separate occasions perform an...

Several studies have reported that high doses of synthetic anabolic androgenic steroids (AAS) can serious negative effects on health, including the cardiovascular system. The aim this study was to evaluate combined AAS and exercise training ventricular repolarization cardiac autonomic modulation in rats. Male Wistar rats were allocated into 4 groups: sedentary treated with vehicle, nandrolone decanoate, swimming-trained decanoate. Ventricular evaluated by electrocardiographic analysis QT...

Was investigated ergogenic aids (EAs) used by Brazilian athletes and their association with performance, sex, sports classification, modality. It identified the main purposes of EAs prescription.239 15 modalities, ranging from regional to international level, answered a survey online.Highly competitive consumed nutritional mechanical more (OR = 1.96 CI 95% [1.28-2.9]; OR 1.79 [1.29-2.47]), while use psychological decreased [OR 1.66 (1.18-2.94); p 0.001]. Male 1.44 (1.11-2.88)] individual...

Aims: To evaluate whether body mass (BM) and composition may influence mountain bike cycling performance. Methods: Forty male amateur bikers attended the laboratory on two non-consecutive days. At first visit, anthropometric measures (height, BM, fat [BF], fat-free [FFM] index [BMI]) familiarization to incremental test were performed. On second cyclists performed again measure peak power output (PPO), relative BM (PPO-BM), time exhaustion (TE), which posteriorly correlated with measures....

Ischemic preconditioning (IPC) has been an excellent strategy for enhancing sports performance recovery, although there is still no consensus on the ideal protocol. Thus, this study aimed to evaluate effects of IPC with different cuff pressures (low pressure, medium and high pressure) attenuation neuromuscular fatigue after isometric test And verify whether improvement was related muscle oxygen saturation during Thirty males (18-35 years old) experience in resistance training were allocated...

Different competitive environments appears to affect the physical demands during sports competitions. Thus, aim of this study was report mechanical demand and pacing behaviour twelve male elite mountain bikers on cross-country short track (XCC) Olympic (XCO). During both competition, total race time, speed, power output (PO) cadence (CA) were recorded. As time in XCC is shorter (21.0 ± 0.5 vs 84.0 3.0 min; p<0.01), average speed (26.6 0.6 17.8 km/h; PO (365.0 26.7 301.0 26.2 watts;...

The complex process of hormonal release and interaction the Menstrual Cycle (MC) seems to impact athlete's physical psychological state. Objective: 1) investigate female athletes' understanding MC, including its various phases their potential effects on sports performance, 2) analyze self-perception performance during different MC 3) identify possible ergogenic strategies (nutritional, mechanical, pharmacological, and/or psychological) adopted by athletes for alleviating premenstrual...

Ischemic preconditioning (IPC) is a promising strategy to enhance athletic performance and recovery by improving local muscle oxygen saturation. This study aimed investigate the effects of different IPC protocols on oxygenation in physically active healthy men. Thirty-four subjects were randomized into three groups underwent four occlusion cycles duration (IPC-3), five (IPC-5) or seven (IPC-7) min only one limb. Near-infrared spectroscopy was used assess oxygenated deoxygenated hemoglobin...

Abstract Instagram (IG) reaches millions of people, sharing personal content, and also all kinds information, including those related to exercise health. However, scientific quality the posted information is questionable. Thus, this study aimed at analyzing whether health by main IG Brazilian influencers have technical-scientific accuracy. A account was created identify profiles. The inclusion criteria accounts were: 1) having 50% shared posts indeed topics about heath, such as nutrition,...

Abstract We investigated the potential for publication bias in field of sports science regarding studies on ergogenic aids and their effects exercise performance. found evidence to suggest that journals tend prioritize with positive results (76%) while neglecting those negative outcomes (2.7%). Worryingly, this could lead a discrepancy between reported conclusions actual study outcomes. also identified inconsistencies performance variable Taken together, these data highlight need future...
