The aim of this study was to assess the validity (Study 1) and reliability 2) a novel intermittent running test (Carminatti's test) for physiological assessment soccer players. In Study 1, 28 players performed Carminatti's test, repeated sprint ability an treadmill test. 2, 24 twice within 72 h determine test-retest reliability. required participants complete bouts 5 × 12 s shuttle at progressively faster speeds until volitional exhaustion. were separated by 6 recovery periods, making each...
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...
This study examined the effects of pre-exercise carbohydrate availability on time to exhaustion for moderate and heavy exercise. Seven men participated in a randomized order two diet exercise regimens each lasting 3 days with 1-week interval washout. The tests were performed at 50% difference between first (LT1) second (LT2) lactate breakpoint (below LT2) 25% maximal load LT2 (above until exhaustion. Forty-eight hours before experimental session, subjects 90-min cycling followed by 5-min...
We examined the effect of acute and chronic sprint interval training (SIT), with or without prior caffeine intake, on levels exercise-induced inflammatory plasma cytokines (interleukin (IL)-6, IL-10, tumor necrosis factor (TNF)-α. Twenty physically-active men ingested either a placebo (n = 10) one hour before each SIT session (13 x 30-s sprint/15 s rest) during six sessions (2 weeks). The early (before, immediately after, 45 min after exercise) late (24 48 h cytokine creatine kinase (CK)...
The menstrual cycle (MC) phases carry to several psychophysiological alterations; however, no study has investigated the impact of MC on training load or technical training. In present study, we effect follicular phase (FP), ovulatory (OP), and luteal (LP) in young athletes. Twelve female athletes performed regular daily sessions with rating perceived exertion (RPE) duration being registered every session. Training impulse (TRIMP), monotony strain were calculated. symptoms, RPE, also...
Modified silica nanoparticles (NPs) were obtained by esterification of the silanol groups fumed with 4-hydroxymethyl-N,N-dimethylbenzenamine. These particles characterized Fourier transform infrared spectroscopy, 13C and 29Si nuclear magnetic resonance, thermogravimetry, X-ray photoelectron transmission electron microscopy energy-dispersive measurement specific surface area. Laser flash photolysis experiments at excitation wavelength 532 nm performed safranine-T NP suspensions in...
Ethanolamine (E) and diethanolamine (D) molecules were incorporated onto a precursor 3-glycidoxypropyltrimethoxysilane (G) agent, followed by organofunctionalization of the silica gel through homogeneous (A) heterogeneous (B) routes, to yield SiEA, SiDA, SiEB SiDB hybrids. These chemically organofunctionalized silicas characterized several techniques, including infrared spectroscopy (FTIR), solid-state nuclear magnetic resonance (13C 29Si NMR using CP/MAS), thermogravimetry elemental...
The aim of this study was to test the hypothesis that reduced pre-exercise carbohydrate (CHO) availability potentiates fat oxidation after an exhaustive high-intensity exercise bout. Eight physically active men underwent a (∼95% V̇O2max) until exhaustion under low or high CHO availability. protocol manipulate consisted 90-min cycling bout at ∼70% V̇O2max + 6 × 1-min 125% with rest, followed by 48 h low- (10% CHO, low-CHO availability) high-CHO diet (80% availability). Time shorter and energy...
The purpose of this study was to investigate the difference between arterialized and venous blood lactate concentrations [La] during constant-load exercises at different intensities. Fifteen physically active men cycled for 30 minutes (or until exhaustion) first threshold (LT1), 50% second (TT50%), (LT2), 25% LT2 maximal aerobic power output (TW25%). Samples both were collected simultaneously rest every 5 exercise. higher minute than all exercise intensities (p < 0.05). After period, samples...
The aim of the study was to measure influence bent knee and loss contact warnings on lap speed in race walkers correlate with maximum minimum speeds. Fifty-four national (32 men 22 women, 22.8 ± 9.0 20.7 years old, respectively) participated study. pre-warnings, at moment post-warnings were compared, analysis between contact. Additionally, speeds associated warning compared given lower than (F(1) = 22.894, p 0.001). only negatively influenced athlete's (F(2) 11.430, 0.001) or (r 0.440,...
The objective of this study was to verify the agreement between pre-programmed and executed pacing during race walking whether level athletes experience performance influenced relationship. Twenty-nine national international walkers participated in (14 males, 24.0±7.1 years old, 15 females, 23.3±7.3 old). Pre-programmed for 10- 20-km official races self-selected via demonstrative charts prior races, while analyzed by a specialist investigator an individual plot current velocity versus...
We investigated if carbohydrate (CHO) availability could affect the excess post-exercise oxygen consumption (EPOC) after a single supramaximal exercise bout. Five physically active men cycled at 115% of peak uptake (V̇O2 peak) until exhaustion with low or high pre-exercise CHO availability. The endogenous stores were manipulated by performing glycogen-depletion protocol 48 h before trial, followed consuming either low- (10% CHO) high-CHO (80% diet regime. Compared to low-CHO diet, increased...
