The purpose of this study is to examine the effects different volume and training surfaces during a short-term plyometric program on neuromuscular performance. Twenty-nine subjects were randomly assigned 4 groups: control group (CG, n = 5), moderate (MVG, 9, 780 jumps), hard surface (MVGHS, 8, high (HVG, 7, 1,560 jumps). A series tests performed by before after 7 weeks training. These measurement maximum strength (5 repetitions [5RMs]), drop jumps (DJs) varying heights (20, 40, 60 cm), squat...
The aim of the study was to compare effects bilateral, unilateral, or combined bilateral and unilateral plyometric training (PT) on muscle power output, endurance, balance performance adaptations in young soccer players. Four groups players (age 11.4 ± 2.2 years) were divided into control group (CG; n = 14), (BG; 12), (UG; 16), + (B UG; 12). Players measured countermovement jump with arms, 5 multiple bounds test, 20-cm drop reactive strength index, maximal kicking velocity, sprint agility...
Integrating specific training methods to improve explosive actions and endurance in youth soccer is an essential part of players' development. This study investigated the efficiency short-term vertical plyometric program within practice both young players. Seventy-six players were recruited assigned either a group (TG; n = 38; 13.2 ± 1.8 years) or control (CG; group. All trained twice per week, but TG followed 7-week implemented practice, whereas CG regular practice. Twenty-meter sprint time...
The purpose of this study was to examine the effect a short-term plyometric training program on explosive strength and endurance performance in highly competitive middle- long-distance runners. Athletes were randomly assigned control group (CG, n = 18, 12 men) an (TG, 10 men). Drop jump (DJ) from 20 (DJ20) 40 cm (DJ40), countermovement with arms (CMJA), 20-m sprint time, 2.4-km run time test carried out before after 6 weeks training. Also, combined standardized (CSP) analyzed. After...
Chronic intermittent hypoxia (CIH), the main feature of obstructive sleep apnea, enhances carotid body (CB) chemosensory responses to and produces autonomic dysfunction, cardiac arrhythmias, hypertension. We tested whether alterations, arrhythmogenesis, progression hypertension induced by CIH depend on enhanced CB drive, ablation chemoreceptors. Male Sprague-Dawley rats were exposed control (Sham) conditions for 7 days then (5% O2, 12/h 8 h/d) a total 28 days. At 21 exposure, underwent...
The purpose of this study was to compare the acute effects general, specific and combined warm-up (WU) on explosive performance. Healthy male (n = 10) subjects participated in six WU protocols a crossover randomized design. Protocols were: passive rest (PR; 15 min rest), running (Run; 5 at 70% maximum heart rate), stretching (STR; static exercise), jumping [Jump; exercises - 3x8 countermovement jumps (CMJ) drop from 60 cm (DJ60)], (COM; Run+STR+Jump combined). Immediately before after each...
The purpose of the study was to compare effects progressive volume-based overload with constant on muscle explosive and endurance performance adaptations during a biweekly short-term (i.e., 6 weeks) plyometric training intervention in young soccer players. Three groups players (age 13.0 ± 2.3 years) were divided into: control (CG; n = 8) (PPT; without (NPPT; increase volume 16 jumps per leg week, an initial 80 each session). Bilateral unilateral horizontal vertical countermovement jump arms...

J Strength Cond Res 29(4): 972–979, 2015—The purpose this study was determine the short-term interposed with 24 or 48 hours between sessions explosive endurance adaptations A total 166 players, 10 17 years age, were randomly divided into 3 groups:...
Heart failure with preserved ejection fraction (HFpEF) is associated disordered breathing patterns, and sympatho-vagal imbalance. Although it well accepted that altered peripheral chemoreflex control plays a role in the progression of heart reduced (HFrEF), pathophysiological mechanisms underlying deterioration cardiac function HFpEF are poorly understood. We found central enhanced neuronal activation increased pre-sympathetic regions brainstem. Our data showed pathway exacerbates diastolic...
Activation of oxytocin receptors has shown benefits in animal models obstructive sleep apnea (OSA). We tested if nocturnal administration could have beneficial effects OSA patients. Eight patients diagnosed with were administered intranasal (40 IU). Changes cardiorespiratory events during sleep, including and hypopnea durations frequency, risk event-associated arousals, heart rate variability, assessed. Oxytocin significantly increased indexes parasympathetic activity, total time, the...
Accurate short- and mid-term blood glucose predictions are crucial for patients with diabetes struggling to maintain healthy levels, as well individuals at risk of developing the disease. Consequently, numerous efforts from scientific community have focused on predictive models levels. This study harnesses physiological data collected wearable sensors construct a series data-driven based deep learning approaches. We systematically compare these offer insights practitioners researchers...

J Strength Cond Res 34(12): 3395-3402, 2020-The aim this study was to assess jumping performance activity in lower limb muscles after drop jumps (DJs) from different heights (intensity) continuous (fatigue), using markers such as reactive strength, jump height, mechanical power surface electromyography (sEMG). The...
Heart rate variability and resting metabolic are commonly to assess athlete's physiological status energy requirements. Exercise-induced dehydration can reach up 5% of body mass per hour. Consequently, may have a profound effect on human's homeostasis.To compare the effects rehydration after exercise heart in college athletes.14 athletes were divided into group (n=7) (n=7), both submitted basal (T1) measurements. After measurements groups actively dehydrated (-3.4 ± 0.4% for groups)....
Age represents the highest risk factor for death due to cardiovascular disease.Heart failure (HF) is most common disease in elder population and it associated with cognitive impairment (CI), diminishing learning memory process affecting life quality mortality these patients.In HF, CI has been inadequate O 2 supply brain; however, an important subset of HF patients displays almost no alteration cerebral blood flow.Importantly, nothing known about pathophysiological mechanisms underpinning...
