Abstract Coaches and athletes in elite sports are constantly seeking to use innovative advanced training strategies efficiently improve strength/power performance already highly-trained individuals. In this regard, high-intensity conditioning contractions have become a popular means induce acute improvements primarily muscle contractile properties, which supposed translate subsequent power performances. This performance-enhancing physiological mechanism has previously been called...

Purpose The present study was designed to provide mechanistic insight into the time course and etiology of muscle fatigue development recovery during after low-intensity exercise when it is combined with blood flow restriction (BFR). Methods Seventeen resistance-trained males completed four sets isotonic resistance under two experimental conditions: knee extension (i) BFR (ii) without (CON). Neuromuscular tests were performed before, (immediately each set exercise), 1, 2, 4, 8 min condition....

This study investigated effects of caffeine ingestion (8 mg/kg) on maximum voluntary torque (MVT) and activation the quadriceps during isometric, concentric eccentric contractions. Fourteen subjects ingested placebo in a randomized, controlled, counterbalanced, double-blind crossover design. Neuromuscular tests were performed before 1 h after oral intake. MVTs measured interpolated twitch technique was applied contractions to assess activation. Furthermore, normalized root mean square EMG...

Mental fatigue is a psychobiological state induced by sustained periods of demanding cognitive activity and characterized feelings tiredness which are common in everyday life. Recently, it has been hypothesized that mental might have an impact on gait performance old adults. Therefore, the effect under single- dual-task conditions was investigated young participants.Spatio-temporal parameters 16 healthy participants were measured using photoelectric system during walking before after...

The present study was designed to provide further insight into the mechanistic basis for improved exercise tolerance following dietary nitrate supplementation. In a randomized, double-blind, crossover design, twelve recreationally active males completed dynamic time-to-exhaustion test of knee extensors after 5 days consuming both nitrate-rich (NITRATE) and nitrate-depleted beetroot juice (PLACEBO). Participants who their NITRATE performed time-matched trial corresponding PLACEBO duration...

The link between mental representation (MREP) structures and motor performance has been evidenced for a great variety of movement skills, but not the human gait. Therefore present study sought to investigate cognitive memory underlying gait in young older adults. In first experiment, parameters at comfortable speed (OptoGait) were compared with gait-specific MREPs (structural dimensional analysis MREP; SDA-M) 36 Participants divided into slow- fast-walking group. proven relationship...

This study investigated neuromuscular adaptations of the knee extensors after 8 weeks plyometric training. 23 subjects were randomly assigned to an intervention group and a control group. We measured isometric maximum voluntary torque (iMVT), rate development (RTD) impulse (IMP) over different time intervals. The neural drive muscles was estimated with interpolated twitch technique normalized root mean square EMG signal. Contractile properties, H reflexes as well jump height in squat (SJ)...

Nonlinear parameters of heart rate variability (HRV) have proven their prognostic value in clinical settings, but physiological background is not very well established. We assessed the effects low intensity isometric (ISO) and dynamic (DYN) exercise lower limbs on matched traditional entropy measures HRV. Due to changes afferent feedback under DYN ISO a distinct autonomic response, mirrored by HRV measures, was hypothesized. Five-minute inter-beat interval measurements 43 healthy males (26.0...

In the present study, we investigated whether inter-individual differences in vagally mediated heart rate variability (vmHRV) would be associated with empathy and alexithymia. To this end, determined resting state HF-HRV 90 individuals that also completed questionnaires assessing Our categorical dimensional analyses revealed were differently We found high reported more less alexithymia than low HF-HRV. Moreover, even an increase was a decrease across all participants. Taken together, these...

The parallel-group randomized active-controlled clinical study was conducted to compare the effectiveness of two in-hospital range motion (ROM) exercise programs following total knee arthroplasty (TKA). Continuous passive (CPM) is frequently used increase ROM and improve postoperative recovery despite little conclusive scientific evidence. In contrast, a new active sling-based therapy requires activation joint muscles dynamic stabilization. It hypothesized that higher demands on muscle...

Abstract During their daily lives humans are often confronted with sustained cognitive activities (SCA) leading to state fatigue, a psychobiological characterized by decrease in and/or motor performance an increase perception of fatigue. It was recently shown that performing SCA can impair overground dual-task gait older adults, but it is currently unknown whether there task- age-specific modulation during treadmill walking. Therefore, the effect on single- and walking investigated young old...

Abstract Objective To investigate the effect of a 12-week multimodal motor-cognitive and resistance training (MMI) compared to unimodal intervention (UMI) on static dynamic visual function in glaucoma patients (GLA) healthy controls (HC). Methods Fifteen GLA 24 age-matched HC participated this randomized, controlled longitudinal pilot study. Visual was assessed using clinical parameters and, treadmill, (TM) while standing (static, S 0 ) as well during walking at 3.5 km/h (S self-preferred...

<title>Abstract</title> <bold>Purpose:</bold> Aging is an inevitable process leading, inter alia, to the loss of muscle mass as well decrease in physical and cognitive function. These age-related impairments translate into a reduced gait performance increased risk falls, which can be tackled with resistance training, Unimodal intervention (UMI). However, Multimodal (MMI), i.e. combined motor-cognitive might more promising approach increase function old adults. Therefore, this pilot study...
