Abstract Microvascular impairments are typical of several cardiovascular diseases. Near‐infrared spectroscopy (NIRS) combined with a vascular occlusion test provides non‐invasive insights into microvascular responses by monitoring skeletal muscle oxygenation changes during reactive hyperaemia. Despite increasing interest in the effects sex and ageing on responses, evidence remains inconsistent. Therefore, present study aimed to investigate age responsiveness. Twenty‐seven participants (seven...

This study examined the effect of high- (HPBPT) and low-percentage ball possession (LPBPT) on physical technical indicators during 2014 FIFA World Cup matches. would enable a regression model to be constructed further understand impact different (BP) strategies match performance. Data were collected from 346 international soccer players using multiple-camera computerised tracking system. Although in HPBPT covered lower distances (P < 0.01) total at low speed compared LPBPT, this produced...

The acute effect of ischemic preconditioning (IPC) on the maximal performance in 100-m freestyle event was studied recreational swimmers. 15 swimmers (21.0±3.2 years) participated a random crossover model 3 different days (control [CON], IPC or SHAM), separated by 3–5 days. consisted 4 cycles 5-min occlusion (220 mmHg)/5-min reperfusion each arm, and SHAM protocol similar to but with only 20 mmHg during phase. subjects were informed that both maneuvers (IPC SHAM) would improve their...

This study evaluated the effect of ischemic preconditioning (IPC) on resistance exercise performance in lower limbs. Thirteen men participated a randomized crossover design that involved 3 separate sessions (IPC, PLACEBO, and control). A 12-repetition maximum (12RM) load for leg extension was assessed through test retest before first experimental session. The IPC session consisted 4 cycles 5 minutes occlusion at 220 mm Hg pressure alternated with reperfusion 0 total 40 minutes. PLACEBO cuff...

This study evaluated the effect of ischemic preconditioning (IPC) on resistance exercise performance in upper limbs. After 12-RM load determination, 21 men attended 4 trials separated by 3 days a randomized crossover design: IPC (4×5-min occlusion 220 mmHg/reperfusion 0 mmHg) arms and thighs, SHAM (equal to protocol but "occlusion" at 20 thighs. 8 min following respective interventions, subjects performed one set elbow flexion with until concentric failure. The number repetitions increased...

Compression garments, utilized in sports and exercise for performance enhancement recovery, lack sufficient well-controlled studies to overcome any potential placebo effect. Therefore, we tested whether wearing compressive pantyhose (CP) during the Ballet-specific aerobic fitness test (BAFT) would influence performance, physiological, perceptual indicators. Additionally, this pilot study feasibility of research procedures informed adjustments main study. Nine young classical ballerinas...

We thank Schumann et al. (Schumann, Feuerbacher 2024) for their engagement and thoughtful comments on our article (Ide, Silvatti 2023), the overarching use of terminology in sports science. Academic debate is critical advancing field, we welcome opportunity to clarify expand arguments. While comment offers a perspective practical use, maintain that application “explosive” scientific literature may be both unnecessary potentially misleading.

We determined the optimal load for peak power output (PPO) during bench press throw (BPT) in Brazilian Jiu-Jitsu (BJJ) athletes and compared PPO maximal strength between advanced (AD) nonadvanced (NA) athletes. Twenty-eight BJJ (24.8 ± 5.7 years) performed BPT at loads of 30, 40, 50, 60% their 1 repetition maximum (RM) a randomized order (5-minute rest BPTs). The was by measuring barbell displacement an accelerometer (Myotest). absolute (F = 7.25; p < 0.001; effect size [ES] 0.21) relative...

Correction to: Acute Effect of Ischemic Preconditioning is Detrimental to Anaerobic Performance in CyclistsInt J Sports Med 2014; 35(11): 912-915DOI: 10.1055/s-0034-1372628

This study evaluated the acute effect of ischemic preconditioning (IPC) on a high-intensity intermittent exercise performance and physiological indicators in amateur soccer players. Thirteen players (21.5 ± 2 yrs) attended three trials separated by 3–5 days counterbalanced randomized cross-over design: IPC (4 × 5-min occlusion 220 mmHg/reperfusion 0 mmHg) each thigh; SHAM (similar to protocol but “occlusion” at 20 control (seated during same time IPC). After 6-min trial (IPC, or control),...

We verified the acute effect of ischemic preconditioning (IPC) in cyclists before high-intensity and short-duration activity. 15 amateur participated a random crossover model on 2 different days [IPC or CONTROL (CON)]. Ischemic consisted 4 cycles 5 min occlusion/5 reperfusion each thigh. After IPC CON, volunteers performed series Wingate tests to evaluate anaerobic performance (maximal [Pmax] medium [Pmed] power output, total power, fatigue index). Blood lactate concentrations were assessed...

Amputee football is a variation of conventional soccer in which athletes with lower limb amputation and one athelete upper (the goalkeeper) participate. The objective this study was to investigate the anthropometric physical characteristics amputee verify differences between heart rate peak (HRpeak) equations for predicting maximum (HRmax). Twelve players from Brazilian team participated study. body mass, height composition were measured. tests used were: 20 m running test, T-square test Yo...

Abstract The aim of this study was to investigate the neuromuscular performance responses following successive Brazilian Jiu-Jitsu (BJJ) fights. Twenty-three BJJ athletes (age: 26.3 ± 6.3 years; body mass: 79.4 9.7 kg; height: 1.80 0.1 m) undertook 3 simulated fights (10 min duration each separated by 15 rest). Neuromuscular measured bench press throw (BPT) and vertical counter movement jump (VCMJ) tests, assessed before 1st fight (Pre) after last one (Post). Blood lactate (LA) at Pre, 1...

The present study tested the hypothesis that resistance-trained individuals would also show less muscle damage in second than first eccentric exercise bout (i.e., repeated effect) as shown untrained individuals. This investigated changes indirect markers of after 2 bouts free weight performed by 8 men. participants (24.4 ± 1.2 years) 4 sets actions (3 seconds for each repetition) at 70% 1 repetition maximum (1RM) load a bench press with minutes rest between sets, and same weeks later. Bench...

Brief moments of blood flow occlusion followed by reperfusion may promote enhancements in exercise performance. Thus, this study assessed the 24-h effect post-exercise ischemic conditioning (PEIC) on performance and physiological variables trained cyclists. In a randomized, single-blind study, 28 cyclists (27.1 ± 1.4 years) performed maximal incremental cycling test (MICT). The outcome measures were creatine kinase (CK), muscle soreness perceived recovery status, heart rate, exertion power...

We investigated the match demands (distances covered and acute physiological responses) of amputee soccer its impact on muscular endurance power. Measures such as heart rate, blood lactate concentration, subjective rating perceived exertion, time-motion characteristics were recorded in 16 Brazilian players during matches. Before after matches, completed a battery tests: push-ups, countermovement vertical jump performance, medicine ball throwing. Small differences found between first second...

After menopause, rapid bone mass loss occurs in response to hypoestrogenism. Several studies suggest that muscle and mineral density (BMD) are positively associated postmenopausal women. Therefore, it may be assumed low appendicular (aMM) can increase BMD a short period of time. The purpose this study was assess relationship aMM with femoral neck Prospective, controlled clinical Trial including 64 women aged 45-70 years, who had not their last menstruation for at least one year. Subjects...

The purpose of this study was to evaluate the time course strength and power recovery after a single bout training designed with fast slow contraction velocities. Nineteen male subjects were randomly divided into 2 groups: slow-velocity (SV) group velocity (FV) group. Resistance protocols consisted 5 sets 12 repetition maximum (5 × 12RM) 50 seconds rest between minutes exercises. Contraction controlled by execution for each (SV-6 complete concentric eccentric phases FV-1.5 seconds). Leg...
