Caffeine (CAF) is among the most extensively researched dietary supplements worldwide. However, little known about relationship between dosage and performance enhancement, particularly in female athletes. This study aimed to explore effects of three different CAF dosages (3 mg·kg−1, 6 9 mg·kg−1) on high-intensity exercise prevalence undesirable side related these doses team-sports All participants (n = 16; age: 16.9 ± 0.6 y; height: 1.64 0.1 m; BMI: 21.6 1.5 kg·m−2) were mild consumers. had...
Caffeine (CAF), a prevalent psychoactive stimulant, is believed to potentially enhance cognitive ability. However, studies on the effects of various doses are limited and yield inconsistent results, particularly in female athletes. Therefore, we aimed assess association between three different dosages CAF intake (low, moderate, high) skills athletes with low consumption. This study had randomized, crossover, double-blind design which each athlete performed four experimental sessions after...
This study examined the effects of two nap durations (40 minutes (N40) and 90 (N90)) on physical performance, sleepiness, attention, mood states (Profile Mood States, POMS), perceived exertion (RPE), pain perception (PP), recovery (PRS), delayed onset muscle soreness (DOMS) in well-trained women. Fourteen female boxers underwent digit cancellation test, POMS, 5-meter shuttle run test (5mSRT) under no-nap (N0), N40, N90 conditions after either normal sleep (NSN) or restriction (SRN). RPE PP...
The present study aimed to investigate the effect of timing last meal, "Suhoor", on diurnal variation in cognitive performance during Ramadan intermittent fasting (RIF). In a randomized order, 26 adolescent female athletes (aged 15.9 ± 0.9 y) were tested three sessions at 7:00 a.m., 12:00 p.m., and 5:00 p.m. across four different conditions: 10 days preceding (PR); final 12 (RO): two Early Suhoor (S
This study compares the effects of coach verbal encouragement (CVE) and peer (PVE) on CrossFit-specific one-repetition maximum (1-RM) strength, functional endurance, psychophysiological assessments. A total 36 sports science students (18 males, 18 females; mean age: 21.3 ± 0.5 years) participated in a randomized, counterbalanced crossover which 1-RM strength endurance assessment sessions were undertaken under PVE, CVE, no (NVE) separate days. Here, was assessed through squat, deadlift, bench...
This comparative study investigates the effectiveness of two teaching methods, individual verbal encouragement and collective encouragement, in enhancing technical–tactical skills mood state obese students during handball matches. employs a randomized controlled design involves 28 overweight (50% females), age: 17.4 ± 2.08 years BMI: 26.8 1.5 for females 27.3 2.1 males. Technical–tactical are assessed through performance metrics (individual evaluation proposal by Gréhaigne) such as Ball...
Abstract The paradoxical effects of contextual interference (CI) assume that high CI practices hinder performances during the acquisition phase learning, while providing more permanent enhancement retention phase. This meta-analysis evaluates possible generalizability phenomenon in physical education (PE) and sports contexts, with regard to acute relatively gains performance outcomes. A total 933 records from five electronic databases were screened using PICOS criteria, which 36 studies...
The increasing prevalence of age-related cognitive decline, alongside the aging global population, underscores urgent need for innovative and effective preventative strategies. While advantages combining physical exercises have been recognized as a promising approach to address these socioeconomic challenges, acute effects such interventions on functions remain understudied. This study aimed investigate whether simultaneous exercise has greater beneficial impact older adults with mild...
Despite the development of various motor learning models over many decades, question which model is most effective under conditions to optimize acquisition skills remains a heated and recurring debate. This particularly important in connection with sports movements high strength component. study aims examine acute effects on technical efficiency force production during Olympic snatch movement. In within-subject design, sixteen highly active male participants (mean age: 23.13 ± 2.09 years),...
Aiming to identify the ideal suhoor timing for maintaining optimal physical performance and health indicators during Ramadan intermittent fasting, present study compares effects of early vs. late Suhoor on short-term high-intensity exercise while controlling body mass index (BMI) oral temperature (OT), dietary intake, sleep patterns. In a randomized design, 19 female pre-university handball players (age: 16.8 ± 0.4 y; height: 1.70 0.9 m; mass: 61.5 6.9 kg) underwent two test sessions (at...
Effective sports training should be attuned to the athlete’s specific conditionings and characteristics. In motor learning research, two often neglected factors that influence this resonance are learner’s athletic background structural diversity of exercises (e.g., relative similarity). setting real-word with higher external validity, study examines effects three approaches (i.e., contextual interference (CI), differential (DL), free-play control condition (CO)) on parallel handball (HB),...
Background: Caffeine is the most consumed psychoactive substance globally, second only to water in beverage consumption. Its impact on athletic performance, particularly team sports, has been a subject of growing research interest. This review focuses recent studies investigating caffeine's influence various aspects ball sports performance. Objectives: mini-review aimed (i) synthesize current findings caffeine supplementation considering different doses, forms, and its effects across genders...
BACKGROUND: In sports science, optimizing athletic performance is pursued through an emerging approach that combined light-loaded squat (LLS) training and plyometric jump (PJT), targeting strength, power, neuromuscular adaptations, particularly beneficial for the dynamic demands of youth soccer. The aim this study was to examine effect a LLS PJT program on balance in soccer players.METHODS: Thirty-two male players were randomly assigned two groups: experimental group (EG: N.=16; age:...
Introduction The present study aimed to evaluate the effect of acute aerobic exercise on certain cognitive functions known be affected by Alzheimer's disease (AD), with a particular emphasis sex differences. Methods A total 53 patients, mean age 70.54 ± 0.88 years and moderate AD, voluntarily participated in study. Participants were randomly assigned two groups: experimental group (EG), which 20-min moderate-intensity cycling session (60% individual maximum target heart rate recorded at end...
Abstract This study examined the effect of acute acetaminophen (ACTP) ingestion on physical performance during 5 m shuttle run test (5mSRT), attention, mood states, and perception perceived exertion (RPE), pain (PP), recovery (PRS), delayed onset muscle soreness (DOMS) in well-trained female athletes. In a randomized, placebo-controlled, double-blind, crossover trial, fifteen athletes (age 21 ± 2 years, height 165 6 cm, body mass 62 kg) swallowed either 1.5 g ACTP or placebo. The profile...
While previous studies have explored a range of factors governing the optimal use caffeine (CAF) in athletes, limited research has how time day (TOD) affects ergogenic effects various CAF dosages on physical performance. This study aimed to increase knowledge about different recommended doses (3 mg/kg vs. 6 mg/kg) ingested at TODs affected maximal high-intensity performance and perception potential side female athletes. In this double-blind, randomized, counterbalanced study, 15 low consumer...
<ns3:p>Background Sleep hygiene education (SHE) and lavender essential oil (LEO) inhalation are two effective strategies aimed at enhancing sleep quality mood states. This study investigated the effects of a single SHE session combined with nightly LEO for 7 days late-evening resistance training sessions on states in trained athletes. Methods Forty-two athletes were randomly assigned to four groups: control group (CG), (SHEG), (LEOG), + (CSLG). CG LEOG maintained their habits during...
Despite the growing body of evidence highlighting individuality in movement techniques, predominant models motor learning, particularly during acquisition phase, continue to emphasise generalised, person-independent approaches. Biomechanical studies, coupled with machine learning approaches, have demonstrated uniqueness techniques exhibited by individuals. However, this predominantly pertains already stabilised evident cyclic daily activities such as walking, running, or cycling, well...
