This study analyzed the effects of caffeine ingestion during judo matches on judo athletes' match-derived performance and perceived exertion responses. We applied a double-blind randomized crossover (caffeine vs. placebo conditions) research design. Twelve male athletes performed three 5-minute matches separated by 15 minutes of passive rest. Immediately after each match, the athletes completed ratings of perceived exertion (RPEs), and one minute before beginning the second and third matches, they provided ratings of perceived recovery (RPRs)...

The present study aimed to investigate whether the form and amount of declarative tactical knowledge (DTK) and procedural tactical knowledge (PTK) influence cognitive effort during soccer performance among young players. We assessed 36 male players from a Brazilian first-division soccer club; participants averaged 14.89 ( SD = 1.42) years of age. We evaluated DTK from video simulation tests and PTK through the System of Tactical Assessment in Soccer. We assessed cognitive effort by measures of pupil diameter using Mobile Eye Tracking-XG while players viewed soccer video scenes and made game-related play decisions...

Physical activity has been positively related to better cognitive performance though the effects of varied exercise type and intensity and the duration of cognitive benefits are unclear. This study analyzed the effect of 16 minutes of monitored cooperative high-intensity interval training (monitored C-HIIT) at the start of the school day, on various cognitive variables over the next 24-48 hours. We randomly assigned 158 participants either to a control group ( n = 81) that engaged only in static stretching or to an experimental group ( n = 77) that performed monitored C-HIIT...

The relationship between emotional intelligence (EI) and successful athletic performance has been previously recognized, but there remains a need to investigate how EI impacts athletes' sports motivation. This cross-sectional study investigated how different EI dimensions related to athletes' motivation among 239 adult basketball players (129 females) aged 18-34 years. Our research participants completed questionnaires that included the self-reported Emotional Intelligence Scale and Sport Motivation Scale II...

This study translated, adapted, and validated the Sport Commitment Questionnaire-2 (SCQ-2) for the Spanish language and cultural context. We utilized a cross-sectional design with 747 athlete participants (436 males, 311 females), ranging in age from 11-24 years ( M = 16.04; SD = 2.57). Participants were involved in a variety of individual and team sports and were from various autonomous regions of Spain. Participants completed the Spanish-language version of the SCQ-2 developed for this study. Confirmatory factor analysis demonstrated acceptable fit of the proposed factor structure and gender invariance for the new Spanish language scale...

This study investigated the effects of red and blue monochromatic lights and neuroticism on athletes' maximal isometric voluntary contraction (iMVC) level of the biceps brachii muscle. During elbow flexion, we measured iMVCs under a white light (control) condition and under red and blue light conditions. Under red light (vs. white and blue), participants demonstrated a greater iMVC level. Further, based on a median split of the athletes' scores on Tatar's Five Factor Personality Inventory, high and low neuroticism groups showed no red light differences, while, in the blue light condition, participants high in neuroticism increased the iMVC level by 4...

Tai Chi, yoga, and stretching regimens are gaining popularity as alternatives to more traditional exercise, but there is scant research regarding participants' perceived exertion and affective responses to these practices. We compared experienced states of perceived exertion, feelings of pleasure/displeasure, and arousal in 70 elderly women enrolled in groups of Tai Chi ( n = 26), yoga ( n = 25), or stretching ( n = 19) classes. Mean rates of perceived exertion, feelings of pleasure, and arousal responses were significantly higher over the time course of all three groups, while the overall mean perceived exertion ( Somewhat Hard on the Borg CR-10 scale) and pleasure responses (∼ Very Good on the Feeling Scale) were similar between them...

Using multilevel analysis, this study examined a cross-level effect of paternalistic leadership and team cohesion on athletes' burnout. We called 900 athletes from 28 colleges to participate in this survey, with a return rate of 85.2% and found that paternalistic leadership of coaches had a cross level effect across schools on athletes' burnout. Based on these findings, we propose recommendations for coaches and school administrators.

This study examined the effects of age and walking experience on infants' ability to step over an obstacle. We videotaped 30 infants with one (mean [ M] age = 12.6 months), three ( M age = 14.7 months), and six months ( M age = 17.7 months) of walking experience walking on a pathway with and without an obstacle. We found a shorter stride and slower velocity for infants with one month of walking experience and for the walking condition with an obstacle than for other experience groups or for walking without an obstacle...

The d2 test is a cancellation test to measure attention, visual scanning, and processing speed. It is the most frequently used test of attention in Europe. Although it has been validated using factor analytic techniques and correlational analyses, its fit to item response theory models has not been examined. We evaluated the fit of the d2 test to the Rasch Poisson Counts Model (RPCM) by examining the fit of six different scoring techniques. Only two scoring techniques-concentration performance scores and total number of characters canceled-fit the RPCM...

This study investigated the effects of Parkinson's Disease (PD) on the perceptive judgment of stair step height using both exteroceptive visual and exproprioceptive judgments. We invited 14 individuals with PD and 14 neurologically healthy older adults (OA) to perform perceptual judgment tasks for first step stairway heights of 11 and 20 cm. Initially, participants performed first the exteroceptive visual judgment and then the exproprioceptive judgment in five randomized trials for each stair height. An analysis of variance for the exteroceptive visual judgment revealed no main effects or interaction between PD versus OA groups and height...

We assessed the short-term effects of varying the volume of high-intensity interval training (HIIT) on psychological and physiological responses of 23 healthy adult males ( M = 21 years; M peak oxygen uptake [VO2peak ] = 47.2 ml·kg-1 ·min-1 ). Participants were randomly assigned to low- and very-low-volume HIIT groups and engaged in nine supervised exercise sessions over three weeks. The low-volume HIIT group performed 8-12 60-second work bouts on a cycle ergometer at the peak power output achieved during the incremental test, interspersed by 75 seconds of low-intensity active recovery...

This study investigated the relationship between length of hair in facial stimuli and latency and amplitude of the P1 and N170 components of event-related potentials during facial perception. Electroencephalography was recorded from 21 Japanese participants (four men, 17 women) who were shown pictures of faces with one of three lengths of hair: long, medium length, or short. In addition, we used both fixed-size and variable-size blocks. In fixed-size blocks, the three types of stimuli were matched to have the same overall size; in variable-size blocks, long hair stimuli were the biggest, medium length hair stimuli were medium sized, and short hair stimuli were the smallest...

Children's motor competence is known to have a determinant role in learning and engaging later in complex motor skills and, thus, in physical activity. The development of adequate motor competence is a central aim of physical education, and assuring that pupils are learning and developing motor competence depends on accurate assessment protocols. The MOBAK 1 test battery is a recent instrument developed to assess motor competence in primary physical education. This study used the MOBAK 1 to explore motor competence levels and gender differences among 249 ( Mage  = 6...

Kazufumi Omura, Shinya Matsuta
Many previous studies have investigated developmental differences in numerical processing by manipulating numerical distance and physical size in a number sequence. While it has been theorized that children's maturity level in executive functioning affects their numerical processing, the interaction between numerical processing and executive functioning through development remains unclear. We divided 60 Japanese school children, aged 8-12 years, into three age-related groups (second graders, fourth graders, and sixth graders) and had them perform physical and numerical comparison Stroop tasks...

Injuries sustained from traumatic brain injury (TBI) culminate in both cognitive and neuromuscular deficits. Patients often progress to higher functioning on the Rancho continuum even while mobility deficits persist. Although prior studies have examined physical performance among persons with chronic symptoms of TBI, less is known about the relatively acute phase of TBI as patients prepare for rehabilitation discharge. The aims of this cross-sectional study were to (a) compare balance and gait performance in 20 ambulant persons with moderate to severe TBI who were nearing rehabilitation discharge with their age-matched controls and (b) describe performance with thresholds for fall risk and community navigation...
