TL;DR: An interesting finding was that heat stress did not affect motor and cognitive function in either group, although central fatigue during 1-min maximal voluntary contraction increased after heat stress in both groups.
Abstract: Purpose: The main aim of this study was to compare physiological and psychological reactions to heat stress between people who exhibited fast cooling (FC, n = 20) or slow cooling (SC; n = 20) responses to 14 °C cold water immersion. Methods: Forty healthy young men (19–25 years old) were recruited to this study based on their tolerance to cold exposure (FC versus SC). The heat stress was induced using immersion in bath water at 43–44 °C. Motor and cognitive performance, immune variables, markers of hypothalamic–pituitary–adrenal axis activity (i.e. stress hormone concentrations), and autonomic nervous system activity were monitored. Results: In the FC group, time to warm the body from a resting rectal temperature (Tre) of 37.1 ± 0.2 °C before warming to 39.5 °C was 63.7 ± 22.4 min. In the SC group, the time to warm the body from a Tre 37.1 ± 0.3 °C before warming to 39.5 °C was 67.2 ± 13.8 min (p > 0.05 between groups). The physiological stress index (PSI) after warming was 8.0 ± 0.6 and 8.2 ± 1.0...

TL;DR: It is suggested that, in basketball SSGs, shorter regimes induce higher technical demands, while tactical tasks influence perceived exertion responses and mental effort, which appears significantly associated with variations of mental fatigue induced by training drills.
Abstract: This study aimed to evaluate the technical-tactical, perceptual and mental demands of basketball small-sided games (SSGs). Twelve male semi-professional players participated in four half-court 3vs3 SSGs characterized by different tactical tasks (offensive; defensive) and training regimes (long-intermittent; short-intermittent). The SSGs were video-recorded to perform notational analysis of technical-tactical parameters. Ratings of perceived exertion (RPE, CR-100 scale), mental effort (ME) and e njoyment were collected after completion of each SSG. Before and after the SSGs, players reported their perceived mental fatigue (MF); for this indicator, the difference between post- and pre-SSG values was calculated (ΔMF). Notational analysis evidenced a higher volume of play (ball possessions, ball possessions per minute) [large effect size (ES)], dribbles and shot attempts (moderate ES) in short-intermittent regimes compared to long-intermittent. Two-way (tactical task; training regime) repeated-measures ANOVA showed an interaction effect for RPE (moderate ES). Players reported that playing the offensive task required higher mental effort compared to playing defence (moderate ES), while no differences for mental effort were found between regimes. Enjoyment did not differ between tasks or regimes. No effects were found for ΔMF, while this indicator was significantly correlated with RPE scores (r= 0.50, large). This study suggests that, in basketball SSGs, shorter regimes induce higher technical demands, while tactical tasks influence perceived exertion responses and mental effort. Furthermore, perceived exertion appears significantly associated with variations of mental fatigue induced by training drills.

TL;DR: In this paper, the effect of increasing exercise intensity on the magnitude and location of any changes in electrocortical current density was investigated on a cycle ergometer, and the results indicated that the combined active EEG/LORETA method allows for the recording of brain cortical activity during complex movements and incremental exercise.
Abstract: While the effects of exercise on brain cortical activity from pre-to post-exercise have been thoroughly evaluated, few studies have investigated the change in activity during exercise. As such, it is not clear to what extent changes in exercise intensity influence brain cortical activity. Furthermore, due to the difficulty in using brain-imaging methods during complex whole-body movements like cycling, it is unclear to what extent the activity in specific brain areas is altered with incremental exercise intensity over time. Latterly, active electroencephalography (EEG) electrodes combined with source localization methods allow for the assessment of brain activity, measured as EEG current density, within specific cortical regions. The present study aimed to investigate the application of this method during exercise on a cycle ergometer, and to investigate the effect of increasing exercise intensity on the magnitude and location of any changes in electrocortical current density. Subjects performed an incremental cycle ergometer test until subjective exhaustion. Current density of the EEG recordings during each test stage, as well as before and after exercise, was determined. Spatial changes in current density were localized using low-resolution brain electromagnetic tomography (LORETA) to three regions of interest; the primary motor cortex, primary sensory cortex and prefrontal cortex, and were expressed relative to current density within the local lobe. It was demonstrated that the relative current density of the primary motor cortex was intensified with increasing exercise intensity, whereas activity of the primary sensory cortex and that of the prefrontal cortex were not altered with exercise. The results indicate that the combined active EEG/LORETA method allows for the recording of brain cortical activity during complex movements and incremental exercise. These findings indicate that primary motor cortex activity is elevated with incremental exercise intensity during a whole-body movement, like cycling.

TL;DR: This systematic review comprehensively evaluated the current body of literature related to training load monitoring in basketball and provided specific guidelines for defining and applying duration measurement methodologies, vetting the validity and reliability of measurement tools, and classifying competition level in basketball to address some of the identified knowledge gaps.
Abstract: Measuring the physical work and resultant acute psychobiological responses of basketball can help to better understand and inform physical preparation models and improve overall athlete health and performance. Recent advancements in training load monitoring solutions have coincided with increases in the literature describing the physical demands of basketball, but there are currently no reviews that summarize all the available basketball research. Additionally, a thorough appraisal of the load monitoring methodologies and measures used in basketball is lacking in the current literature. This type of critical analysis would allow for consistent comparison between studies to better understand physical demands across the sport. The objective of this systematic review was to assess and critically evaluate the methods and technologies used for monitoring physical demands in competitive basketball athletes. We used the term ‘training load’ to encompass the physical demands of both training and game activities, with the latter assumed to provide a training stimulus as well. This review aimed to critique methodological inconsistencies, establish operational definitions specific to the sport, and make recommendations for basketball training load monitoring practice and reporting within the literature. A systematic review of the literature was performed using EBSCO, PubMed, SCOPUS, and Web of Science to identify studies through March 2020. Electronic databases were searched using terms related to basketball and training load. Records were included if they used a competitive basketball population and incorporated a measure of training load. This systematic review was registered with the International Prospective Register of Systematic Reviews (PROSPERO Registration # CRD42019123603), and approved under the National Basketball Association (NBA) Health Related Research Policy. Electronic and manual searches identified 122 papers that met the inclusion criteria. These studies reported the physical demands of basketball during training (n = 56), competition (n = 36), and both training and competition (n = 30). Physical demands were quantified with a measure of internal training load (n = 52), external training load (n = 29), or both internal and external measures (n = 41). These studies examined males (n = 76), females (n = 34), both male and female (n = 9), and a combination of youth (i.e. under 18 years, n = 37), adults (i.e. 18 years or older, n = 77), and both adults and youth (n = 4). Inconsistencies related to the reporting of competition level, methodology for recording duration, participant inclusion criteria, and validity of measurement systems were identified as key factors relating to the reporting of physical demands in basketball and summarized for each study. This review comprehensively evaluated the current body of literature related to training load monitoring in basketball. Within this literature, there is a clear lack of alignment in applied practices and methodological framework, and with only small data sets and short study periods available at this time, it is not possible to draw definitive conclusions about the true physical demands of basketball. A detailed understanding of modern technologies in basketball is also lacking, and we provide specific guidelines for defining and applying duration measurement methodologies, vetting the validity and reliability of measurement tools, and classifying competition level in basketball to address some of the identified knowledge gaps. Creating alignment in best-practice basketball research methodology, terminology and reporting may lead to a more robust understanding of the physical demands associated with the sport, thereby allowing for exploration of other research areas (e.g. injury, performance), and improved understanding and decision making in applying these methods directly with basketball athletes.

TL;DR: To investigate what triggers cognitive and neuromuscular alterations during passive heat exposure, eight volunteers performed simple and complex cognitive tasks as well as neuromUScular testing in both hot and neutral environments.
Abstract: Background:Methodological discrepancies between studies have made it difficult to conclude whether heat exposure does or does not adversely affect cognitive function and under what specific environmental and physiological conditions these alterations appear.Purpose:To investigate what triggers cognitive and neuromuscular alterations during passive heat exposure.Methods: Eight volunteers performed simple (OTS-4) and complex (OTS-6) cognitive tasks as well as neuromuscular testing (maximal isometric voluntary contractions of the thumb with electrical stimulation of the motor nerve and magnetic stimulation of the motor cortex). These tests were performed at the start (T1), after 1h30 (T2), 3h (T3) and 4h30 (T4) of exposure in both hot (HOT, WBGT = 38 ±1.4°C) and neutral (CON, WBGT = 19 ±0.3°C) environments. Environmental temperatures were adjusted during the HOT session to induce target core temperatures (Tcore) (T1 ∼37.3; T2 ∼37.8; T3 ∼38.3; T4 ∼38.8oC).Results:There were global effects of time (p <...
