The present experiment sought to further understanding of the effects of personalised audiovisual stimuli on psychological and psychophysiological responses during exercise in adults with obesity. Twenty-four participants (Mage = 28.3, SD = 5.5 years; MBMI = 32.2, SD = 2.4) engaged in self-paced exercises on a recumbent cycle ergometer and three conditions (sensory stimulation [ST], sensory deprivation [DE], and control [CO]) were administered. Perceptual (attentional focus and perceived exertion), affective (affective state and perceived activation), and psychophysiological (heart rate variability) parameters were monitored throughout the exercise bouts. A one-way repeated measures analysis of variance was used to compare self-reported and psychophysiological variables (main and interaction effects [5 Timepoints × 3 Conditions]). The results indicate that ST increased the use of dissociative thoughts throughout the exercise session (ηp2 = .19), ameliorated fatigue-related symptoms (ηp2 = .15) and elicited more positive affective responses (ηp2 = .12) than CO and DE. Accordingly, personally-compiled videos are highly effective in ameliorating exertional responses and enhancing affective valence during self-paced exercise in adults with obesity. Audiovisual stimuli could be used during the most critical periods of the exercise regimen (e.g., first training sessions) when individuals with obesity are more likely to focus on fatigue-related sensations. 相似文献

Our purpose was to test the multi-action plan model assumptions in which athletes’ psychophysiological patterns differ among optimal and suboptimal performance experiences. Nine professional drivers competing in premier race categories (e.g. Formula 3, Porsche GT3 Cup Challenge) completed the study. Data collection involved monitoring the drivers’ perceived hedonic tone, accuracy on core components of action, posture, skin temperature, respiration rate and heart rate responses during a 40-lap simulated race. Time marks, gathered at three standardised sectors, served as the performance variable. The A1GP racing simulator (Allinsport, Modena) established a realistic race platform. Specifically, the Barcelona track was chosen because of its inherently difficult nature characterised by intermittent deceleration points. Idiosyncratic analyses showed large individual differences in the drivers’ psychophysiological profile, as well as distinct patterns in regards to optimal and suboptimal performance experiences. Limitations and future research avenues are discussed. Action- (e.g. attentional control) and emotion (e.g. biofeedback training)-centred applied sport psychology implications are advanced. 相似文献

为了探讨太极拳的身心调控作用,采用三个实验,通过分析演练太极拳(整体的调身)、实施太极拳式呼吸调控(调息)以及太极拳式自我调节放松(调心)前后的脑波变化、状态性焦虑特征,论证太极拳身心调控作用。实验一表明太极拳熟练者的α1、α2节律含有率均显著高于初学者,且熟练者的状态性焦虑显示持续性下降。实验二表明,实施太极拳式呼吸前后脑波均处于α2节律的优势状态。实验三表明,太极拳的意念调节放松后头部顶叶以及枕叶的α2节律含有量明显高于放松前,且肌电积分值明显减少。三个实验结果均显示在太极拳身心调控后状态性焦虑降低,脑波α2节律优势的现象,表明从脑波学初步证明太极拳的身心调控效果。 相似文献

The aim of this study was to identify the influence of prior knowledge of exercise duration on players’ pacing patterns during soccer small-sided games. Twenty semi-professional male soccer players participated in this study. In the first game scenario, players were not informed how long they would be required to play the small-sided game and the activity was terminated after 20 min (Unknown Condition). In the second game scenario, players were told that they would play the small-sided game for 10 min, but immediately after completing the 10-min game, they were asked to complete another 10 min (Partially Condition). In the third game scenario, players were instructed that they would play the small-sided game for 20 min and then they completed the 20-min game (Known Condition). The results presented a tendency of higher values in all performance variables in the [0′–10′] min compared with the [10′–20′] min. As the players’ previous knowledge about the tasks duration increased, the performance between two moments tended to be similar. Considering the entire 20-min game duration, the Partially Condition of the exercise was the most demanding condition. In conclusion, the knowledge of shorter durations of the exercise seems to lead to an increase of exercise duration demand, and longer exercise durations possibly tend to decrease differences between full knowledge and not knowing the exercise duration. 相似文献

Parental coviewing – the act of being present when a child is watching television – can influence the child’s cognitive processing and emotional reactions. This study investigated the role coviewing has on the child’s cognitive processing – which is evidenced by the phasic psychophysiological orienting response to three types of information: plot explicit, educational explicit, and implicit inference. An experiment was conducted that measured the heart rate of children (N?=?88; mean age?=?9.12 years) while watching messages either with or without a parent present in the room. It was predicted, and found, that coviewing leads to greater resource allocation to encoding the message – as indicated by phasic cardiac deceleration, and that information that required internal processing, such as plot explicit or implicit inferential content, leads to greater resources allocated to internal processing – as indicated by phasic cardiac acceleration. Implications for parental mediation strategies and educational television programming are given. 相似文献

Effectively regulating negative emotions is important for successful self-regulated learning. However, research has hardly examined which emotion regulation strategies benefit self-regulated learning. In an experimental study, it was examined whether positive reappraisal facilitates self-regulated learning by counterbalancing the depletion of self-control resources. Sixty-one university students engaged in either positive reappraisal or expressive suppression to regulate negative emotions induced by a film clip and then worked on a self-regulated learning task. Participants who engaged in positive reappraisal experienced more positive emotions after the film and had more self-control resources available than participants who used expressive suppression. Moreover, positive reappraisal increased skin conductance during emotion regulation, as compared to expressive suppression. Irrespective of emotion regulation type, positive emotions predicted post-film availability of self-control resources which was positively associated with subsequent self-regulated learning. The results demonstrate beneficial affective and resource-related consequences of positive reappraisal as well as its potential for fostering self-regulated learning. 相似文献

This article analyses the initiating role of the steel industry in educational selection by means of psychometric techniques used in the psycho-physiological laboratory associated with a vocational school in Luxembourg founded in 1914. It first considers the origins of, and initial meanings bestowed upon, this first (and perhaps also last) Luxembourg Laboratory of Psychophysiology. Second, it investigates whether and, if so, to what extent psychometric techniques developed in this laboratory for vocational orientation were used strategically to foster an ethic of individual harmony by means of objectified observation and categorisation of the aptitude. What hidden agendas underpinned the industry’s rhetoric regarding the rebirth of the individual and the empowerment of personal vocation through science-oriented processes like quantification, measurement and rational assessment? Did such rhetoric legitimise the industry’s self-image as a privileged force in structuring the social fabric as well as individual lives? 相似文献

Immersive environments induced by audiovisual stimuli are hypothesised to facilitate the control of movements and ameliorate fatigue-related symptoms during exercise. The objective of the present study was to investigate the effects of pleasant and unpleasant audiovisual stimuli on perceptual and psychophysiological responses during moderate-intensity exercises performed on an electromagnetically braked cycle ergometer. Twenty young adults were administered three experimental conditions in a randomised and counterbalanced order: unpleasant stimulus (US; e.g. images depicting laboured breathing); pleasant stimulus (PS; e.g. images depicting pleasant emotions); and neutral stimulus (NS; e.g. neutral facial expressions). The exercise had 10 min of duration (2 min of warm-up?+?6 min of exercise?+?2 min of warm-down). During all conditions, the rate of perceived exertion and heart rate variability were monitored to further understanding of the moderating influence of audiovisual stimuli on perceptual and psychophysiological responses, respectively. The results of the present study indicate that PS ameliorated fatigue-related symptoms and reduced the physiological stress imposed by the exercise bout. Conversely, US increased the global activity of the autonomic nervous system and increased exertional responses to a greater degree when compared to PS. Accordingly, audiovisual stimuli appear to induce a psychophysiological response in which individuals visualise themselves within the story presented in the video. In such instances, individuals appear to copy the behaviour observed in the videos as if the situation was real. This mirroring mechanism has the potential to up-/down-regulate the cardiac work as if in fact the exercise intensities were different in each condition. 相似文献
