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

β-hydroxy-β-methylbutyrate (calcium: HMB-Ca and free acid: HMB-FA) and α-hydroxyisocaproic acid (α-HICA) are leucine metabolites that have been proposed to improve body composition and strength when combined with resistance exercise training (RET). In this double-blind randomized controlled pragmatic trial, we evaluated the effects of off-the-shelf supplements: α-HICA, HMB-FA and HMB-Ca, on RET-induced changes in body composition and performance. Forty men were blocked randomized to receive α-HICA (n?=?10, fat-free mass [FFM]?=?62.0?±?7.1?kg), HMB-FA (n?=?11, FFM?=?62.7?±?10.5?kg), HMB-Ca (n?=?9, FFM?=?65.6?±?10.1?kg) or placebo (PLA; n?=?10, FFM?=?64.2?±?5.7?kg). The training protocol consisted of a whole-body resistance training routine, thrice weekly for 8 weeks. Body composition was assessed by dual-energy x-ray absorptiometry (DXA) and total body water (TBW) by whole-body bioimpedance spectroscopy (BIS), both at baseline and at the end of weeks 4 and 8. Time-dependent changes were observed for increase in trunk FFM (p?0.05). No statistically significant between-group or group-by-time interactions were observed. Supplementation with HMB (FA and Ca) or α-HICA failed to enhance body composition to a greater extent than placebo. We do not recommend these leucine metabolites for improving body composition changes with RET in young adult resistance trained men. 相似文献

High Intensity Interval Training (HIIT) can be performed with different effort to rest time-configurations, and this can largely influence training responses. The purpose of the study was to compare the acute physiological responses of two HIIT and one moderate intensity continuous training (MICT) protocol in young men. A randomised cross-over study with 10 men [age, 28.3?±?5.5years; weight, 77.3?±?9.3?kg; height, 1.8?±?0.1?m; peak oxygen consumption (VO2peak), 44?±?11?mL.kg?1.min?1]. Participants performed a cardiorespiratory test on a treadmill to assess VO2peak, velocity associated with VO2peak (vVO2peak), peak heart rate (HRpeak) and perceived exertion (RPE). Then participants performed three protocols equated by distance: Short HIIT (29 bouts of 30s at vVO2peak, interspersed by 30s of passive recovery, 29?min in total), Long HIIT (3 bouts of 4?min at 90% of vVO2peak, interspersed by 3?min of recovery at 60% of vVO2peak, 21?min in total) and MICT (21?min at 70% of vVO2peak). The protocols were performed in a randomised order with ≥48 h between them. VO2, HRpeak and RPE were compared. VO2peak in Long HIIT was significantly higher than Short HIIT and MICT (43?±?11 vs 32?±?8 and 37?±?8?mL.kg?1.min?1, respectively, P?0.05), as well as peak HR (181?±?10 vs 168?±?8 and 167?±?11, respectively, P?0.05), and RPE (17?±?4 vs 14?±?4 and 15?±?4, respectively, P?0.05), with no difference between Short HIIT and MICT. In conclusion, Long HIIT promoted higher acute increases in VO2, HR and RPE than Short HIIT and MICT, suggesting a higher demand on the cardiorespiratory system. Short HIIT and MICT presented similar physiologic and perceptual responses, despite Short HIIT being performed at higher velocities. 相似文献

A sport-specific measure of moral disengagement was developed in 2 studies. In Study 1, a 59-item questionnaire was developed and tested with 308 athletes from 5 team sports. A series of confirmatory factor analyses (CFA) testing different models suggested the model that best fitted the data had 6 first-order factors that could be represented by 1 second-order factor. Study 2 involved 305 athletes from the same 5 sports. CFA confirmed the 6-factor, second-order structure for the final 32-item measure. Results from Study 2 supported the construct validity of the scale, providing evidence for the factorial, concurrent, convergent, and discriminant validity. The Moral Disengagement in Sport Scale (MDSS) is proposed as a valid and reliable measure of moral disengagement for use in the sport context. 相似文献

When cynical distance and ironic posturing have become the prevalent means of relating to public life, political humour is no longer considered subversive. It has been argued that both in Russia and the United States, ideology has co-opted satire, meaning that citizens can consume outrage passively through various satirical media products, thereby displacing outrage and abstaining from more active forms of resistance. This articles explores the twenty-first century potential of irony and cynicism to disrupt and subvert through parody, be it in the form of political satire or ironic protest, examining how similar paradigms are expressed across different geographical contexts. 相似文献

ABSTRACTAlthough sports heritage is increasingly recognized as a potential catalyst of tourism, heritage sporting events (HSEs) are still an emerging concept in the academic literature. Notions that associate sports events and heritage remain rare, and are usually analysed through the scope of nostalgia sport tourism. This can be partly explained by an inclination to associate the notion of heritage with conventional ideas about folklore and traditional culture. Through a constructivist approach of heritage, this contribution argues that contemporary sports events, which would generally have competition as their primary focus, might also be perceived as HSEs. A comprehensive framework, built on a multi-disciplinary literature review, is presented to show the process that transforms an initial resource (a sports event) into an accomplished resource (a HSE), which might represent a competitive advantage for the territory. A qualitative–comparative analysis is conducted among 24 sports events in the French-speaking part of Switzerland, to observe the configurations of HSEs and understand which characteristics are necessary for the perceptions of a sports event as a heritage good. Interestingly, this contribution shows that if the event needs to be sustainable in the territory to be perceived as a HSE, it is not sufficient. Indeed, a differentiation strategy should be set up to distinguish the event from other more or less similar events, to be perceived as an authentic feature of the territory by the local population. 相似文献

An experimental 2 (channel) × 2 (gender) × 3 (time) mixed factorial design (N = 159) was applied to test and compare how individual dimensions of intercultural sensitivity might be affected by two channels: a virtual environment (i.e., Second Life®) versus a Web environment. Using a modified version of Chen and Starosta's Intercultural Sensitivity Scale (ISS), the study sought to identify which of the five ISS dimensions played the most influential role in intercultural sensitivity outcomes: interaction enjoyment, interaction engagement, interaction confidence, interaction attentiveness, or respect for cultural differences. Results showed that one's willingness and effort toward understanding an intercultural interaction – interaction attentiveness – played the greatest and most statistically significant role in intercultural sensitivity outcomes, and that this effect was greatest within the virtual environment channel. Gender effects were also found, in which men experienced greater enjoyment but women expressed more attentiveness. 相似文献
