Trial Summary
What is the purpose of this trial?Many athletes anecdotally report modifying their nutritional intake before competition in order to avoid gut problems, but no studies have evaluated whether emotional state impacts tolerance to pre-exercise feeding. Therefore, this study will use movie clips (stressful, horror, and funny/amusing) to induce different mood states and emotions, which will be followed by ingestion of food before endurance running on a treadmill. In addition, metabolic and physiologic responses to mood induction will be evaluated.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications.
What data supports the effectiveness of the treatment Funny/Amusing Video Clips, Horror/Scary Video Clips, Thrilling/Suspenseful Video Clips, Stressful Video Clips, Emotional Stimulation?
Research shows that audiovisual stimuli, like video clips, can improve mood and reduce fatigue during exercise, making it more enjoyable. Additionally, emotions that create high energy, such as those from thrilling or scary videos, can enhance exercise performance, especially in individuals who are less active.
12345Is it safe to use emotional video clips to influence exercise performance?
Research involving emotional video clips, such as funny or scary videos, shows they can influence exercise experiences by affecting mood and motivation. However, there is no specific mention of safety concerns, suggesting they are generally safe for use in humans.
12467How does the treatment for emotional states' influence on pre-exercise feeding tolerance differ from other treatments?
This treatment is unique because it explores how emotional states affect tolerance to eating before exercise, focusing on the psychological and emotional aspects rather than just the physical or nutritional components. Unlike standard treatments that might focus solely on diet or exercise, this approach considers the emotional triggers and responses that can influence pre-exercise eating habits.

Effects of audiovisual stimuli on psychological and psychophysiological responses during exercise in adults with obesity. [2019]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.
Affective Response During Real-World Physical Activity as an Intervention Mediator. [2023]Some people experience pleasure during physical activity, whereas it can be unpleasant for others. Modifying affective responses during physical activity in real-world situations may be an intervention strategy for increasing physical activity. This article follows an experimental medicine framework to summarize evidence identifying, assessing, and influencing affective response during real-world physical activity to inform interventions targeting this mediating mechanism.
Can Simulated Green Exercise Improve Recovery From Acute Mental Stress? [2020]This exploratory study enhances previous research into green exercise and addresses a gap in the research by exploring the contribution of individual and combined senses in the recovery of mood and stress after a psychological stressor, whilst rigorously controlling exercise intensity. The hypotheses were: (i) recovery of mood and stress from a state of psychological stress would be greater following simulated green exercise compared to rest, (ii) green exercise would facilitate better recovery than exercise alone, (iii) these effects would remain 10 min following intervention, and (iv) visual stimuli alone would enhance recovery from a state of psychological stress compared to sound. Fifty participants were randomly assigned to one of five groups: REST, exercise, exercise with nature sounds, exercise with nature visual and exercise with nature sound and visual. An initial visit to obtain predicted peak power output values and to familiarize participants with the equipment being used was followed by a second visit, where participants experienced one test condition. Baseline measures of heart rate, blood pressure, total mood disturbance (TMD), and perceived stress were taken, before participants completed a stressor based on the Trier Social Stress test. Measures of heart rate and blood pressure were recorded in the last 30 s of the stressor to assess efficacy of the stressor. Immediately post stressor, measures of mood and perceived stress were taken followed by the intervention assigned (one of five described above). Measures of mood and perceived stress were taken again immediately post intervention and 10 min post intervention. Results showed that green exercise improved mood and stress scores more than exercise alone or REST. For both TMD and perceived stress, improvements in all simulated nature conditions were significantly improved compared to REST or exercise alone immediately post intervention. There were no significant changes 10 min post intervention in either mood or perceived stress compared to immediately post intervention values in any of the groups. This study suggests that environmental exercise settings including nature sounds, visual or both combined should be considered as important in the use of exercise as a therapeutic activity or recovery from acute psychological stress.
When Anger Motivates: Approach States Selectively Influence Running Performance. [2023]Emotional states are thought to influence athletic performance. Emotions characterized by high arousal enhance exercise performance. Extant research has focused on the valence and arousal dimensions of emotions, but not whether the motivational dimension (the extent to which the emotion engenders approach or avoidance behaviors) influences exercise performance. Two studies aimed to determine whether films and music chosen to induce approach- (i.e., anger), avoidance- (i.e., fear), and neutral-oriented emotions would successfully induce their intended emotional states (Study 1) and whether anger and fear emotion inductions would influence 2-mile time trial performance (Study 2). In Study 1, the films and music successfully induced their intended emotions. In Study 2, run time and perceived level of exertion did not differ between emotions across all participants or among faster running participants per a median split. However, among slower running participants, the anger induction increased the 2-mile running speed relative to the neutral induction. These findings suggest that emotions eliciting approach-related motivational states may improve exercise performance, particularly in slower runners.
Effect of the Verbal Encouragement on Psychophysiological and Affective Responses during Small-Sided Games. [2021]Verbal encouragement (VE) is considered as external motivation provided by physical education teacher. For this reason, this study aimed to examine the effects of VE on psychophysiological and affective responses during small-sided games (SSG). Sixteen male school students (age: 17.37 ± 0.48 years) completed four sessions of a 4-a-side SSG. Two sessions occurred with VE (SSGE), and two sessions did not include VE (SSGNE). Heart rate was continuously recorded, and rating of perceived exertion (RPE) and blood lactate concentration ([La]b) were measured after each training session. Physical enjoyment was assessed after each protocol. Mood state was recorded before and after each training session using the profile of mood-state. HR max, [La]b, RPE, Physical enjoyment, and vigor were higher in SSGE compared to SSGNE (all, p < 0.001). The SSGE and SSGNE resulted in a decreased total mood disturbance (TMD) (p = 0.001, ES = 0.60; p = 0.04, ES = 0.33, respectively) and tension (p < 0.001, ES = 0.91; p = 0.004, ES = 0.47, respectively), and the vigor was increased after the SSGE (p < 0.001, ES = 0.76). SSGE and SSGNE induce similar improvement in TMD and tension. However, SSGE induced higher physiological responses, RPE, enjoyment, and positive mood than SSGNE. Physical education teachers could use VE during specific soccer sessions to improve physical aspects, enjoyment, and mood in participants.
Physical Activity Increases after an Affectively Arousing Daily Life Event. [2020]Evidence that structured physical activity can help to regulate affective state has spurred interest in identifying associations between unstructured physical activity and affective states during daily life. The present study examined whether stressful daily life situations that elicit affective arousal also elicit increased physical activity in the form of restless movement. The study compared the physical activity of professors (n = 25) after presenting a classroom lecture to their physical activity at the same time of day on a non-lecture workday. The expectation was that lecturing would increase affective arousal, leading to greater restless movement following the lecture compared to the non-lecture control day. The study assessed subjective arousal to confirm that arousal was higher during the lecture. The primary outcome measures were actigraphy-measured standing and stepping times and number of steps and posture transitions. Results indicate that energetic and tense arousal were higher during the lecture than during the control period. Mean (±SE) up time (standing and stepping) for the 1st minute of the 20 minute post-lecture period was double that of the last minute (32.8 ± 5.73 s to 16.5 ± 5.41 s), while it remained low throughout the comparison period on the control day (p = 0.01). Subjects also took more steps (p = 0.006) and engaged in more transitions between sitting and standing (p = 0.02) after the lecture than after the control period. These results support the conclusion that stressful daily life situations that elicit affective arousal also elicit increased physical activity in the form of restless movement and suggest that affective responses to stressful situations may be important determinants of physical activity during daily life.
Experimental investigation of exercise-related hedonic responses to preferred and imposed media content. [2020]Background: We evaluated the differential influence of preferred versus imposed media selections on distinct hedonic responses to an acute bout of treadmill walking. Methods: Twenty university students were recruited for this [160 person-visit] laboratory experiment, which employed a within-subject, counter-balanced design. Participants were exposed to 8 experimental conditions, including (1) Exercise Only, (2) Texting Only, (3) Preferred Phone Call, (4) Imposed Phone Call, (5) Preferred Music Playlist, (6) Imposed Music Playlist, (7)Preferred Video and (8) Imposed Video. During each visit (except Texting Only), participants completed a 10-minute bout of walking on the treadmill at a self-selected pace. Walking speed was identical for all experimental conditions. Before, at the midpoint of exercise, and post-exercise, participants completed the Feeling Scale (FS) and the Felt Arousal Scale (FAS) to measure acute hedonic response. The Affective Circumplex Scale was administered pre-exercise and post-exercise. Results: Significant pre-post change scores were observed for happy (Imposed Call: P=0.05;Preferred Music: P=0.02; Imposed Video: P=0.03), excited (Exercise Only: P=0.001; PreferredVideo: P=0.01; Imposed Video: P=0.03), sad (Preferred Music: P=0.05), anxious (ExerciseOnly: P=0.05; Preferred Video: P=0.01), and fatigue (Exercise Only: P=0.03; Imposed Video:P=0.002). For the FS all change scores were statistically significant from pre-to-mid and pre-topost (P<0.05). Conclusion: This experiment provides strong evidence that entertaining media platforms substantively influences hedonic responses to exercise. Implications of these findings are discussed.
Effect of Fed State on Self-selected Intensity and Affective Responses to Exercise Following Public Health Recommendations. [2023]Nutritional status has numerous effects on exercise metabolism and psychological responses. The effect of fed state on changes in affective valence; however, are unknown. Thus, the present study examined how fed state influenced self-selected exercise intensity, affective responses during exercise, and exercise enjoyment when exercise was completed following physical activity guidelines for public health. In a repeated-measures crossover design, 25 recreationally active men and women (age and BMI = 22.0 ± 2.0 yr and 24.3 ± 3.3 kg/m2) performed a single 30 min session of treadmill exercise at a Rating of Perceived Exertion (RPE) equal to 13 on the Borg 6-20 scale following an overnight fast (FAST) or 30 minutes after a small meal (FED). Affective valence was recorded every 3 minutes during exercise. Heart rate and gas exchange data were measured continuously using a metabolic cart, blood glucose and blood lactate concentration were measured pre/post-exercise, and enjoyment was measured 15 minutes post-exercise. There was no effect of condition on affective valence, enjoyment, or self-selected intensity (all p>0.05). However, pre-exercise blood glucose was higher in FED pre-exercise, but higher post-exercise in FAST (p<0.05). Blood lactate concentration was also higher in FAST (p<0.05). Our results reveal minimal effects of a small, high-carbohydrate pre-exercise meal on in-task and post-task affective responses, exercise enjoyment, and self-selected intensity. These data suggest that an overnight fast does not alter affective valence or reduce enjoyment of continuous exercise.
An enjoyable distraction during exercise augments the positive effects of exercise on mood. [2021]The hypothesis that an enjoyable distraction during exercise will augment the intensity of positive mood post-exercise was tested. A sample of 84 undergraduate students rated their mood and arousal before and after a standardized exercise, which consisted of walking on a treadmill at a pace of 3.6 mph for 10 minutes. During the work out session, participants watched the same television show, which they previously rated as enjoyable, or not enjoyable. As added controls, a third group exercised with no distraction (the TV was turned off); a fourth group did not exercise, but watched the television show. The results showed that exercise alone was sufficient to increase pleasant mood (95% CI 0.61, 1.46) and that including an enjoyable distraction during exercise significantly augmented pleasant mood compared to all other groups (95% CI 1.58, 2.99; R(2) = 0.29). These results show that the enjoyment of a distraction is a key factor that can augment the intensity of positive mood following exercise. Key pointsThe hypothesis that an enjoyable distraction during exercise will augment the intensity of positive mood post-exercise was tested.The results support this hypothesis by showing for the first time that while exercise alone was sufficient to increase the intensity of positive mood; combining exercise with an enjoyable distraction resulted in significantly greater increases in pleasant mood compared to exercise alone.Accounting for the enjoyment of a distraction type in future studies can increase the sensitivity of research designs used to detect changes in positive mood post-exercise.
Mitigation of the effects of emotional eating on sweets consumption by treatment-associated self-regulatory skills usage in emerging adult and middle-age women with obesity. [2021]An urge to eat in response to negative emotions or mood (emotional eating) is associated with an overconsumption of unhealthy foods such as sweets. Propensities for emotional eating is most prevalent in women, but its effects might differ by age. Within behavioral obesity treatments, it is unclear whether learned self-regulatory skills mitigate the effects of emotional eating susceptibilities on sweets intake, or if expected exercise-induced mood improvements affect the emotional eating-sweets intake relationship. Emerging adult (18-25 years-of-age; n = 43) and middle-age (45-65 years-of-age; n = 79) women with obesity participating in the same cognitive-behavioral treatment that emphasized exercise prior to eating-behavior changes were assessed on levels of propensities for emotional eating, self-regulatory skills usage, mood, and intake of sweets. There were overall significant improvements in self-regulation for eating, overall mood, and daily intake of sweets; with a significantly greater reduction in sweets in the emerging adult women. Self-regulation for eating at Month 3 significantly mediated the prediction of sweets intake at Month 6 by overall emotional eating and emotional eating related to depression. When dimensions of mood (i.e., total negative mood, depression, anxiety, anger) at Month 3 were entered into the models as possible moderators of relationships between a corresponding dimension of emotional eating and sweets intake, anxiety was found to be a significant moderator. Because sweets intake was affected by age, it should be considered in behavioral obesity interventions. Findings suggested advantages of fostering self-regulatory skills and reductions in anxiety, possibly through supported exercise, to mitigate unhealthy eating behaviors associated with propensities for emotional eating.
