Affective Responses to Increasing- and Decreasing-Intensity Resistance Training Protocols.

This study compared the effects of an increasing-intensity (UP) and a decreasing-intensity (DOWN) resistance training protocol on affective responses across six training sessions. Novice participants (Mage 43.5 ± 13.7 years) were randomly assigned to UP (n = 18) or DOWN (n = 17) resistance training groups. Linear mixed-effects models showed that the evolution of affective valence within each training session was significantly moderated by the group (b = -0.45, p ≤ .001), with participants in the UP group reporting a decline in pleasure during each session (b = -0.82) and the DOWN group reporting an improvement (b = 0.97; ps < .001). Remembered pleasure was significantly higher in the DOWN group compared to the UP group (b = 0.57, p = .004). These findings indicate that a pattern of decreasing intensity throughout a resistance exercise session can elicit more positive affective responses and retrospective affective evaluations of resistance training.

Listening to Fast-Tempo Music Improves Physical Performance in Recreational Swimmers.

Purpose: To determine whether swimming while listening to fast (140 bpm) or moderate tempo (120 bpm) music enhances physical performance compared to a non-music condition. Methods: Sixteen healthy university students (21.5 ± 2.3 years) with a minimum of one year of experience swimming front crawl were recruited. All completed four testing sessions. In the first session, a graded exercise treadmill test was performed to establish baseline fitness. The next three visits were at the swimming pool and participants were asked to swim as far as possible in 12-minutes (i.e., Swimming Cooper Test) under each of three randomly assigned conditions: 120 bpm (M120), 140 bpm (M140) and a non-music condition (NM). Results: No significant differences were found between conditions for either heart rate (p > .05) or rating of perceived exertion (p > .05). However, differences were found on distance covered (p = .014) between M120 (305.7 ± 19.7 m) and M140 (321.2 ± 19.4 m; p = .035), and on stroke frequency (p = .009) between M120 (48.4 ± 1.8) and M140 (51.6 ± 1.9; p = .028). Conclusion: These results suggest that distance covered and the frequency of strokes per minute were greater when participants were exposed to fast tempo music (M140) compared to moderate tempo music (M120) and a non-music condition (NM) in a 12-minute swimming test.

Physical activity and mental well-being under COVID-19 lockdown: a cross-sectional multination study.

BACKGROUND: COVID-19 lockdowns have reduced opportunities for physical activity (PA) and encouraged more sedentary lifestyles. A concomitant of sedentariness is compromised mental health. We investigated the effects of COVID-19 lockdown on PA, sedentary behavior, and mental health across four Western nations (USA, UK, France, and Australia). METHODS: An online survey was administered in the second quarter of 2020 (N = 2541). We measured planned and unplanned dimensions of PA using the Brunel Lifestyle Physical Activity Questionnaire and mental health using the 12-item General Health Questionnaire. Steps per day were recorded only from participants who used an electronic device for this purpose, and sedentary behavior was reported in hours per day (sitting and screen time). RESULTS: In the USA and Australia samples, there was a significant decline in planned PA from pre- to during lockdown. Among young adults, Australians exhibited the lowest planned PA scores, while in middle-aged groups, the UK recorded the highest. Young adults exhibited the largest reduction in unplanned PA. Across nations, there was a reduction of ~ 2000 steps per day. Large increases in sedentary behavior emerged during lockdown, which were most acute in young adults. Lockdown was associated with a decline in mental health that was more pronounced in women. CONCLUSIONS: The findings illustrate the deleterious effects of lockdown on PA, sedentary behavior, and mental health across four Western nations. Australian young and lower middle-aged adults appeared to fare particularly badly in terms of planned PA. The reduction in steps per day is equivalent to the non-expenditure of ~ 100 kcal. Declines in mental health show how harmful lockdowns can be for women in particular.

Prime Movers: Effects of Subliminal Primes, Music, and Music Video on Psychological Responses to Exercise.

BACKGROUND: Priming is a process in which exposure to a stimulus activates relevant mental representations that are given increased weight in subsequent judgment tasks. Affective primes can influence affective evaluations and associations. Such influence has meaningful implications for the promotion of exercise behavior, yet there is scant research on priming effects in exercise settings. PURPOSE: The purpose of the present pair of studies was to examine the efficacy of music (M), music video (MV), and music video with affective primes (PRIME) in modulating psychological responses during and immediately following an exercise bout among two distinct populations. METHODS: In Study 1, physically active participants completed a brisk walking task on a treadmill under four conditions: M, MV, PRIME, and control. Affective valence and rating of perceived exertion (RPE) were assessed during exercise and remembered/forecasted pleasure was measured immediately following each exercise bout. In Study 2, largely inactive and overweight participants completed a brisk walking task on a treadmill under two conditions: MV and PRIME. Affective valence was assessed during exercise, while exercise enjoyment and remembered/forecasted pleasure were assessed postexercise. RESULTS: In Study 1, PRIME yielded more positively valenced affect, remembered/forecasted pleasure, and lower RPE when compared to the other conditions (MCohen's d for all DVs = 0.91). In Study 2, PRIME elicited more positively valenced affect, greater enjoyment, and enhanced remembered/forecasted pleasure when compared to MV (MCohen's d for all DVs = 0.64). CONCLUSIONS: Subliminal primes embedded in music video can elicit positive changes in psychological responses during and immediately following exercise.

Increasing the Pleasure and Enjoyment of Exercise: A Novel Resistance-Training Protocol.

This study was designed to test the effect of an increasing- (UP) or decreasing-intensity (DOWN) resistance-training (RT) protocol on the pleasure and enjoyment of RT. The participants (N = 40; mean age = 35.0 ± 9.2 years) completed two RT sessions comprising 3 × 10 repetitions of six exercises. In the UP condition, load progressively increased from 55% to 75% of 1-repetition maximum, while in the DOWN condition, this pattern was reversed (i.e., 75-55% 1-repetition maximum). The DOWN condition resulted in more overall pleasure compared with UP and a slope of increasing pleasure, while the UP condition resulted in decreasing pleasure. Enjoyment of RT, postexercise pleasure, and remembered pleasure were all significantly greater for DOWN compared with UP (all ps > .01). These findings suggest that decreasing RT intensity throughout an exercise bout can elicit a positive slope of pleasure and enhance affective evaluations of exercise.

In the Zone: An Exploration of Personal Characteristics Underlying Affective Responses to Heavy Exercise.

Positive affective responses to exercise have been linked to longer-term adherence. The dual-mode model indicates that affective responses during heavy exercise (between the ventilatory threshold and the respiratory compensation point) are subject to interindividual variability (zone of response variability). Participants (N = 48) completed measures to assess personal characteristics prior to a graded exercise test. Responses to the Feeling Scale were recorded during the graded exercise test and subsequently used to group participants as either negative responders or neutral/positive responders to heavy exercise. Discriminant function analysis was applied, and a significant weighted linear composite predicted affective response. Preference for exercise intensity and sex were significant predictors (p = .003). Negative responders had lower preference scores and were more likely to be men. The combination of these two variables successfully predicted group membership 71% of the time. Individual differences appear relevant when examining affective responses to heavy exercise.

The Diabeates Project: Perceptual, Affective and Psychophysiological Effects of Music and Music-Video in a Clinical Exercise Setting.

OBJECTIVES: The purpose of this study was to examine the effects of music and music-video on perceptual (attentional focus, rated perceived exertion), affective (affective valence and enjoyment) and psychophysiological (blood glucose, heart rate) variables in outpatients attending a diabetes exercise clinic. METHODS: Participants were 24 females (age = 66.0 ± 8.5 years) enrolled in a supervised exercise program for people with diabetes. They engaged in mixed-modality exercise sessions that included a standardized combination of flexibility, aerobic and resistance activities under conditions of music, music-video and control. RESULTS: Analyses revealed a main effect of condition on attentional focus and affect during aerobic exercise only. The music-video condition elicited the highest level of attentional dissociation, while affective valence was more positive in the 2 experimental conditions when compared to control. Rated perceived exertion and heart rate did not differ across conditions. Measures of exercise enjoyment indicated a main effect of condition wherein scores were higher with the music-video condition when compared to control. There was an acute glucose-lowering effect of exercise in all conditions. CONCLUSIONS: Results lend support to the notion that auditory and visual stimuli can enhance affective responses to exercise in a clinical setting. This may have meaningful implications for adherence, given the link between affective judgements and future behaviour in an exercise context.

The Effects of Mental Imagery with Video-Modeling on Self-Efficacy and Maximal Front Squat Ability.

This study was designed to assess the effectiveness of mental imagery supplemented with video-modeling on self-efficacy and front squat strength (three repetition maximum; 3RM). Subjects (13 male, 7 female) who had at least 6 months of front squat experience were assigned to either an experimental (n = 10) or a control (n = 10) group. Subjects' 3RM and self-efficacy for the 3RM were measured at baseline. Following this, subjects in the experimental group followed a structured imagery protocol, incorporating video recordings of both their own 3RM performance and a model lifter with excellent technique, twice a day for three days. Subjects in the control group spent the same amount of time viewing a placebo video. Following three days with no physical training, measurements of front squat 3RM and self-efficacy for the 3RM were repeated. Subjects in the experimental group increased in self-efficacy following the intervention, and showed greater 3RM improvement than those in the control group. Self-efficacy was found to significantly mediate the relationship between imagery and front squat 3RM. These findings point to the importance of mental skills training for the enhancement of self-efficacy and front squat performance.

See hear: psychological effects of music and music-video during treadmill running.

BACKGROUND: There is a paucity of work addressing the distractive, affect-enhancing, and motivational influences of music and video in combination during exercise. PURPOSE: We examined the effects of music and music-and-video on a range of psychological and psychophysical variables during treadmill running at intensities above and below ventilatory threshold (VT). METHODS: Participants (N = 24) exercised at 10 % of maximal capacity below VT and 10 % above under music-only, music-and-video, and control conditions. RESULTS: There was a condition × intensity × time interaction for perceived activation and state motivation, and an intensity × time interaction for state attention, perceived exertion (RPE), and affective valence. The music-and-video condition elicited the highest levels of dissociation, lowest RPE, and most positive affective responses regardless of exercise intensity. CONCLUSIONS: Attentional manipulations influence psychological and psychophysical variables at exercise intensities above and below VT, and this effect is enhanced by the combined presentation of auditory and visual stimuli.

Moderating influence of dominant attentional style and exercise intensity on responses to asynchronous music.

We examined independent and combined influences of asynchronous music and dominant attentional style (DAS) on psychological and psychophysical variables during exercise using mixed methods. Participants (N = 34) were grouped according to DAS and completed treadmill runs at three intensities (low, moderate, high) crossed with three music conditions (motivational, oudeterous, no-music control). State attentional focus shifted from dissociative to associative with increasing intensity and was most aligned with DAS during moderate-intensity exercise. Both music conditions facilitated dissociation at low-to-moderate intensities. At high exercise intensity, both music conditions were associated with reduced RPE among participants with an associative DAS. Dissociators reported higher RPE overall during moderate and high intensities. Psychological responses were most positive in the motivational condition, followed by oudeterous and control. Findings illustrate the relevance of individual differences in DAS as well as task intensity and duration when selecting music for exercise.
