The effects of Latino Dance intervention on academic and general self-efficacy with left-behind children: An experimental study in China.

Introduction: Although there is considerable research indicating that physical exercise and dance can strengthen children's self-efficacy, and children's self-efficacy can predict students' academic achievement at a wide range of academic levels. Few studies have been conducted using Latino Dance to improve self-efficacy in Left-Behind Children (LBC), especially the two aspects of student academic self-efficacy and general self-efficacy, while the mediator role of self-esteem between student academic self-efficacy and general self-efficacy has been less explored in previous research. Methods: This study proposed to examine Latino Dance interventions to improve general self-efficacy and students' academic self-efficacy among LBC students in rural areas to boost students' academic performance, and the research team hypothesised that general self-efficacy, students' academic self-efficacy and self-esteem would improve following the intervention and that outcomes will have a significant positive correlation as students' self-esteem can mediate both their academic self-efficacy and their general self-efficacy. Dates were collected from 305 LBCs children (160 boys and 145 girls) from 6 left-behind schools in Hunan province, China. Ralf Schwarzer's general self-efficacy scale, Morgan-Jinks Student academic Self-Efficacy Scale, and Rosenberg's self-esteem scale were administered to LBCs between September 2020 and January 2022. Results: The results revealed that the Latino Dance intervention significantly increased the LBC student' academic self-efficacy and general self-efficacy, which also involved a positive effect on the three sub-dimensions (talent, context, and effort) of students' academic self-efficacy. Further, multiple linear regression analysis confirmed that self-esteem (positive esteem/self-deprecation) acted as a partial mediator between student academic self-efficacy and general self-efficacy; perceived self-esteem played a mediating role between them. Discussion: This study filled a gap in the literature concerning the psychological reinforcement effect of Latino Dance on LBC groups and demonstrated that Latino Dance improved the student' academic self-efficacy and general self-efficacy among the LBCs. Our results suggest that Latino Dance can be beneficial for LBC in school by including Latino Dance in Physical Education or Art courses and improving students' self-esteem may lead to an increase in student academic self-efficacy as well as general self-efficacy, thereby improving and enhancing the learning of LBCs.

The Influence of Caffeine Expectancies on Simulated Soccer Performance in Recreational Individuals.

Caffeine (CAF) has been reported to improve various facets associated with successful soccer play, including gross motor skill performance, endurance capacity and cognition. These benefits are primarily attributed to pharmacological mechanisms. However, evidence assessing CAF's overall effects on soccer performance are sparse with no studies accounting for CAF's potential psychological impact. Therefore, the aim of this study was to assess CAF's psychological vs. pharmacological influence on various facets of simulated soccer performance. Utilising a double-dissociation design, eight male recreational soccer players (age: 22 ± 5 years, body mass: 78 ± 16 kg, height: 178 ± 6 cm) consumed CAF (3 mg/kg/body mass) or placebo (PLA) capsules, 60 minutes prior to performing the Loughborough Intermittent Shuttle Test (LIST) interspersed with a collection of ratings of perceived exertion (RPE), blood glucose and lactate, heart rate and performing the Loughborough Soccer Passing Test (LSPT). Whole-body dynamic reaction time (DRT) was assessed pre- and post- LIST, and endurance capacity (TLIM) post, time-matched LIST. Statistical analysis was performed using IBM SPSS (v24) whilst subjective perceptions were explored using template analysis. Mean TLIM was greatest (p < 0.001) for synergism (given CAF/told CAF) (672 ± 132 s) vs. placebo (given PLA/told PLA) (533 ± 79 s). However, when isolated, TLIM was greater (p = 0.012) for CAF psychology (given PLA/told CAF) (623 ± 117 s) vs. pharmacology (given CAF/told PLA) (578 ± 99 s), potentially, via reduced RPE. Although DRT performance was greater (p = 0.024) post-ingestion (+5 hits) and post-exercise (+7 hits) for pharmacology vs. placebo, psychology and synergism appeared to improve LSPT performance vs. pharmacology. Interestingly, positive perceptions during psychology inhibited LSPT and DRT performance via potential CAF over-reliance, with the opposite occurring following negative perceptions. The benefits associated with CAF expectancies may better suit tasks that entail lesser cognitive-/skill-specific attributes but greater gross motor function and this is likely due to reduced RPE. In isolation, these effects appear greater vs. CAF pharmacology. However, an additive benefit may be observed after combining expectancy with CAF pharmacology (i.e. synergism).

The Influence of Caffeine Expectancies on Sport, Exercise, and Cognitive Performance.

Caffeine (CAF) is widely consumed across sport and exercise for its reputed ergogenic properties, including central nervous stimulation and enhanced muscular force development. However, expectancy and the related psychological permutations that are associated with oral CAF ingestion are generally not considered in most experimental designs and these could be important in understanding if/how CAF elicits an ergogenic effect. The present paper reviews 17 intervention studies across sport, exercise, and cognitive performance. All explore CAF expectancies, in conjunction with/without CAF pharmacology. Thirteen out of 17 studies indicated expectancy effects of varying magnitudes across a range of exercise tasks and cognitive skills inclusive off but not limited to; endurance capacity, weightlifting performance, simple reaction time and memory. Factors, such as motivation, belief, and habitual CAF consumption habits influenced the response. In many instances, these effects were comparable to CAF pharmacology. Given these findings and the lack of consistency in the experimental design, future research acknowledging factors, such as habitual CAF consumption habits, habituated expectations, and the importance of subjective post-hoc analysis will help to advance knowledge within this area.
