Effect of the presence of an aquarium in the waiting area on the stress, anxiety and mood of adult dental patients: A controlled clinical trial

Background Interaction with fish is known to reduce stress and anxiety in humans. Objective This trial evaluated the effect of an aquarium present in a geriatric dental clinic waiting-area (WA) on blood pressure (BP), heart-rate (HR), anxiety, and mood of waiting patients. Methods Participants were recruited into three groups: control (CG): WA without aquarium; partially-stocked aquarium (PSA): aquarium without fish; fully-stocked aquarium (FSA): aquarium with fish. BP and HR of the participants were recorded upon arrival and after 20-minutes of waiting, along with anxiety [State trait anxiety inventory (STAI-6)] and mood [Feeling scale (FS), Felt arousal scale (FAS)] scores. A purpose-built questionnaire evaluated the subjective assessment of the participants’ experience in the WA. ANOVA with repeated measures and nonparametric tests were used for statistical analysis (p<0.05). Results 392 patients (mean age: 65.07±16.9y) completed this trial. There was an effect of time on the BP [systolic: F(1, 120) = 44.82, p<0.001; diastolic: F(1, 120) = 25.10, p<0.001] and HR [F(1, 120) = 40.94, p<0.001]. No effect of groups on BP [systolic: F(1, 120) = 1.01, p = 0.32; diastolic: F(1, 120) = 0.01, p = 0.92] was revealed, but a decrease of HR [F(1, 120) = 21.59, p<0.001]. No effect of time*group on BP [systolic: F(1, 120) = 0.89, p = 0.35; diastolic: F(1, 120) = 0.31, p = 0.58], or HR [F(1, 120) = 1.04, p-0.31]. WA groups had no effects on the participants’ anxiety [H(2) = 2.76, p = 0.25], or mood [FS: H(2) = 2.28, p = 0.32; FAS: H(2) = 1.54, p = 0.46]. Patients rated FSA higher than others [H(2) = 20.98, p<0.001). Conclusions There was no influence of the presence of an aquarium on the patients’ blood pressure, heart rate, anxiety, or mood.

Evidence-based vs. social media based high-intensity interval training protocols: Physiological and perceptual responses

Objective High intensity interval training (HIIT) is a time-efficient exercise modality to improve cardiorespiratory fitness, and has recently been popularised by social media influencers. However, little is known regarding acute physiological and perceptual responses to these online protocols compared to HIIT protocols used within research. The aim was to investigate acute physiological, perceptual and motivational responses to two HIIT protocols popular on social media, and compare these to two evidence-based protocols. Methods Twenty-seven recreationally active (>1 exercise session /week) participants (Age: 22±3y, BMI: 24.3±2.4) completed a randomised cross-over study, whereby each participant completed four HIIT protocols, two already established in research (Ergo-60:60 (cycling 10x60s at 100%Wmaxwith 60s rest), BW-60:60 (body-weight exercises 10x60swith 60s rest)) and two promoted on social media (SM-20:10 (body-weight exercises 20x20swith 10s rest) and SM-40:20 (body-weight exercises 15x40s with 20s rest)). Blood lactate, heart rate (HR), feeling scale (FS), felt arousal scale (FSA), enjoyment and perceived competence were measured in response to each protocol. Results Significant differences were observed between BW-60:60 and SM-20:10 for the proportion of intervals meeting the ACSM high-intensity exercise criterion (>80% of HRmax) (BW-60:60 93±10%, SM-20:10 74±20%, P = 0.039) and change in lactate (BW-60:60 +7.8±3.7mmol/L, SM-20:10 +5.5±2.6mmol/L, P = 0.001). The percentage of time spent above the criterion HR was also significantly lower in SM-20:10 compared to all other protocols (Ergo-60:60 13.9±4.9min, BW-60:60 13.5±3.5min, SM-40:20 12.1±2.4min, SM-20:10 7.7±3.1, P<0.05). No differences were observed in lowest reported FS between protocols (P = 0.268), but FS decreased linearly throughout Ergo-60:60 and BW-60:60 (first vs. last interval P<0.05), but not in SM-20:10 or SM-40:20 (P>0.05). Enjoyment was higher upon completion of BW-60:60 compared to Ergo-60:60 and SM-40:20 (P<0.05). Conclusions This study shows that HIIT protocols available on social media offer an interesting real-world alternative for promoting exercise participation. Future studies should continue to investigate these highly popular and practical HIIT protocols.

Discomfort, pain and fatigue levels of 160 cyclists after a kinematic bike-fitting method: an experimental study

ObjectiveTo analyse rider’s subjective responses after a standardised bicycle ergonomic adjustment method.MethodsExperimental study of 160 healthy, amateur mountain bikers analysed previously and 30 days after a bike-fitting session. The main outcome measures were subjective comfort level (Feeling Scale, FEEL), fatigue (OMINI Scale) and pain (Visual Analogue Scale, VAS).ResultsAll variables demonstrated statistical significance between groups pre and post bike-fit session (p<0001). FEEL, OMNI and VAS-knee demonstrated large effect sizes (d=1.30; d=1.39 and d=0.86, respectively). VAS-hands, VAS-neck and VAS-back indicated moderate effect size (d=0.58; d=0.52 and d=0.43, respectively). VAS-groin and VAS-ankle indicated a small size effect (d=0.46 and d=0.43, respectively).ConclusionsOverall discomfort, fatigue and pain in healthy mountain biker adults improved according to all three scales. The major improvements in pain levels were detected on the knee, hands, back and neck compared with presession values. Groin and ankle pain had smaller improvements but were still significant. Future clinical trials should address the bias effects of this experimental study.

Inferiority feeling pada remaja panti asuhan: Bagaimana peranan konsep diri dan dukungan sosial?

Inferiority feeling in adolescents who live in orphanages needs attention because if left unchecked it can cause adolescents to lose their potential. This study intends to examine the role of self-concept and social support on inferiority feelings. Participants in this study were 71 teenagers who were taken purposively from seven orphanages in Surabaya. The research data were taken using the inferiority feeling scale (?=0.874), the self-concept scale (?=0.935), and the social support scale (?=0.938) which were compiled by the researcher himself. The results of data analysis using multiple regression analysis show that self-concept and social support simultaneously have a negative effect on inferiority feeling. Partially both variables also have a significant negative effect on inferiority feeling. The implication of this research is as a basis of reference for caregivers, counsellors or the community in paying attention to the psychological needs of orphaned youth.Keywords: Inferiority Feeling; Self-concept; Social support AbstrakInferiority feeling pada remaja yang tinggal di panti asuhan perlu mendapatkan perhatian sebab jika dibiarkan dapat menyebabkan remaja kehilangan potensi dirinya.

General Psychosocial Measures are Affected by the Situation Preceding Assessment: The ‘Arbitrary Distinction’ Between State and Trait Measures is Still Unresolved

General psychosocial measures are assumed to be stable over time. However, such measures may be affected by the situation preceding assessment. In this study 28 participants completed the WHO-5 Well-Being Index, the Subjective Happiness Scale, and the Life Orientation Test which are general measures, and the Positive Affect Negative Affect Schedule and the Feeling Scale which are state measures. Subsequently, the first part of ‘Mega Disasters Nagasaki The Forgotten Bomb’ documentary was presented to the participants. Following the intervention, they completed the same measures again. State measures of negative affect increased, feeling state decreased as expected, but retrospectively measured well-being as well as the index of optimism also decreased. There were large individual differences. The findings indicate that general measures, assumed to be stable over time, are influenced by the situation. Therefore, there is a need for reporting, as well as controlling, the events preceding their measurement. The implication of these findings is that hundreds of empirical results based on general or trait measures may be invalid if any event preceding their assessment had an emotional impact.

Results of a postural education program, with a gamified intervention vs traditional intervention

The teaching methodology adopted by teachers can influence the levels of participation and learning of students. The main goal of this study was to compare the effect of two intervention programs of postural education according to the used methodology. A total of 36 students (19 girls and 17 boys) in the 1st year of high school participated in the study. In the first intervention program a gamified methodology was applied, while in the second one a traditional methodology was used. Both intervention programs were carried out along 6 sessions. Theoretical contents were analyzed through questionnaires (COSACUES and COSACUES-AEF) and muscular endurance through three physical tests (Biering-Sørensen Test, Side Bridge Test and Prone Forearm Plank Test) before and after the intervention. Motivation levels (Feeling Scale) and perception of effort (OMNI Scale) were measured after each session. The results obtained did not show significant differences between methodologies, but differences have been found in terms of gender and type of methodology. Girls were shown to assimilate better contents with the gamified methodology. There was also a greater perception of effort and greater motivation with the gamified intervention. Therefore, the application of gamified educational interventions by teachers can be an interesting strategy to increase the levels of motivation and effort of students.

How One Feels During Resistance Exercises: A Repetition-by-Repetition Analysis Across Exercises and Loads

Context: The Feeling Scale (FS) is a unique and underexplored scale in sport sciences that measures affective valence. The FS has the potential to be used in athletic environments as a monitoring and prescription tool. Purpose: To examine whether FS ratings, as measured on a repetition-by-repetition basis, can predict proximity to task failure and bar velocity across different exercises and loads. Methods: On the first day, 20 trained participants (10 females) completed 1-repetition-maximum (1-RM) tests in the barbell bench and squat exercises and were introduced to the FS. In the following 3 sessions, participants completed 3 sets to task failure with either (1) 70% 1-RM bench press, (2) 70% 1-RM squat (squat-70%), or (3) 80% 1-RM squat (squat-80%). Sessions were completed in a randomized, counterbalanced order. After every completed repetition, participants verbally reported their FS ratings. Bar velocity was measured via a linear position transducer. Results: FS ratings predicted failure proximity and bar velocity in all 3 conditions (P < .001, R2 .66–.85). Based on the analysis, which included over 2400 repetitions, a reduction of 1 unit in the FS corresponded to approaching task failure by 14%, 11%, and 11%, and to a reduction in bar velocity of 10%, 4%, and 3%, in the bench, squat-70%, and squat-80%, respectively. Conclusion: This is the first study to investigate whether the FS can be used in resistance-training environments among resistance-trained participants on a repetition-by-repetition basis. The results indicate that the FS can be used to monitor and prescribe resistance training and that its benefits should be further explored.

EFEITOS DOS JOGOS REDUZIDOS SOBRE OS MARCADORES PSICOFISIOLÓGICOS DE ATLETAS DE FUTSAL FEMININO

O objetivo do estudo foi analisar o efeito da quantidade de balizas em jogos reduzidos no futsal (JRF’s) sobre a carga interna e resposta afetiva. Participaram do estudo oito atletas adultas de futsal feminino, que treinavam regularmente cinco vezes por semana. Foram analisadas duas sessões de treinamento: 1) JRF1baliza 4 x 4 com uma baliza para cada equipe; 2) JRF3balizas 4 x 4 com três balizas para cada equipe. A ordem dos JRF’s foi escolhida de forma randomizada. Para análise da carga interna utilizou-se a escala CR 0-10 de percepção subjetiva de esforço (PSE) e para a resposta afetiva, utilizou-se a escala de sentimento (feeling scale). Utilizou-se o teste t pareado para análise da resposta psicofisiológica, considerando significativo um valor p < 0,05. Em nossos resultados os valores de PSE foram semelhantes entre os JRF’s (JRF1baliza: 4,5 ± 1,7 vs. JRF3balizas: 4,4 ± 0,7, p > 0,05) da mesma forma para a resposta afetiva (JRF1baliza: 0,2 ± 0,8 vs. JRF3balizas: 0,1 ± 1,0, p > 0,05), adicionalmente observou-se que os valores de PSE fixaram-se em “um pouco difícil” e a resposta afetiva permaneceu positiva durante ambos os JRF’s. Em suma, conclui-se que os JRF1baliza e JRF3balizas obtiveram respostas semelhante nos marcadores psicofisiológicos (PSE e Afeto) em atletas adultas de futsal feminino.
