Can different degrees of resistance training improve mood states in patients with fibromyalgia? A randomized controlled trial.

The purpose of this study was to look at the effects of low and high intensity resistance training (RT) on the mood states of fibromyalgia patients (FM). A total of 69 women participated in the study, with 31 healthy women serving as control group (HC), and 28 women diagnosed with FM being randomly assigned to one of two RT groups: low intensity or high intensity. Ten women diagnosed with FM formed a group of preferred intensity (PI). FM patients were subjected to 8 weeks of supervised RT with low, high, or PI doses. The exercise protocol was the same for both groups, with large muscle group exercises. Each intervention group performed a specific number of repetitions and rest periods based on the intensity. Training sessions took place twice a week. The HC received no type of intervention. The Brunel mood scale was used to assess mood states. When the mood profiles of patients with FM and healthy women were compared, patients with FM showed a worse mood profile. Low and high intensity RT for eight weeks did not improve the mood profile of FM patients. Anger showed a significant difference between LIRT and HIRT groups in the follow-up period (p=0.01); similarly significant differences between HIRT and HC were seen at baseline and at the 4 week evaluation in vigor (p=0.01 and p=0.001) and fatigue (p=0.01 and p=0.03). FM patients have a worse mood profile than healthy women, and eight weeks of low and high intensity RT did not result in significant improvements.

Acute effect of strength training on mood of patients with fibromyalgia syndrome.

Fibromyalgia syndrome (FM) is a musculoskeletal disorder characterized by chronic pain and frequently associated changes in mood states. The aim of this study was to analyze the acute effect of strength training (ST) sessions on the mood states of patients with fibromyalgia. A total of 110 FM patients were eligible for this study. After the inclusion criteria, twenty-eight women with FM (mean age: 51.88±10.22 years) performed three sessions of ST. Each training session worked the main muscle groups and lasted 60 min. Three sets of 12 repetitions were performed with 1-min intervals between them. Outcome measures were assessed at baseline, after one session, and after three ST sessions. The Brunel Mood Scale (BRUMS) was used to assess mood states, and the Wilcoxon test was used to verify differences in mood after one and three ST sessions. The ST practice had positive effects on the patients' mood states after a single session. Reductions in anger, mental confusion, mood depression, fatigue, and tension were observed. The results of the 3rd ST session were similar. We concluded that a single ST session was sufficient to improve the mood states of patients with fibromyalgia.

The influence of high-intensity interval training on anthropometric variables of adults with overweight or obesity: a systematic review and network meta-analysis.

OBJECTIVE: The goal of this study was to evaluate the influence of high-intensity interval training (HIIT) on anthropometric variables in adults afflicted with overweight or obesity and to compare the effects with those of moderate-intensity continuous training. METHODS: A computer literature search was performed for HIIT intervention studies that evaluated anthropometric variables in adults afflicted with overweight or obesity. RESULTS: Of the 857 articles retrieved in the electronic search, 48 met the inclusion criteria. The analyses demonstrated that HIIT was effective in decreasing body mass (-1.45 kg [95% CI: -1.85 to -1.05 kg]), body mass index (-0.44 kg m-2 [95% CI: -0.59 to -0.30 kg m-2 ]), waist circumference (-2.3 cm [95% CI: -3.1 to -1.4 cm]), waist/hip ratio (-0.01 [95% CI: -0.02 to -0.00]), body fat percentage (-1.29% [95% CI: -1.70% to -0.87%]) and abdominal visceral fat area (-6.83 cm2 [95% CI: -11.95 to -1.71 cm2 ]). When considering equalization between the two methods (energy expenditure or workload matched), no differences were found in any measure except body mass (for which HIIT was superior). CONCLUSIONS: High-intensity interval training and moderate-intensity continuous training results were similar, particularly when equalization between the two methods was considered. Thus, HIIT can be used as a secondary method for the treatment of obesity in adults.

Application of Infrared Thermal Imaging in a Violinist with Temporomandibular Disorder.

Temporomandibular disorders (TMD) consist of a group of pathologies that affect the masticatory muscles, temporomandibular joints (TMJ), and/or related structures. String instrumentalists, like many orchestra musicians, can spend hours with head postures that may influence the biomechanical behavior of the TMJ and the muscles of the craniocervicomandibular complex (CCMC). The adoption of abnormal postures acquired during performance by musicians can lead to muscular hyperactivity of the head and cervical muscles, with the possible appearance of TMD. Medical infrared thermography is a non-invasive procedure that can monitor the changes in the superficial tissue related to blood circulation and may serve as a complement to the clinical examination. The objective of this study was to use infrared thermography to evaluate, in one subject, the cutaneous thermal changes adjacent to the CCMC that occur before, during, and after playing a string instrument.

Características de desempenho e de carcaça em diferentes genótipos de codornas de corte / Performance and carcass traits of different meat type genotypes

Objetivou-se com este trabalho comparar e correlacionar as características de desempenho e de carcaça em codornas de corte do nascimento aos 35 dias de idade. Foram utilizadas 1176 codornas de um dia, machos e fêmeas, de sete genótipos de codornas de corte (EV1, EV2, UFV1, UFV2, UFV3, LF1 e LF2), distribuídas em delineamento inteiramente ao acaso, com ensaio fatorial 7x2 (genótipo x sexo), em sete repetições com 12 codornas por unidade experimental. As codornas foram pesadas individualmente do nascimento aos 35 dias de idade, em intervalos semanais. Aos 35 dias de idade, dois machos e duas fêmeas de cada genótipo e repetição foram amostrados e abatidos para avaliação do peso de carcaça e dos cortes nobres. As análises estatísticas foram conduzidas utilizando-se o procedimento GLM e CORR com a opção MANOVA do SAS para avaliar as diferenças entre os genótipos e a correlação entre as variáveis. Não houve interação (P≥0,05) entre genótipo e sexo para as características de desempenho (peso e ganho de peso nas diferentes idades). Entretanto, houve efeito significativo da interação genótipo x sexo (P<0,05) para as características de pesos de carcaça, peito e coxa+sobrecoxa. Em geral, as codornas dos grupos genéticos UFV1, UFV2 e UFV3 foram as mais pesadas dos sete aos 35 dias de idade e apresentaram maiores rendimentos de carcaça. Como observado pelas correlações fenotípicas, a tendência é que codornas que apresentam maior peso corporal e ganho de peso irão apresentar maior peso de carcaça e dos seus principais cortes.(AU)

This study was carried out to compare and relate the performance and carcass traits of different quail genotypes from hatch to 35 days of age. A total of 1176 one-day-old quails of both sexes were allotted in a completely randomized experimental design, in a 7x2 factorial scheme (genotypes x sexes), in seven replicates with 12 quails per experimental unit. Quails of each genotype were weighed weekly from hatch to 35 days of age. At 35 days of age two males and two females of each genotype and replicate were sampled and slaughtered to evaluate carcass weight and main cut yield. Statistical analyses were performed by GLM and CORR procedure from the Statistical Analysis System (SAS, 2000, version 9.0), with the MANOVA option of the SAS device to assess the differences between the genotypes and the correlation between variables. There was no interaction (P≥0.05) between genotype and sex with the performance characteristics of weight and weight gain. However, there was a significant effect of genotype x sex (P<0.05) for the characteristics carcass,breast, thigh and drumstick weights. In general, quails of genetic groups UFV1, UFV2 and UFV3 were heavier from 7 to 35 days of age. We observed that for the correlation the tendency is that quail that showed higher body weight and weight gain will have greater housing and main cuts weight.(AU)

Three-dimensional analysis of the cranio-cervico-mandibular complex during piano performance.

Piano players, as well as other musicians, spend a long time training to achieve the best results, sometimes adopting unnatural body positions that may cause musculoskeletal pain. This paper presents the preliminary results of a study targeting the analysis of the head and cervical postures of 17 piano players during musical performance. It was found, as a common feature, that the players tilt the head to the right and forward towards the score and keyboard. Players who know the score by heart tend to move their heads more compared to the ones who have to keep their eyes on the score.
