Efeitos do polimento na potência aeróbia máxima em atletas de indoor soccer

DOI: http://dx.doi.org/10.5007/1980-0037.2016v18n3p341 The aim of this study was to analyze the effect of tapering on maximum aerobic power (VO2max) in young male indoor soccer athletes. Participants were 78 athletes aged 12-17 years randomly divided into experimental (EG) and control group (CG). Both groups did the same training planning until the last three weeks (tapering phase). Only EG performed tapering. Tapering lasted three weeks adopting the linear tapering method. VO2max was estimated by Yo-Yo intermittent Recovery Level 1 early in the season and in the last week of each. Univariate analysis of covariance (ANCOVA) was conducted for repeated measures to compare VO2max among groups according to mesocycle. The results presented effect of time (F (4.74)= 42.02, p = 0.01) and group (F (2.76) = 35.87, p = 0.01). Overall, the findings of this study suggest that the implementation of the tapering strategy in the last weeks of training is more efficient to improve VO2max than the constant maintenance of loads.

Background and Aims: Generalized anxiety and depression are prevalent in patients with type 2 diabetes. Type 2 diabetes is one of the most common chronic diseases leading to many complications. This study aimed to compare the effectiveness of metacognitive therapy and behavioral activation on depression in the elderly with type 2 diabetes. Materials and Methods: This quasi-experimental study was conducted based on a pretest-posttest design using a follow-up and control group. The study population consisted of elderly with type 2 diabetes who referred to five endocrine and metabolism clinics in region 11 of Tehran, Iran, during 2017. A total of 45 males and females were selected by purposive sampling method based on the inclusion criteria. Then they were assigned randomly to one control and two case groups. The Beck Depression Inventory (Second Edition) was utilized to measure the depression scale. In total, eight 90-min group intervention sessions were held weekly. The data were analyzed in SPSS software (version 25) through analysis of covariance and repeated measures ANOVA. Results: The results showed that metacognitive therapy (F=15.07, P<0.001) and behavioral activation (F=7.09, P<0.008) were significantly effective on depression in the elderly with type 2 diabetes, and there was a significant difference between the experimental and control groups in this regard (P<0.001). Conclusions: This study was conducted to compare the effectiveness of metacognitive therapy and behavioral activation on depression in the elderly with type 2 diabetes. The results showed that metacognitive therapy and behavioral activation were significantly effective on depression in this population with type 2 diabetes. Moreover, behavioral activation was more effective than metacognitive therapy on depression reduction.

And Control

Self-management is a key component of diabetes care and enhancing patient self-efficacy is an important factor. Typical diabetes education programs include strategies to increase self-efficacy, but little information exists about the effectiveness of such programs within Asian and Pacific populations. The Hawai'i Demonstration to Maintain Independence and Employment was a federally funded, community-based randomised trial in which treatment group participants received individualised life coaching and pharmacist counselling over a 12-month period. The study measured changes in diabetes self-efficacy among treatment and control group participants using repeated measures analysis of covariance. Focus group findings provided a comprehensive picture of participants' perception of their experiences in the trial and more specifically the individualised intervention. There was a significant effect of the intervention on diabetes self-efficacy at the p < .01 level [F(1, 187) = 10.40, p = .002]. These findings demonstrate the efficacy of individually tailored approaches to diabetes self-management within a diverse, employed sample.

The Impact

Spending time outdoors fosters a sense of connectedness and empathy with nature and has a clear effect on attitudes and behaviour towards the environment. The purpose of this study was to examine the impact of an outdoor activities intervention program on adolescents’ sense of responsibility towards the environment. Participants included 262 adolescents (135 girls and 127 boys) aged 13-17 years who were divided into experimental (n = 141) and control groups (n = 121). The 15-day outdoor intervention program included trekking, mountain biking, orienteering, archery, ropes courses, canoeing on a lake, via ferrata rock climbing, night hiking, and overnight camping. Participants completed an Environmental Responsibility questionnaire (Zafeiroudi & Hatzigeorgiadis, 2013) before and after participation in the activities program. The questionnaire included five scales that focused on perceptions of information on environmental issues, environmental cognitive and affective beliefs, predisposition for environmental action, and environmentally responsible behaviour. Analysis of variance with repeated measures revealed improved scores amongst adolescents who participated in the intervention program, notably within the specific scales used to evaluate perceived information, affective beliefs, predisposition for individual action, and predisposition for encouraging others. A follow-up analysis of covariance revealed that participants in the experimental group scored higher overall than did those in the control group. Taken together, these findings add to the current literature focused on psychosocial and behavioural mechanisms associated with environmental awareness. Our findings also suggest that outdoor recreational activities may be an effective supplement and a more challenging alternative to programs currently provided by environmental and active leisure associations.

Abstract Objectives The purpose of this exploratory non-randomized controlled study was to determine the acceptance and effectiveness of an 8-week mindfulness-based intervention (MBI) co-designed by a police officer. Methods A pretest-posttest control group design was followed. Participants (MBI group = 20; control group = 18) answered baseline and post-training self-reported measures. In addition, the weekly emotional state of the MBI group was collected. Paired-samples t-test and analysis of covariance were performed for pre-post within-group and between-group differences, respectively, as well as linear mixed effects analysis of repeated measures for week-by-week data. Results High acceptance and attendance rates, as well as significant pre-post within-group differences in the MBI group in mindfulness (η2 = 0.43), self-compassion (η2 = 0.43), depression (η2 = 0.54), anxiety (η2 = 0.46), stress (η2 = 0.51), difficulties in emotion regulation, sleep quality (η2 = 0.57), and burnout (η2 = 0.31–0.47), were identified. Moreover, police officers who underwent the MBI experienced a week by week decrease of anger, disgust, anxiety, sadness, and desire. Finally, after adjusting for pre-test scores, significant between-group differences were found in the way of attending to internal and external experiences (observing mindfulness facet; ηp2 = 0.21), depression symptoms (ηp2 = 0.23), general distress (ηp2 = 0.24), and the degree of physical and psychological exhaustion (personal burnout; ηp2 = 0.20). Conclusions The preliminary effectiveness of this MBI on psychopathology and quality of life outcomes in Spanish police officers was discussed. Previous evidence regarding the promising use of MBIs in this population was supported.

INTRODUCTION: The enhancement of nurses’ risk perception plays a significant role in their preparedness during disasters and emergencies. Therefore, this study aimed to investigate the effect of educational workshops on disaster risk perception in nurses METHODS: This randomized controlled field trial study included 62 nurses working at Razi Hospital, Birjand, Iran. The participants were divided into intervention and control groups. The intervention group was then requested to participate in a one-day intensive educational workshop based on the current national standards. The workshop content included a combination of lecturing methods, round-table exercises, and film display. The data were collected using the demographic characteristic form and researcher-made questionnaires measuring the nurses’ risk perception during disasters and emergencies. Subsequently, the data were analyzed using independent t-test, repeated measures analysis, and Bonferroni post hoc tests. FINDINGS: The mean total score of risk perception were significantly higher in the intervention group before, immediately, and two months after the workshop session, compared to those in the control group (P˂0.001). CONCLUSION: The implementation of nurses’ national preparation program during disasters and emergencies can result in an increase in the nurses’ risk perception during these events. Therefore, regarding the importance of nurses’ preparedness in confrontation with disasters and emergencies, it seems necessary to integrate the National Preparedness Program into the educational programs immediately after recruitment and in the form of in-service courses.
