People with an intellectual disability have high levels of sedentary behaviour (Temple, Frey, & Stanish, 2006) and health conditions associated with inactivity such as cardiovascular disease (Draheim, 2006) and obesity (Rimmer & Yamaki, 2006). Physical activity has been identified as one of the most successful strategies used to decrease these health risks. Four participants with an intellectual disability were recruited from the Special Olympics Athletic Club and participated in a 9-week strength and aerobic exercise program which consisted of a face-to-face program and an at-home component. During the face-to-face program participants took part in an aerobic warm up, strength training using exercise bands, skill development, and games. The strength skills were introduced progressively over the 9-weeks and were analyzed for mastery at the end of each face-to-face session using a procedural task analysis check list. Mastery was reached if participants completed a skill three consecutive times with no prompting. However, once a skill was completed with no more then visual prompting it was added to the at-home component of the program. At the end of each face-to-face session participants planned two additional days per week to exercise in their homes. The at-home component included an interactive exercise DVD that mirrored the strength and aerobics exercises introduced at the face-to-face program. Completion of the planned exercises was confirmed by self-report in log books and conversation with the researcher during prompting telephone calls. Pre and post tests for self-efficacy and a program satisfaction questionnaire were also conducted. Three participants reached mastery for biceps curls and one participant reached mastery for triceps extensions and back leg raises. Three participants completed all six strength exercises and one participant completed four exercise skills with no more than visual prompting. Participants required less prompting as the weeks progressed even with an increase in the number of skill components being tested. Adherence to the at-home component of the program for each participant was: 100%, 94%, 94%, and 28%. A dependent t-test revealed that self-efficacy toward exercise did not significantly increase from pre-test (M = 12.1) to post-test (M = 13.3) t (3) = 2.03, p = .14. These findings suggest that adults with an intellectual disability can acquire exercise band strength skills in a relatively short period of time and some participants are able to utilize these skills consistently at home. Participants in the current study failed to improve their self-efficacy toward exercise; however pre-test self-efficacy scores were quite high.

Anecdotal evidence suggests that caffeine ingestion (mostly in the forms of coffee and tea consumption) is prevalent amongst firefighters and yet there is no data on whether this behaviour should be identified, measured, or monitored. PURPOSE: The purpose of this experiment was to determine the physiological and psychophysical effects of caffeine ingestion during repeated bouts of simulated firefighter work. In a randomized, double blind, crossover design, ten healthy males (age 36 ± 9.8 yr, body mass 88.3 ± 5.7 kg, height 182.78 ± 3.9 cm, approximate caffeine use 492.8 ± 318.2 mg/day) completed three 10 min work bouts (WB) at an intensity one work load below ventilatory threshold wearing full Firefighter personal protective equipment (PPE) and breathing through a self contained breathing apparatus (SCBA) on two different occasions. One hour before exercise each subject ingested either a 6 mg•kg-1 of caffeine (CAFF) or dextrose placebo (PLA), as well as, 500 ml of water. During the work trials, expired gases were sampled for oxygen consumption ( O2), carbon dioxide production ( CO2), respiratory exchange ratio (RER), minute ventilation ( E), respiratory rate (RR), tidal volume (Vt), and total air consumed (AcVE). Core temperature (Tc), heart rate (HR), oxyhemoglobin saturation (% O2 sat), capillarized blood lactate (BLa), rating of perceived exertion (RPE) (10pt Borg), perceived thermal distress (PTD), and sweat loss were also measured. Physiological strain index (PSI) was calculated from HR and Tc values. Tc was significantly higher in all CAFF WB compared to PLA (37.83 ± 0.08 oC vs. 37.61 ±0.12 oC) (p ≤ 0.05). E and Vt were also significantly increased in CAFF whereas, RPE was significantly decreased (p ≤ 0.05). The elevated Tc values caused an increase in calculated PSI in the CAFF condition during exercise (p ≤ 0.01). CAFF increases in E and Vt also increased AcVE. In conclusion, a caffeine induced elevation in Tc caused increased strain as indicated by calculated PSI during repeated work bouts during exercise below ventilatory threshold wearing full PPE and breathing through an SCBA. Elevated Tc in the CAFF condition likely caused increases in E, Vt and AcVE. Thus, caffeine ingestion may have to be monitored in firefighters during work days.

The purpose of this study was to investigate whether recreation is a context for fostering resilience in at risk youth. Five at risk youth were recruited from past relationships with the researcher and with the help of local child-serving agencies. The researcher was also a participant in the inquiry. The youth were selected because they had experienced significant life adversity in their past but were deemed resilient because they had exhibited positive outcomes over a period of time. The research was guided by a Phenomenological paradigm. Two qualitative and one quantitative data collection methods were used. Data collection consisted of the completion of the Protective Factors Scale (PFS) questionnaire, email questionnaire/journaling and personal interview. These were used to capture the full, lived experience of the participants. Results were analyzed using the measurement tool provided with the PFS and NVivo qualitative software. Axial coding was used to identify higher order themes and synthesizing was used to merge stories and experiences. The data revealed five higher order themes that are discussed in detail. Recommendations for future research are presented and implications for practice are discussed.

This study examined the metabolic and thermal responses of 14 firefighters during four repeated work bouts of treadmill exercise in a thermoneutral laboratory, working at an intensity similar to typical firefighting tasks (30-34 ml·kg-1·min-1), while wearing firefighting protective equipment and breathing from a self-contained breathing apparatus. Each work bout consisted of treadmill walking at 93.8 m·min-1 and 8% grade for 8 min followed by 4 min of passive rest. Oxygen consumption remained unchanged between all four work bouts (p>0.05). Ventilation increased significantly (p<0.05) during the first three work bouts from 57.1 (±3.1) to 68.7 (±2.7) L·min-1. Percent heart rate reserve increased significantly (p<0.05) during each work bout, from 76.0 (±1.8) % HRR during the first to 97.2 (±1.1) % HRR during the fourth work bout. Core temperature increased significantly (p<0.05) during each work bout from 36.87 (±0.07) to 38.87 (±0.10) °C from the first to the fourth work bout, as did some of the psychophysiological measures.

Desta forma, o objetivo do estudo foi investigar quais as mudanças pertinentes a serem realizadas pelos professores de Educação Física atuantes no oitavo e/ou nono anos do Ensino Fundamental em relação ao material didático, para o ensino do sistema de classificação do esporte, elaborado pela Secretaria de Educação do Estado do Rio Grande do Sul, de acordo com as necessidades presentes em suas práticas pedagógicas, e se essas alterações atendem a outro grupo de professores que atuam no mesmo nível de ensino. Utilizando o método da pesquisa-ação contou com a participação efetiva de sete professores, divididos em dois grupos: A - desenvolveu as aulas com o material didático original e B - utilizou o material didático modificado pelos integrantes do primeiro grupo. Os resultados foram organizados em três categorias de discussão: compreensão e avaliação do sistema de classificação do esporte, compreensão e avaliação do material didático, implementação do material didático referente ao sistema de classificação do esporte. Na primeira categoria foram observados fatores favoráveis ao ensino do sistema de classificação, destacando-se principalmente uma melhor apresentação, organização e estruturação do conteúdo e a diversidade de modalidades esportivas contempladas. Em relação à segunda categoria, inicialmente os professores demonstraram inseguranças e receios, principalmente pelo fato de não terem experiência no trato com material didático, entretanto, após a sua utilização, ressaltaram que este pode se apresentar como um importante instrumento de... / This study was related to the sport classification system, using internal logic as a reference, based on the criteria of cooperation, interaction with the opponent, comparative performance and tactical objectives of the action, using printed educational material - teacher's notebook and student's notebook. Thus, the aim of the study was to investigate which are the relevant changes that should be made by physical education teachers, working in the eighth and/or ninth grade regarding the educational material, to teach the sport classification system, developed by the Rio Grande do Sul Department of State Education, according to the existing teaching needs, and whether these changes address other groups of teachers who work at the same level of education. Using the action research method, this study had the effective participation of seven teachers, who were divided into two groups: A - developed the lessons with original educational material and B - used the teaching materials modified by the members of the first group. The results were organized into three categories for discussion: understanding and assessment of the sport classification system, understanding and assessment of educational material, implementation of the educational material related to the sport classification system. In the first category, favorable factors related to teaching of the classification system were observed, mainly emphasizing better presentation, organization and structuring of content and the diversity of the sports that were taught. Regarding the second category, initially the teachers showed insecurities and fears, mainly due to not having experience in dealing with the educational material, however, after using the material, they emphasized that it can be an important teaching tool, which helps the pedagogical process, as long as the teacher is allowed to make changes in accordance to their educational realities. As for the third category, a big part of...

Além da terapia medicamentosa, alternativas não farmacológicas, como atividade física e orientação nutricional, podem auxiliar no tratamento da doença. A influência desses fatores em alguns biomarcadores, como as β-secretases, tem sido relacionada a alterações em alguns quadros da doença. Assim, o objetivo do presente estudo foi analisar o nível de atividade física, estado nutricional e níveis plaquetários de BACE 1 e BACE 2 em idosos com doença de Alzheimer nos estágios leve e moderado e em idosos cognitivamente preservados. Ainda, comparar grupos e a correlacionar estas variáveis. Para tanto, participaram do estudo 32 idosos com DA e 32 idosos hígidos. Para verificar o nível de atividade física os idosos utilizaram um acelerômetro e responderam ao questionário Baecke modificado para idosos. A avaliação do estado nutricional consistiu na coleta das medidas antropométricas: peso (kg), estatura (m), circunferências e pregas cutâneas. Também foi aplicada a Mini Avaliação Nutricional. Por meio de coleta sanguínea, foram analisados os níveis plaquetários de BACE 1 e BACE 2 dos grupos. Além disso, foram aplicados testes de rastreamento da função cognitiva, estagiamento da DA e sintomas depressivos dos participantes. Para análise dos dados, foi verificada a normalidade da amostra por meio do teste de Shapiro Wilk. Para dados paramétricos, foi utilizado o teste t de Student e correlação de Pearson, para dados não paramétricos, foi utilizado o teste U de Mann-Whitney e correlação de Spearman. Foi admitido um nível de significância de p<0,05. Os resultados indicam que houve diferença significativa nas médias de nível de atividade física, nas concentrações de BACE 1 e 2 e para a variável Mini Avaliação Nutricional entre os grupos, sendo que o grupo DA apresentou menor nível de atividade física... / Alzheimer's disease (AD) is a neurodegenerative, progressive and causes cognitive impairment in the elderly. Besides drug therapy, nonpharmacological alternatives such as physical activity and nutritional counseling, can help in treating the disease. The influence of these factors in some biomarkers such as β-secretase, has been related to changes in certain tables of the disease. The objective of this study was to analyze the level of physical activity, nutritional status and platelet levels of BACE BACE 1 and 2 in elderly patients with Alzheimer's disease in mild and moderate stages and cognitively preserved elderly. Also compare groups and to correlate these variables. To do so, participated in the study 32 elderly with AD and 32 healthy elderly. To check the level of physical activity the elderly used an accelerometer and the questionnaire Baecke modified for the elderly. The assessment of nutritional status consisted of the collection of anthropometric measurements: weight (kg), height (m), circumference and skinfold thickness. It has also been applied to Mini Nutritional Assessment. Through blood collection, platelet levels of BACE and BACE 1 of 2 groups were analyzed. Furthermore, screening tests were applied cognitive function, depressive symptoms and the staging of the attendees. For data analysis, the normality of the sample using the Shapiro-Wilk test was verified. For parametric data, we used the Student t test and Pearson's correlation to non-parametric data, the Mann-Whitney U test and Spearman correlation. It was admitted a significance level of p <0.05. The results indicate a significant difference in the average level of physical activity at concentrations of BACE 1 and 2 and the variable Mini Nutritional Assessment between the groups, with the DA group had lower levels of physical activity, higher concentrations of BACE and worse nutritional status. In addition, the Spearman test showed negative correlation between the...
