Cross-Sectional and Longitudinal Associations between Leisure Time Physical Activity, Mental Well-Being and Subjective Health in Middle Adulthood
2019
Previous studies have shown that participation in leisure time physical activity is related to better mental well-being and subjective health. However, the associations between different types of leisure time physical activities and different dimensions of mental well-being have rarely been studied. In addition, longitudinal research, analyzing possible causal relations between these variables, is lacking. To investigate these research questions, data gathered at ages 42 and 50 (present N = 303) for the Finnish Jyväskylä Longitudinal Study of Personality and Social Development were used. Physical activity was assessed as frequency of participation at ages 42 and 50, and at age 50 also as fr…
Ekspiratorisk flow avgrensingar under fysisk belastning hos ungdommar med astma : Før og etter 10 vekers intervensjon
2019
Masteroppgave folkehelsevitenskap ME516 - Universitetet i Agder 2019 Background:Asthma is a chronic inflammatory disorder associated with variable airflo w obstruction and bronchial hyperresponsivness. Asthma may interfere with the ability of childre n and adolescents to participatein physical activity, as well ascreatebarriers towards involvement. Physical activity is an important stimulus for asthma symptoms. Exercise-induced bronchoconstriction is traditionally used when physical activity is the cause of asthma symptoms, but this is measured after exercise. There is little knowledge about flow limitat io n during exercise. Aim:The purpose of this study is to investigate expiratory flow l…
Influencia de los distintos tipos y parámetros del ejercicio físico sobre la calidad seminal: una revisión sistemática de la literatura
2019
Es de sobra conocida la importancia positiva de la actividad fisica correctamente prescrita en terminos de intensidad y volumen sobre diferentes alteraciones metabolicas, osteomusculares, cognitivas, etc. La infertilidad es una patologia cuya epidemiologia esta al alza por los cambios en los habitos de nuestra vida cotidiana, como la dieta inadecuada o la radiacion de las nuevas generaciones de aparatos electricos. No existen demasiadas evidencias divulgativas sobre sus causas y efectos, asi como tampoco del papel del ejercicio en la reversion de sus sintomas. Con la finalidad de obtener y sintetizar la informacion mas relevante sobre la influencia de los diferentes tipos y parametros del e…
Muscle follistatin gene delivery increases muscle protein synthesis independent of periodical physical inactivity and fasting
2020
Blocking of myostatin and activins effectively counteracts muscle atrophy. However, the potential interaction with physical inactivity and fasting in the regulation of muscle protein synthesis is poorly understood. We used blockade of myostatin and activins by recombinant adeno-associated virus (rAAV)-mediated follistatin (FS288) overexpression in mouse tibialis anterior muscle. To investigate the effects on muscle protein synthesis, muscles were collected 7 days after rAAV-injection in the nighttime or in the daytime representing high and low levels of activity and feeding, respectively, or after overnight fasting, refeeding, or ad libitum feeding. Muscle protein synthesis was increased by…
Adherence to a Mediterranean diet is associated with lower incidence of frailty: A longitudinal cohort study
2018
Background & aims There is a paucity of data investigating the relationship between the Mediterranean diet and frailty, with no data among North American people. We aimed to investigate if adherence to a Mediterranean diet is associated with a lower incidence of frailty in a large cohort of North American people. Methods This study included subjects at higher risk or having knee osteoarthritis. Adherence to the Mediterranean diet was evaluated using a validated Mediterranean diet score (aMED) as proposed by Panagiotakos and classified into five categories. Frailty was defined using the Study of Osteoporotic Fracture (SOF) index as the presence of ≥2 out of: (i) weight loss ≥5% between b…
Associations of physical activity intensities, impact intensities and osteogenic index with proximal femur bone traits among sedentary older adults
2021
Background Dynamic high-intensity physical activity is thought to be beneficial for older adults’ bone health. Traditional volume-based processing of accelerometer-measured physical activity data, quantified on a minute-per-minute basis, may average out sporadic high impact activity, whereas accelerometer data processing approaches based on identifying impacts can capture also these potentially beneficial short activity bursts. We investigated the associations between habitual physical activity and proximal femur bone traits among sedentary older adults utilizing three different numerical treatments of accelerometer-data to examine, if impact-based processing approaches are more suitable to…
Role of anthropometric factors, self-perception, and diet on weight misperception among young adolescents: a cross-sectional study
2018
Adolescence overweight and obesity have increased considerably, and the misperception of their weight status could reduce the efficiency of intervention programs. The aim of this study was to evaluate the prevalence rate of misperception and to assess the relationship between weight perception and anthropometric parameters, self-perception, physical activity, and adherence to the Mediterranean diet. A total of 1643 young adolescents (11–16 years old) were surveyed in a cross-sectional investigation during two scholastic years (period October–May of 2012–2013 and 2013–2014) in 15 secondary schools of Sicily, southern Italy. Data on demographic information, anthropometric characteristics (bio…
Effectiveness of postoperative home-exercise compared with usual care on kinesiophobia and physical activity in spondylolisthesis:A randomized contro…
2017
Objective: To study the effectiveness of a 12-month exercise therapy on kinesiophobia and physical activity in patients with spondylolisthesis after lumbar spine fusion. Design: Randomized controlled trial. Subjects: Patients (n = 98) with spondylolisthesis who had undergone lumbar spine fusion. Methods: All patients (mean age 59 years) had received lumbar spine fusion surgery and identical postoperative instructions. Three months postoperatively, they were randomized into an exercise group (n = 48) or usual care group (n = 50). The exercise group received 12-month progressive home-based training with regular booster sessions, and the usual care group a single session of physiotherapy instr…
Seasonal variation of BMI at admission in German adolescents with anorexia nervosa.
2018
Objective Recent preliminary studies indicated a seasonal association of BMI at admission to inpatient treatment for anorexia nervosa (AN), indicating lower BMI in the cold season for restrictive AN. An impaired thermoregulation was proposed as the causal factor, based on findings in animal models of AN. However, findings regarding seasonality of BMI and physical activity levels in the general population indicate lower BMI and higher physical activity in summer than in winter. Therefore, we aimed to thoroughly replicate the findings regarding seasonality of BMI at admission in patients with AN in this study. Method AN subtype, age- and gender-standardized BMI scores (BMI-SDS) at admission, …
Body appreciation and body appearance pressure in Norwegian university students comparing exercise science students and other students
2021
Abstract Background Body image is considered a core issue for public health and associates with university students’ overall health. Due to positive associations between exercise and body image, it has been suggested that students within an exercise science program might be more body appreciative compared to other students. On the other hand, the strong societal idealization of the athletic body may expose them to a pressure of having a specific body appearance, which may result in unfavorable health consequences. Nevertheless, studies investigating these hypotheses are lacking. We therefore aimed to explore the level and associations of body appreciation, body appearance pressure, body ima…
