Physical activity and planetary health: A scoping review.

Objectives: The behaviors and attitudes associated with event attendance and engagement in physical and sporting activities exert a significant impact on planetary health. This scoping review aims to scrutinize existing literature, elucidate concepts, investigate methodologies, and identify knowledge gaps pertaining to physical activity behavior within the context of planetary health.

Design & Methods: A systematic search across PsycINFO (Psychological Information), Web of Science, and Scopus, guided by Preferred Reporting Items for Systematic Reviews and Meta-Analysis Guidelines for Scoping Reviews (PRISMA-ScR) guidelines, yielded 62 relevant studies.

Methods for Heart Rate Variability Biofeedback (HRVB): A Systematic Review and Guidelines.

Heart Rate Variability Biofeedback (HRVB) has been widely used to improve cardiovascular health and well-being. HRVB is based on breathing at an individual's resonance frequency, which stimulates respiratory sinus arrhythmia (RSA) and the baroreflex. There is, however, no methodological consensus on how to apply HRVB, while details about the protocol used are often not well reported.

Resonance frequency is not always stable over time and could be related to the inter-beat interval.

Heart Rate Variability Biofeedback (HRVB) is based on breathing at an optimal rate (or resonance frequency, RF) corresponding to the respiratory sinus arrhythmia (RSA). Our aim is to check whether the RF is a stable factor and analyse the HRV parameters individually per each breathing rate, comparing it with free slow breathing. A sample of 21 participants were trained in a test-retest HRVB protocol.

Can HRV Biofeedback Improve Short-Term Effort Recovery? Implications for Intermittent Load Sports.

As intensity and physical demands continue to rise in sport competition, faster and better recovery becomes essential. The aim of this study was to assess the effects of HRV biofeedback (HRVB) while recovering from a submaximal aerobic exercise. Ten physically-active graduate students participated in the study, which was conducted in four sessions: exercise with free-breathing recovery, first resonance frequency (RF) detection, second RF detection, and exercise applying HRVB during recovery.

The cafeteria diet: A standardized protocol and its effects on behavior.

Obesity is a major health risk, with junk food consumption playing a central role in weight gain, because of its high palatability and high-energy nutrients. The Cafeteria (CAF) diet model for animal experiments consists of the same tasty but unhealthy food products that people eat (e.g.

mHealth technology for ecological momentary assessment in physical activity research: a systematic review.

Objective: To systematically review the publications on ecological momentary assessment (EMA) relating to physical activity (PA) behavior in order to classify the methodologies, and to identify the main mHealth technology-based tools and procedures that have been applied during the first 10 years since the emergence of smartphones. As a result of this review, we want to ask if there is enough evidence to propose the use of the term "mEMA" (mobile-based EMA).

Design: A systematic review according to PRISMA Statement (PROSPERO registration: CRD42018088136).

Controllability affects endocrine response of adolescent male rats to stress as well as impulsivity and behavioral flexibility during adulthood.

Exposure to stress during adolescence exerts a long-term impact on behavior and might contribute to the development of several neuropsychiatric disorders. In adults, control over stress has been found to protect from the negative consequences of stress, but the influence of controllability at early ages has not been extensively studied. Here, we evaluated in a rodent model the effects of repeated exposure in adolescent male rats to controllable versus uncontrollable foot-shock stress (CST or UST, respectively).

Treadmill Intervention Attenuates the Cafeteria Diet-Induced Impairment of Stress-Coping Strategies in Young Adult Female Rats.

The current prevalence of diet-induced overweight and obesity in adolescents and adults is continuously growing. Although the detrimental biochemical and metabolic consequences of obesity are widely studied, its impact on stress-coping behavior and its interaction with specific exercise doses (in terms of intensity, duration and frequency) need further investigation. To this aim, we fed adolescent rats either an obesogenic diet (cafeteria diet, CAF) or standard chow (ST).

Long-term moderate treadmill exercise promotes stress-coping strategies in male and female rats.

Recent evidence has revealed the impact of exercise in alleviating anxiety and mood disorders; however, the exercise protocol that exerts such benefit is far from known. The current study was aimed to assess the effects of long-term moderate exercise on behavioural coping strategies (active vs. passive) and Hypothalamic-Pituitary-Adrenal response in rats.

Epidemiology of Dog and Cat Abandonment in Spain (2008-2013).

Millions of pets are abandoned worldwide every year, which is an important animal welfare and financial problem. This paper was divided into three studies. Our first two studies were designed as a national survey of animal shelters to profile the population of stray dogs and cats, as well as to gather information on both relinquishment and adoption.

Long-term wheel running changes on sensorimotor activity and skeletal muscle in male and female mice of accelerated senescence.

The senescence-accelerated mouse prone 8 (SAMP8) is considered a useful non-transgenic model for studying aspects of aging. Using SAM resistant 1 (SAMR1) as controls, the long-term effects of wheel running on skeletal muscle adaptations and behavioral traits were evaluated in senescent (P8) and resistant (R1) male and female mice. Long-term wheel running (WR) led to increases in locomotor activity, benefits in sensorimotor function, and changes in body weight in a gender-dependent manner.

Voluntary exercise promotes beneficial anti-aging mechanisms in SAMP8 female brain.

Regular physical exercise mediates health and longevity promotion involving Sirtuin 1 (SIRT1)-regulated pathways. The anti-aging activity of SIRT1 is achieved, at least in part, by means of fine-tuning the adenosine monophosphate (AMP)-activated protein kinase (AMPK) pathway by preventing the transition of an originally pro-survival program into a pro-aging mechanism. Additionally, SIRT1 promotes mitochondrial function and reduces the production of reactive oxygen species (ROS) through regulating peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), the master controller of mitochondrial biogenesis.

Epigenetic alterations in hippocampus of SAMP8 senescent mice and modulation by voluntary physical exercise.

The senescence-accelerated SAMP8 mouse model displays features of cognitive decline and Alzheimer's disease. With the purpose of identifying potential epigenetic markers involved in aging and neurodegeneration, here we analyzed the expression of 84 mature miRNAs, the expression of histone-acetylation regulatory genes and the global histone acetylation in the hippocampus of 8-month-old SAMP8 mice, using SAMR1 mice as control. We also examined the modulation of these parameters by 8 weeks of voluntary exercise.

Effects of a post-weaning cafeteria diet in young rats: metabolic syndrome, reduced activity and low anxiety-like behaviour.

Among adolescents, overweight, obesity and metabolic syndrome are rapidly increasing in recent years as a consequence of unhealthy palatable diets. Animal models of diet-induced obesity have been developed, but little is known about the behavioural patterns produced by the consumption of such diets. The aim of the present study was to determine the behavioural and biochemical effects of a cafeteria diet fed to juvenile male and female rats, as well as to evaluate the possible recovery from these effects by administering standard feeding during the last week of the study.

Long-term exercise modulates hippocampal gene expression in senescent female mice.

The senescence-accelerated SAMP8 mouse is considered a useful non-transgenic model for studying aspects of progressive cognitive decline and Alzheimer's disease (AD). Using SAMR1 mice as controls, here we explored the effects of 6 months of voluntary wheel running in 10-month-old female SAMP8 mice. Exercise in SAMP8 mice improved phenotypic features associated with premature aging (i.

Physiological and behavioural consequences of long-term moderate treadmill exercise.

The benefits of long-term moderate exercise for health are widely accepted in humans, but few animal studies have been undertaken to characterize the effects of such activity on emotionality and responsiveness to stress. The present study describes the effects of long-term moderate forced treadmill training (36 weeks) on exploratory activity, anxiety-like behaviour, and the resting or stress levels of some physiological variables, including pituitary-adrenal (PA) hormones. Five-week-old male Sprague-Dawley rats were trained on the treadmill (TM) for 36 weeks, using a more moderate training (12m/min, 30min/day, 4-5 days/week) than that currently used in the literature.

Neurophysiological and epigenetic effects of physical exercise on the aging process.

Aging is a gradual process during which molecular and cellular processes deteriorate progressively, often leading to such pathological conditions as vascular and metabolic disorders and cognitive decline. Although the mechanisms of aging are not yet fully understood, inflammation, oxidative damage, mitochondrial dysfunction, functional alterations in specific neuronal circuits and a restricted degree of apoptosis are involved. Physical exercise improves the efficiency of the capillary system and increases the oxygen supply to the brain, thus enhancing metabolic activity and oxygen intake in neurons, and increases neurotrophin levels and resistance to stress.
