While workplace physical exercise can help manage musculoskeletal disorders, less is known about psychosocial effects of such interventions. This aim of this study was to investigate the effect of workplace physical exercise on psychosocial factors among workers with chronic musculoskeletal pain.The trial design was a 2-armed parallel-group randomized controlled trial with allocation concealment. A total of 66 slaughterhouse workers (51 men and 15 women, mean age 45 years [standard deviation (SD) 10]) with upper limb chronic musculoskeletal pain were randomly allocated to group-based strength training (physical exercise group) or individual ergonomic training and education (reference group) for 10 weeks...

OBJECTIVE: Epilepsy is the most common neurological chronic condition worldwide, affecting about 2% of world population. Temporal lobe epilepsy (TLE) reaches 40% of all cases of this condition, and it is highly refractory to pharmacological treatment. Physical activity has been suggested as complementary therapy for epilepsy. However, there is no consistent information whether all these effects are plenty applicable to females, since clinical and experimental studies concerning physical exercise and epilepsy are largely performed in males...

PURPOSES: Sundown syndrome and sleep disturbances cause people with Alzheimer disease (PAD) and caregivers suffering. Studies have indicated that physical exercise could have a positive impact on sundown syndrome, yet no research has ever explored the relationship between walking and sundown syndrome. The aims of this study were to examine the relationship between sundown syndrome and sleep quality, and determine whether the severity of dementia, sleep quality, and weekly duration of walking influenced sundown syndrome, and to assess differences in sundown syndrome and sleep quality in relation to the accompanying walker and weekly duration of walking among people with Alzheimer disease living in the community...

Sibylle Fallet, Jean-Marc Vesin
Photoplethysmographic (PPG) signals are easily corrupted by motion artifacts when the subjects perform physical exercise. This paper introduces a two-step processing scheme to estimate heart rate (HR) from wrist-type PPG signals strongly corrupted by motion artifacts. Adaptive noise cancellation, using normalized least-mean-square algorithm, is first performed to attenuate motion artifacts and reconstruct multiple PPG waveforms from different combinations of corrupted PPG waveforms and accelerometer data. An adaptive band-pass filter is then used to track the common instantaneous frequency component (i...

Tadpole pupil is a rarely encountered phenomenon caused by episodic, segmental iris dilator muscle spasm of short duration (2-15 minutes), occurring in clusters without a known precipitating factor. It has most commonly been described in women aged 28 to 48 years. A few hypotheses on pathogenesis have been discussed but none has been proved. Here, we present an adolescent girl with bilateral tadpole pupil that appeared during physical exercise. This is the first pediatric case of tadpole pupil, not caused by preceding surgery, to be published...

BACKGROUND: Stroke is the leading cause of death in China. According to the Chinese Stroke Screening and Prevention Project, 8 main risk factors were assessed and individuals with 3 or more risk factors were identified as high-risk population of stroke. To explore the potential impropriety of counting the risk factors but ignoring the different strength of association of each risk factor, we performed this study. METHODS: Relevant databases were searched for case-control and cohort studies focusing on the risk factors of stroke...

BACKGROUND: Physical exercise is generally recommended as part of life style changes post stroke. Monitoring cardiovascular effects may help motivate patients for further exercise, and can be an instrument to assess intervention effects in clinical trials. In 1 of 4 stroke patients, the heart rate variability may challenge currently used cardiovascular monitoring. The Graded Cycling Test with Talk Test is a submaximal exercise test independent of heart rate variability, shown reliable for patients with cardiac disease...

In real-world auditory environments, humans are exposed to overlapping auditory information such as those made by human voices and musical instruments even during routine physical activities such as walking and cycling. The present study investigated how concurrent physical exercise affects performance of incidental and intentional learning of overlapping auditory streams, and whether physical fitness modulates the performances of learning. Participants were grouped with 11 participants with lower and higher fitness each, based on their Vo2max value...

PURPOSE: Polycystic ovary syndrome (PCOS) is a common and heterogeneous endocrine disorder, affecting 8-12% of reproductive-aged women. Insulin resistance and body fat excess are common features in these subjects. Increased physical activity and diet modifications are the first recommended approach in the management of these women, at least in overweight/obese subjects. Evaluation of cardiorespiratory fitness (CRF) is important in assessing exercise performance and in monitoring the effects of physical exercise interventions...

BACKGROUND: We hypothesized that the use of oxygen supplementation during aerobic exercise induces less DNA damage than exercise alone. The aim of this study is to assess the level of DNA damage induced by physical exercise with and without oxygen supplementation in chronic obstructive pulmonary diseases (COPD) patients. METHODS: Peripheral blood was collected before and after aerobic exercise in two conditions: (I) aerobic exercise without oxygen supplementation (AE group) and (II) with oxygen supplementation (AE-O2 group)...

Effects of pre-gestational physical activity on the later development of embryos generated in vitro were evaluated. Kunming mice were divided into two groups, namely exercised and unexercised, with the former undergoing physical training on a motor-driven leveled treadmill over a period of 4weeks (5days/week and 60min/day). After that, following superovulation, collection of oocytes from both groups was performed for in vitro fertilization (IVF) and somatic cell nuclear transfer (SCNT). Notably and specifically, natural mating between the unexercised mice was also done for in vivo fertilization (IVIF)...

It has been demonstrated that several aspects of adipose-related physiology including adipokine release, exhibit daily oscillations. Physical exercise exerts a strong influence on adipokine release and a possible reverse disruption of peripheral circadian clocks. The aim of this study was to establish the effects of time of day and the Wingate test on appetite perception, food intake and plasma levels of adipokines. Twenty-four moderately active non-smoking males (mean ± S.D. age: 27.1 ± 3.1 years; height: 1...

Enhanced cardiovascular strain is one of the factors that explains degraded aerobic capacity in hot environments. The cardiovascular system is regulated by the autonomic nervous system, whose activity can be indirectly evaluated by analyzing heart rate variability (HRV) and systolic arterial pressure (SAP) variability. However, no study has addressed whether HRV or SAP variability can predict aerobic performance during a single bout of exercise. Therefore, this study aimed to investigate whether there is an association between cardiovascular variability and performance in rats subjected to treadmill running at two ambient temperatures...
