PURPOSE: Patients with chronic obstructive pulmonary disease (COPD) have body balance deficits, with consequent fall risk. It is possible that body sway in patients with COPD affects their ability to perform daily activities. The purpose of this study was to determine whether body balance is similar in patients with COPD and healthy persons when performing static and dynamic activities. In addition, we wanted to assess whether impairment of balance is related to the presence of falls in patients with COPD...

In recent years, there has been significant uptake of meditation and related relaxation techniques, as a means of alleviating stress and fostering an attentive mind. Several electroencephalogram (EEG) studies have reported changes in spectral band frequencies during Qigong meditation indicating a relaxed state. Much less is reported on effects of brain activation patterns induced by Qigong techniques involving bodily movement. In this study, we tested whether (1) physical Qigong training alters EEG theta and alpha activation, and (2) mental practice induces the same effect as a physical Qigong training...

INTRODUCTION: Evidence from civilian athletes raises the question of whether reproductive dysfunction may be seen in female soldiers as a result of military training. Such reproductive dysfunction consists of impaired ovulation with or without long-term subfertility. METHODS: A critical review of pertinent evidence following an extensive literature search. RESULTS: The evidence points towards reduced energy availability as the most likely explanation for exercise-induced reproductive dysfunction...

Regular physical activity and healthy dietary patterns are commonly recommended for the prevention and treatment of metabolic syndrome (MetS), which is diagnosed at an alarmingly increasing rate, especially among adolescents. Nevertheless, little is known regarding the relevance of physical exercise on the modulation of the metabolome in healthy people and those with MetS. We have previously shown that treadmill exercise ameliorated different symptoms of MetS. The aim of this study was to investigate the impact of a MetS-inducing diet and different intensities of aerobic training on the overall serum metabolome of adolescent rats...

In acute myocardial infarction (AMI), reactive oxygen species may cause irreversible damage to the heart tissue. Physical training is capable of enhancing antioxidant capacity, acting as a cardioprotective factor. We assessed the preventive effects of physical training on the antioxidant and functional responses of the heart of Wistar Kyoto rats after AMI. Wistar Kyoto rats (n = 12) were allocated to sedentary (SED) or trained (EXE - aerobic training on a treadmill) groups. Echocardiographic exams were performed 48 h before and 48 h after the induction of AMI...

INTRODUCTION: Many non-battle injuries among deployed soldiers are due to occupational-related tasks. Given that non-battle injuries are a significant cause of morbidity and mortality, occupational safety and health are of great concern to the military. Some of the leading causes of non-battle injuries in the military are also common in non-military occupational settings. Nationally, falls and motor-vehicle accidents are leading causes of non-fatal occupational injuries in the civilian workforce...

The effects of prolonged physical training on memory performance and underlying synaptic mechanisms were investigated in old C57BL/6 mice. Training via voluntary running wheels was initiated at 16 months of age and continued for 5 months (1 hour per day and 5 days per week), followed by learning and memory test and spine/synapse analysis. Trained old mice were compared with their age-matched sedentary controls and aged adult controls. This training improved hippocampal-dependent spatial learning and memory function in old mice, and enhanced cognition was accompanied by increased density of spines on CA1 pyramidal cells in the hippocampus...

Physical activity offers a paradoxical hormetic effect and a health benefit to cancer survivors; however, the biochemical mechanisms have not been entirely elucidated. Despite the well-documented evidence implicating oxidative stress in breast cancer, the association between health benefits and redox status has not been investigated in survivors who participate in dragon boating. The present study investigated the plasmatic systemic oxidative status (SOS) in breast cancer survivors involved in two distinct physical training exercises...

Physical activity is nowadays an established therapeutic principle concerning primary and secondary prevention of cardiovascular diseases; therefore, in internal sports medicine various aspects go beyond basic cardiological knowledge and require special medical expertise (sports cardiology). Acute cardiac risk is increased during physical activity; therefore, physical activity should be individually phased under consideration of the whole clinical situation. Physical training results in a functional adaptation of the cardiovascular system...

The aim of this study was to test the suitability of using indirect responses for modeling the effects of physical training on performance. We formulated four different models assuming that increase in performance results of the transformation of a signal secondary to the primary stimulus which is the training dose. The models were designed to be used with experimental data with daily training amounts ascribed to input and performance measured at several dates ascribed to output. The models were tested using data obtained from six subjects who trained on a cycle ergometer over a 15-week period...

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is one of the most common mental disorders observed in childhood and adolescence. Its key symptoms - reduced attention, poor control of impulses as well as increased motor activity - are associated with decreased executive functions performance, finally affecting academic achievement. Although drug treatments usually show some effect, alternative treatments are continually being sought, due to lack of commitment and possible side effects...

Visual feedback in general, and from the body in particular, is known to influence the performance of motor skills in humans. However, it is unclear how the acquisition of motor skills depends on specific visual feedback parameters such as the size of performing effector. Here, 21 healthy subjects physically trained to perform sequences of finger movements with their right hand. Through the use of 3D Virtual Reality devices, visual feedback during training consisted of virtual hands presented on the screen, tracking subject's hand movements in real time...

Objective The Nagasaki Kunchi Festival is one of the most famous festivals in Nagasaki. The bearers the floats that are used in this festival undergo long-term training for the performance. However, there have not been any studies on the effects of this training on the health of the float bearers. Methods Thirty-four men ranging in age from 20 to 49 years (mean age: 35.77.6 years) were included in the study. We examined the following parameters before and after the training: body weight (BW), body mass index (BMI), body fat percentage, muscle volume, systolic blood pressure (SBP), diastolic blood pressure (DBP), pulse rate (PR), pulse pressure (PP), bearing power, arterial pressure volume index (API), and arterial velocity pulse index (AVI)...
