BACKGROUND: There is not enough information on the effects of compression therapy in soccer players during recovery after matches. So the objective of this study was to examine the effect of wearing compression garments during soccer matches and during recovery period on physical responses. METHODS: Eighteen semi-professional soccer players participated in this study. A two-stage crossover design was chosen. Participants acted as controls in one match and were assigned to an experimental group (compression stockings group, full-leg compression group, shorts group) in the other match...

BACKGROUND: The inertial flywheel device causes an increase in eccentric overload during training. The aim was to study muscle oxygen saturation produced during an inertial flywheel squat training, comparing it with a barbell squat training. METHODS: Twelve male adults performed a barbell squat training (3 x 8 reps, 75-80% 1RM) and a flywheel squat training (3 x 8 reps, all-out). Muscle oxygen saturation (%SmO2), total hemoglobin (tHb), reoxygenation, heart rate (HR), lactate, vertical jumps, maximal voluntary isometric contraction and rated perceived exertion (RPE) were studied...

Fotini Boufidou, Angelos Halaris
The concept of neuroprogression describes the progressive course of the disorder and stresses the progressive, recurrent, and chronic course of the disease entity under consideration. It subsumes clinical manifestations of the disease process and may also entail morphological, biochemical, neurochemical, immunological, physiological, and genetic aspects that contribute to the progressive course of the disease in question. In an attempt to identify the appropriate agent or method that could arrest neuroprogression in psychiatric patients, we conducted an evaluation of the use of anti-inflammatory drugs under the perspective of current pharmacological and neurophysiological data...

High intensity interval training (HIIT) elicits similar physiological adaptations as moderate intensity continuous training (MICT) despite less time commitment. However, there is debate whether HIIT is more aversive than MICT. This study compared physiological and perceptual responses between MICT and three regimes of HIIT. Nineteen active adults (age = 24.0 ± 3.3 yr) unfamiliar with HIIT initially performed ramp exercise to exhaustion to measure maximal oxygen uptake (VO2 max) and determine workload for subsequent sessions, whose order was randomized...

BACKGROUND: Oxidative stress and muscle damage occur during exhaustive bouts of exercise, and many runners report pain and soreness as major influences on changes or breaks in training regimens, creating a barrier to training persistence. Methylsulfonylmethane (MSM) is a sulfur-based nutritional supplement that is purported to have pain and inflammation-reducing effects. To investigate the effects of MSM in attenuating damage associated with physical exertion, this randomized, double-blind, placebo-controlled study evaluated the effects of MSM supplementation on exercise-induced pain, oxidative stress and muscle damage...

BACKGROUND: Intense exercise has the potential to increase oxidative stress and cause muscle damage. Mitogen-activated protein kinases (MAPKs) and nuclear factor-κB (NF-κB) are two major regulators of gene transcription in response to oxidative stress in the skeletal muscle. Pure capillarisin (CAP) isolated from Artemisia capillaris Thunberg is known to have antioxidant and anti-inflammatory effects. HYPOTHESIS/PURPOSE: We hypothesized CAP to exert antioxidant activity against exercise-induced oxidative stress and suppress acute inflammatory response...

Few publications of exercise-induced rhabomyolysis currently exist in the medical literature besides case reports. However, this condition can be severe, resulting in hospitalization and IV fluid administration to prevent serious sequelae. This report describes a case of exercise-induced rhabdomyolysis caused by a CrossFit workout. A 31-year-old female presented with 2 days of bilateral upper extremity pain and soreness, which began 2 days after she completed a CrossFit workout. Workup revealed an elevated creatine phosphokinase (CPK) of 18 441 U/L, consistent with exercise-induced rhabdomyolysis, and elevated liver function tests and elevated D-dimer, although her renal function was normal...

Obesity is a major risk factor of cardiovascular, osteoarthritis, metabolic and pulmonary disorders, and exercise is an efficient method for treating obesity. However, obese patients often complain of dyspnea on exertion, which makes it difficult to continue exercise program. Obesity is also known to have an adverse effect on pulmonary function. The purpose of this study was to examine the effects of a comprehensive obesity rehabilitation (COR) program on pulmonary function in Japanese patients with morbid obesity...

Exercise may exert beneficial effects on cognitive functions and play an important role in the prevention of neurodegenerative diseases. Such effects seem to be mediated by changes in anti-oxidative status, but limited information is available on the nature of molecular pathways supporting the antioxidant effects of exercise in the brain. In this study 3-5-month-old male Wistar albino rats were subjected to three times/week moderate intensity exercise on a rodent treadmill for a period of 6 weeks. The tissue antioxidant activity towards various reactive oxygen species (ROS) was determined in the hippocampus...

Post-exertional malaise (PEM) is a cardinal symptom of myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS), which often distinguishes patients with this illness from healthy controls or individuals with exclusionary illnesses such as depression. However, occurrence rates for PEM fluctuate from subject to how the symptom is operationalized. One commonly utilized method is exercise testing, maximal or submaximal. Many patients with ME and CFS experience PEM after participating in these tests, and often show abnormal results...

OBJECTIVES: Individual differences in adolescent exercise behavior are strongly influenced by genetic factors. The affective response to exercise is a potential source of these genetic influences. To test its role in the motivation to exercise, we estimated the heritability of the affective responses during and after exercise and the overlap with the genetic factors influencing regular voluntary exercise behavior. DESIGN: 226 twin pairs and 38 siblings completed two submaximal exercise tests on a cycle ergometer and a treadmill and a maximal exercise test on a cycle ergometer...
