Abstract Pain sensitivity decreases with exercise. The mechanisms that underlie this exercise‐induced hypoalgesia ( EIH ) are unclear. Our purpose was to investigate conditioned pain modulation CPM as a potential mechanism of . Sixteen women completed testing during three sessions: painful exercise, nonpainful and quiet rest. Intensity unpleasantness ratings noxious heat stimuli were assessed at baseline following each session. Results showed decreased significantly both exercise sessions p...
There are many benefits associated with meeting current physical activity recommendations. At present, it is unknown whether a reduced sensitivity to pain included among these benefits.The study's purpose was assess the relationship between and sedentary behaviors in sample of healthy women.Self-reported accelerometer measures behavior were collected compared intensity unpleasantness ratings noxious thermal stimuli 21 women (age = 30.0 ± 5.8 yr). On basis data, participants classified into...
To begin to elucidate the mechanisms underlying benefits of exercise for chronic pain, we assessed influence on brain responses pain in fibromyalgia (FM). Complete data were collected nine female FM patients and pain-free controls (CO) who underwent two functional neuroimaging scans, following (EX) quiet rest (QR). Brain ratings noxious heat stimuli compared within between groups. For ratings, there was a significant (p < 0.05) Condition by Run interaction characterized moderately lower...
Accurate assessments of both physical activity and sedentary behaviors are crucial to understand the health consequences movement patterns track changes over time in response interventions. Purpose The study evaluates validity an integrative, machine learning method for processing monitor data relation a portable metabolic analyzer (Oxycon mobile [OM]) direct observation (DO). Methods Forty-nine adults (age 18–40 yr) each completed 5-min bouts 15 activities ranging from vigorous intensity...
Post exertion malaise is one of the most debilitating aspects Myalgic Encephalomyelitis/Chronic Fatigue Syndrome, yet neurobiological consequences are largely unexplored. The objective study was to determine neural acute exercise using functional brain imaging. Fifteen female Syndrome patients and 15 healthy controls completed 30 min submaximal (70% peak heart rate) on a cycle ergometer. Symptom assessments (e.g. fatigue, pain, mood) imaging data were collected week prior 24 h following...
Excessive sedentary time is related to poor mental health. However, much of the current literature uses cross-sectional data and/or self-reported time, and does not assess factors such as bout length. To address these limitations, influence objectively measured including length (i.e. <30 min, ≥30 min) on mood, stress, sleep, was assessed in 271 healthy adults (49% women; age 27.8 ± 3.7) across a 1-year period between 2011 2013 Columbia, SC. Participants completed Profile Mood States...
Pain modulation is a critical function of the nociceptive system that includes ability to engage descending pain control systems maintain functional balance between facilitation and inhibition incoming sensory stimuli. Dysfunctional associated with increased risk for chronic characteristic fibromyalgia (FM). Catastrophizing also common in FM. However, its influence on poorly understood.To determine role catastrophizing central nervous processing during FM via examining brain responses...
Background. Sedentary behavior is a growing public health concern and may have particular relevance for the Parkinson disease (PD) population. However, influence of sedentary time on factors associated with quality life (QOL) in PD unknown. The primary purpose this study was to examine relationships between behaviors markers PD-specific QOL. A secondary physical activity Methods. We assessed active using objective interview measures examined these measure QOL individuals PD. Results. Results...
Background: While widely used and endorsed, there is limited evidence supporting the benefits of activity trackers for increasing physical activity; these devices may be more effective when combined with additional strategies that promote sustained behavior change like motivational interviewing (MI) habit development. Objective: This study aims to determine utility wearable alone or in combination promoting improvements active sedentary behaviors. Methods: A sample 91 adults (48/91 female,...
Cardiorespiratory fitness (CRF) has been shown to be related brain health in older adults. In individuals at risk for developing Alzheimer's disease (AD), CRF may a modifiable factor that could attenuate anticipated declines volume and episodic memory. The objective of this study was determine the association between both hippocampal memory cohort cognitively healthy adults with familial and/or genetic (AD).Eighty-six enrollees from Wisconsin Registry Prevention participated study....
The purpose of this study was to determine whether physical activity and sedentary behaviors interact influence feelings energy fatigue in women.Feelings were assessed 73 women (mean ± SD age = 37 10) who dichotomized based on status (meets recommendations [n 40] vs insufficiently active 33]) the amount uninterrupted time they accumulated (high 38] low 35]). Three 2 × ANOVA conducted relationships between (vigor vitality) fatigue.Results demonstrated a significant main effect for meeting...
Exercise shows promise for improving physical and cognitive functioning, quality of life, mood in individuals with Parkinson's disease (PD). Structured interviews have suggested potential factors influencing participation exercise this population, but no studies examined if they predict behaviour.Thirty persons PD completed the International Physical Activity Questionnaire a semi-structured interview. Time spent exercising was calculated by summing responses recreation, sport, leisure-time...
Exercise acutely improves mood in major depressive disorder (MDD). However, it is unknown whether benefits differ depending on exercise intensity self-selected or prescribed. Purpose This study aimed to compare psychological and biological responses preferred prescribed steady-state intensities a patient-selected intensity. Method Female adults (N = 24, age 38.6 ± 14.0 yr) diagnosed with MDD completed four 30-min sessions of cycling at three (RPE 11, 13, 15) one session (preferred). Order...
Abstract Chronic musculoskeletal pain (CMP) affects ∼25% of the 700,000 Veterans deployed during Persian Gulf War (1990-1991). The cause their is unknown, and there are no efficacious treatments. A small body literature suggests that brain abnormalities exist in (GVs), yet relationships between disease symptoms remain largely unexplored. Our purpose was to compare white matter (WM) integrity GVCMP matched, healthy Veteran controls (GVCO) investigate cerebral WM symptoms. Thirty 31 completed...
Physical activity (PA) is associated with brain health in older adults. However, it unknown whether the current physical recommendations (PAR) impart substantive benefit. The objective of this study was to compare temporal lobe volumes between adults who met PAR and those did not.Ninety-one enrollees from Wisconsin Registry for Alzheimer's Prevention wore an accelerometer seven consecutive days quantify their PA behaviors underwent a T-1 anatomic magnetic resonance imaging scan. Participants...
Physical activity (PA), especially vigorous-intensity PA, has been shown to be related pain sensitivity. The relationship among PA levels and types on endogenous inhibition after exercise, termed exercise-induced hypoalgesia (EIH), remains unclear.This studied examined the EIH response pressure stimuli college-age women of differing levels.Fifty were tested. Pressure threshold (PPT) values assessed before immediately isometric handgrip exercise exhaustion in right left forearms....
Chronic widespread musculoskeletal pain (CMP) is a primary condition of Veterans who were deployed to the Persian Gulf War. The mechanisms that underlie CMP in these are unknown and few efficacious treatment options exist. This study tested effects 16 weeks resistance exercise training (RET) on gray matter (GM) volume white (WM) microstructure War (GWVs) with compared GWV waitlist controls (WLC). Fifty-four GWVs randomly assigned RET (n = 28) or WLC 26). Training involved 10 exercises...
