The cumulative evidence supports that exercise training is associated with a significant small reduction in fatigue among persons with MS.
The cumulative evidence from high quality studies indicates that acute bouts of exercise can yield a small reduction in state anxiety. The research is still plagued by floor effects associated with recruiting persons with normal or lower levels of state anxiety, and this should be overcome in subsequent trials.
and Barbey, AK. Effectiveness of a 16-week high-intensity cardioresistance training program in adults. J Strength Cond Res 31(9): 2528-2541, 2017-The purpose of this study was to determine the efficacy of a novel, 16-week high-intensity cardioresistance training (HICRT) program on measures of aerobic fitness, agility, aerobic power, muscular endurance, lower-body explosive power, and self-reported activity level. The intervention group (N = 129; 63 f, 24.65 6 5.55 years) had a baseline V _ O 2 max of 39.83 6 9.13. These individuals participated in 26, 70-minute exercise sessions, and 4 fitness testing sessions. Participants were matched with a nonexercise control group, paired by sex, age, and baseline V _ O 2 max. Matched controls (N = 129, 63 f, 24.26 6 5.59 years) had a baseline V _ O 2 max of 39.86 6 8.59 and completed preintervention and postintervention V _ O 2 max testing only. The results demonstrate that participants in the fitness intervention group significantly increased their V _ O 2 max (2.72 6 0.31, M diff 6 SE; p , 0.001) and reported being more physically active (0.42 6 0.11, M diff 6 SE; p , 0.001) after the intervention. The matched control group showed no significant pre-post intervention changes. Participants in the fitness intervention showed a significant improvement in 3 of 5 components of the fitness field tests. Specifically, significant improvements were observed for the 1-minute rower (5.32 6 0.505, M diff 6 SE; p , 0.001), 1-minute push-up (8.168 6 0.709, M diff 6 SE; p , 0.001), and 1.5-mile run tests (1.79 6 0.169, M diff 6 SE; p , 0.001). No significant improvements were observed for the shuttle run (p = 0.173) or standing long jump (p = 0.137). These findings demonstrate the efficacy of a novel, HICRT intervention across multiple dimensions of fitness for young-and middle-aged adults. High-intensity cardioresistance training affords flexibility for tailoring to meet desired health and fitness outcomes and makes perceivably daunting high-intensity functional training and multimodal sports training more accessible to general, traditionally nonathletic, populations.
Background One of the reported goals of hip preservation surgery is to prevent or delay the onset of osteoarthritis. This includes arthroscopic surgery to manage Femoroacetabular Impingement (FAI) Syndrome. The purpose of this study was to describe the prevalence of clinically-diagnosed hip OA within 2 years after hip arthroscopy for FAI syndrome, and 2) determine which variables predict a clinical diagnosis of OA after arthroscopy. Methods Observational analysis of patients undergoing hip arthroscopy between 2004 and 2013, utilizing the Military Health System Data Repository. Individuals with prior cases of osteoarthritis were excluded. Presence of osteoarthritis was based on diagnostic codes rendered by a medical provider in patient medical records. Adjusted odds ratios (95% CI) for an osteoarthritis diagnosis were reported for relevant clinical and demographic variables. Results Of 1870 participants in this young cohort (mean age 32.2 years), 21.9% ( N = 409) had a postoperative clinical diagnosis of hip osteoarthritis within 2 years. The 3 significant predictors in the final model were older age (OR = 1.04; 95%CI = 1.02, 1.05), male sex (OR = 1.31; 95%CI = 1.04, 1.65), and having undergone an additional hip surgery (OR = 2.33; 95% CI = 1.72, 3.16). Military status and post-surgical complications were not risk factors. Conclusion A clinical diagnosis of hip osteoarthritis was found in approximately 22% of young patients undergoing hip arthroscopy in as little as 2 years. These rates may differ when using alternate criteria to define OA, such as radiographs, and likely underestimate the prevalence. A more comprehensive approach, considering various criteria to detect OA will likely be necessary to accurately identify the true rates. Females were at lower risk, while increasing age and multiple surgeries increased the risk for an OA diagnosis. OA onset still occurs after “hip preservation” surgery in a substantial number of individuals within 2 years. This should be considered when estimating rates of disease prevention after surgery. Prospective trials with sound methodology are needed to determine accurate rates and robust predictors of osteoarthritis onset after hip preservation surgery.
ObjectivesWe aimed to identify the rate of seven comorbidities (mental health disorders, chronic pain, substance abuse disorders, cardiovascular disorders, metabolic syndrome, systemic arthropathy and sleep disorders) that occurred within 2 years after hip arthroscopy.MethodsData from individuals (ages 18–50 years) undergoing arthroscopic hip surgery between 2004 and 2013 were collected from the Military Health System (MHS) Data Repository (MDR). The MDR captures all healthcare encounters in all settings and locations for individuals within the MHS. Person-level data over 36 months were pulled and aggregated. Seven comorbidities related to poor outcomes from musculoskeletal disorders (mental health disorders, chronic pain, substance abuse disorders, cardiovascular disorders, metabolic syndrome, systemic arthropathy and sleep disorders) were examined 12 months prior and 24 months after surgery. Changes in frequencies were calculated as were differences in proportions between presurgery and postsurgery.Results1870 subjects were identified (mean age 32.24 years; 55.5% men) and analysed. There were statistically significant increases (p<0.001) proportionally for all comorbidities after surgery. Relative to baseline, cases of mental health disorders rose 84%, chronic pain diagnoses increased 166%, substance abuse disorders rose 57%, cardiovascular disorders rose by 71%, metabolic syndrome cases rose 85.9%, systemic arthropathy rose 132% and sleep disorders rose 111%.ConclusionsMajor (potentially ‘hidden’) clinical comorbidities increased substantially after elective arthroscopic hip surgery when compared with preoperative status. These comorbidities appear to have been overlooked in major studies evaluating the benefits and risks of arthroscopic hip surgery.Level of evidencePrognostic, level III.
Introduction With the rapid rise in arthroscopy rates for the management of Femoroacetabular Impingement (FAI) Syndrome, it is important to understand current surgical rates and the impact of these surgeries within the Military Health System (MHS). The purpose of this study was to provide an epidemiological descriptive summary of hip arthroscopy for FAI Syndrome in the MHS and describe perioperative healthcare utilization variables. Methods Eligible beneficiaries ages 18–50, undergoing hip arthroscopy with 2-year follow-up after surgery were included. Healthcare utilization data were abstracted from the MHS Data Repository (MDR) from June 2003 to July 2015, and included all visits, costs, procedures, and prescriptions taking place in both military and civilian hospitals worldwide. Results 1870 patients were included (mean age 32.2 years; 55.5% male). 51.7% of the procedures took place in military versus 48.3% in civilian hospitals. Mean hip-related healthcare costs in the 2-year following surgery were $15,434 per patient. Patients had a median of 3 opioid prescriptions and 72% had a comorbidity present after surgery. Generally, rates of surgery grew annually from 66 cases in 2004 to 422 cases in 2013. Overall complication rates were comparable to other published reports. Procedures in both military and civilian hospitals had the same rates of femoroplasty and labral repairs, however acetabuloplasty procedures occurred at a higher rate in military (18.9%) vs civilian (14.7%) hospitals. Only 58.8% of patients had physical therapy in the year prior to surgery, while 82.7% had it after surgery. Additionally, 50% of patients had received opioid prescriptions in the 1 year prior to surgery, while 38.9% had 3 or greater opioid prescriptions beyond the initial perioperative fill within the 2-year follow-up. Conclusion Rates of arthroscopy have grown in the MHS over the last decade. Complication rates are similar to those reported in other populations and settings. Utilization of physical therapy was much more likely after surgery than prior to it. Opioid use was high prior to surgery and many individuals continued to receive opioid prescriptions beyond the initial perioperative period.
This study examined the following: effects of simulated firefighting (FF) activities under heat stress on sustained attention; whether incident rehabilitation (IR) influences performance; and relationships between performance, affect and personality. Firefighters performed ~18 min of FF. Attention, physiological, perceptual and psychological assessments were made before and after FF, IR and recovery. IR had no effects. Self-rated Energy increased, Tiredness decreased and Anxiety increased immediately post-FF; all returned to baseline 120 min post. The immediate effect of FF was faster reaction time (RT) followed by slowing after recovery. Perceived Energy at baseline was associated (p-values < 0.05) with faster and Tiredness with slower post-FF RTs; Accuracy was unaffected. Conscientiousness was negatively associated with RT before and 120 min following FF. RTs were faster following FF, accuracy was unchanged. Higher baseline Energy/lower Tiredness were associated with faster, less variable RTs at baseline and post-FF. Those with higher Conscientiousness had faster RTs. Research should further investigate higher-level cognitive processing following, or ideally during, FF.
