A 3-min all-out exercise test (3MT) for running has been developed to determine critical speed (CS) and finite capacity for running speeds >CS (D') which allow for the prediction of time limits (TLIMs) associated with running different distances. Most team sports require shuttle running; however, the 3MT was validated for uninterrupted, track running and not shuttle running. The purpose of this study was to examine the efficacy of shuttle running 3MT to determine critical speed (CS) and D'. A total of 12 subjects were tested using a baseline 3MT along with three separate distance time-trials of all-out shuttle running to determine true CS and D'...

BACKGROUND: Despite clear assessment criteria, studies of molar incisor hypomineralisation (MIH) and hypomineralised second primary molars (HSPM) are marked by inconsistency in outcome measurements. This has detracted from meaningful comparisons between studies and limited interpretation. AIM: To provide a comprehensive manual as a companion to assist researchers in planning epidemiological studies of MIH and HSPM, with particular reference to outcome measurement...

The ability of the circadian clock to adapt to environmental changes is critical for maintaining homeostasis, preventing disease, and limiting the detrimental effects of aging. To date, little is known about age-related changes in the entrainment of peripheral clocks to external cues. We therefore evaluated the ability of the peripheral clocks of the kidney, liver, and submandibular gland to be entrained by external stimuli including light, food, stress, and exercise in young versus aged mice using in vivo bioluminescence monitoring...

BACKGROUND: Though voluntary wheel running (VWR) has been used extensively to induce changes in both behavior and biology, little attention has been given to the way in which different variables influence VWR. This lack of understanding has led to an inability to utilize this behavior to its full potential, possibly blunting its effects on the endpoints of interest. NEW METHOD: We tested how running experience, sex, gonadal hormones, and wheel apparatus influence VWR in a range of wheel access "doses"...

Mitochondrial respiratory complexes become assembled into supercomplexes (SC) under physiological conditions. One of the functional roles of these entities is the limitation of reactive oxygen species (ROS) produced by complex I (CI) of the respiratory chain. We sought to determine whether the systemic antioxidant effect of exercise is mediated by the assembly of mitochondrial CIs into SCs in rats. Male Wistar rats were exercise trained or remained sedentary for ten weeks; then, blood samples were collected, and the gastrocnemius muscle was isolated...

Rehabilitation in patients with advanced cardiac and pulmonary disease has been shown to increase survival and improve quality of life among many other benefits. Exercise training is the fundamental ingredient in these rehabilitation programs. However, determining the amount of exercise is not straightforward or uniform. Most rehabilitation and training program fix the time of exercise and set the exercise intensity to the goals of the rehabilitation program and the exercise-related hurdles of the individual...

PURPOSE OF REVIEW: A common concern regarding pelvic floor surgery is the relatively high risk of recurrence. In an effort to minimize this risk, many surgeons instruct their patients to avoid certain activities during the healing process so as not to damage the repair before proper healing has occurred. However, many of these restrictions have been historically based on little to no hard evidence. The purpose of this review is to present the latest evidence-based recommendations regarding restrictions and limitations after pelvic floor surgery...

REVIEW
Katherine B Frayman, Traci M Kazmerski, Susan M Sawyer
This systematic review synthesizes published articles investigating the prevalence, severity and impact of urinary incontinence (UI), a condition associated with cystic fibrosis (CF). References were identified through searching Medline, Embase and PubMed using the medical subject headings 'cystic fibrosis' AND 'urinary incontinence'. Articles were included if UI prevalence was investigated as an outcome. Twelve studies met selection criteria. The prevalence of UI ranged from 5% to 76%. Age and gender contributed to this variability...

Fish and shellfish are regularly consumed and sold in Ghana, yet studies on arsenic pollution in Ghana are limited largely to ground water. This study evaluated arsenic concentrations in seven species of shellfish and 10 species of fish inhabiting the mouth of Ankobra, Densu and Volta basins in Ghana and assessed the public health implications. Arsenic levels varied from 0.2 to 2.2 mg L(-1) in the three rivers and were higher than WHO recommended values of 10 μg L(-1) for drinking water. Except for Periophthalmus sp...

BACKGROUND: Indoor Cycling (IC) has been gaining recognition and popularity within recent years and few studies have investigated its benefits for sedentary participants. OBJECTIVE: The aim of this study was to evaluate differences in the surface electromyography (sEMG) variables, heart rate (HR), and subjective effort in sedentary participants while they performed an IC session and to compare their results with the trained subjects, to answer the question: Are trained cyclists less susceptible to muscle fatigue, since it is expected that they make less effort? DESIGN: Twenty-six volunteers were split into two groups according to their fitness status and weekly training load...

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...

Given persistently high 30-day readmission rates among patients hospitalized for heart failure, there is an ongoing need to identify new interventions to reduce readmissions. Although exercise programs can improve outcomes among ambulatory heart failure patients, it is not clear whether this benefit extends to reducing readmissions following heart failure hospitalization. We therefore conducted a systematic review of the literature to identify randomized controlled trials examining the impact of exercise programs on hospital readmissions among patients recently hospitalized for heart failure...

The rising prevalence of osteoarthritis and an increase in total hip replacements calls for attention to potential therapeutic activities. Cycling is considered as a low impact exercise for the hip joint and hence recommended. However, there are limited data about hip joint loading to support this claim. The aim of this study was to measure synchronously the in vivo hip joint loads and pedal forces during cycling. The in vivo hip joint loads were measured in 5 patients with instrumented hip implants. Data were collected at several combinations of power and cadence, at two saddle heights...
