Cardiorespiratory fitness (CRF) is routinely investigated in older adults; however, the most appropriate CRF measure to use for this population has received inadequate attention. This study aimed to 1) evaluate the reliability and validity of the oxygen uptake efficiency slope (OUES) as a sub-maximal measurement of CRF; 2) examine demographic, risk-factor, and exercise testing differences in older adults who satisfied standardized criteria for a peak oxygen consumption (V̇O2peak) test compared to those who did not; and 3) determine the difference between directly measured V̇O2peak values and OUES-predicted V̇O2peak values...

The purpose of this study was to determine, using structural equation modelling (SEM), the direct and indirect influence of daily behaviours (i.e. exercise/learning durations), weight status, and physical fitness on academic performance among seventh-grade schoolchildren, after controlling for socioeconomic status. We analysed cross-sectional data from 274 schoolchildren (159 males and 115 females; 12-13 years old). Academic performance was assessed using the total grade points in eight academic subjects. Physical fitness was evaluated using the total score of eight physical fitness tests and weight status using body mass index...

BACKGROUND: Prehabilitation reflects a proactive process of preoperative optimization undertaken between cancer diagnosis and definitive surgical treatment, with the intent of improving physiological capacity to withstand the major insult of surgery. Prehabilitation before GI cancer surgery is currently not widely adopted, and most research has focused on unimodal interventions such as exercise therapy, nutritional supplementation, and hematinic optimization. A review of the existing literature was undertaken to investigate the impact of multimodal prehabilitation programs as a "bundle of care...

BACKGROUND: Postexercise heart rate (HR) recovery presents an exponential decay, with two distinct phases: a fast phase, characterized by abrupt decay of HR, and determined by parasympathetic reactivation; and a slow phase, characterized by gradual decay of HR, and predominantly determined by sympathetic withdrawal. Although several methods have been proposed to assess postexercise HR recovery, none of those methods selectively assesses the time of transition from the fast to the slow phase of the HR recovery curve (HRRPT ), and the magnitude of decay prior to (HRRFP ) and after this point (HRRSP )...

Exercise-induced cardiac remodeling (EICR) and the attendant myocardial adaptations characteristic of the athlete's heart may regress during periods of exercise reduction or abstinence. The time course and mechanisms underlying this reverse remodeling, specifically the impact of concomitant plasma volume (PV) contraction on cardiac chamber size, remain incompletely understood. We therefore studied recreational runners (n=21, aged 34 ± 7 years; 48% male) who completed an 18-week training program (~7 h.w-1) culminating in the 2016 Boston Marathon after which total exercise exposure was confined to <2 h...

Two studies were conducted to assess the reliability and validity of a submaximal warm-up test (SWT) in professional soccer players. For the reliability study, 12 male players performed SWT over three trials, with one week between trials. For the validity study, 14 players of the same team performed SWT and 30-15 Intermittent Fitness Test (30-15IFT) 7 days apart. Week-to-week reliability in selected heart rate (HR) responses [exercise HR (HRex), HR recovery (HRR) expressed as the number of beats recovered within 1 min (HRR60s) and expressed as the mean HR during 1 min (HRpost1)], were determined using intraclass correlation coefficient (ICC) and typical error of measurement expressed as coefficient of variation (CV)...

BACKGROUND AND PURPOSE: There is growing evidence that exercise interventions can mitigate functional decline and reduce fall risk in older adults with Alzheimer disease and related dementias (ADRD). Although physical performance outcome measures have been successfully used in older adults without cognitive impairment, additional research is needed regarding their use with individuals who have ADRD, and who may have difficulty following instructions regarding performance of these measures...

BACKGROUND AND PURPOSE: The 2-minute step test (TMST) is one of many alternatives for measuring exercise capacity. First introduced in 1999 as part of the Senior Fitness Test, the TMST has the advantage of requiring limited space, only a few minutes' time, and no expensive equipment. These advantages notwithstanding, the test must be clinimetrically sound if it is to be recommended. We sought therefore to summarize the literature addressing TMST performance and measurement properties...

The purpose of this research was to describe and interpret the positive body image experiences of women actively engaged in pole fitness. A total of seven women between the ages of 20 and 36 years participated in semistructured one-on-one interviews and follow-up interviews. Participant observation was also used to generate data. Data were analyzed using an interpretative phenomenological analysis approach, and the positive body image experiences of women are represented by five themes: (a) observation and exposure fostering body acceptance, (b) performance promoting self-confidence, (c) personal growth and sexual expression, (d) unconditional community support creates comfort, and (e) body appreciation through physical skill development...

Current evidence suggests that exercise training is beneficial in pulmonary arterial hypertension (PAH). Unfortunately, the standard supervised, hospital-based programs limit patient accessibility to this important intervention. Our proof-of-concept study aimed to provide insight into the usefulness of a prescribed walking regimen along with arginine supplementation to improve outcomes for patients with PAH. Twelve PAH patients (all women) in New York Heart Association (NYHA) functional class (FC) II (n = 7) or III (n = 5) and in stable condition for ≥ 3 months were enrolled...

People seek a greater quality of life and healthy aging that culminates in improved self-esteem and vitality in the performance of daily activities; this is generating a growing number of people enrolled in gyms in search of quick results. However, this training can result in physical and metabolic damage. During physical exercise, under conditions of oxidative stress, changes take place that lead to the onset of fatigue. The Agaricus brasiliensis mushroom is native to Brazil and has therapeutic potential, with widely studied antioxidant and immunomodulatory capabilities...

INTRODUCTION/PURPOSE: Cardiopulmonary exercise testing (CPET) plays an important role in clinical medicine and research. Repeatability of CPET parameters has not been well characterized, but is important to assess variability and determine if there have been meaningful changes in a given CPET parameter. METHODS: We recruited 45 healthy subjects and performed two symptom-limited CPETs within 30 days using a cycle ergometer. Differences in relevant CPET parameters between CPET-1 and CPET-2 were assessed using a paired t-test...

OBJECTIVE: A rapidly accumulating body of research suggests that exercise can improve symptoms and well-being in patients suffering from psychosis. Exercise may also promote neurogenesis in the hippocampus, a structure that plays an important role in the pathophysiology of psychosis. To date, there has not been an intervention focused on exercise prior to the onset of psychosis, a critical time for prevention of more serious illness. METHODS: In this pilot study, 12 young adults at ultrahigh risk (UHR) for psychosis were enrolled in a 12-week open-label exercise intervention...

Soccer players perform approximately 1350 activities (every 4-6 s), such as accelerations/decelerations, and changes of direction (COD) during matches. It is well established that COD and plyometric training have a positive impact on fitness parameters in football players. This study analyzed the effect of a complex COD and plyometric protocol (CODJ-G) compared to an isolated COD protocol (COD-G) training on elite football players.A randomized pre-post parallel group trial was used in this study. Twenty-one youth players were enrolled in this study (mean ± SDs; age 17 ± 0...

OBJECTIVE: We aimed to compare the cardiopulmonary fitness of children with congenital heart diseases (CHD) with that of age-adjusted and gender-adjusted controls. We also intended to identify clinical characteristics associated with maximum oxygen uptake (VO2max) in this population. METHODS AND RESULTS: We included in a cross-sectional multicentre study a total of 798 children (496 CHD and 302 controls) who underwent a complete cardiopulmonary exercise test (CPET)...

BACKGROUND: Exercises that could prevent gait impairment of older adults should be implemented in such a way that practitioners can keep motivation and adherence independent of older adults fitness levels. OBJECTIVE: This study describes how younger and older adults use a non-pedal tricycle to transport their bodies along a pathway. METHODS: Nine younger (24±4.9y) and nine older (66±4.0y) adults participated in this study. They moved along a straight pathway at a self-selected comfortable speed with reflective markers on their main lower limb landmarks...

Background: Certain essential and conditionally essential nutrients (CENs) perform functions involved in aerobic exercise performance. However, increased intake of such nutrient combinations has not actually been shown to improve such performance. Methods: For 1 mo, aerobically fit, young adult women took either a combination of 3 mineral glycinate complexes (daily dose: 36 mg iron, 15 mg zinc, and 2 mg copper) + 2 CENs (daily dose: 2 g carnitine and 400 mg phosphatidylserine), or the same combination with generic mineral complexes, or placebo (n = 14/group)...

Adaptations to long-term exercise training in type 1 diabetes are sparsely studied. We examined the effects of a 1-year individualized training intervention on cardiorespiratory fitness, exercise-induced active muscle deoxygenation, and glycemic control in adults with and without type 1 diabetes. Eight men with type 1 diabetes (T1D) and eight healthy men (CON) matched for age, anthropometry, and peak pulmonary O2 uptake (V̇O2peak), completed a 1-year individualized training intervention in an unsupervised real-world setting...

BACKGROUND: A plateau in volume of oxygen consumption (VO2) is the primary indicator for determining if an individual has reached their maximal aerobic capacity. However, secondary criteria can also be used to identify maximal effort (i.e. lactate level, rating of perceived exertion (RPE), percent of age-predicted maximal heart rate (HR) and respiratory exchange ratio (RER)). Age and gender-specific secondary criteria have been developed for the general population, but no secondary criteria have been established for pregnant women...

RATIONALE: Regulatory focus (i.e., focus on motivation to achieve gains or avoid losses and non-gains) is used to tailor health behavior change interventions, improving efficacy, but is currently assessed by scales that are not health-specific and may capture a version of the construct that is not ideally matched to the rationale for tailoring. OBJECTIVE: We developed and validated a Health Regulatory Focus Scale (HRFS), which assesses tendencies to avoid negative health consequences (prevention focus) or achieve positive health outcomes (promotion focus)...
