Aim: To investigate the energy expenditure of amateur eSport athletes between sitting and an eSport gaming session. Materials & methods: Eleven amateur male eSport athletes (age: 21.73 ± 3.50 years, weight: 76.00 ± 12.51 kg, height: 1.81 ± 0.06 m) were included. After recording the resting values, eSports playing values were recorded using an open circulation oxygen consumption analyzer (QuarkCPET, COSMED, Albano Laziale, Italy). Also, action per min (APM) scores were recorded. Results: When comparing the respiratory frequency, metabolic equivalent of task values and energy expenditure values of the participants, a significant increase was observed in all three values (p < 0.05 for each). Conclusion: eSports players, who are considered to be physically inactive by sitting, spend approximately 40% more energy than sitting, even at the amateur level. According to APM, more energy can be spent in tournaments and at the elite level.

Abstract Background Sedentary time poses a risk to health. Substituting physical activity for inactivity is obvious but this requires a behavior change. Interventions advocated to decrease uninterrupted physical inactivity (defined as Metabolic Equivalent of Task (METS) less than 1.5) are important. One such intervention is accomplished with the Gentle Jogger (GJ), a low risk motorized wellness device which produces effortless, rapid motion of the lower extremities simulating locomotion or fidgeting. GJ produces health benefits in type 2 diabetes, heart disease, and high blood pressure. The purpose of this trial was to ascertain whether GJ increases METS above 1.5 to explain its effectiveness despite sedentary behavior or whether tapping is responsible. Methods A randomized single-arm trial was conducted. Subjects were randomized to begin the study in either the supine or seated postures and on the same day crossed over with the starting posture reversed. Oxygen consumption was measured at rest and during GJ. Results Twenty-six subjects were studied (15 women and 11 men) with a mean age of 44 ± 15 years and BMI 27.9 ± 5.0, 19 were overweight or obese, and 7 had normal BMI. GJ increased oxygen consumption and METS 15% in the seated posture and 13% in the supine posture. No individual receiving GJ achieved METS exceeding 1.5. Conclusions In a moderately obese population, GJ in seated or supine posture did not exceed 1.5 METS. The values are comparable to those reported for sit-stand interventions and cannot explain the health benefits of GJ. Trial registration ClinicalTrials.gov, NCT03602365. Registered on July 26, 2018

AbstractObjective:Even though sub-Saharan African women spend millions of person-hours per day fetching water and pounding grain, to date, few studies have rigorously assessed the energy expenditure costs of such domestic activities. As a result, most analyses that consider head-hauling water or hand pounding of grain with a mortar and pestle (pilão use) employ energy expenditure values derived from limited research. The current paper compares estimated energy expenditure values from heart rate monitors v. indirect calorimetry in order to understand some of the limitations with using such monitors to measure domestic activities.Design:This confirmation study estimates the metabolic equivalent of task (MET) value for head-hauling water and hand-pounding grain using both indirect calorimetry and heart rate monitors under laboratory conditions.Setting:The study was conducted in Nampula, Mozambique.Participants:Forty university students in Nampula city who recurrently engaged in water-fetching activities.Results:Including all participants, the mean MET value for head hauling 20 litres (20·5 kg, including container) of water (2·7 km/h, 0 % slope) was 4·3 (sd 0·9) and 3·7 (sd 1·2) for pilão use. Estimated energy expenditure predictions from a mixed model were found to correlate with observed energy expenditure (r2 0·68, r 0·82). Re-estimating the model with pilão use data excluded improved the fit substantially (r2 0·83, r 0·91).Conclusions:The current study finds that heart rate monitors are suitable instruments for providing accurate quantification of energy expenditure for some domestic activities, such as head-hauling water, but are not appropriate for quantifying expenditures of other activities, such as hand-pounding grain.

Public parks and gardens are gaining numerous outdoor fitness equipment (OFE), easily accessed by the public. Most people use this equipment without any guidance and thus there is a need for basic guidelines on how to use the equipment. This study offers a practical guideline for exercising on one of the most widely used pieces of OFE, the outdoor stepping machine (OSM). Thirty-four healthy adults (nine females, 25 males) participated in workouts of three separate stepping exercises at different intensities, controlled by stepping cadence. At each 5-minute phase, rated perceived exertion (RPE), oxygen consumption (VO2), metabolic equivalent of task (MET) and heart rate (HR) were measured. Corresponding MET values of exercise cadences were calculated to be 5.3 at 80 steps.min−1, 6.0 at 96 steps.min−1 and 6.6 at 112 steps.min−1. Mean values for RPE at each stepping cadence were 9.1 (very light), 11.9 (moderate) and 14.8 (difficult), respectively. In conclusion, when the ACSM’s guidelines for indoor stepper machine (ISM) were taken as a reference, 80 steps.min−1 were suitable for warm-up, 96 and 112 steps.min−1 were appropriate for moderate exercise. People exercising on OSMs could easily use the cadence or the RPE scale as a guideline to exercise at the desired intensity.

Purpose: To investigate different sport-field properties’ influence on muscle-recruitment patterns and metabolic response during a series of running and agility drills. Methods: Eleven male athletes were fitted with a standard multipurpose training shoe. The test protocol consisting of 4 high-intensity trials with 60-s rests between trials performed on 2 fields with different properties. Time-dependent field properties were measured using the American Standards for Testing and Materials protocol (F-1936). A 30-m pretest and posttest sprint determined fatigue and player performance. Electromyography (EMG) recorded muscle activity for vastus medialis, biceps femoris, gastrocnemius medial head, and tibialis anterior, and metabolic activity analyzed maximal oxygen consumption, heart rate, respiratory exchange ratio, metabolic equivalent, and energy expenditure. Results: A difference was calculated for muscle activity across trials (P = .01) for both surfaces. Muscle activity was <13% on the field with less energy return (P = .01). Metabolic components (maximal oxygen consumption, heart rate, respiratory exchange ratio, metabolic equivalent, and energy expenditure) were significantly different across trials (P = .01) but not significantly different between fields. The participants completed the agility course (5.2%) faster on the field with greater energy return, while caloric expenditure was similar between fields. Conclusions: The findings indicate that field mechanical properties influence muscle-activation patterns. The field demonstrating the greatest magnitude of energy return produces the lowest sprint and agility course times; however, performing on a field exhibiting unfamiliar mechanical properties could cause the athlete to produce atypical movement patterns that might contribute to overuse of the neuromuscular system.

Background and objectives: Active commuting to school (ACS) is a promising strategy to increase the daily physical activity (PA) in youths. However, more studies are required to objectively quantify the mode of commuting to school, as well as the health impact of this behavior. Thus, the aims of this study were: (1) to objectively determine the mode of commuting to school using GPS; (2) to quantify the sedentary time, PA levels, energy expenditure, and the steps derived from each mode of commuting; and (3) to analyze the associations between ACS trips and sedentary time, PA, energy expenditure, and steps. Participants and Methods: A total of 180 trips to school were detected, which corresponded to 18 adolescents (12 girls, mean age = 15 ± 0.0 years old). Mode of commuting to school was detected using a novel method merging GPS data in the Personal Activity Location Measurement System (PALMS), whereas sedentary time, PA levels, energy expenditure, and steps were objectively evaluated through accelerometry. Logistic regressions were used to analyze the associations of these variables with walking trips. Results: A total of 115 trips were recorded. Most trips were performed by walk (49.5%), followed by vehicle (39.1%) and mixed transport (11.3%). In the active school trips, youths were less likely to spend minutes in sedentary behaviors (OR: 0.481, p = 0.038), a higher increase on Metabolic-Equivalent of Task (METs) (OR: 5.497, p = 0.013), and greater steps (OR: 1.004, p = 0.029) than in the passive school trips (both active and passive modes were objectively measured). Conclusions: ACS (mainly walking) contribute to higher METs and steps in adolescents. GPS could be an appropriate method to objectively evaluate the PA variables related to the ACS trips.

Objective: To analyze the metabolic responses occurring during the practice of exergames in terms of energy expenditure, oxygen consumption rate, metabolic equivalent and heart rate in adult men and women. Methods: The present study sample was comprised of 102 adults (52 males). Energy expenditure, oxygen consumption rate and metabolic equivalent were assessed with a portable gas analyzer (K4b2). Heart rate was measured with a frequencymeter. All dependent variables were assessed at rest and during the exergame session, which was comprised of four X-box 360 games (volleyball, boxing, athletics, and bowling). Results: Mean age was 34.8 ± 13.4 years. There was a significant increase in resting values during exergame sessions for energy expenditure (male: 467.52%; p < 0.001; female: 393.72%; p < 0.001), oxygen consumption rate (male: 453.97%; p < 0.01; female: 384.74%; p < 0.001), metabolic equivalent (male: 457.40%; p < 0.001; female: 384.74%; p < 0.001) and heart rate (male: 95.10%; p < 0.001; female: 92.26; p < 0.001). When compared to women, men showed significantly higher values for energy expenditure (95% confidence interval = -12.53; -6.67), oxygen consumption rate (95% confidence interval = -4.01; -0.80) and metabolic equivalent (95% confidence interval = -1.18; 0.27) during exergames. Conclusion: A session of exergames is capable of increasing energy expenditure, oxygen consumption rate, metabolic equivalent and heart rate in adults. Men showed higher values in metabolic parameters when compared to women.

Abstract Purpose The Metabolic equivalent of task (MET) score is used in patients’ preoperative functional capacity assessment. It is commonly thought that patients with a higher MET score will have better postoperative outcomes than patients with a lower MET score. However, such a link remains the subject of debate and is yet unvalidated in major urological surgery. This study aimed to explore the association of patients’ MET score with their postoperative outcomes following radical cystectomy. Methods We used records-linkage methodology with unique identifiers (Community Health Index/hospital number) and electronic databases to assess postoperative outcomes of patients who had underwent radical cystectomies between 2015 and 2020. The outcome measure was patients’ length of hospital stay. This was compared with multiple basic characteristics such as age, sex, MET score and comorbid conditions. A MET score of less than four (< 4) is taken as the threshold for a poor functional capacity. We conducted unadjusted and adjusted Cox regression analyses for time to discharge against MET score. Results A total of 126 patients were included in the analysis. Mean age on date of operation was 66.2 (SD 12.2) years and 49 (38.9%) were female. A lower MET score was associated with a statistically significant lower time-dependent risk of hospital discharge (i.e. longer hospital stay) when adjusted for covariates (HR 0.224; 95% CI 0.077–0.652; p = 0.006). Older age (adjusted HR 0.531; 95% CI 0.332–0.848; p = 0.008) and postoperative complications (adjusted HR 0.503; 95% CI 0.323–0.848; p = 0.002) were also found to be associated with longer hospital stay. Other comorbid conditions, BMI, disease staging and 30-day all-cause mortality were statistically insignificant. Conclusion A lower MET score in this cohort of patients was associated with a longer hospital stay length following radical cystectomy with urinary diversion.

Regular physical activity (PA) is known to reduce the risk of serious community-acquired infections. We examined the association of PA with the morbidity and mortality resulting from coronavirus disease (COVID-19) infection in the South Korean population. Patients who tested positive for severe acute respiratory coronavirus 2 and who underwent public health screening between 2014 and 2017 (n = 6288) were included. Age- and sex-matched controls (n = 125,772) were randomly selected from the Korean National Health Insurance Service database. Leisure-time PA was assessed using a self-reported questionnaire. The mean PA levels were lower in the patient than in the control group (558.2 ± 516.3 vs. 580.2 ± 525.7 metabolic equivalent of task (MET)-min/week, p = 0.001). Patients with moderate to vigorous PA (MVPA) were associated with a lower risk of COVID-19 morbidity (odds ratio (OR), 0.90; 95% confidence interval (CI), 0.86–0.95). In addition, a standard deviation (SD) increment in MET/week (525.3 MET-min/week) was associated with a 4% decrease in the risk of COVID-19 morbidity (OR, 0.96; 95% CI, 0.93–0.99). MVPA and an SD increment in MET/week were associated with lower mortality (MVPA: OR, 0.47; 95% CI, 0.26–0.87; per SD increment: OR, 0.65; 95% CI, 0.48–0.88). Higher levels of regular PA were associated with a lower risk of COVID-19 infection and mortality, highlighting the importance of maintaining appropriate levels of PA along with social distancing amid the COVID-19 pandemic.

The purpose of this study was to investigate the energy expenditure and heart rate responses elicited in elite male midget ice hockey players during small-sided games. Nine players (aged 15.89 ± 0.33 years) participated in the study. Maximal progressive treadmill testing in the laboratory measured the relationship of oxygen consumption ([Formula: see text]) to heart rate before on-ice assessments of heart rate during six different small-sided games: 1v1, 2v2, 2v2 with support player, 3v3 with support player, 3v3 with transitions, and 4v4 with two support players. Heart rate was recorded continuously in each game. 3v3 T small-sided game was the most intense for all four intensity markers. All six small-sided games reached 89% HRmax or more with heart rate peaks in active effort repetition. These findings demonstrate that such small-sided games are considered as high intensity games and are an effective training method for ice hockey players.
