Sustituir el tiempo sedentario por la práctica sistemática de actividad física (AF) es uno de los grandes retos  educativos y sociales dirigidos a jóvenes con sobrepeso-obesidad. El objetivo principal fue analizar el efecto en el índice de masa corporal (IMC) de un programa de AF extraescolar que empleó el pulsómetro como mecanismo para cuantificar el volumen e intensidad del ejercicio. Participaron 69 escolares con sobrepeso-obesidad de 9 a 12 años. La muestra se aleatorizó en grupo con programa y pulsómetro (GE1, n=23), grupo con solo programa (GE2, n=23), y grupo control que no realizó programa ni empleó pulsómetro (GC, n=23). Los resultados mostraron que GE1 había disminuido el IMC respecto al GC a los dos y tres meses de intervención (-1.65 kg/m2; p=.037, d de Cohen=.786; y -2.02 kg/m2, p=.006, d de Cohen=.895, respectivamente). GE1 incrementó significativamente el tiempo diario de intensidad máxima de AF medida por el pulsómetro (p=.028). El 86.9% y el 60.8% de los alumnos del GE1 y GE2 respectivamente afirmaron estar bastante o totalmente de acuerdo con el ítem “He comprobado que realizo más actividad física diaria que antes”. La mayoría de niños y padres del GE1 consideraron la experiencia como positiva y motivante para realizar más AF. Se concluye que un programa dirigido desde la Educación Física, que combina AF extraescolar y emplea el pulsómetro como mecanismo de control, disminuye el IMC en jóvenes con sobrepeso-obesidad después de dos meses de aplicación, aumenta la motivación por la práctica físico-deportiva, e implica cambios positivos en los hábitos de salud familiares. Abstract. Replacing sedentary time with systematic practice of PA is one of the major social and health challenges of globalized world. The main aim of this research was to analyze the effect of a program based on extracurricular PA, using heart rate monitor to quantify the volume and intensity of PA, on the body mass index (BMI). 69 young students with overweight-obesity aged nine to 12 years participated in this study. The sample was randomly split in two groups: PA program and heart rate monitor (EG1, n=23), PA program without heart rate monitor (EG2, n=23), and control group, whose members did not carry out any program nor used any heart rate monitor (CG, n=23). Results showed that GE1 decreased BMI more than CG after two and three months of intervention (-1.65 kg/m2; p=.037, Cohen’s d=.786; y -2.02 kg/m2, p=.006, Cohen’s d =.895, respectively). G1 significantly increased the daily time of PA at maximum intensity measured by the heart rate monitor (p=.028). 86.9% and 60.8% of students in EG1 and EG2 respectively, were quite or totally in agreement with the item "I have verified that I carry out more physical activity daily than before". The majority of children and parents in EG1 considered the experience as positive and motivating to practice more PA. A program focused on Physical Education and combining extracurricular PA and heart rate monitor as a control mechanism, decreases BMI in overweight-obese young students after two months of application, increases motivation towards PA and sport practice, and implies positive changes in family health habits.

This study examined the feasibility and potential efficacy of a multi-faceted secondary school–based intervention among low-fit adolescent females. TheSport4Funprogram was designed to promote physical activity participation, fundamental movement skill proficiency, perceived physical competence, and enjoyment of physical activity in secondary school students. The intervention consisted of three components including two practical components—weekly movement skill activities for 90 min during compulsory school sport and sports-based activities for 60 min after school (non-compulsory) for 6 months—and one theoretical component—three 15-min theory sessions completed during homeroom (or roll call) time per week. The control group participated in their regular school activities. Compared with females in the control group, those in the intervention group showed a greater increase in total weekday accelerometer counts per min (adjusted difference, 77.49; 95% CI, 8.21–132.77;p = .03; Cohen’s d = 1.26). The difference in total fundamental movement skill components mastered favored the intervention group but was not statistically significant (adjusted difference, 1.48; 95% CI, −1.21–4.17;p = .26, Cohen’s d = 0.48). Targeting fundamental movement skills may be a potentially novel and motivating way to promote activity among low-fit adolescent girls; however, challenges in recruitment and implementation warrant further investigation before adopting this approach more broadly.

Purpose: The current study was intended to assess the effect of a facilitated behavioral intervention based on the extended theory of planned behavior (TPB) on psychological constructs and physical activity among adolescents over a period of eight weeks. Methods: Students (n = 51, 12 ± 0.3 years of age) in the seventh grade at a junior middle school in China were randomly assigned to two groups: the intervention group (n = 24) and the control group (n = 27). Both groups were pre- and post-tested with the related psychological constructs of the extended TPB, along with behavioral measures of the Physical Activity Scale and ActiGraph accelerometer (model wGT3X-BT). The intervention group took part in 45 min classes once per week for 8 weeks, including five indoor theoretical courses and three outdoor basketball matches. The control group was not required to make any change to their normal school day. Also, 2 × 2 repeated measures analysis of variance (ANOVA) was conducted to compare the differences between the two groups, and then t-test was employed to compare the independent and paired differences. Results: Significant increases in pre–post subjective norms (SN) (p = 0.041, Cohen’s d = 0.62), perceived behavior control (PBC) (p = 0.023, Cohen’s d = 0.72), exercise intention (EI) (p = 0.043, Cohen’s d = 0.61), and self-efficacy (SE) (p = 0.035, Cohen’s d = 1.36) were observed in the intervention group. In addition, participants in the intervention group increased their exercise frequency (p < 0.001, Cohen’s d = 1.25) and intensity (p = 0.028, Cohen’s d = 0.68), especially their time spent on light intensity physical activity (light-PA%; p = 0.031, Cohen’s d = 0.68), and their percentage of sedentary time (SB%) was also reduced (from 68% ± 10% to 58% ± 7%, p < 0.001, Cohen’s d = 1.17). Furthermore, the intervention group showed significantly better performance in PBC (p = 0.032, Cohen’s d = 0.62), EI (p < 0.001, Cohen’s d = 1.32), SE (p < 0.001, Cohen’s d = 1.15), SB% (p < 0.001, Cohen’s d = 1.22), light-PA% (p < 0.001, Cohen’s d = 1.12), and total physical activity (TPA) (p = 0.015, Cohen’s d = 0.72) compared to the control group at the post-test. No significant pre post differences were observed for any psychological or behavioral variables in the control group, except for exercise frequency, but the values were still lower than those in the intervention group after the 8-week intervention (3.70 ± 0.72 versus 3.92 ± 0.83). Conclusion: The combined theory-based intervention was effective at improving psychological constructs and physical activity among seventh-grade adolescents in 8 weeks.

More innovative technologies are used worldwide in patient’s rehabilitation after stroke, as it represents a significant cause of disability. The majority of the studies use a single type of therapy in therapeutic protocols. We aimed to identify if the association of virtual reality (VR) therapy and mirror therapy (MT) exercises have better outcomes in lower extremity rehabilitation in post-stroke patients compared to standard physiotherapy. Fifty-nine inpatients from 76 initially identified were included in the research. One experimental group (n = 31) received VR therapy and MT, while the control group (n = 28) received standard physiotherapy. Each group performed seventy minutes of therapy per day for ten days. Statistical analysis was performed with nonparametric tests. Wilcoxon Signed-Rank test showed that both groups registered significant differences between pre-and post-therapy clinical status for the range of motion and muscle strength (p < 0.001 and Cohen’s d between 0.324 and 0.645). Motor Fugl Meyer Lower Extremity Assessment also suggested significant differences pre-and post-therapy for both groups (p < 0.05 and Cohen’s d 0.254 for the control group and 0.685 for the experimental group). Mann-Whitney results suggested that VR and MT as a therapeutic intervention have better outcomes than standard physiotherapy in range of motion (p < 0.05, Cohen’s d 0.693), muscle strength (p < 0.05, Cohen’s d 0.924), lower extremity functionality (p < 0.05, Cohen’s d 0.984) and postural balance (p < 0.05, Cohen’s d 0.936). Our research suggests that VR therapy associated with MT may successfully substitute classic physiotherapy in lower extremity rehabilitation after stroke.

The purpose of the present study was to investigate which of two strategies, Video Feedback with Pedagogical Activity (VF-PA) or Video Feedback (VF), would be more beneficial for the remote error correction of the snatch weightlifting technique during the confinement period. Thirty-five school aged children with at least three months of weightlifting experience were randomized to one of three training conditions: VF-PA, VF or the Control group (CONT). Subjects underwent test sessions one week before (T0) and one day after (T1) a six-session training period and a retention test session a week later (T2). During each test session, the Kinovea version 0.8.15 software measured the kinematic parameters of the snatch performance. Following distance learning sessions (T1), the VF-PA improved various kinematic parameters (i.e., barbell horizontal displacements, maximum height, looping and symmetry) compared with T0 (p < 0.5; Cohen’s d = 0.58–1.1). Most of these improvements were maintained during the retention test (T2) (p<0.01, Cohen’s d = 1.2–1.3) when compared withT0. However, the VF group improved only twoparameters (i.e., barbell symmetry and horizontal displacement) at T1 (p < 0.05; Cohen’s d = 0.9), which were not maintained at T2. Better horizontal displacement and looping values were registered during the retention test in the VF-PA group compared with theCONT group (p < 0.05, Cohen’s d = 1.49–1.52). The present findings suggest combining video feedback with pedagogical activity during the pandemic induced online coaching or physical education to improve movement learning in school aged children.

Purpose. To determine whether theory-based physical activity (PA) interventions for overweight and obese female cancer survivors lead to increased PA and improved health. Methods. This systematic review examined randomized controlled trials analyzing the impact of theory-based PA interventions on overweight and obese female cancer survivors through December 2016. Searches of 5 electronic databases revealed 10 articles that included 1351 participants who met the inclusion criteria. Results. Participants were primarily non-Hispanic white (74%-100%) breast or endometrial cancer survivors. Intervention characteristics and PA assessment tools varied greatly. Adherence (68%-99%) and retention (79%-100%) were relatively high. Social cognitive theory was utilized as the theoretical construct in 9 of the 10 studies. Home-based interventions led to small improvements in PA (Cohen’s d range = 0.25-0.31), whereas home-based plus center-based interventions led to moderate to large improvements (Cohen’s d range = 0.45-1.02). Only three of the studies assessed psychosocial behavioral processes associated with PA, and the results were mixed. Health-related outcomes included improvements in aerobic fitness (Cohen’s d = 0.32-1.1 in 5 studies), large absolute decreases in waist circumferences (>6 cm in 3 of 5 studies; Cohen’s d = −0.31 to −1.02), and no change in inflammatory biomarkers (in 2 studies). Only one serious adverse event (pelvic stress fracture) was attributed to the interventions. Conclusions. Theory-based PA interventions are safe and feasible for overweight and obese female cancer survivors. Interventions that include a center-based component showed moderate to large effect sizes for PA. Future studies should evaluate behavioral variables and more health-related clinical outcomes.

To investigate the effect of B-ultrasound-guided nerve block on analgesia and sedation in patients with acute cholecystitis undergoing puncture and drainage. Methods 96 patients with acute cholecystitis who underwent puncture and drainage from May 2018 to November 2020 were randomly divided into control group and observation group by random number table method, with 48 cases in each group. The patients in the control group were anesthetized by local infiltration. The patients in the observation group were anesthetized by B-ultrasound-guided nerve block. Heart rate, blood pressure, analgesia score, sedation score, and oxidative stress level were compared between the two groups. Results At the time of puncture (T2), heart rate (HR) and mean arterial pressure (MAP) in the two groups were significantly lower than those before operation (T1) (P<0.05); at the end of operation (T3), HR and MAP in the control group were significantly higher than those at T1 (P<0.05); at T2, HR and MAP in the observation group were significantly higher than those in the control group (P<0.05); at T3, HR and MAP in the observation group were significantly lower than those in the control group (P<0.05). AtT2 and T3, Ramsay sedation score in both groups was significantly lower than that at T1 (P<0.05), while Ramsay score in the observation group was significantly higher than that in control group (P<0.05); atT2 and T3, visual analog scale (VAS) pain score in both groups was significantly higher than that at T1 (P<0.05), while VAS score in the observation group was significantly lower than that in the control group (P<0.05). After operation, the levels of serum malondialdehyde (MDA) and superoxide dismutase (SOD) in the two groups were significantly higher than those before operation (P<0.05), and the levels of serum total antioxidant capacity (T-AOC) were significantly lower than those before operation (P<0.05); after operation, the levels of serum SOD and T-AOC in the observation group were significantly higher than those in the control group (P<0.05), and the levels of MDA in the observation group were significantly lower than those in the control group (P>0.05). Conclusion B-ultrasound-guided nerve block anesthesia can maintain the stable hemodynamic index of patients with acute cholecystitis undergoing puncture and drainage therapy, improve the analgesic and sedative effect and reduce the oxidative stress response of the body.

BACKGROUND Access to physical activity among youth with spina bifida (SB) is much lower than it is for children without disability. Enjoyable home-based exercise programs are greatly needed. OBJECTIVE Our objective is to examine the feasibility of a virtual reality (VR) active video gaming system (ie, bundle of consumer-available equipment) to meet US physical activity guidelines in two youth with SB. METHODS Two youth with SB—a 12-year-old female and a 13-year-old male; both full-time wheelchair users—participated in a brief, 4-week exercise program using a popular VR head-mounted display: Oculus Quest (Facebook Technologies). The system included a Polar H10 (Polar Canada) Bluetooth heart rate monitor, a no-cost mobile phone app (VR Health Exercise Tracker [Virtual Reality Institute of Health and Exercise]), and 13 games. The intervention protocol was conducted entirely in the homes of the participants due to the coronavirus disease 2019 (COVID-19) pandemic. The VR system was shipped to participants and they were instructed to do their best to complete 60 minutes of moderate-intensity VR exercise per day. Exercise duration, intensity, and calories expended were objectively monitored and recorded during exercise using the heart rate monitor and a mobile app. Fatigue and depression were measured via self-report questionnaires at pre- and postintervention. Participants underwent a semistructured interview with research staff at postintervention. RESULTS Across the intervention period, the total average minutes of all exercise performed each week for participants 1 and 2 were 281 (SD 93) and 262 (SD 55) minutes, respectively. The total average minutes of moderate-intensity exercise performed per week for participants 1 and 2 were 184 (SD 103) (184/281, 65.4%) and 215 (SD 90) (215/262, 82.1%) minutes, respectively. One participant had a reduction in their depression score, using the Quality of Life in Neurological Disorders (Neuro-QoL) test, from baseline to postintervention, but no other changes were observed for fatigue and depression scores. Participants reported that the amount of exercise they completed was far higher than what was objectively recorded, due to usability issues with the chest-worn heart rate monitor. Participants noted that they were motivated to exercise due to the enjoyment of the games and VR headset as well as support from a caregiver. CONCLUSIONS This study demonstrated that two youth with SB who used wheelchairs could use a VR system to independently and safely achieve exercise guidelines at home. Study findings identified a promising protocol for promoting exercise in this population and this warrants further examination in future studies with larger samples.

The aim of the study was to analyse the body composition among women after radical mastectomy. The body compositions of 30 women after radical mastectomy (study group) were compared with those of 30 healthy females (control group). The method of electrical bioimpedance was used to analyse body composition. The significant differences between the groups, unfavourable for women, following mastectomy concerned body mass (p = 0.021), BMI (p = 0.049), fat mass (%) (p = 0.007), fat mass (kg) (p = 0.005), total body water (%) (p = 0.002), left upper limb fat mass (p = 0.013) as well as right upper limb fat mass (p = 0.022). The body composition of women after radical mastectomy was significantly worse compared to the control group. The majority of subjects were overweight and had high levels of body fat. Abnormal body composition is a modifiable risk factor of breast cancer; therefore, improving lifestyle is important in the prevention and treatment of this disease. There is a need for education, dietary supervision and physical activity in women following radical mastectomy. The innovation of our study was the use of the modern bioelectrical impedance analysis (BIA) method, which does not cause ionisation and is a gold standard in the field of body composition analysis. In future research, we plan to broaden the assessment of lifestyle and the significance of diet and physical activity in the prevention and treatment of breast cancer.

Law enforcement officers are sometimes required to make split-second use of force decisions. One factor that can impact their decision-making process is the presence of a weapon. This experiment sought to improve the speed and accuracy of weapon identification in a dynamic use of force scenario through the principles of deliberate practice. This research utilized randomized control trial with random assignment to either a control or test condition. Eighty-seven participants completed the pretest, intervention, and posttest. Participants’ vision was recorded via a mobile vision-tracker. With only 20 minutes of training, the test group made 1/3 the amount of decision errors as the control group (Cohen’s d = 0.95). The test group was about 16% faster than the control group at visually finding the object in the suspect’s hand and determining if it was a gun or not (Cohen’s d = 0.91).

Physicians in traditional Chinese medicine have found that acupoints and meridians have effects on specific parts of the body. The aim of this study was to see how acupressure at distal acupuncture points of a specific meridian affects heart rate variability (HRV) and oxygenation of the trapezius muscle. Forty-one female participants were randomly allocated to three groups. Subjects in the Stomach Meridian acupuncture point (ST) group received acupressure at ST 34, ST 36, and ST 41, subjects in the Large Intestinal Meridian acupuncture point (LI) group received acupressure at LI 4, LI 10, and LI 11, and subjects in the control group did not receive any stimuli. HRV and oxygenation of the trapezius muscles were measured. The high frequency components of HRV in the control and LI groups tended to be higher than those in the ST group. Total hemoglobin in the control and LI groups eventually reached significantly higher levels than in the ST group. While oxyhemoglobin (ΔO2Hb) in the control and LI groups did not change, ΔO2Hb in the ST significantly decreased temporarily.
