The gripping coronavirus disease (COVID-19) has imposed dramatic changes to many areas of daily living in all sectors society across the world. We examined relationship between perceived stress and health behaviors among college students during COVID-19 pandemic. An online survey with measures psychological stress, physical activity exercise, sleep social connectedness was distributed June July 2020. completed by 550 (mean age: 21.3 ± 3.8 years, 74.2% female, 94.4% Caucasian).

To compare core muscle activity during resistance exercises performed on stable ground vs. the BOSU Balance Trainer.Twelve trained men back squat, dead lift, overhead press, and curl lifts. The of rectus abdominis, external oblique transversus abdominis/internal erector spinae muscles was assessed. Subjects each lift under three separate conditions including standing with 50% a 1-RM, Trainer 75% 1-RM.Significant differences were noted between 1-RM for abdominis press (P < .05). Conversely,...

The purpose of the study was to compare core muscle activation tradition prone plank with a modified version performed long-lever and posterior-tilt using surface electromyography. To further determine if specific component this more effective than other in enhancing activity, long lever posterior pelvic tilt were studied individually. Nineteen participants all four variations for 30 seconds randomized order 5-minute rest between exercise bouts. Compared traditional plank, displayed...

The aim of this study was to examine the decision-making performance experienced and inexperienced soccer players at four exercise intensities (rest, 40%, 60%, 80% maximal aerobic power). expected demonstrate an inverted-U shape with increasing levels exercise. For players, decision making predicted show no change in increased intensity. Thirty-two adult (16 experienced, 16 inexperienced) were asked answer seven questions as quickly accurately possible for each Results indicated that does...

OBJECTIVE: The purpose of this study was to compare activation the upper body musculature during barbell bench press at varying training intensities. METHODS: Twelve young, resistance-trained men performed sets momentary muscular failure with two different loads: a high -load (HIGH) set 80% 1RM and low-load (LOW) 50% 1RM. Exercise order counterbalanced so that half subjects LOW condition first other HIGH first. Surface electromyography (EMG) used assess mean, peak, iEMG muscle anterior...

The COVID-19 pandemic prompted chaotic changes in the daily lives of K-12 teachers, resulting increased stress and other mental health problems. Limited evidence regarding relationship between physical activity, sleep, perceived among teachers during exists. Therefore, purpose this study was to investigate association sleep quality, psychological pandemic. An online survey measuring distributed across 47 US states September October 2020. Data provided by 635 (mean age: 42 ± 18 years, 74.6%...

Anti-fat bias by professors in physical education departments may interfere with the training provided to pre-service teachers. The purpose of this study was evaluate attitudes toward obese individuals. Professors from randomly selected institutions across all four US regions participated ( N = 94). Participants took Implicit Association Test and answered Anti-Fat Attitude Scale two questions specifically designed measure their teachers majors who are obese. participants exhibited implicit...

The purpose of this study was to compare the activation rectus abdominis (RA), external oblique (EO), lower abdominal stabilizers (LASs), and lumbar erector spinae (LES) during performance 3 traditional trunk exercises vs. exercise on Ab Circle device. Surface electromyography used assess 12 subjects (6 men, 6 women) for conditions, including: crunch, side bridge, quadruped, levels 1-3. For RA, crunch elicited significantly greater activity level 1, bridge 1 2. EO, quadruped. No significant...

SUMMARY OBJECTIVE: The aim was to evaluate the changes in prevalence of physical inactivity Brazilian adults from 2009-2017. METHODS: This study used a time-series research design based on cross-sectional data 462,498 Participants were classified as physically inactive if they indicated not participating activity last three months. Prais-Winsten regression analyzed trends over time. RESULTS: overall stable (p>0.05). Physical increased for women four state capitals (annual growth rate:...

When performing consecutive sets of a resistance exercise, maintaining performance within specified repetition range has been shown to be essential for achieving muscular adaptations conducive different training goals. However, can difficult when using shorter rest intervals between (i.e., < or = 1 min), which may require load reductions. Therefore, the purpose current study was compare keeping constant reducing by percentages during lower-body workout. Ten maximum (10RM) loads were...

Willardson, JM, Simão, R, and Fontana, FE. The effect of load reductions on repetition performance for commonly performed multijoint resistance exercises. J Strength Cond Res 26(11): 2939–2945, 2012—The purpose this study was to compare 4 different loading schemes the free weight bench press, wide grip front lat pull-down, back squat determine extent progressive necessary maintain performance. Thirty-two recreationally trained women (age = 29.34 ± 4.58 years, body mass 59.61 4.72 kg, height...

The aim of the study was to determine association between weight-teasing and physical activity in students from public schools Curitiba, Paraná (Southern Brazil).The sample consisted 95 (48 boys 47 girls) aged 12 14 years old. Perception Weight Teasing (POTS) during Physical Activity Scale assessed frequency experienced by participants. Accelerometers measured activity. BMI weight status Pearson correlations analyzed teasing variables at a significance level 0.05.The relationship not...

We introduce a tool for quantitative evaluation of handwriting features largely adopted during forensic examination questioned documents. The is based on model generation and execution according to which composed elementary movements, called strokes, whose order timing has been learned stored in the brain. Thus, what characterizes individuality, therefore should be inferred from samples available, way sequence strokes are executed. does not aim at reaching conclusion writer's identity when...

This longitudinal study aimed to verify possible changes in the time spent sedentary activities occurring as screen-time, educational, cultural, social, and transportation domains a sample of Brazilian adolescents between 2015 2017.It is prospective with 586 from 12 15 years old at Baseline (2015) enrolled 14 public schools Curitiba, Brazil. The Adolescent Sedentary Activity Questionnaire assessed five (recreational transportation). A series linear random effects regressions analyzed 2017, p...

The purpose of this project was to compare the gaze behavior older adults young during locomotor tasks requiring participants change direction and vary speed walking.Older were further divided into high- low-risk falling groups based on scores in Berg balance scale pre-established risk factor criteria. Gaze measured using applied sciences eye tracking system as walked under four different conditions. results suggest that, independent group or target, fixations target shorter, faster walked....
