Hashim Islam, Logan K Townsend, Tom J Hazell
PURPOSE: Few studies have directly compared excess postexercise oxygen consumption (EPOC) and fat utilization following different exercise intensities, and the effect of continuous exercise exceeding 75% of maximal oxygen uptake (VO2 max) on these parameters remains unexplored. The current study examined EPOC and fat utilization following acute moderate- and vigorous-intensity continuous training (MICT and VICT) and sprint interval training (SIT). METHODS: Eight active young men performed 4 experimental sessions: (a) MICT (30 min of running at 65% VO2 max); (b) VICT (30 min of running at 85% VO2 max); (c) SIT (4 30-s "all-out" sprints with 4 min of rest); and (d) no exercise (REST)...

PURPOSE: To create a high-stress shooting among the crowd (SAC) program and to examine its effectiveness in reducing SWAT trainees' stress level and their shooting performance in a simulated hostage-rescue situation. METHOD: After the SAC program was created, it was evaluated using a pretest and posttest experimental design: 98 young male SWAT trainees were randomly divided into experiment and control groups, with the former group trained in hostage rescue, shooting with real persons (high stress), and the latter group trained with "dummy" men (low stress); training for both lasted three days...

Mathieu Gourlan, Julie Boiché, Monica Takito, Bruno Fregeac, Florence Cousson-Gélie
PURPOSE: The theory of planned behavior (TPB) has been criticized for not including interactions between the variables assumed to predict behavior. This study sought to test how TPB variables interact to predict physical activity (PA) in children. METHOD: Four hundred thirty-eight children (Mage  = 8.6 years, SD = 1.6 years) completed a TPB questionnaire and a PA questionnaire at Time 1. The PA measure was repeated 2 months later. Path analyses were performed to test the hypothesized model including interaction terms between TPB variables...

Rosalie Coolkens, Phillip Ward, Jan Seghers, Peter Iserbyt
PURPOSE: To investigate the effect of generalization of engagement in parkour from physical education (PE) to organized and supervised recess on voluntary participation and moderate-to-vigorous physical activity (MVPA). METHOD: Children received a 6-day parkour unit in PE and every two lessons they could voluntarily participate in 20-min parkour recess. Fourteen elementary school classes constituting 281 children (8-10 years old) and 16 PE teachers were randomized to either three supervised or three organized parkour recess sessions...

Adherence to prescribed training intensity (i.e., swim speed) has been conveyed as a key parameter regarding improvements in seasonal performance. Evidence has also suggested swimmers have difficulty complying with coach-prescribed training. How this compliance is affected by a coaching presence and oversight has yet to be examined. PURPOSE: The purpose of this study was to determine swimmers' compliance to prescribed training intensity during 3 observational conditions using activity monitors...

PURPOSE: Research has demonstrated that verbal instructions directing attention externally (i.e., toward the effect of the movement) significantly enhance motor skill performance, and this effect is enhanced when the distance of the external focus relative to the body is increased. However, few studies have investigated this distance-of-focus effect in children. The present study aimed to examine the effect of increasing the distance of an external focus on children's motor performance in 2 experiments...

PURPOSE: Mountain running races are becoming increasingly popular, although our understanding of the particular physiology associated with downhill running (DR) in trained athletes remains scarce. This study explored the cardiorespiratory responses to high-slope constant velocity uphill running (UR) and DR. METHOD: Eight endurance athletes performed a maximal incremental test and 2 15-min running bouts (UR, +15%, or DR, -15%) at the same running velocity (8.5 ± 0...

Kazuhiro Harada, Kouhei Masumoto, Narihiko Kondo
PURPOSE: Although it has been proposed that 1 spouse's health behaviors might correlate with the other spouse's health behavior among married couples, few studies have focused on sedentary behavior. This study examined whether objectively measured sedentary behavior and physical activity are correlated with each other and whether attachment to one's spouse moderates such correlations among middle-aged and older married couples. METHODS: Seventy-two couples participated in the survey...

SHAPE America - Society of Health and Physical Educators has targeted youth physical activity (PA) as 1 of its 4 goals within the 50 Million StrongTM campaign. Only 27.1% of youth met the target of all students (preK-12) participating in at least 60 min of PA that increases their heart rate enough to breathe hard at least some of the time for 7 days/week. Thus, improvements for child and adolescent engagement in PA need to be made now through 2029 and beyond. The need for these improvements warrants research related to PA and youth...
