Purpose: This study aimed to investigate how teachers' socialization experiences influence their perceptions of and responses to bullying. Methods: Thirty in-service physical education teachers were recruited to participate. One semi-structured, individual interview was conducted with each participant lasting approximately 60 minutes. Data analysis employed inductive and deductive techniques. Results: Two themes emerged that described teachers' perceptions of and responses to bullying. These themes included: (a) socialization experiences and socializing agents influence teachers' perceptions and behaviors in relation to bullying, and (b) teachers have developed strategies to address bullying but also experience significant challenges...

Purpose: The aim was to study if aerobic capacity varies during different phases of the menstrual cycle (MC) in endurance-trained female athletes. Methods: Ten endurance-trained eumenorrheic women performed a submaximal test followed by an incremental test until exhaustion three times during one MC, early follicular phase (EFP), late follicular phase (LFP), and midluteal phase (MLP). During the submaximal test, the respiratory exchange ratio (RER) and utilization of fat and carbohydrates were analyzed; and, during the incremental test, VO2 peak , maximal heart rate, utilization of fat and carbohydrates, and RER were analyzed...

Purpose : This study is aimed to determine specific bilateral lower extremity motor performances and coordination patterns in soccer players with healthy controls using the bilateral force control paradigm. We hypothesized that soccer players would show more advanced bilateral force control performances than untrained controls. Methods : Participants were 13 university soccer players and 13 healthy controls. Each group performed bilateral ankle dorsiflexion force control tasks across two vision conditions (i...

Purpose : We investigated youth volleyball players' perception of affordances for different types of serves. Methods : Participants were separated into Less Experienced ( n  = 13, maximum of 3 years of competitive volleyball experience) and More Experienced ( n  = 11, minimum of 4 years of competitive volleyball experience) groups. In the Sideline Condition, participants were asked to report the narrowest gap, relative to either the left or right sideline, into which they could serve the ball...

Aim : To understand mean (WCSmean ) and peak (WCSpeak ) worst case scenarios within training and game play in male professional soccer. Methods : Thirty-one ( n  = 31) first team players were monitored across 37 matches and 14 MD-3 sessions. Playing status was distinguished, football drills analyzed, and performance explored in long-period: >6 days, moderate-period: 5-6 days, and congested-period: ≤4 days. Relative total distance (TD), high-speed running distance (HSRD, >19...

Purpose: Despite the accuracy of heart rate (HR) as an indicator of the aerobic engagement has been evaluated in several intermittent on-court activities, its validity as an oxygen uptake (<mml:math xmlns:mml="https://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msub><mml:mover><mml:mi>V</mml:mi><mml:mo>˙</mml:mo></mml:mover><mml:mrow><mml:mrow><mml:msub><mml:mi>O</mml:mi><mml:mn>2</mml:mn></mml:msub></mml:mrow></mml:mrow></mml:msub></mml:mrow></mml:math>) indicator during shuttle running over short paths remains uncertain...

Purpose: This study aimed to examine the effect of self-controlled video feedback on the learning of tactical motor skills in tennis, and additionally, whether this was affected by learners' self-efficacy and self-regulative skills. Method: Twenty-three intermediately skilled tennis players were assigned to either a self-controlled group that was provided video feedback on request or a yoked group that received an identical, externally controlled video feedback schedule. In three training sessions participants practiced serve and volley play...

Purpose: The aim of the present study was to investigate the effects of acute caffeine supplementation on the performance during a session of resistance training alone (RT) or in combination with aerobic training (i.e. concurrent training; CT). Method: Fourteen resistance-trained men (23.1 ± 4.2 years) were recruited and performed both RT and CT under three different conditions: control (CONT), placebo (PLA), and caffeine (CAF; 6 mg.kg-1 ) for a total of six experimental conditions...

Purpose: We investigated the effects of pre-exercise voluntary hyperventilation and the resultant hypocapnia on metabolic and cardiovascular responses during and after high-intensity exercise. Methods : Ten healthy participants performed a 60-s cycling exercise at a workload of 120% peak oxygen uptake in control (spontaneous breathing), hypocapnia and normocapnia trials. Hypocapnia was induced through 20-min pre-exercise voluntary hyperventilation. In the normocapnia trial, voluntary hyperpnea was performed with CO2 inhalation to prevent hypocapnia...

Public health guidelines for resistance training emphasize a minimal effective dose intending for individuals to engage in these behaviors long term. However, few studies have adequately examined the longitudinal time-course of strength adaptations to resistance training. Purpose: The aim of this study was to examine the time-course of strength development from minimal-dose resistance training in a large sample through retrospective training records from a private international exercise company. Methods: Data were available for analysis from 14,690 participants (60% female; aged 48 ± 11 years) having undergone minimal-dose resistance training (1x/week, single sets to momentary failure of six exercises) up to 352 weeks (~6...

Purpose : The aim was to analyze the differences between wheelchair basketball players with Spinal Cord Injury (SCI) and without Spinal Cord injury (Non-SCI) in psycho-physiological response and neuromuscular fatigue in a series of small-sided games (SSG). Methods : Thirteen high-level wheelchair basketball male players (age 28.8 ± 9.2 years, body mass 75.9 ± 11.3 kg) participated in four versus four SSG once a week for five consecutive weeks. Absolute and relative heart rate (HR) during SSG and muscular and respiratory perceived exertion (RPEmus and RPEres), tympanic temperature, and acceleration capacity were recorded at the end of each SSG...

Purpose: This study set out to identify the extent of the relationships between subsections of the Movement Assessment Battery for Children 2nd Edition - MABC2 (manual dexterity, aiming and catching, and balance) to PA, CRF and BMI in adolescents. Methods: Height, BMI, the MABC2, a 20m shuttle run test and wrist-worn accelerometery PA levels (mins) were measured. Multivariable linear regression models, adjusting for sex, height and BMI were used to assess the relationship of the three subsections of the MABC2 with PA, CRF and BMI...

Purpose: Based on person-context interaction, situational interest (SI) has been used to interpret students' motivation in task engagement. Through two consecutive studies, the purpose of this research was to investigate the roles of forms of dyads (self-selected vs. ability), feelings of relatedness and perceived competence in eliciting students' SI within the reciprocal teaching style. Method: The first study examined the role of dyad composition to determine how to group students to elicit high SI (self selected vs...
