50 Million Strong: The Contribution of Sports Coaching.

In 2015, the Society of Health and Physical Educators of America (SHAPE America) launched 50 Million Strong with goals of improving physical literacy, increasing physical activity levels, and encouraging lifelong physical activity among children by the year 2029. Not only are youth sports programs crucial to meeting 50 Million Strong goals, but it also requires the purposeful efforts of sport coaches, program administrators, researchers, coach educators, and coach developers. While it is encouraging that research on sport coaching topics appears to be growing, there is still much to learn about how to prepare coaches to provide quality sport experiences for their athletes.

The Susceptibles, Chancers, Pragmatists, and Fair Players: An Examination of the Sport Drug Control Model for Adolescent Athletes, Cluster Effects, and Norm Values Among Adolescent Athletes.

Although there are few high-profile cases of adolescent athletes being caught doping, up to a third of young athletes may dope. In order to generate a more accurate understanding of why adolescent athletes dope, it is important to validate models that help to explain this behavior. The aims of this study were 3-fold: firstly, to test the Sport Drug Control Model for Adolescent Athletes (SDCM-AA); secondly, to generate athlete profiles that would help quantify the proportion of athletes who are at risk of doping; and thirdly, to create norm values for the Adolescent Sport Doping Inventory (ASDI), which would allow national doping organizations, sporting organizations, and clubs to benchmark the scores of their athletes for key psycho-social variables linked to doping.

Muscular morphological adaptations of two whole-body high intensity interval training configurations.

Background: High-intensity intermittent training (HIIT) has increased in popularity due to being time-efficient mode of exercise. Previous HIIT studies have mainly focused on percentage of fat loss, fat mass loss, and weight loss. However, enhancing muscle protein synthesis induced by HIIT that results in muscular morphological adaptations is a potential benefit of HIIT.

Physiological Demands of Extreme Obstacle Course Racing: A Case Study.

Obstacle course races are a popular source of recreation in the United States, providing additional challenges over traditional endurance events. Despite their popularity, very little is known about the physiological or cognitive demands of obstacle course races compared to traditional road races. The purpose of this study was to investigate the physiological effects of participation in an extreme obstacle course race.

The development and validation of the Adolescent Sport Drug Inventory (ASDI) among athletes from four continents.

A significant barrier to understanding the psychosocial antecedents of doping use among adolescent athletes is the lack of valid measures. In order to address this issue, the first aim of this paper was to develop and validate the Adolescent Sport Drug Inventory (ASDI) among adolescent athletes from Asia, Europe, North America, and Oceania. The second aim was to assess the construct validity of the ASDI.

Impact of Positive and Negative Motivation and Music on Jump Shot Efficiency among NAIA Division I College Basketball Players.

The objective of this study was to determine whether music, positive feedback, and/or negative feedback impacted jump shooting performance in NAIA Division I male and female basketball players. Using a cross-over design, participants (N=20) took 50 shots from 15 feet and 50 shots from the 3-point line under four conditions (silence, music, positive feedback, negative feedback). The number of shots made were recorded and a one-way ANOVA was used to determine differences between gender.

Self-Selected Motivational Music on the Performance and Perceived Exertion of Runners.

Clark, JC, Baghurst, T, and Redus, BS. Self-selected motivational music on the performance and perceived exertion of runners. J Strength Cond Res 35(6): 1656-1661, 2021-Music is used by athletes and exercisers to improve performance outcomes, but it is less known whether its properties can enhance performance at maximal intensity.

Impact of cognitive fatigue on gait and sway among older adults: A literature review.

Cognitive fatigue is an alteration in central nervous system (CNS) processing due to prolonged performance of mentally demanding tasks. Decreased gait speed and increased stride length variability have been noted in cognitively fatigued older adults (≥ 65 years). Further, cognitive fatigue may weaken the visual, vestibular, and proprioceptive systems of the CNS, contributing to increased postural sway.

Practical Treatments Considering the Role of Sociocultural Factors on Problem Gambling.

Reviews of problem gambling (PG) literature increasingly recognize the ways in which different ethnic groups are affected by gambling behaviors, yet discourse, which considers sociocultural factors within PG, remains limited. Literature on this topic is influenced by large inconsistencies amongst research studies, overlapping terminology, and variability in the validity of research studies, making conclusions difficult to draw. Despite these discrepancies, this paper explores how sociocultural factors influence PG among diverse cultural groups and provides specific practical implications for treating PG disorders in culturally diverse populations.

Comparing current fitness center members' perceptions of the motivational climate with non-members.

Researchers using an achievement goal theory and caring climate framework have highlighted the connection between fitness center members' climate perceptions and their exercise motivation. However, much of what is known comes from current members, with little known about former and non-members' perceptions. The purpose of this study was to compare current, former, and non-members' perceptions of the motivational climate of a university campus fitness facility.

Preschool motor development predicting high school health-related physical fitness: a prospective study.

To address the obesity epidemic there is an increasing effort to emphasize physical activity and fitness in adolescence as opposed to fundamental motor skills. However, what effect this might have on health-related fitness is unclear. This study sought to determine the degree to which motor development competencies in preschool could predict high school fitness.

Effect of handedness on gross motor skill acquisition in a novel sports skill task.

The purpose of this study was to examine differences in performance and form scores between left and right-handers who observed a demonstration with their non-dominant hand. A lacrosse shot was demonstrated to 69 college-aged participants with equal representations on gender and handedness. Half of each group saw a left-handed demonstration while the other half saw a right-handed demonstration.

An examination of stress in college students over the course of a semester.

The purpose of this study was to determine whether differing stress reduction interventions could alter stress levels experienced by male and female college students from the beginning to the end of a semester. Components of stress examined included overall perceived stress, test anxiety, and personal burnout. Participants (N = 531) were part of courses that during the course of a 16-week semester focused specifically on cognitive-behavioral stress management, cardiovascular fitness, generalized physical activity, or a control with no intervention.

Characteristics of muscle dysmorphia in male football, weight training, and competitive natural and non-natural bodybuilding samples.

The purpose of this study was to identify differences in traits associated with muscle dysmorphia between collegiate football players (n=66), weight trainers for physique (n=115), competitive non-natural bodybuilders (n=47), and competitive natural bodybuilders (n=65). All participants completed demographic questionnaires in addition to the Muscle Dysmorphia Inventory (Rhea, Lantz, & Cornelius, 2004). Results revealed a significant main effect for group, and post hoc tests found that the non-natural bodybuilding group did not score significantly higher than the natural bodybuilding group on any subscale except for Pharmacological Use.

Change in sociocultural ideal male physique: An examination of past and present action figures.

The physical dimensions of five contemporary action figures were measured and compared to their original counterparts to determine whether their physiques have become more muscular from their original designs. The circumferences of the neck, chest, arm, forearm, waist, thigh, and calf were measured three separate times using a Scale Master II model 6325. The mean score was then used in subsequent analyses.

Preadolescent male perceptions of action figure physiques.

This study investigated the preference and reasoning of 176 preadolescent and adolescent males when presented with original and current action figures that had statistically different physiques. Current action figures were perceived as significantly more muscular and healthier. Participants also preferred to resemble current action figures citing muscularity and size for their preference.
