The application of strength and conditioning principles and concepts are built into the national standards and grade-level outcomes; however, the prevailing FITT formula does not meet the needs of students today. Instead of one standard workout program for all, students need to learn about a nonlinear, or undulating, program that provides options…

Purpose: The purpose was to examine secondary physical education teachers' strength and conditioning (SC) knowledge and evaluate associations between SC teaching role, professional preparation, and development. Method: A knowledge survey was developed/validated and distributed to 2,189 middle/high school teachers, with 605 providing complete data.…

Background: Data missingness can bias interpretation and outcomes resulting from data use. We describe data missingness in the longest-standing US-based youth fitness surveillance system (2006/07-2019/20). Methods: This observational study uses the New York City FITNESSGRAM (NYCFG) database from 1,983,629 unique 4th-12th grade students (9,147,873…

Purpose: The aim of this study was to examine the relationships of clinical measures of lingual and perihyoid strength with displacement swallowing kinematics and swallowing safety in a heterogenous group of dysphagic adults. Method: A retrospective analysis was completed of videofluoroscopic swallow studies of consecutive dysphagic outpatient…

The purpose was to evaluate the intra- and inter-session reliability of hip isometric strength assessment using a frame-stabilized dynamometer (FSD) and to compare the results in the hip adduction (ADD) and abduction (ABD) strength assessment using handheld dynamometer (HHD). Twenty participants (24.2 [2.6] years, 69.3 [10.0] kg) underwent testing…

The aim of this study was to examine the effect of core exercises on swimmers Functional Movement Screen (FMS) test scores and swimming performance. A total of 32 volunteer children aged 12-15 participated in this study. Participants were separated into 3 main groups: the control group (CG; N = 10) that did not perform any exercises, the swimming…

Swing movements and muscle strength are essential for mastering badminton techniques. Traditionally, students learn badminton through their instructor's physical demonstration, verbal instructions, and small group activities. To enhance students' learning experience and assist badminton instructors more effectively, this study proposes an…

The purpose of this study was to determine the associations of device-based assessments of physical activity (PA) and health-related fitness (HRF) with gross motor skills (GMS) in preschool-aged children. Participants were 3- to 5-year-old children (N = 316; 49.6% female) who participated in the 2012 National Youth Fitness Survey. GMS was assessed…

This study assessed whether trunk flexor and extensor strength were predictors of time to stability (TTS) and center of pressure (CoP) during hop and hold tasks in children. Seventeen boys (age, 10.1 ± 1.6 years; height, 1.45 ± 0.11 m; mass, 26.7 ± 7.83 kg) undertook isokinetic strength assessments of concentric and eccentric trunk…

Background: This study aimed to investigate the association between violent sexual victimization and muscle-building exercise among adolescents. Methods: Cross-sectional data from the 2019 National Youth Risk Behavior Survey (N = 8408) were analyzed. Two indicators of non-dating-related sexual violence (lifetime, past 12 months), along with one…

Purpose: To examine the associations between muscular fitness (MF) and body composition. Method: MF was assessed with three tests of FitnessGram test battery. Total body fat percentage (BF%), abdominal fat percentage (AF%) and fat-free mass (FFM) were measured by dual-energy X-ray absorptiometry (DXA). The IOTF body mass index (BMI) cut-offs were…

Purpose: The purpose of this study was to investigate the effects of tongue-strengthening exercise (TSE) on tongue strength and effortful swallowing pressure in young healthy adults. Method: Thirteen young healthy volunteers (six men, seven women; M[subscript age] = 20.5 ± 0.5 years) performed 8 weeks of isometric TSE 3 days per week. A tongue…

The FitnessGram program has prioritized the use of evidence-based, criterion-referenced standards to advance health-related fitness assessments in physical education. The Institute of Medicine (IOM) highlighted the importance of strength and power for youth fitness assessment and surveillance. The report specifically recommended the use of…

The purpose of this study was to examine exercise preferences of college students (CS), and explore potential gender differences to inform interventions. Participants (N = 187, 18-25 years) completed an online survey. Descriptive statistics were conducted to characterize preferences for exercise type and mode of delivery, followed by X[superscript…

This study aimed to assess intra- and inter-visit reliability of a novel EasyForce dynamometer for assessment of maximal strength in knee extension and flexion, and hip abduction and adduction tasks. Young healthy participants (n = 50; 25 males, 25 females; age: 23.4 ± 2.1 years) were measured for maximal joint torque with EasyForce dynamometer…
