The purpose of this article is to provide recommendations as to how teacher content knowledge can be improved to enhance the efficacy of RT programs for secondary PE students. We offer four recommendations including 1) Embed RT for adolescents content knowledge within physical education teacher education (PETE) programs, 2) Professional…

The Cognitive Load Theory (CLT) aims to foster learning productively under optimal cognitive loads. Students across all ages and stages of learning have limited capacity due to the human brain's functionality. Therefore, an effective learning design allows for knowledge acquisition that will minimize the loading effect on the working memory and…

Background: Individuals with intellectual and developmental disabilities tend to engage in low levels of physical activity, which puts them at risk for chronic health conditions, poor balance and gait difficulties. Nordic walking could improve gait, balance, strength, endurance and respiratory function while enjoying nature. Method: Thirty-four…

Purpose: To estimate temporal trends in broad jump performance for United States youth, a marker of muscular fitness and health. Method: Electronic databases, topical systematic reviews, and personal libraries were systematically searched for studies reporting descriptive standing broad jump data for apparently healthy United States youth (age…

Sport coaches can agree that various levels of practice and play contribute significantly to the overall development of a young athlete. Coaches of young athletes need to also address issues related to strength and conditioning as part of the developmental cycle. Unfortunately, many sport coaches are not well trained in the science related to…

Purpose: The aim of this study was to propose field-based tests to estimate the anaerobic power of wheelchair basketball athletes. Methods: Eleven lower class wheelchair basketball players performed the Wingate test (WT) and two field-based tests (repeated sprints) of 15 (S-15) and 20 (S-20) meters. The WT provides data in Watts (W). The S-15 and…

Background: The "Physical Activity Guidelines for Americans, 2nd edition" ("PAGA2") is an evidence-based policy for physical activity. The PAGA2 addresses sedentary behavior, promotes physical activity, and elaborates on improved health outcomes associated with physical activity. The Promoting Physical Activity for Americans…

We designed grip strength standards for youth by back-extrapolating cutpoints based on weakness at age 65. Existing standards, based on insufficient bone mineral content (BMC), were also compared in a nationally representative sample. Altogether, 6837 participants (n = 2199 [less than or equal to] 18.9 years of age) from the National Health and…

This study evaluated test-equating methods to enable comparisons and conversions between the vertical jump (VJ) and standing long jump (SLJ) tests. A total of 528 youth (280 males) performed VJ and SLJ, and their scores were randomly split as the calibration (C) sample (n = 478) and cross-validation (CV) sample (n = 50). SLJ scores of the C sample…

Purpose: The purpose of this study was to investigate the impact on health-related fitness resulting from COVID-19 lockdowns on male high school students in Melbourne, Australia. Method: A total of 146 students completed fitness testing in February and retesting in November following 7 months of remote learning. Fitness tests conducted were 20-m…

The purpose of this research is: (a) to compare the dominant and non-dominant leg isokinetic strength and balance, (b) to compare the balance applied on the same side to different directions and isokinetic strength applied to the same side at different angular velocities and (c) to examine the relationship between the balance and isokinetic…

Knee flexor and extensor muscular assessment via isokinetic dynamometry is common practice and established in the research literature. However, reporting assessment methodology regarding reciprocal and nonreciprocal movements is often vague or absent. Such methodological issues are crucial for accurate assessments. Therefore, knee extensor and…

To assess the acute effect of strength exercises combined with EMS on blood flow and muscle stiffness using SMI and SWE. This prospective study included 20 participants. Subjects were divided into groups base on calisthenics strength training with EMS and without EMS. Rectus femoris (RF) blood flow was measured at rest and post-exercise with the…

Many professionals use the handheld dynamometers (HHDs) to assess isometric strength. This study aimed to evaluate the validity, reliability, and sensitivity to change of a DiCI (a new HHD) for the strength measurement of knee and hip muscles and their ratios. Thirty-five recreational athletes completed quadriceps, hamstring, and hip adductors and…

Purpose: This study compared the acute effects of two different resistance training methods on heart rate variability, blood pressure, and rating of perceived exertion in patients with liver cirrhosis. Methods: Ten patients with Child-Pugh A (seven women and three men) participated in two experimental sessions, in random order: The traditional set…
