Background: Only 17% of Latinas meet national physical activity (PA) guidelines for both moderate-to-vigorous aerobic and muscle-strengthening PA. Additional health benefits are derived from the combination of aerobic and muscle-strengthening PA (vs. aerobic alone), yet there is paucity in research on muscle-strengthening activity in Latinas. The…

Using a sample of healthy youth (n = 466, 10 to 18 yr), we report the predictive utility of vertical jump power (VJ Power, W) for predicting bone strength. We measured VJ Power using mechanography and an indicator of bone strength, i.e., height-adjusted total bone mineral content less head (TBLH BMC, g), using DXA. Growth curve models were used to…

Purpose: This systematic review aimed to identify studies evaluating the impact of high-intensity interval training when delivered in school and sports training. Methods: A systematic search of 10 databases (September 2019) identified 24 eligible studies (including children and/or adolescents 5-18 years and reporting cardiometabolic health and/or…

Purpose: To examine socialization experiences of physical educators who deliver strength and conditioning (S&C) programming, particularly the development of subjective theories, expertise, orientations, and perceived mattering. Methods: Thirty-one secondary school physical educators providing S&C instruction/supervision as part of required…

Purpose: To compare the effects of a single bout of eccentric cycling (ECC) and eccentric cycling with blood flow restriction (ECC[subscript BFR]) on the changes in cardio-metabolic demand and indirect markers of muscle damage in healthy men. Method: Twenty-one young men (24.0 ± 3.2 y) were randomly allocated in two groups to perform a 30-min…

We aimed to assess the test-retest reliability of five muscle strength and physical function tests in healthy children. Forty-one children (6--9 years) were tested three times 4-10 days apart. The test protocol included maximal isometric leg press, hand grip strength, squat jump, long jump, and a 30-sec sit-to-stand test (STST). When comparing…

Accurate determinations of individuals' one-repetition maximum (1RM) are critical when evaluating the effectiveness of an exercise intervention involving progressive resistance training (RT). Traditional ("bottom-up"; BT) testing methods involve progressions from low to maximal loads and are commonly used in clinical and laboratory…

The purpose of this study is to consider Superman's acts against impulse-momentum and conservation of momentum principles. Superheroes as fantasy fiction characters attract the attention of not only children and teenagers but also adults. Superheroes can be useful in explaining a phenomenon, as well as overcoming conceptual difficulties that may…

Background: The aim of this study was to examine the bidirectional longitudinal associations of several markers of fatness and physical fitness in adolescents with Down syndrome. Methods: This study comprised a total of 111 adolescents (41 females), aged from 11 to 20 years with complete data at the baseline. We had a drop-out of <10% from the…

Purpose: The purpose of this study was to investigate (a) time-dependent changes in muscle damage (MD) biomarkers, oxidative stress (OS) indices, and maximum strength performance; (b) the relationship between changes in maximum strength performance and changes in MD and OS indices; and (c) whether eccentric exercise-induced MD is related to OS.…

Due to lack of time in physical education class as well as the decreased amount of physical education class students have a week, students are not receiving adequate amounts of daily physical activity. This article describes a solution to this problem, by describing an after-school weightlifting program where students can learn how to do…

Purpose: This study was aimed to investigate the relationship between athletic performance and physiological characteristics in wheelchair basketball (WB) athletes with different classification scores. Methods: Twenty-six (24 male and 2 female) WB athletes were involved into the study. The participants were divided into two functional categories…

Objective: This study examined relationships between physical fitness, health behaviors, and occupational outcomes of university affiliates. Participants: 166 university affiliates of an American university (including students, faculty, and staff) participated between October 2018 and March 2020. Methods: Participants completed fitness…

The purpose of this study is to increase awareness among physical education teachers by analyzing the trends in reaching exercise programs on the Google platform during the coronavirus disease (COVID-19) pandemic. The exercise trends sought on the Google Trends platform between March 2020 and March 2021, when the pandemic was most intense, were…

Purpose: The fact that the sports branch that the athletes are interested in is included in the group of indoor and outdoor sports or team and individual sports can create differences in the motivation levels of the athletes. In this study, it was aimed to compare the motivation levels of team and individual athletes who do sports in Indoor and…
