The physical fitness course is a mandatory subject for undergraduate students at Universitas Negeri Surabaya, Indonesia. However, there is limited physical activity possibly performed during the COVID-19 pandemic. Furthermore, conventional physical fitness tests and measurements could not be conducted in a conventional way. This study aimed to…

This article reflects on an instructor's experience of incorporating an optional assignment in a theology class wherein students are invited to learn a new athletic skill, journal while doing so, and then theologically reflect on their experience. It begins with the instructor making a case for the need to bring the body back into the classroom.…

Purpose: To analyze the contribution of physical measures and external load in the match-based internal load of elite soccer players. Methods: Twenty-three elite soccer players (n = 23, age 26.69 ± 3.93 years, body mass 78.04 ± 5.03 kg, height 178.04 ± 5.19 cm, body fat 10.98 ± 1.25%) from a first division soccer team of the Brazilian Championship…

This study aimed to research the effect of dry-land quickness training for 14-16 years old male swimmers on 50 m freestyle swimming performance. 30 volunteer male athletes and 10 volunteer males in the same age group who do not sport participated in this study. Athletes were grouped who took swimming training as experiment1 (E1), experiment2 (E2)…

Many factors determine success in football. But the most important of these are the physical and physiological variables that determine the performance of football players. Meeting these physical and physiological needs is also based on training methods prepared following branch-specific neural, muscular, and metabolic parameters. In football, for…

Purpose: The aim of this study was to examine the short and long-term effects of a simple strength training program on muscle injury prevention in soccer players. Methods: Twenty-seven U-19 elite male soccer players participated in the study. The investigation was conducted over two consecutive and similar seasons (e.g., the same staff, players,…

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: 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…

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: 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.…

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…
