Indicators of physical activity and nutritional status among children and adolescents in Zimbabwe: Findings from three global matrix initiatives J. Exerc. Sci. Fit. (IF 2.8) Pub Date : 2023-02-09 Taru Manyanga, Daga Makaza, Nyaradzai E. Munambah, Carol Mahachi, Caroline Mavingire, Tholumusa F. Mlalazi, Matilda Mukaro, Tonderayi M. Matsungo
Background Regular physical activity is associated with several benefits among children and adolescents. Globally, only limited surveillance data, collected using harmonized approaches to accurately compare levels of physical activity among children and adolescents are available. Through its Global Matrix initiatives, Active Health Kids Global Alliance provides an opportunity for participating cou

Effects of 12-week combined training versus high intensity interval training on cardiorespiratory fitness, body composition and fat metabolism in obese male adults J. Exerc. Sci. Fit. (IF 2.8) Pub Date : 2023-02-01 Mattia D'Alleva, Filippo Vaccari, Francesco Graniero, Nicola Giovanelli, Mirco Floreani, Federica Fiori, Michela Marinoni, Maria Parpinel, Stefano Lazzer
Background /Objectives: A weekly combination of a high volume of moderate-intensity continuous training (MICT) with a low volume of high-intensity interval training (HIIT) provides important improvements in body composition and physical capacities in individuals with obesity. However, previous studies did not determine the weekly proportions of HIIT and MICT a priori. This study aimed to investigate

Acute cardiovascular responses to unilateral bicep curls with blood flow restriction J. Exerc. Sci. Fit. (IF 2.8) Pub Date : 2023-01-18 Xiangyu Zheng, Samuel A.E. Headley, Stephen A. Maris, Daniel M. Smith
A consensus on the acute cardiovascular responses to low intensity (LI) resistance exercise (RE) combined with blood flow restriction (BFR) has not yet been reached. This study was designed to compare acute cardiovascular responses to a single bout of LIRE, high intensity (HI) RE, and LIRE with BFR in physically active young males. Participants completed 3 RE sessions in random order, where each session

Associations between 24-h movement behaviours and BMI in Chinese primary- and middle- school students J. Exerc. Sci. Fit. (IF 2.8) Pub Date : 2023-01-17 Huan Chen, Li-juan Wang, Fei Xin, Guo Liang, Yu-lan Zhou
Purposes This cross-sectional study aimed to examine the associations between the 24-h movement behaviours and body mass index (BMI) of students from China by using compositional data analysis. Methods A total of 389 students aged 6–16 years participated in this study. Accelerometers were used to measure moderate-to-vigorous physical activity (MVPA), light-intensity physical activity (LPA), sedentary

Unsupervised cluster analysis reveals distinct subgroups in healthy population with different exercise responses of cardiorespiratory fitness J. Exerc. Sci. Fit. (IF 2.8) Pub Date : 2022-12-31 Lin Xie, Bo Gou, Shuwen Bai, Dong Yang, Zhe Zhang, Xiaohui Di, Chunwang Su, Xiaoni Wang, Kun Wang, Jianbao Zhang
Background Considerable attention has been paid to interindividual differences in the cardiorespiratory fitness (CRF) response to exercise. However, the complex multifactorial nature of CRF response variability poses a significant challenge to our understanding of this issue. We aimed to explore whether unsupervised clustering can take advantage of large amounts of clinical data and identify latent

Physical literacy in Europe: The current state of implementation in research, practice, and policy J. Exerc. Sci. Fit. (IF 2.8) Pub Date : 2022-12-30 Johannes Carl, Anna S. Bryant, Lowri C. Edwards, Gillian Bartle, Jens E. Birch, Efstathios Christodoulides, Arunas Emeljanovas, Andreas Fröberg, Joseph Gandrieau, Barbara Gilic, Ivo van Hilvoorde, Peter Holler, Teodora M. Iconomescu, Johannes Jaunig, Ida Laudanska-Krzeminska, Suzanne Lundvall, Kristine De Martelaer, João Martins, Brigita Mieziene, Maria Mendoza-Muñoz, Peter Elsborg
Background/objective The holistic concept of physical literacy (PL) embraces different person-centered qualities (physical, cognitive, affective/psychological) necessary to lead physically active lifestyles. PL has recently gained increasing attention globally and Europe is no exception. However, scientific endeavors summarizing the current state of PL in Europe are lacking. Therefore, the goal of

Acute effects of jaw clenching while wearing a customized bite-aligning mouthguard on muscle activity and force production during maximal upper body isometric strength J. Exerc. Sci. Fit. (IF 2.8) Pub Date : 2022-12-26 Adrià Miró, Bernat Buscà, Jordi Arboix-Alió, Pol Huertas, Joan Aguilera-Castells
Background/objectives The possible mechanisms supporting the relationship between the masticatory and the musculoskeletal systems have been recently investigated. It has been suggested that jaw clenching promotes ergogenic effects on prime movers through the phenomenon of concurrent activation potentiation (CAP). The purpose of this study was to analyse the effects of jaw clenching and jaw clenching

Effects of multicomponent exercise training on muscle oxygenation in young and older adults J. Exerc. Sci. Fit. (IF 2.8) Pub Date : 2022-12-08 Tai-You Lin, Jia-Jin J. Chen, Linda L. Lin, Wei-Tsun Ou Yang, Meng-Yu Chen, Yueh-Chang Tsai
Objective Though multicomponent exercise training was found beneficial in improving the physical functionality, the effects of multicomponent exercise training on muscle oxygenation are still unclear. The purpose of this study was to investigate the effects of multicomponent exercise training on muscle oxygenation in young and older participants. Methods In this study, 17 young adults (Y) and 18 healthy
