Canabrava, Karina L. R.; Faria, Fernanda R.; de Lima, Jorge R. P.; Guedes, Dartagnan P.; Amorim, Paulo R. S. – Research Quarterly for Exercise and Sport, 2018
Purpose: This study aimed to compare the energy expenditure and intensity of active video games to that of treadmill walking in children and adolescents. Method: Seventy-two boys and girls (aged 8-13 years) were recruited from local public schools. Energy expenditure and heart rate were measured during rest, during 3-km/hr, 4-km/hr, and 5-km/hr…

Vieira, Luiz H. P.; Cunha, Sérgio A.; Moraes, Renato; Barbieri, Fabio A.; Aquino, Rodrigo; Oliveira, Lucas de P.; Navarro, Martina; Bedo, Bruno L. S.; Santiago, Paulo R. P. – Research Quarterly for Exercise and Sport, 2018
Purpose: The purpose of this study was to compare the kicking performance of young soccer players in the U9 to U20 age groups. Method: Three hundred and sixty-six Brazilian players were evaluated on an official pitch using three-dimensional kinematics to measure (300 Hz) ball velocity (V[subscript ball]), foot velocity (V[subscript foot]),…

Costa, Rochelle Rocha; Pilla, Carmen; Buttelli, Adriana Cristine Koch; Barreto, Michelle Flores; Vieiro, Priscila Azevedo; Alberton, Cristine Lima; Bracht, Cláudia Gomes; Kruel, Luiz Fernando Martins – Research Quarterly for Exercise and Sport, 2018
Purpose: This study aimed to investigate the effects of water-based aerobic training on the lipid profile and lipoprotein lipase (LPL) levels in premenopausal women with dyslipidemia. Method: Forty women were randomly assigned to: aquatic training (WA; n = 20) or a control group (CG; n = 20). The WA group underwent 12 weeks of water-based interval…

Fortes, Leonardo S.; Nascimento-Júnior, José R. A.; Mortatti, Arnaldo L.; de Lima-Júnior, Dalton Roberto Alvas Araújo; Ferreira, Maria E. C. – Research Quarterly for Exercise and Sport, 2018
It seems that dehydration may impair decision-making performance in athletes. Purpose: This study aimed to investigate the influence of dehydration on passing decision-making performance in soccer players. Method: Participants were 40 male soccer players (M[subscript age] = 22.3 ± 2.3 years) who agreed to participate in the study and were randomly…

Luguetti, Carla; Oliver, Kimberly L.; Dantas, Luiz Eduardo Pinto Basto Tourinho; Kirk, David – Research Quarterly for Exercise and Sport, 2017
Purpose: This study was a 2-phase activist research project aimed at co-creating a prototype pedagogical model for working with youth from socially vulnerable backgrounds in a sport context. This article addresses the learning aspirations (learning outcomes) that emerged when we created spaces for youth to develop strategies to manage the risks…

da Cruz, Carlos Janssen Gomes; Molina, Guilherme Eckhardt; Porto, Luiz Guilherme Grossi; Junqueira, Luiz Fernando, Jr. – Research Quarterly for Exercise and Sport, 2017
Purpose: In a cross-sectional study design, we evaluated the resting heart rate (HR[subscript baseline]) and exercise and postexercise stress test-related chronotropic responses in male practitioners of recreational ballroom dancing (BD; n = 25, M[subscript age] = 26.6 ± 6.1 years) compared to a control group of insufficiently active nondancers…

Antunes, Amanda H.; Alberton, Cristine L.; Finatto, Paula; Pinto, Stephanie S.; Cadore, Eduardo L.; Zaffari, Paula; Kruel, Luiz F. M. – Research Quarterly for Exercise and Sport, 2015
Purpose: Maximal tests conducted on land are not suitable for the prescription of aquatic exercises, which makes it difficult to optimize the intensity of water aerobics classes. The aim of the present study was to evaluate the maximal and anaerobic threshold cardiorespiratory responses to 6 water aerobics exercises. Volunteers performed 3 of the…

dos Santos Cunha, Giovani; Sant'anna, Marcelo Morganti; Cadore, Eduardo Lusa; de Oliveira, Norton Luis; dos Santos, Cinara Bos; Pinto, Ronei Silveira; Reischak-Oliveira, Alvaro – Research Quarterly for Exercise and Sport, 2015
Purpose: The purpose of this study was to investigate the physiological adaptations of resistance training (RT) in prepubertal boys. Methods: Eighteen healthy boys were divided into RT (n = 9, M[subscript age] = 10.4 ± 0.5 years) and control (CTR; n = 9, M[subscript age] = 10.9 ± 0.7 years) groups. The RT group underwent a resistance training…

de Paula Asa, Sabrina Kyoko; Santos Melo, Mara Cristina; Piemonte, Maria Elisa Pimentel – Research Quarterly for Exercise and Sport, 2014
Purpose: We sought to compare the effects of physical practice (PP) and mental practice (MP) on the immediate and long-term learning of the finger-to-thumb opposition sequence task (FOS) in children; in addition, we investigated the transfer of this learning to an untrained sequence of movements and to the contralateral untrained hand. Method:…

Purpose: To quantify creatine kinase (CK) activity changes across time following an acute bout of whole-body vibration (WBV) and determine the association between changes in CK activity and jumping performance. Method: Twenty-six elite young basketball players were assigned to 3 groups: 36-Hz and 46-Hz vibration groups (G36 and G46, respectively)…

In this study, we analyzed the relationship between running economy (RE) and biomechanical parameters in a group running at the same relative intensity and same absolute velocity. Sixteen homogeneous male long-distance runners performed a test to determine RE at 4.4 m.s[superscript -1], corresponding to 11.1% below velocity at the ventilatory…

Okazaki, Fabio H. A.; Keller, Birgit; Fontana, Fabio E.; Gallagher, Jere D. – Research Quarterly for Exercise and Sport, 2011
In sports, the relative age effect (RAE) refers to performance disadvantages of children born late in the competition year compared to those with birthdays soon after the cutoff date. This effect is derived from age grouping, a strategy commonly used in youth sport programs. The purpose of age grouping is to decrease possible cognitive, physical,…

Chiviacowsky, Suzete; Wulf, Gabriele; Laroque de Medeiros, Franklin; Kaefer, Angelica; Tani, Go – Research Quarterly for Exercise and Sport, 2008
The purpose of the present study was to examine whether the learning benefits of self-controlled knowledge of results (KR) would generalize to children. Specifically, the authors chose 10-year-old children representative of late childhood. The authors used a task that required the children to toss beanbags at a target. One group received KR…

Chiviacowsky, Suzete; Wulf, Gabriele; de Medeiros, Franklin Laroque; Kaefer, Angelica; Wally, Raquel – Research Quarterly for Exercise and Sport, 2008
The purpose of the present study was to examine whether learning in 10-year-old children--that is, the age group for which the Chiviacowsky et al. (2006) study found benefits of self-controlled knowledge of results (KR)--would differ depending on the frequency of feedback they chose. The authors surmised that a relatively high feedback frequency…
