Julio, Ursula F.; Panissa, Valéria L. G.; Cury, Rubiana L.; Agostinho, Marcus F.; Esteves, João V. D. C.; Franchini, Emerson – Research Quarterly for Exercise and Sport, 2019
Purpose: This study compared the energy system contributions and relationship between mechanical and energy system variables in upper and lower body Wingate tests (WAnT) in judo athletes. Method: Eleven male judo athletes (18 ± 1 years, 174.3 ± 5.3 cm, 72.6 ± 9.9 kg, 11.8 ± 1.7% body fat) attended two laboratory sessions to perform two WAnT (upper…

Araújo, Jaqueline A.; Queiroz, Marilene G.; Dias, André R. L.; Sousa, Laila C. J. L.; Arsa, Gisela; Cambri, Lucieli T. – Research Quarterly for Exercise and Sport, 2019
Purpose: To evaluate whether excess body mass influences the heart rate variability (HRV) indexes at rest, and to correlate adiposity indicators and the aerobic fitness with cardiac autonomic variables in metabolically healthy young adults. Method: In all, 41 untrained males (M[subscript age] = 21.80, SD = 2.14 years), 14 normal weight…

Raimundo, João A. G.; Turnes, Tiago; de Aguiar, Rafael A.; Lisbôa, Felipe D.; Loch, Thiago; Ribeiro, Guilherme; Caputo, Fabrizio – Research Quarterly for Exercise and Sport, 2019
Purpose: Metabolic perturbation and VO[subscript 2] on-kinetics are potential modifiers of fatigue and vary in importance depending on the exercise task. Thus, performance fatigability during high-intensity exercise seems to be exercise mode dependent, affecting tolerance in the severe domain. However, the effects of exercise mode on severe domain…

Cicone, Zackary S.; Holmes, Clifton J.; Fedewa, Michael V.; MacDonald, Hayley V.; Esco, Michael R. – Research Quarterly for Exercise and Sport, 2019
Purpose: Maximal heart rate (MHR) is an important physiologic tool for prescribing and monitoring exercise in both clinical and athletic settings. However, prediction equations developed in adults may have limited accuracy in youth. The purpose of this study was to systematically review and analyze the available evidence regarding the validity of…

Yanovich, Ran; Ketko, Itay; Muginshtein-Simkovitch, Jeni; Yanovich, Einat; Eliyahu, Uri; Fleischmann, Chen; Atias-Varon, Danit; Waissengrin, Barliz; Makranz, Chen; Heled, Yuval – Research Quarterly for Exercise and Sport, 2019
Purpose: Heat intolerance (HI) is determined in the Israel Defense Force according to a heat tolerance test (HTT) before returning to duty after an exertional heat stroke (EHS) event. Recently, increased numbers of female combatants resulted in an increased number of EHS cases among women and a higher percentage of heat intolerance (HI)…

Morris, Cody E.; Wessel, Paige A.; Tinius, Rachel A.; Schafer, Mark A.; Maples, Jill M. – Research Quarterly for Exercise and Sport, 2019
Purpose: The purpose of this study was to evaluate the agreement of five commercially available accelerometers in estimating energy expenditure while performing an acute bout of high-intensity functional training (HIFT). Methods: Participants (n = 47; average age: 28.5 ± 11.6 years) consisted of recreationally active, healthy adults. Each…

Gil-Rey, Erreka; Maldonado-Martín, Sara; Gorostiaga, Esteban M. – Research Quarterly for Exercise and Sport, 2019
Purpose: The aim of this study was to compare the widely used accelerometer activity cut-points derived from the absolute moderate intensity recommendation (3-6 METs), with relative intensity cut-points according to maximal cardiorespiratory fitness (46%-63% VO[subscript 2max]) and to individual lactate thresholds (LT1 and LT2) in postmenopausal…

Dokumaci, Bircan; Hazir, Tahir – Research Quarterly for Exercise and Sport, 2019
Purpose: This study investigated the effects of the menstrual cycle on running economy (RE). Method: Eleven eumenorrheic female athletes (mean age: 21.18 [plus or minus] 3.65 years, height: 170.2 [plus or minus] 6.6 cm, VO[subscript 2]max: 49.25 [plus or minus] 9.15 mL[middle dot]kg[superscript -1][middle dot]min[superscript -1], and menstrual…

Malek, Lukasz A.; Mróz, Anna; Czajkowska, Anna; Kosmol, Andrzej; Ogonowska-Slodownik, Anna; Molik, Bartosz; Morgulec-Adamowicz, Natalia – Research Quarterly for Exercise and Sport, 2019
Purpose: The aim of the study was to analyze the accuracy of impedance cardiography (ICG) for hemodynamic assessment in wheelchair rugby players during rest and exercise. Method: The study included 21 players (mean age 33.0 ± 5.4, 86% male) with posttraumatic tetraplegia. ECG, echocardiography, and gas exchange analysis during rest and exercise…
