A Systematic Review Of The Effects Of Meditative And Mindful Walking On Mental And Cardiovascular Health, Dustin W. Davis, Bryson Carrier, Kyle Cruz, Brenna Barrios, Merrill Russen Landers, James W. Navalta
International Journal of Exercise Science
International Journal of Exercise Science 15(2): 1692-1734, 2022. Meditative and mindful exercise are types of physical exercise during which people pay attention, on purpose, to each new present moment without judging their experience. The goal is to apply an accepting awareness of the environment, bodily sensations, thoughts, and emotions without labeling them (e.g., good or bad). The literature centers on qigong, tai chi, and yoga, which are types of mindful exercise that improve mental and cardiovascular health. It is unclear if meditative and mindful walking also improve these health domains. To the authors’ knowledge, this question has not been addressed …

Differences In Rate Of Perceived Exertion And Workload Intensity In Males And Females During Submaximal Arm And Leg Ergometry, Konrad J. Dias, Amanda Mungenast, Stephanie Sherwood, Patrick Mcpherson, Allison Verville, Shannon Eaton, Dustin Nadler
International Journal of Exercise Science
International Journal of Exercise Science 15(4): 1222-1235, 2022. Purpose: Arm ergometry (AE) is necessitated for individuals unable to perform leg ergometry (LE) exercise. This study explored gender differences in RPE and workload (WL) during AE and LE at submaximal target heart rates (THR). Methods: 35 healthy college-aged individuals were randomly allocated to begin exercise on either AE or LE. Participants exercised on both modes with increasing WL to achieve submaximal THRs of 110, 120, 130, 140 and 150 beats per minute (bpm). Factorial ANOVAs tested for differences in RPE and WL. Results: No significant differences were found in RPE between …

Sex Differences In Measures Of Wave Reflection And Aortic Arterial Stiffness In Response To Weight Machine Resistance Exercise, Emily K. Erb, Stacie Humm, Sarah Kearney, Anthony G. Pinzone, Michelle A. Kern, J. Derek Kingsley
International Journal of Exercise Science
International Journal of Exercise Science 15(2): 1190-1201, 2022. While it has been demonstrated that acute resistance exercise (RE) alters measures of wave reflection and aortic arterial stiffness in young, healthy individuals, limited research has evaluated sex differences. Accordingly, we recruited moderately active, resistance-trained men (Age: 22 ± 3yrs, n=12) and women (23 ± 3yrs, n=10) to perform two randomized conditions consisting of an acute bout of weight machine RE or a quiet control (CON). Measures of aortic wave reflection and aortic stiffness were taken at baseline and 15 minutes following the RE (Recovery). At baseline, women had significantly higher heart …

Impact Of Acute Uninterrupted Sitting On Cerebrovascular Hemodynamics, Raymond Jones, Dominique Mcarthur, Stephanie Mccoy, Lee Stoner, Simon Fryer, Daniel P. Credeur
International Journal of Exercise Science
International Journal of Exercise Science 15(2): 1156-1167, 2022. Reductions in brain blood flow are associated with reduced cognitive function and cerebrovascular disease. Acute periods of uninterrupted sitting can lead to endothelial dysfunction, namely due to a reduction in shear stress and subsequent reduction in nitric oxide bioavailability. Little is known of the impact of sitting on brain health. The purpose was to determine the total brain blood flow response following a 60-minute bout of uninterrupted sitting. Using a parallel design, this study evaluated the impact of 60-minutes of sitting on total brain blood flow. Fifteen participants (n=15; age=24 ± …
Aerobic Performance Detriments While Wearing A Face Mask Diverge Among Males And Females, Jose M. Moris, Yunsuk Koh
Aerobic Performance Detriments While Wearing A Face Mask Diverge Among Males And Females, Jose M. Moris, Yunsuk Koh
International Journal of Exercise Science
International Journal of Exercise Science 15(2): 1105-1116, 2022. The current study examined the impact of wearing a face mask (FM) at rest and while exercising on cardiorespiratory variables and aerobic performance between males and females. Nine males (21.4 ± 0.5 yr) and 9 females (21.8 ± 3.6 yr) performed a pulmonary function test and a graded maximal exercise test (GXT) on a treadmill with an FM and without an FM in random order. During the GXT, cardiorespiratory variables were measured at different exercise intensities (rest, 40%, 55%, 70%, 80%, 100% of VO2max) and during recovery. Regardless of sex, …
Post-Exercise Arterial Stiffness Responses Are Similar After Acute Eccentric And Concentric Arm Cycling, Travis R. Wakeham, Dakota J. Anderson, Steven J. Elmer, John J. Durocher
Post-Exercise Arterial Stiffness Responses Are Similar After Acute Eccentric And Concentric Arm Cycling, Travis R. Wakeham, Dakota J. Anderson, Steven J. Elmer, John J. Durocher
International Journal of Exercise Science
International Journal of Exercise Science 15(2): 884-895, 2022. Upper-body resistance exercise effectively increases muscular strength, but may concomitantly increase arterial stiffness. Eccentric exercise can lead to muscle soreness and arterial stiffness in untrained participants. However, it is unclear if upper-body eccentric exercise could reduce arterial stiffness in a single session for participants that have undergone progressive training. Our purpose was to compare acute responses to upper-body eccentric (novel, ECCarm) and concentric (traditional, CONarm) steady state arm cycling. We hypothesized that arm arterial stiffness would be reduced after both ECCarm and CONarm. Twenty-two young healthy individuals performed either ECCarm (n …

Acute Hemodynamic Response To Intradialytic Blood Flow Restriction Training, Rony Nobre, Rodrigo Cardoso, Aline Araujo, Rafael Orcy, Jeniffer Aquino, Larissa Ribeiro, Rafaela Catto, Ana Carolina Conteratto, Airton Rombaldi, Maristela Bohlke
Is It Safe For Hemodialysis Patients To Seek Gains With Less Pain? Acute Hemodynamic Response To Intradialytic Blood Flow Restriction Training, Rony Nobre, Rodrigo Cardoso, Aline Araujo, Rafael Orcy, Jeniffer Aquino, Larissa Ribeiro, Rafaela Catto, Ana Carolina Conteratto, Airton Rombaldi, Maristela Bohlke
International Journal of Exercise Science
International Journal of Exercise Science 15(2): 434-441, 2022. Considering that the hemodynamic safety is a major concern about intradialytic exercise with blood flow restriction, this analysis was performed to compare the blood pressure (BP) behavior during the first two hours of hemodialysis (HD) between sessions with no exercise (control group, CG), low/moderate intensity aerobic exercise with blood flow restriction (BFRE) and conventional aerobic exercise (AE). Adult patients with chronic kidney disease on HD at a university hospital were randomly assigned and submitted to a 12-week intradialytic training with BFRE or AE compared with the CG group. The main outcomes of …
Behavior Change Trajectories And Metabolic Syndrome Risk Factor Clustering During The Transition To College: A Feasibility Pilot Study, Alexandra N. Smith, Lauren Q. Higgins, Simon Higgins
Behavior Change Trajectories And Metabolic Syndrome Risk Factor Clustering During The Transition To College: A Feasibility Pilot Study, Alexandra N. Smith, Lauren Q. Higgins, Simon Higgins
International Journal of Exercise Science
International Journal of Exercise Science 15(5): 125-141, 2022. Metabolic syndrome (MetS) is typically diagnosed in adults; however, MetS risk factors are growing in prevalence during youth and young adulthood. Though the transition from high school to college is associated with adverse changes in lifestyle behaviors that may contribute to MetS risk factor development, the relationship between pre-college MetS risk status and transition-related behavior change is unknown. This prospective study aimed to describe the relationship between pre-college MetS risk status and transition-related behavior change trajectories in college-bound students. Moreover, it aimed to assess the feasibility of the study design, including acceptability …
