International Journal of Exercise Science
International Journal of Exercise Science 15(7): 1538-1553, 2022. Higher wear compliance has been seen with wrist placed accelerometers versus hip placed. Performance of wrist placed ActiGraph GT3X+ accelerometer (GT3X+, ActiGraph LLC, Pensacola, FL) in assessing physical activity (PA) remains unclear. PURPOSE: This study examined GT3X+’s performance in measuring PA energy expenditure (PAEE) and classifying PA intensity in older women. METHODS: Women [n = 89, age = 65.6 (4.3)] wore GT3X+ and SenseWear Armband Mini (SWAM, BodyMedia Inc. Pittsburgh, PA) for 2 weeks. Concurrently, doubly labeled water (DLW) determined total daily energy expenditure (TDEE). Resting energy expenditure (REE) was determined …

International Journal of Exercise Science 15(4): 771-782, 2022. This study aimed to compare the effects of high-speed resistance training (HSRT) and low-speed resistance training (LSRT) in physical fitness, and functional performance in untrained older women. Twenty-four women (62.2 ± 2.7 years old) were allocated to the HSRT or LSRT groups. The HSRT and LSRT groups underwent a similar training program [3 sets of 8 to 12 repetitions at 90% of 10 maximum repetitions] for 14 weeks, twice a week. The LSRT group performed the exercises with 3 seconds in the concentric and eccentric phases, while the HSRT group performed with …

Participation In Higher Intensity Physical Activity Predicts Lower Depressive Symptom Incidence In College Students, Lucas D. Elliott, Oliver Wilson, Michele Duffey, Melissa Bopp
International Journal of Exercise Science
International Journal of Exercise Science 15(7): 667-675, 2022. The prevalence of depression and insufficient physical activity (PA) continue to rise in the United States, particularly among college students. PA is typically associated with decreased levels of depressive symptoms; however, the association between different intensities of PA and depressive symptoms is unclear among college students. The aim of this study was to examine how well weekly moderate PA (MPA), vigorous PA (VPA) and strength training (ST) volumes predicted depressive symptoms in college students. Students self-reported weekly MPA, VPA, ST, depressive symptoms (CESD-7), restful nights of sleep, grade point average (GPA) and …

International Journal of Exercise Science
International Journal of Exercise Science 15(6): 686-701, 2022. Montmorency Cherry Juice (MCJ) may improve acute exercise recovery by attenuating inflammation and oxidative stress. However, the anti-inflammatory effects of MCJ on monocyte responses following resistance exercise have not been explored. Seven resistance-trained males (age: 22.9 ± 4.1 yrs; height: 1.8 ± 0.1 m; weight: 81.7 ± 13.2 kg) participated in this study. Participants completed a placebo-controlled crossover design, drinking either MCJ or placebo beverages, 7 days prior to completing an acute bout of unilateral resistance exercise. Statistical significance was assessed using a within-subjects repeated measures ANOVA; alpha level p ≤ 0.05. …

Effects Of A Demand-Valve Scuba Regulator On Cardiorespiratory Response During Submaximal Exercise Under Normobaric Conditions: A Preliminary Investigation, Christopher R. Kovacs Ph.D., Camille Dhom B.S.
International Journal of Aquatic Research and Education
SCUBA diving fatalities are often related to cardiac events triggered by stress linked to equipment. The purpose of this investigation was to examine the effects of a SCUBA regulator on cardiorespiratory exercise at a submaximal workload. Ten participants (mean = 21.5 yrs; s.d. = 1.16) completed two submaximal exercise tests at 1 ATA; one while breathing normally and a second while breathing directly from a demand valve SCUBA regulator. Total time to test completion (TOT), heart rate (HR), blood pressure (BP), rating of perceived exertion (RPE), and arterial oxygen levels were all assessed. No significant differences between conditions were found …

International Journal of Exercise Science
International Journal of Exercise Science 15(3): 177-190, 2022. The purpose of this study was to evaluate the relationships between subjective, self-reported cancer related fatigue (CRF) and objective measures of muscular strength and fatigability in cancer survivors. A total of 155 cancer survivors (60 ± 13 years of age) completed a questionnaire for the assessment of CRF, along with assessments of handgrip strength, quadriceps strength and fatigability (reduced force/torque). Fatigability was measured by completing 15 maximal isokinetic contractions of the knee extensors (QFI). Spearman’s rho correlation coefficients were calculated as pairwise combinations of the numerical and categorical dependent measures. Categorical variables …
