Early Timeline Of Lean Tissue Mass And Strength Improvements In Trained Men Following A High Volume/Frequency Resistance Training Program, Michael H. Thomas, Robert H. Ferguson, Steve P. Burns, Natalie B. Allen
International Journal of Exercise Science
International Journal of Exercise Science 12(4): 1094-1109, 2019. The purpose of this study was to determine the early timeline effect of a systemic high volume/frequency resistance training intervention on lean tissue mass and strength in trained men. Twenty-two healthy resistance trained men, age (32.29 ± 9.75 years), training age (9.40 ± 6.18 years) were placed on a 4-week resistance training (RT) intervention with lean mass and strength assessed pre, mid, and post intervention. RT consisted of 6 exercises: flat smith chest press, pull ups, triceps pushdowns, dumbbell bicep curls, leg press or walking lunges, and standing calf raises, completing 5 …
Exercise Is Medicine®: Knowledge And Awareness Among Exercise Science And Medical School Students, Rachel Mealy, Laura Richardson, Brian Miller, Melissa Smith, Judith A. Juvancic-Heltzel
Exercise Is Medicine®: Knowledge And Awareness Among Exercise Science And Medical School Students, Rachel Mealy, Laura Richardson, Brian Miller, Melissa Smith, Judith A. Juvancic-Heltzel
International Journal of Exercise Science
International Journal of Exercise Science 12(3): 505-514, 2019. The purpose of this exploratory study was twofold: to determine whether exercise science and medical students are aware of the Exercise is Medicine® (EIM®) program and to construct a tool that would permit assessment of EIM® variables with students enrolled in both programs. The study consisted of a quantitative, cross-sectional design, using a self-report electronic questionnaire. An Exploratory Factor Analysis (EFA) using principal component analysis extraction method with Varimax factor rotation was employed to validate the survey instrument based on the expected constructs, which posited five (5) contending …

Development Of The Physical Activity Tracking Preference Questionnaire, Emily Fu, Marney A. White, Jaclyn M. W. Hughto, Bella Steiner, Erik Willis
International Journal of Exercise Science
International Journal of Exercise Science 12(5): 297-309, 2019. The present study aims to develop the Physical Activity Tracking Preference Questionnaire (PATPQ), a measure of unit (distance, steps, calories, minutes) preference for tracking physical activity. The PATPQ was developed in two phases. During Phase One, the initial PATPQ was created (24 items), was assessed by an expert panel for face validity, and tested in 557 adults. Results were used to revise and modify the PATPQ. In Phase Two, the item pool was expanded and tested in 374 adults. Kuder‐Richardson Formula 20 scores for internal consistency and interclass correlations for test-retest reliability …
Maximal Lactate Steady State And Lactate Thresholds In The Cross-Country Skiing Sub-Technique Double Poling, Johan Jakobsson, Christer Malm
Maximal Lactate Steady State And Lactate Thresholds In The Cross-Country Skiing Sub-Technique Double Poling, Johan Jakobsson, Christer Malm
International Journal of Exercise Science
International Journal of Exercise Science 12(2): 57-68, 2019. The response of blood lactate concentration (BLC) to exercise is a commonly used approach to set training intensities and to determine the anaerobic threshold, which are important in evaluation of endurance exercise performance. The maximal lactate steady state (MLSS) is defined as the highest workload or BLC that can be maintained without continual lactate accumulation over time. The aim of this study was to investigate MLSS in the cross-country skiing sub-technique double poling and to assess the validity of a fixed blood lactate threshold (OBLAand the 45° tangent of the lactate curve). …
