Rainey-Smith, Jeremiah Peiffer, Hamid R. Sohrabi, James Doecke, Natalie J. Frost, Shaun J. Markovic, Kirk Erickson, Belinda M. Brown

Research outputs 2022 to 2026

Objectives: Observational studies consistently demonstrate that physical activity is associated with elevated cognitive function, however, there remains significant heterogeneity in cognitive outcomes from randomized exercise interventions. Individual variation in sleep behaviours may be a source of variability in the effectiveness of exercise-induced cognitive change, however this has not yet been investigated. The current study aimed to (1) investigate the influence of a 6-month exercise intervention on sleep, assessed pre- and post-intervention and, (2) investigate whether baseline sleep measures moderate exercise-induced cognitive changes. Methods: We utilised data from the Intense Physical Activity and Cognition (IPAC) study (n = 89), a 6-month …

Effects And Moderators Of Exercise Medicine On Cardiometabolic Outcomes In Men With Prostate Cancer Previously Or Currently Undergoing Androgen Deprivation Therapy: An Individual Patient Data Meta-Analysis, Pedro Lopez, Robert U. Newton, Dennis R. Taaffe, Kerri Winters-Stone, Laurien M. Buffart, Daniel A. Galvão

Research outputs 2022 to 2026

Purpose: To examine the effects and moderators of exercise effects on cardiometabolic outcomes in men with prostate cancer previously or currently undergoing androgen deprivation therapy (ADT). Results: Seven trials including 560 patients were examined. Exercise resulted in significant effects on whole-body and regional fat mass (P ≤ 0.001). For whole-body fat mass, significant exercise effects were observed in patients who were unmarried (−1.4 kg, P < 0.05) and who presented with higher fat mass levels (−1.0 kg, P < 0.05). For diastolic blood pressure and low-density lipoprotein (LDL), younger (−4.7 mmHg, P < 0.05) and older patients (−0.2 mmol.l-1, P < 0.10) achieved greater effects, respectively. Regarding high-density lipoprotein (HDL), patients undertaking ADT + prostatectomy + radiotherapy derived significant exercise effects (0.3 mmol.l-1, P < 0.05). Conclusions: Exercise effectively reduces fat mass across subgroups of men undergoing or following ADT with different characteristics. For diastolic blood pressure, HDL and LDL, groups based on age and treatment history could be specifically targeted with exercise medicine.

Moderate To Vigorous-Intensity Continuous Training Versus High-Intensity Interval Training For Improving Vo2max In Women: A Systematic Review And Meta-Analysis, Robert Lindner, Isaac Selva Raj, Angela W. H. Yang, Shadman Zaman, Brianna Larsen, Joshua Denham

Research outputs 2022 to 2026

Traditional continuous training and high-intensity interval training (HIIT) can increase maximal oxygen uptake (VO2max). However, there is conflicting evidence regarding which form of training demonstrates the greatest improvements to VO2max, and data in women is sparse. We conducted a systematic review and meta-analyses to assess whether moderate to vigorous-intensity continuous training (MVICT) or HIIT was superior at improving VO2max in women. Randomised controlled and parallel studies examined the influence of MVICT and/or HIIT on VO2max in women. There was no statistical difference in VO2max improvements after training between women in the MVICT and HIIT cohorts (mean difference [MD]: −0.42, 95%CI: …

Research outputs 2022 to 2026

Purpose:

Vitamin D supplementation may have non-skeletal health benefits and enhance exercise responsiveness, particularly in those with low vitamin D levels. We determined whether, compared with placebo, vitamin D supplementation taken prior to and during a 12-week exercise program improves physical function, body composition or metabolic health, in overweight and obese older adults with vitamin D deficiency.

Methods:

Fifty overweight or obese older adults (mean ± SD age: 60 ± 6 years; BMI 30.6 ± 5.7 kg/m2) with vitamin D deficiency (25-hydroxyvitamin D [25(OH)D] < 50 nmol/L) were recruited. Participants were randomly allocated to receive either vitamin D3 (4000 IU/day) or matching placebo for 24 weeks. Between weeks 12 and 24, all participants completed multi-modal exercise three days per week while continuing with vitamin D/placebo. Mean changes in physical function (primary outcome: gait speed), body composition and biochemical parameters at weeks 12 and 24 were compared between groups.

Results:

Vitamin D supplementation, with or without exercise, had no effect on gait speed. From baseline …

Exercise Builds The Scaffold Of Life: Muscle Extracellular Matrix Biomarker Responses To Physical Activity, Inactivity, And Aging, Georgios Mavropalias, Marni Boppart, Kayley M. Usher, Miranda D. Grounds, Kazunori Nosaka, Anthony J. Blazevich

Research outputs 2022 to 2026

Skeletal muscle extracellular matrix (ECM) is critical for muscle force production and the regulation of important physiological processes during growth, regeneration, and remodelling. ECM remodelling is a tightly orchestrated process, sensitive to multi-directional tensile and compressive stresses and damaging stimuli, and its assessment can convey important information on rehabilitation effectiveness, injury, and disease. Despite its profound importance, ECM biomarkers are underused in studies examining the effects of exercise, disuse, or aging on muscle function, growth, and structure. This review examines patterns of short- and long-term changes in the synthesis and concentrations of ECM markers in biofluids and tissues, which may …

Maximal Number Of Repetitions At Percentages Of The One Repetition Maximum: A Meta-Regression And Moderator Analysis Of Sex, Age, Training Status, And Exercise, James L. Nuzzo, Matheus D. Pinto, Kazunori Nosaka, James Steele

Research outputs 2022 to 2026

The maximal number of repetitions that can be completed at various percentages of the one repetition maximum (1RM) [REPS ~ %1RM relationship] is foundational knowledge in resistance exercise programming. The current REPS ~ %1RM relationship is based on few studies and has not incorporated uncertainty into estimations or accounted for between-individuals variation. Therefore, we conducted a meta-regression to estimate the mean and between-individuals standard deviation of the number of repetitions that can be completed at various percentages of 1RM. We also explored if the REPS ~ %1RM relationship is moderated by sex, age, training status, and/or exercise. A total of …
