Feasibility And Acceptability Of A Remotely Delivered, Home-Based, Pragmatic Resistance ‘Exercise Snacking’ Intervention In Community-Dwelling Older Adults: A Pilot Randomised Controlled Trial, Jackson J. Fyfe, Jack Dalla Via, Paul Jansons, David Scott, Robin M. Daly

Research outputs 2022 to 2026

Background: Very few older adults meet current muscle strengthening exercise guidelines, and several barriers exist to supervised, community-based resistance exercise programs. Older adults therefore require access to feasible resistance exercise modalities that may be performed remotely. This pilot study assessed the feasibility and acceptability of undertaking a four-week home-based resistance ‘exercise snacking’ intervention (performed either once, twice, or thrice daily) when delivered and monitored remotely in older adults. Methods: Thirty-eight community-dwelling older adults [mean ± SD age 69.8 ± 3.8 y, 63% female] were randomised to complete resistance ‘exercise snacks’ (9-minute sessions) either once (n = 9), twice (n = …

Study Protocol: Investigating The Feasibility Of A Hybrid Delivery Of Home-Based Cluster Set Resistance Training For Individuals Previously Treated For Lung Cancer, C. M. Fairman, O. L. Owens, Kristina L. Kendall, J. Steele, Christopher Latella, M. T. Jones, L. Marcotte, Carolyn M. J. Peddle-Mcintyre, K. K. Mcdonnell

Research outputs 2022 to 2026

Background: Symptom burden remains a critical concern for individuals with non-small cell lung cancer (NSCLC) following the completion of treatment. The most common symptom clusters, dyspnea (shortness of breath) and fatigue, can contribute to physical decline, reductions in quality of life, and a higher risk of comorbidities and mortality. Dyspnea is a primary limiter of exercise capacity in individuals with lung cancer, resulting in exercise avoidance and an accelerated physical decline. As such, designing resistance training with cluster sets to mitigate symptoms of dyspnea and fatigue may result in improved exercise tolerance. Thus, maintaining the exercise stimulus via cluster sets, …

Different Resistance Training Protocols During The Crunch Exercise Affect Muscle Thickness, Echo-Intensity, Load Lifted, And Perception Of Effort In Recreationally-Trained Participants., Keanna J. Sullivan, Paulo H. Marchetti

International Journal of Exercise Science: Conference Proceedings

The correct choice of the acute variables is another important component of a resistance training (RT) session. The combination of intensity and volume is fundamental to determine the dose-response in a RT session and can induce specific metabolic and mechanical stress in the muscle. PURPOSE: The primary purpose of this study was to evaluate acute dose-response of different volume x intensity RT protocols with equated total volume (40 repetitions) during the crunch exercise on muscle thickness, echo-intensity, load lifted, and rating of perceived exertion in recreationally-trained participants. METHODS: Fifteen resistance-trained participants (23±3years, 76.4±6.5kg, 173.3±6.5cm) performed the abdominal crunch exercise …

Creatine Supplementation Improves Performance Without Deleterious Cardiovascular Parameters In Trained Females, Citlaly Jauregui, Steven B. Machek, Katia Azevedo, Warleyson Azevedo, Jeffrey Willardson, Marco Machado

International Journal of Exercise Science: Conference Proceedings

Creatine monohydrate supplementation is broadly substantiated to elicit both favorable ergogenic and health-associated advantages amidst vast demographics. Nevertheless, its impacts on human cardiovascular outcomes are hitherto undescribed in generally healthy populations. Furthermore, females are largely underrepresented in the ergogenic creatine literature and their potentially differential cardiovascular responses are unknown. PURPOSE: to determine whether young, healthy females would glean discernible hypertrophy and enhanced performance, commensurate to favorable post-resistance training cardiovascular parameters and relative to placebo-matched controls across a four week training timeline. METHODS: Twenty-eight resistance trained women (25.5±6.1 years) were randomly assigned to supplement creatine monohydrate (CRE; 5g creatine monohydrate …

The Effects Of Acute Beetroot Juice Ingestion On Upper And Lower Body Muscular Power During Weightlifting Exercise In Men., Sean Karl, Isabella Lincoln, Joanna Powell, Grant Weiderman, Katie Price, Lauren Wideen, Andrew Fest, Justin Kim, Maya Hammer, Noelle Seekamp-Hicks, Joshua Leow, Maddy Espinoza, Adam Pennell, Rachel Tan

Seaver College Research And Scholarly Achievement Symposium

Dietary nitrate supplementation, administered per beetroot juice (BR), has been shown to enhance performance while cycling and running. BR has enhanced skeletal muscle contraction and blood flow within type II fibers which are recruited during high-velocity and high-power contractions. However, it is unknown whether BR influences alternative forms of exercise, such as resistance exercise. The purpose of this study is to assess whether BR supplementation influences neuromuscular performance (muscle power and speed), and repetitions-to-failure in healthy, recreationally active men. In a double-blind, randomized crossover design, 14 males will be recruited to complete two 4-day supplementation periods in which they consume …

Comparison Of Weightlifting, Traditional Resistance Training And Plyometrics On Strength, Power And Speed: A Systematic Review With Meta-Analysis, Stephanie J. Morris, Jon L. Oliver, Jason S. Pedley, G. Gregory Haff, Rhodri S. Lloyd

Research outputs 2022 to 2026

Background:

Weightlifting training (WLT) is commonly used to improve strength, power and speed in athletes. However, to date, WLT studies have either not compared training effects against those of other training methods, or been limited by small sample sizes, which are issues that can be resolved by pooling studies in a meta-analysis. Therefore, the objective of this systematic review with meta-analysis was to evaluate the effects of WLT compared with traditional resistance training (TRT), plyometric training (PLYO) and/or control (CON) on strength, power and speed.

Methods:

The systematic review included peer-reviewed articles that employed a WLT intervention, a comparison group …
