#1
Ryan E Rhodes, Amanda Rebar
Intention has been an extremely important concept in physical activity theory and research but is complicated by a double-barreled definition of a decision to perform physical activity and/or the commitment to enact that decision. We put forth the hypothesis that these separate meanings have different measurement requirements, are situated in distinctly different intention-based models, and show discrete findings when explaining physical activity motives.

Dopaminergic signaling differences in the nucleus accumbens (NAcc) seemingly predispose rats to adopt different physical activity behaviors. Physical activity behavior may also be regulated through peripheral mechanisms (i.e., muscle and fat-derived as well as hormonal signals). We hypothesize that physical activity behavior is regulated by the convergence of central and peripheral mechanisms onto the nucleus accumbens.

Erik P Rader, Brent A Baker
With aging, muscle injury from rapid, continuous stretch-shortening contractions (SSCs) is prolonged and maladaptation to moderate-velocity, intermittent SSCs is more common. We investigate the hypothesis that high baseline levels of inflammatory signaling and oxidative stress may underlie these outcomes, while careful modulation of high-intensity SSC training design resets basal conditions and permits muscle adaptation to SSCs.

#6
David E Conroy, Tanya R Berry
People do not appear to be willing or able to sustain effortful self-regulation for behaviors, such as physical activity. Affective processes can account for why some behaviors are more intrinsically rewarding than others. In this paper, we hypothesize that automatic affective evaluations are instrumental to the regulation of physical activity in everyday life.

#7
Jaap H van Dieën, Herta Flor, Paul W Hodges
We hypothesize that changes in motor behavior in individuals with low-back pain are adaptations aimed at minimizing the real or perceived risk of further pain. Through reinforcement learning, pain and subsequent adaptions result in less dynamic motor behavior, leading to increased loading and impoverished sensory feedback, which contributes to cortical reorganization and proprioceptive impairments that reduce the ability to control lumbar movement in a robust manner.

Considerable variability exists in the cardiometabolic disease biomarker response to exercise. We propose that a major contributor to this heterogeneity is underpowered studies due to small sample sizes. To test our hypothesis, we conducted a systematic review to identify meta-analyses/reviews of randomized controlled trials (RCT) and RCT that examined the cardiometabolic disease biomarker response to aerobic and resistance exercise.

#13
Nicholas A Burd, Michael De Lisio
Nutrition and exercise are important components of a healthy lifestyle to improve rates of hypertrophic and nonhypertrophic skeletal muscle remodeling. We provide evidence to support the hypothesis that muscle stem cells and protein turnover are collaborative, not separate, mechanisms supporting muscle remodeling by facilitating protein, nuclear, and cellular turnover in response to the ingestion of protein dense foods and exercise.

#14
Steven J Trangmar, José González-Alonso
Exercise-induced dehydration can lead to impaired perfusion to multiple regional tissues and organs. We propose that the impact of dehydration on regional blood flow and metabolism is dependent on the extent of the cardiovascular demand imposed by exercise, with the greatest physiological strain seen when approaching cardiovascular and aerobic capacities.

Hepatic steatosis prevails each year. Autophagy is integral in mitochondrial quality control and lipid homeostasis in the liver. No pharmacological strategies are currently available to reduce hepatic steatosis, but exercise has been known to improve clinical outcomes of chronic liver disease, particularly nonalcoholic fatty liver disease (NAFLD). Recent studies suggest that exercise may improve NAFLD through enhancing autophagy.

Shizue Masuki, Mayuko Morikawa, Hiroshi Nose
No long-term exercise training regimen with high adherence and effectiveness for middle-aged and older individuals is currently broadly available in the field. To address this problem, we developed an exercise training system comprising interval walking training and an information technology network that requires only minimal staff support. We hypothesized that our training system could increase physical fitness in older people.

Work-related physical activity (PA), in terms of peak loads and sustained and/or repetitive contractions, presents risk factors for the development of muscular pain and disorders. However, PA as a training tailored to the employee's work exposure, health, and physical capacity offers prevention and rehabilitation. We suggest the concept of "Intelligent Physical Exercise Training" relying on evidence-based sports science training principles.

Exercise frequently is prescribed therapeutically, either on its own or combined with drugs. A drug's absorption, distribution, metabolism, and excretion can be affected by the user's anatomy and physiology, which are both changed by the myriad of complex adaptations to acute and chronic exercise. This article reviews the research that suggests exercise may influence a drug's plasma concentration, and thus its efficacy and safety.

Hematopoietic stem cell (HSC) transplantation and adoptive transfer immunotherapy are effective in treating blood cancers and posttransplant infections, but low-circulating cell numbers in patients and donors are oftentimes a limiting factor. We postulate that a single exercise bout will increase the yield of patient- and donor-derived HSCs and cytotoxic lymphocytes to improve this form of treatment for cancer patients.
