Assessment of Neuroplasticity With Strength Training

imageIncluding a brief overview of current investigative approaches, the present Perspectives for Progress article offers an overview of potential future experiments in the field of exercise-related neuroplasticity to strength training. It is proposed that the combination of specific experimental approaches and recently developed techniques holds the potential for unraveling spinal and supraspinal mechanisms involved in the adaptation to strength training.

Local Heat Therapy to Accelerate Recovery After Exercise-Induced Muscle Damage

imageThe prolonged impairment in muscle strength, power, and fatigue resistance after eccentric exercise has been ascribed to a plethora of mechanisms, including delayed muscle refueling and microvascular and mitochondrial dysfunction. This review explores the hypothesis that local heat therapy hastens functional recovery after strenuous eccentric exercise by facilitating glycogen resynthesis, reversing vascular derangements, augmenting mitochondrial function, and stimulating muscle protein synthesis.

Engineering Person-Specific Behavioral Interventions to Promote Physical Activity

imagePhysical activity is dynamic, complex, and often regulated idiosyncratically. In this article, we review how techniques used in control systems engineering are being applied to refine physical activity theory and interventions. We hypothesize that person-specific adaptive behavioral interventions grounded in system identification and model predictive control will lead to greater physical activity than more generic, conventional intervention approaches.

Myocellular Adaptations to Low-Load Blood Flow Restricted Resistance Training

imageLow-load blood flow restricted resistance exercise (BFRRE) can stimulate whole-muscle growth and improve muscle function. However, limited knowledge exists on the effects at the myocellular level. We hypothesize that BFRRE has the ability to produce concurrent skeletal muscle myofibrillar, mitochondrial, and microvascular adaptations, thus offering an alternative strategy to counteract decay in skeletal muscle health and function in clinical populations.

The Interplay Between Exercise Metabolism, Epigenetics, and Skeletal Muscle Remodeling

imageWe explore work from within the field of skeletal muscle and across the broader field of molecular biology, to propose that the link between exercise and skeletal muscle adaptation lies in the interplay between metabolism and epigenetics. Future investigations into such an interaction are crucial to advance our understanding of the beneficial effects of exercise on performance and health.

Consistent Morning Exercise May Be Beneficial for Individuals With Obesity

imageThis review explores the hypothesis that a consistent exercise time, especially consistent morning exercise, improves exercise adherence and weight management for individuals with overweight or obesity. We discuss data supporting this premise, identify limitations of current research, and outline directions for future research on exercise timing to more robustly evaluate our thesis.

On the Influence of Group III/IV Muscle Afferent Feedback on Endurance Exercise Performance

imageThis review discusses evidence suggesting that group III/IV muscle afferents affect locomotor performance by influencing neuromuscular fatigue. These neurons regulate the hemodynamic and ventilatory response to exercise and, thus, assure appropriate locomotor muscle O2 delivery, which optimizes peripheral fatigue development and facilitates endurance performance. In terms of central fatigue, group III/IV muscle afferents inhibit motoneuronal output and thereby limit exercise performance.
