The purpose of the study was to remove the influence of an external load and determine if muscle growth can be elicited by maximally contracting through a full range of motion. In addition, the acute physiologic and perceptual responses to each stimulus were also investigated. Thirteen participants completed 18 sessions of unilateral elbow flexion exercise.(More)
Blood flow restriction (BFR) training has been shown to increase muscle size and strength when combined with low-load [20-30 % one-repetition maximum (1RM)] resistance training in the lower body. Fewer studies have examined low-load BFR training in combination with upper body exercise, which may differ as some musculature cannot be directly restricted by(More)
Applying blood flow restriction during low-load resistance training has been shown to augment muscle hypertrophy which has been attributed to metabolic accumulation. It remains unknown, however, whether metabolites can augment muscle growth when maintained post-exercise. Thirteen untrained individuals (6 males and 7 females) performed 24 training sessions.(More)
In this paper we revisit a topic originally discussed in 1955, namely the lack of direct evidence that muscle hypertrophy from exercise plays an important role in increasing strength. To this day, long-term adaptations in strength are thought to be primarily contingent on changes in muscle size. Given this assumption, there has been considerable attention(More)
Muscle strength is often measured through the performance of a one-repetition maximum (1RM). However, we that feel a true measurement of 'strength' remains elusive. For example, low-load alternatives to traditional resistance training result in muscle hypertrophic changes similar to those resulting from traditional high-load resistance training, with less(More)
explained 18.7% of the variance in muscle strength. Our paper discusses the variety of correlations that are observed throughout the literature (as little as 2% to as great as 22%). Yet, despite these statistical relationships, we would remiss to suggest that these two phenomena are causally related just because they occur at the same time. For these two to(More)
The principle of progressive overload must be adhered to for individuals to continually increase muscle size with resistance training. While the majority of trained individuals adhere to this principle by increasing the number of sets performed per exercise session, this does not appear to be an effective method for increasing muscle size once a given(More)
Studies examining resistance training are of importance given that increasing or maintaining muscle mass aids in the prevention or attenuation of chronic disease. Within the literature, it is common practice to administer a set number of target repetitions to be completed by all individuals (i.e. 3 sets of 10) while setting the load relative to each(More)
OBJECTIVES Studies comparing multiple groups (i.e., experimental and control) often examine the efficacy of an intervention by calculating within group effect sizes using Cohen's d. This method is inappropriate and largely impacted by the pre-test variability as opposed to the variability in the intervention itself. Furthermore, the percentage change is(More)
The purpose of this study was to determine acute physiological and perceptual responses to two commonly implemented blood flow restriction protocols. Using a within-subject design, 15 participants (age ∼25) performed four sets of unilateral elbow flexion with each arm. One arm exercised using a 3-cm elastic cuff inflated to 160 mmHg, whereas the other arm(More)
