The Acute Impacts Of Resistance Training Performed With And Without Blood Flow Restriction On Lower Body Muscular Power, Justin Faller, Brian Thompson, Stephen Ives
The Acute Impacts Of Resistance Training Performed With And Without Blood Flow Restriction On Lower Body Muscular Power, Justin Faller, Brian Thompson, Stephen Ives
International Journal of Exercise Science
International Journal of Exercise Science 16(6): 1320-1333, 2023. The American College of Sports Medicine recommends resistance training using at least 70% one repetition maximum to improve muscular strength and hypertrophy; however, these intensities may not be safe for all populations. A training technique that has been reported to elicit increases in strength and muscle size uses low intensity resistance training or low load training in combination with blood flow restriction (BFR) to the working muscle. Although the acute effects of BFR on muscle strength and size are well established, the effects of BFR on muscular power are not definitively known. …

The Validity & Reliability Of The Repetitions In Reserve Based Rating Of Perceived Exertion Scale In Single Joint Exercise, Grant Malone
The Validity & Reliability Of The Repetitions In Reserve Based Rating Of Perceived Exertion Scale In Single Joint Exercise, Grant Malone
Masters Theses & Specialist Projects
Introduction: Intentional regulation and individualization of resistance training schemes are imperative when structuring a resistance training program. Optimal adaptation cannot be expected without proper manipulation of training variables such as load and volume. Load is traditionally prescribed by testing a given exercise’s repetition maximum and basing intensity from that load. This method of intensity regulation may be limited, considering it fails to recognize the day-to-day undulation of individual performance which can be impacted by several variables. A flexible method of regulating load and volume would be of use for those undergoing a resistance training program. The repetitions in reserve-based rating …
The Validity Of Perceptual Recovery Status On Monitoring Recovery During A High-Intensity Back Squat Session, Nicholas Buoncristiani
The Validity Of Perceptual Recovery Status On Monitoring Recovery During A High-Intensity Back Squat Session, Nicholas Buoncristiani
Masters Theses & Specialist Projects
Adaptations to resistance training and subsequent performance can be undermined by inadequate inter-set recovery. This time between sets is often uniformly prescribed based on desired training outcomes; however, there is demonstrative evidence that recovery is highly individualized. Methods typically used to monitor recovery were developed for longitudinal use, making them cost- or time -inefficient within a bout of exercise. If valid, the perceptual recovery status (PRS) scale may be used as an efficient and inexpensive recovery assessment tool to monitor individual recovery as well as appropriately modify rest periods. Purpose: The aim of the current study was to assess the …

Leg Lean Mass Adaptations Following Short-Term Barbell Training In Women, Jacob A. Mota, Matt S. Stock, Kendra D. Olinghouse, Alexander S. Drusch, Brennan J. Thompson
Leg Lean Mass Adaptations Following Short-Term Barbell Training In Women, Jacob A. Mota, Matt S. Stock, Kendra D. Olinghouse, Alexander S. Drusch, Brennan J. Thompson
International Journal of Exercise Science: Conference Proceedings
Participation in a resistance training program results in both neural adaptations and increases in lean body mass, the latter of which is considered a slow process. The majority of previous investigations that have examined the time course associated with muscular adaptations have utilized exercise machines or single-joint movements. Furthermore, the adaptations associated with resistance training in women are not as well understood as those for men. The purpose of this investigation was to examine the effects of a four week resistance training intervention on changes in leg lean mass in untrained, college-aged women. Thirty-five women (mean ± SD age = …
Comparison Of Multiple Sets And Single Set Of Resistance Training On Muscle Strength And Power, Junyoung Hong
Comparison Of Multiple Sets And Single Set Of Resistance Training On Muscle Strength And Power, Junyoung Hong
International Journal of Exercise Science: Conference Proceedings
Studies have been conducted to investigate the effects of different resistance training modalities on muscle strength and power in order to improve physical performance, yet to date findings have been inconclusive. Optimal resistance programs for muscular responses to high and low volume resistance training still need to be explored. The purpose of this study was to compare the effects of multiple sets (70% of 1RM, 3 sets/10 reps) and a single set (50-100% of 1RM, 1 set/up to 8 reps) of resistance training on muscular strength and power in healthy male college students. A total of 19 students were randomly …
