Endurance Tests Are The Most Reliable Core Stability Related Measurements, Andy Waldhelm, Li Li
Endurance Tests Are The Most Reliable Core Stability Related Measurements, Andy Waldhelm, Li Li
Li Li
Purpose: To determine the intra-tester reliability of clinical measurements that assess five components related to core stability: strength, endurance, flexibility, motor control, and function.
Methods: Participants were 15 college-aged males who had not suffered any orthopedic injury in the past year. Core strength measurements included eight isometric tests and a sit-up test. The four core endurance tests were the trunk flexor test, trunk extensor test, and bilateral side bridge tests. Flexibility tests included the sit-and-reach test and active range of the trunk and hip joint motions. Proprioception via passive reposition tests of the hips and a single limb balance test …

Few studies have compared anthropometric characteristics among national class athletes from different resistance training disciplines, such as Olympic Weightlifting (OL), Power Lifting (PL), and Bodybuilding (BB). Objective: The purpose of the current study was to determine if significant differences exist in the relationship between thigh muscle cross-sectional area and back squat strength among national class athletes from the sports of OL, PL, and BB. Methods: Fifteen national class athletes were assessed for back squat strength, mid-thigh circumference, and mid-thigh skinfold from which total thigh cross-sectional was estimated. A series of One-Way ANOVAs and Pearson Product Moment Correlations were used to …

Ground Reaction Forces Generated By Twenty-Eight Hatha Yoga Postures, Sylvia J. Wilcox, Ron Hager, Barbara Lockhart, Matthew K. Seeley
Ground Reaction Forces Generated By Twenty-Eight Hatha Yoga Postures, Sylvia J. Wilcox, Ron Hager, Barbara Lockhart, Matthew K. Seeley
International Journal of Exercise Science
Int J Exerc Sci 5(2) : 114-126, 2012. Adherents claim many benefits from the practice of yoga, including promotion of bone health and prevention of osteoporosis. However, no known studies have investigated whether yoga enhances bone mineral density. Furthermore, none have estimated reaction forces applied by yoga practitioners. The purpose of this study was to collect ground reaction force (GRF) data on a variety of hatha yoga postures that would commonly be practiced in fitness centers or private studios. Twelve female and eight male volunteers performed a sequence of 28 hatha yoga postures while GRF data were collected with an …
Acute Effects Of Antagonist Stretching On Jump Height, Torque, And Electromyography Of Agonist Musculature, John B. Sandberg, Dale R. Wagner, Jeffrey Willardson, Gerald Aparecido Smith
Acute Effects Of Antagonist Stretching On Jump Height, Torque, And Electromyography Of Agonist Musculature, John B. Sandberg, Dale R. Wagner, Jeffrey Willardson, Gerald Aparecido Smith
Faculty Research and Creative Activity
Although there has been substantial research on the acute effects of static stretching on subsequent force and power development, the outcome after stretching of the antagonist musculature has not been examined. The purpose of this study was to investigate the effects of static stretching of antagonist musculature on multiple strength and power measures. Sixteen trained men were tested for vertical jump height and isokinetic peak torque production during knee extension at 60°.s (SlowKE) and 300°.s (FastKE). Electromyography was recorded for the vastus lateralis and the biceps femoris muscles during isokinetic knee extension. Subjects performed these tests in a randomized counterbalanced …
