The Relationship Between Physical Characteristics and Maximal Strength in Men Practicing the Back Squat, the Bench Press and the Deadlift

International Journal of Exercise Science 13(4): 281-297, 2020. This study was designed to quantify the relationships between physical characteristics and maximal strength in the back squat, the bench press and the deadlift on powerlifters and football players.Eighteen male junior drug-tested classic powerlifters and seventeen NCAA Division II American football players’ anthropometric measurements were taken to compare them with maximal strength results from either a powerlifting meet or testing from their supervised strength and conditioning program. Pearson’s bivariate correlations analysis revealed (statistical significance was set at

The Acute Effect of Walking on Ultrasound Measurements from the Achilles InSight Ultrasonometer in College-aged Individuals

International Journal of Exercise Science 9(4): 491-496, 2016. The Achilles InSight bone ultrasonometer is a portable ultrasound device for quantitatively measuring bone composition both safely and inexpensively via the calcaneus. The effect of acute, brisk walking as a possible source of error on the reliability of quantitative ultrasound (QUS) measurements was investigated. Forty-seven participants (17 women, 30 men; age M ± SD = 20.44 ± 1.16) had their calcaneus measured with the Achilles InSight both before and after a 15-min bout of walking at (5.63 km·h-1 (3.5 mph). The Achilles InSight was deemed reliable via a test-and-retest protocol (ICC α = 0.94). The reliability of the Achilles InSight indicated that the measurement was statistically unaffected by the effects of acute, brisk walking

Kinesio Tape® Applied to the Thorax Augments Ventilatory Efficiency during Heavy Exercise

International Journal of Exercise Science 6(2) : 157-163, 2013. Kinesio Tape® (KT) is purported to help coordinate involuntary contractions. KT applied to the thorax is believed to enhance breathing during constant-load exercise, but verification is lacking. We had 12 participants complete a graded exercise test to determine gas-exchange threshold (GET), and two, constant-load bouts sufficient in intensity to evoke the VO2 slow component using no tape (NT) or KT applied to the thorax, respectively, in counterbalanced order. Indirect calorimetery measured ventilatory and gas-exchange parameters, and a 3-lead EKG recorded heart rate (HR). A greater expiratory tidal volume (+150 mL·min-1) along with a small, yet significant (P \u3c 0.05), improvement in mechanical efficiency occurred when using KT. Using KT did not affect exercising respiratory rate or HR, and most participants reported that KT was comfortable during exercise. ATs may apply KT to the thorax to improve heavy exercise efficiency, but research on exhaustive exercise is warranted
