The Effects of Boxing Glove Design on Thumb Position When Making a Fist for Striking.

Peveler, WW, Schoffstall, J, Coots, J, Kilian, J, and Glauser, J. The effects of boxing glove design on thumb position when making a fist for striking. J Strength Cond Res 38(5): 948-950, 2024-It has been suggested that boxing glove design alters thumb position increasing the risk of injury.

Comparison of Ventilatory Measures and 20 km Time Trial Performance.

Performance threshold measures are used to predict cycling performance. Previous research has focused on long time trials (≥ 40 km) using power at ventilatory threshold and respiratory threshold to estimate time trial performance. As intensity greatly differs during shorter time trails applying findings from longer time trials may not be appropriate.

Effects of Energy Drinks on Economy and Cardiovascular Measures.

Peveler, WW, Sanders, GJ, Marczinski, CA, and Holmer, B. Effects of energy drinks on economy and cardiovascular measures. J Strength Cond Res 31(4): 882-887, 2017-The use of energy drinks among athletes has risen greatly.

The accuracy of simulated indoor time trials utilizing a CompuTrainer and GPS data.

The CompuTrainer is commonly used to measure cycling time trial performance in a laboratory setting. Previous research has demonstrated that the CompuTrainer tends toward underestimating power at higher workloads but provides reliable measures. The extent to which the CompuTrainer is capable of simulating outdoor time trials in a laboratory setting has yet to be examined.

Effect of magnesium lactate dihydrate and calcium lactate monohydrate on 20-km cycling time trial performance.

Manufacturers of supplements containing magnesium lactate dihydrate and calcium lactate monohydrate claim improved athletic performance. Although energy can be produced through the lactate shuttle system, there is limited evidence to suggest that substantial quantities are available for human movement during exercise. The purpose of this study was to evaluate the effectiveness of lactate as a performance-enhancing substance.

A kinematic comparison of alterations to knee and ankle angles from resting measures to active pedaling during a graded exercise protocol.

Saddle height is one of the most researched areas of bike fit. The current accepted method for adjusting saddle height involves the use of a goniometer to adjust saddle height so that a knee angle between 25° and 35° is obtained. This measurement is taken while the cyclist maintains a static position with the pedal at the 6-o'-clock position.

Effects of saddle height on economy and anaerobic power in well-trained cyclists.

In cycling, saddle height adjustment is critical for optimal performance and injury prevention. A 25-35° knee angle is recommended for injury prevention, whereas 109% of inseam, measured from floor to ischium, is recommended for optimal performance. Previous research has demonstrated that these 2 methods produce significantly different saddle heights and may influence cycling performance.

Effects of ribose as an ergogenic aid.

The amount of adenosine triphosphate (ATP) stored in the muscle available for immediate use is limited, and once used, must be resynthesized in the muscle. Ribose, a naturally occurring pentose sugar, helps resynthesize ATP for use in muscles. There have been claims that ribose supplements increase ATP levels and improve performance.

A comparison of respiratory compensation thresholds of anaerobic competitors, aerobic competitors and untrained subjects.

This study compared respiratory compensation thresholds (RCT) ( VCO(2) inflection point) of competitors in highly aerobic events (aerobic competitors, ARC) ( n=16), competitors in highly anaerobic events (anaerobic competitors, ANC) ( n=15), and untrained subjects (UT) ( n=25). Maximal oxygen consumption ( VO(2max)), respiratory compensation threshold as a percentage of VO(2max) (RCT), and VO(2) at RCT ( Vdot;O(2RCT)) were determined during a maximal Bruce treadmill protocol. VO(2max) (ml x kg(-1) min(-1)) was significantly greater ( P<0.
