The Biomechanical Effects of Percussive Therapy Treatment on Jump Performance.

Percussive therapy treatment is one form of myofascial release that has gained popularity amongst the sport community. It has been suggested that percussive therapy treatment may improve range of motion and improve athletic performance, but these claims are largely anecdotal. Currently, the effects of percussive therapy treatment on performance of athletic tasks is relatively unknown.

Male-Female Differences in Push-up Test Performance at Various Cadences.

Rozenek, R, Byrne, JJ, Crussemeyer, J, and Garhammer, J. Male-Female Differences in Push-up Test Performance at Various Cadences. J Strength Cond Res 36(12): 3324-3329, 2022-Push-up (PU) testing is widely used to assess upper-extremity muscular endurance.

Field Test Performance of Junior Competitive Surf Athletes following a Core Strength Training Program.

Lower body and core muscular strength are essential for optimal performance in many sports and competitive surfers have similar strength demands when maneuvering a surfboard to achieve competition success. Presently, the use of unstable surfaces is excessively utilized by surf coaches and trainers and to date, research does not support this as an effective training method for long-term improvements. Therefore, the purpose of this study was to determine the effectiveness of an 8-week Core Strength Training Program (CSTP) on a battery of field tests specific to assessing core musculature and lower body strength for junior competitive surf athletes.

The Effect of a Single Bout of Surfing on Exercise-Induced Affect.

Exercise-induced affect (EIA) has been well documented and is often composed of positive affect, negative affect, tranquility, and fatigue. Research on EIA has focused on mainstream sports such as running, walking, or cycling; however, no research has evaluated the influence of action sports participation in activities such surfing on EIA. The current study examined the effect of a single 30-min surfing bout on EIA in 107 adult volunteers.

Anthropometry and barbell trajectory in the snatch lift for elite women weightlifters.

The primary objective of this study was to examine relationships between anthropometry and horizontal barbell displacement during the pulling phase of the snatch lift (SN) in elite women weightlifters. Secondary objectives included description of anthropometric and displacement characteristics, and examinations of SN performance and competitive experience. Thirty-six women weightlifters competing at the 2009 Pan American Championships participated.

Effects of delayed onset muscle soreness on selected physiological responses to submaximal running.

This study examined the effects of delayed-onset muscle soreness (DOMS) on selected physiological responses to submaximal exercise. Seven male and four female subjects (Ss) aged 21-37 years completed two submaximal running sessions at an individualized pace corresponding to a blood lactate concentration (bLa) of approximately 2.5 mmol x L(-1).

Validity of the Caltrac Accelerometer in Estimating Energy Expenditure and Activity in Children and Adults.

The Caltrac accelerometer functions as either an activity monitor that provides activity counts based on vertical acceleration as the individual moves about, or as a calorie counter in which the acceleration units are used in conjunction with body size, age, and sex to estimate energy expenditure. This study compared VO based energy expenditure with Caltrac estimated energy expenditure during three speeds of treadmill walking in children and adults. It also tested the validity of the Caltrac to differentiate between high and low levels of walking activity (activity counts).
