The Short-Term Effect Of Whole Body Vibration Training On Physical Capabilities On Active Young Recreational Athletes, Esteban Martinez Ballester, Ivan Chulvi Dr

International Journal of Exercise Science: Conference Proceedings

In recent years, whole body vibration (WBV) has been the subject of a great amount of research towards improving physical capabilities as a postactivation potentiation because the muscle spindle’s sensitivity can be increased (Rittweger, 2010). Typically, WBV is realized by the subject above the platform in squat position while the platform oscillates at differences intensities and amplitudes. Previous reports have shown that WBV produces preconditioning effects that lead an increase of power and flexibility (Jacobs & Burns, 2009), but controversial data exists that have shown no positive effect if an optimal dosage is not used in a controlled manner (Wilcock …

The Effect Of Fatigue On Shoulder Muscle Strength Ratios In Collegiate Water Polo Players, Bobby Sanders, Steven A. Hawkins, Michele Leblanc

International Journal of Exercise Science: Conference Proceedings

Introduction: A proposed mechanism of shoulder injuries is imbalances in the strength of the shoulder muscles, however, the effects of fatigue on these imbalances are unknown. The purpose of this study was to investigate the relationship of isokinetic-induced fatigue on the development of shoulder muscle imbalances using both the conventional and functional ratio.

Knee Osteoarthritis And The Efficacy Of Kinesthesia, Balance & Agility Exercise Training: A Pilot Study, Matthew W. Rogers, Nauris Tamulevicius, Marius F. Coetsee, Beth F. Curry, Stuart J. Semple

International Journal of Exercise Science

Kinesthesia, balance and agility (KBA) neuromuscular exercises are commonly used for rehabilitation of lower extremity injuries. KBA combined with strength training (ST) reportedly improves function among persons with knee osteoarthritis (OA), but independent effects of KBA are unknown. The purpose of this study was to determine the efficacy of KBA exercises, independent of ST, to improve function among persons with knee OA. Twenty participants (69.3, SD 11.4 y) were randomized to 8 weeks, 3-days per week, instructor-lead KBA or ST groups. Self-reported physical function (difficulty with daily living activities such as walking, bending, stair climbing, etc.) was measured at baseline …

Differences In Heart Disease Risk Perception And Actual Cardiac Risk In Men Vs. Women, Amanda K. Dietz, Steve Martin, Becky Braden, Thomas Meade, Kathy L. Hill, Stephen F. Crouse, John S. Green

International Journal of Exercise Science: Conference Proceedings

Differences in Heart Disease Risk Perception and Actual Cardiac Risk in Male vs. Female Cardiac Patients Amanda Dietz, Julie Borsack, Steve Martin, Kathy L. Hill, Thomas Meade, Stephen F. Crouse, FACSM, and John S. Green, FACSM Texas A&M University, College Station, TX (Sponsor: John S. Green, FACSM)

PURPOSE: To describe gender differences in both risk perception and actual coronary risk in patients with coronary artery disease (CAD). METHODS: 33 females and 67 males with documented CAD completed a questionnaire designed to assess CAD risk perception. They also underwent assessments for all ACSM risk factors. Five-point Likert scale responses to the …

Effect Of Plasma Donation On Responses To Exhaustive Severe Intensity Cycle Ergometer Exercise, John H. Curtis, David W. Hill, Samantha Burdette, Jakob Vingren

International Journal of Exercise Science: Conference Proceedings

PURPOSE: The purpose of this study was to investigate the time course of the effects of plasma donation on responses to severe intensity exercise. METHODS: Four women (mean ± SD: age, 27 ± 7 years; height, 163 ± 13 cm; weight, 62.9 ± 12.0 kg) and six men (age, 25 ± 2 years; height, 180 ± 6 cm; weight, 87.3 ± 6.2 kg) performed exhaustive cycle ergometer tests under control conditions, and then 2 h, 2 d, and 7 d following plasma donation. RESULTS: Times to exhaustion at baseline and 2 h, 2 d, and 7 d following plasmapheresis were …

The Effect Of Pedaling Cadence On The Kinetics Of Oxygen Uptake During Severe Intensity Exercise, Jennifer L. Sylvester, Samantha D. Burdette, David W. Hill, Jakob L. Vingren

International Journal of Exercise Science: Conference Proceedings

During exhaustive severe intensity exercise, the oxygen uptake (VO2) increases exponentially, with a time constant of ~30 s. After ~1 to 2 min, a slow component emerges and drives the VO2 to its maximum. Pedaling cadence contributes to the metabolic demand at a given work rate and affects several responses to cycling exercise. PURPOSE: To determine the effect of pedaling cadence on parameters of the two-component VO2 response profile during severe intensity exercise. METHODS: Eight women (mean ± SD: age 22 ± 1 yr, height 161 ± 6 cm, and weight 58.8 ± 2.3 kg) and 10 men (age 23 …

The Effectiveness Of The Critical Power Model On Prescribing Elements Of Intermittent Exercise, Patrick G. Keenan, Scott P. Mclean, Jimmy Smith

International Journal of Exercise Science: Conference Proceedings

Intermittent exercise is a valuable method of training, consisting of numerous interrelated factors. The critical power model has been used to administer interval training programs; however, it has not been used to accurately prescribe elements of intermittent exercise. PURPOSE: This study aimed to use individual critical power models to prescribe elements of intermittent exercise. METHODS: Ten male athletes, mean (sd) age and mass 19.6 (1.4) years and 77.8 (8.1) kg performed three phases of testing on a cycle ergometer: 1) familiarization, one learning trial to establish a starting point for subsequent tests; 2) establishment of individual W/t relationship from [Eq …
