Effect Of Increasing External Loads On Countermovement Jump Landing Kinetics Between Ncaa Di Women's Soccer And Gymnastics On Land Vs In Water, Paul Bryan Beachem Iv
Effect Of Increasing External Loads On Countermovement Jump Landing Kinetics Between Ncaa Di Women's Soccer And Gymnastics On Land Vs In Water, Paul Bryan Beachem Iv
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The purpose of this study was to compare the effect of differing loads on landing kinetics on land, and in aquatic conditions. Twenty four NCAA DI athletes volunteered for this study twelve female soccer players and twelve female gymnasts. Participants performed three jumps with four differing external loads in both land and aquatic environments. External loads were body weight (BW), BW*1.1, BW*1.2, BW*1.3 and applied via a weighted vest. All external loads for both conditions were added based upon participants BW on land. Kinetic measures were peak force, rate of force development, and impulse of the landing phase of the …

Comparison Of Propulsive Power During Loaded Countermovement Jumps Performed In Water Versus Land In College Aged Males, Clint R. Nardoni
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
As use of an aquatic environment increases as a training and rehabilitative tool, the purpose of this study was to assess peak propulsive power in loaded countermovement jumps (CMJ) in water and compare them to loaded CMJ on land. 20 college aged (24.6±3.6 years) recreationally active males performed 4 randomized countermovement jumps on a force plate with increasing loads (bodyweight [BW], BW+10%, BW+20%, BW+30%) in two environments: immersed in water at the xiphoid process and on land. Peak power (PP) and mean power (MP) normalized to apparent mass were assessed for all jumps. A 2 (environment) by 4 (load) repeated …
Effect Of Water Immersion And Jet Perturbation On Balance In Older And Younger Adults, Matthew Baldwin
Effect Of Water Immersion And Jet Perturbation On Balance In Older And Younger Adults, Matthew Baldwin
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Background: Although balance exercises are often performed in shallow pools, the efficacy of this practice is not well understood. Purpose: To quantify the effect of water depth and jet intensity on measures of balance in older and younger adults. Subjects: Sixteen older (age = 62.8 °” 9.56 yrs) and fifteen younger (age = 22.5 °” 1.85 yrs) adults. Methods: Posturography data were collected as participants stood quietly for 90 seconds on land and at various water depths and jet intensities. Results: Main effects < 0.001) and pairwise comparisons revealed that all measurements increased with increasing water depth and jet intensity,with older adults increasing statistically less than younger adults at higher jet intensities. Conclusions: Water immersion to the xiphoid process and water jet intensities at or above 40% seem to be environmental conditions that produce the greatest postural sway.

Effect Of Aquatic Immersion On Static Balance, Talin J. Louder
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Objective To quantitatively assess measures of static balance and limits of stability (LOS) in an aquatic environment compared to on land. Methods Fifteen healthy, young adults (23 + or - 2 years) performed 90 s static balance trials on land and aquatic immersion at two different depths (greater trochanter, xiphoid process). Measures of 95% ellipse area and center of pressure (CoP) mean velocity were computed from the force data. Additionally, participants completed a visual analog scale (VAS) of perceived stability for each environmental condition. Following the static balance trials, participants performed anterior-posterior and medial-lateral LOS assessments. Results Significant differences in …
