Effect Of Self-Determination Theory-Based Strategies For Staging Recreation Encounters On Intrinsic Motivation Of Youth Residential Campers, Mark F. Roark, Gary D. Ellis Oct 2009

Effect Of Self-Determination Theory-Based Strategies For Staging Recreation Encounters On Intrinsic Motivation Of Youth Residential Campers, Mark F. Roark, Gary D. Ellis

Kinesiology and Health Science Faculty Publications

Parents and caregivers generally believe that the camp experiences they purchase for their children will not only yield transient pleasure and lasting memories of fun encounters, but significant developmental outcomes as well. Camp professionals serving over 11 million youths each year embrace such outcomes and commonly advance mission statements that point to the development of friendship skills, self-confidence, competence, self-reliance, independence, citizenship, and many other developmental outcomes. Empirical evidence of how these outcomes might be facilitated through specific recreation leadership strategies (e.g., activity staging) is lacking. The Self-Determination Theory (SDT) would suggest that youth leaders (e.g., camp counselors, recreation activity …

Neuropeptide Y And Neurovascular Control In Skeletal Muscle And Skin., Gary J Hodges, Dwayne N Jackson, Louis Mattar, John M Johnson, J Kevin Shoemaker Sep 2009

Neuropeptide Y And Neurovascular Control In Skeletal Muscle And Skin., Gary J Hodges, Dwayne N Jackson, Louis Mattar, John M Johnson, J Kevin Shoemaker

Kinesiology Publications

Neuropeptide Y (NPY) is a ubiquitous peptide with multiple effects on energy metabolism, reproduction, neurogenesis, and emotion. In addition, NPY is an important sympathetic neurotransmitter involved in neurovascular regulation. Although early studies suggested that the vasoactive effects of NPY were limited to periods of high stress, there is growing evidence for the involvement of NPY on baseline vasomotor tone and sympathetically evoked vasoconstriction in vivo in both skeletal muscle and the cutaneous circulation. In Sprague-Dawley rat skeletal muscle, Y(1)-receptor activation appears to play an important role in the regulation of basal vascular conductance, and this effect is similar in magnitude …

Effect Of Femoral Tunnel Placement For Reconstruction Of The Anterior Cruciate Ligament On Tibial Rotation, Stavros Ristanis, Nikolaos Stergiou, Eleftheria Siarava, Aikaterini Ntoulia, Grigoris Mitsionis, Anastasios D. Georgoulis

Journal Articles

Background: Rotational knee movement after reconstruction of the anterior cruciate ligament has been difficult to quantify. The purpose of this study was to identify in vivo whether a more horizontal placement of the femoral tunnel (in the ten o'clock position rather than in the eleven o'clock position) can restore rotational kinematics, during highly demanding dynamic activities, in a knee in which a bone-patellar tendon-bone graft had been used to reconstruct the anterior cruciate ligament.

Methods: We evaluated ten patients in whom a bone-patellar tendon-bone graft had been used to reconstruct the anterior cruciate ligament with the femoral tunnel in the …

Electromechanical Delay Of The Knee Flexor Muscles Is Impaired After Harvesting Hamstring Tendons For Anterior Cruciate Ligament Reconstruction, Stavros Ristanis, Elias Tsepis, Dimitrios Giotis, Nicholas Stergiou, Guiliano Cerulli, Anastasios D. Georgoulis

Journal Articles

Background

Changes in electromechanical delay during muscle activation are expected when there are substantial alterations in the structural properties of the musculotendinous tissue. In anterior cruciate ligament reconstruction, specific tendons are being harvested for grafts. Thus, there is an associated scar tissue development at the tendon that may affect the corresponding electromechanical delay.

Purpose

This study was conducted to investigate whether harvesting of semitendinosus and gracilis tendons for anterior cruciate ligament reconstruction will affect the electromechanical delay of the knee flexors.

Study Design

Case-control study; Level of evidence, 3.

Methods

The authors evaluated 12 patients with anterior cruciate ligament reconstruction …

High Intensity Running Results In An Impaired Neuromuscular Response In Acl Reconstructed Individuals, Kostas Patras, Giorgos Ziogas, Stavros Ristanis, Elias Tsepis, Nikolaos Stergiou, Anastasios D. Georgoulis

Journal Articles

Anterior cruciate ligament (ACL) reconstruction reestablishes electromyographic activity during moderate activities such as walking but is unclear if this is also the case in sports activities such as high intensity running that results in accumulation of metabolic fatigue. Nine bone-patella tendon-bone ACL reconstructed athletes were evaluated 19.2 (5.7) months post-operatively using a telemetric electromyographic system. The neuromuscular response of vastus lateralis and biceps femoris muscles was tested bilaterally on separate occasions during 10 min running at moderate intensity (20% below the lactate threshold) and 10 min running at high intensity (40% above the lactate threshold). During moderate intensity running, electromyographic …
