Psychosocial Correlates Of Physical Activity In Children And Adolescents In A Rural Community Setting, Kelly Crimi†, Larry D. Hensley‡, Kevin J. Finn‡

International Journal of Exercise Science

The purpose of this study was to evaluate the relationships between selected psychosocial factors and the physical activity behaviors of children (grade 4-8) and adolescents (grades 9-12) in a rural community setting. The Children’s Physical Activity Scale (CPAC)was used to measure the psychosocial factors of physical activity, The Physical Activity Questionnaire-Children (PAQ-C), and Physical Activity Questionnaire-Adolescents (PAQ-A) were used to measure the physical activity behaviors of the 167 participants. Results indicated that male and female physical activity behaviors were not significantly different. However, physical activity declined with age [F(8,147) = 5.44, p < 0.05, ES = 0.23]. All psychosocial factors were significantly correlated with physical activity in youth with the single highest correlation for males being “liking of exercise” (r = .61) and the highest correlation for females was “liking of games and sports”(r = .44). Stepwise regression analyses identified three subscales (liking of games and sport, liking of exercise, and parental support) in a significant prediction model of physical activity in both genders. The results indicate that children's physical activity is associated with a variety of psychosocial variables that represent import predisposing and reinforcing factors.

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

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 …

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 …

Predicting Vo2max In College-Aged Participants Using Cycle Ergometry And Nonexercise Measures, David E. Nielson

Theses and Dissertations

The purpose of this study was to develop a multiple linear regression model to predict treadmill VO2max scores using both exercise and nonexercise data. One hundred five college-aged participants (53 male, 52 female, mean age 23.5 ± 2.8 yrs) successfully completed a submaximal cycle ergometer test and a maximal graded exercise test (GXT) on a motorized treadmill. The submaximal cycle protocol required participants to achieve a steady-state heart rate (HR) equal to at least 70% of age-predicted maximum HR (220-age), while the maximal treadmill GXT required participants to exercise to volitional fatigue. Relevant submaximal cycle ergometer test data included a …

Variations In Running Form Among Female Sprinters, Middle, And Distance Runners, Ruthann Cunningham

Theses and Dissertations

In the sport of track and field, runners excel at their events due not only to physiological characteristics but aspects in their form. Characteristics in form help runners achieve the goal in completing their event in the least amount of time possible. For sprinters, this is done by having a shorter swing phase and ground time along with greater power and a longer stride length. Distance runners accomplish the goal of quicker speeds by balancing it with running economy by spending greater time on the ground with shorter stride lengths compared to those in shorter distance running events. Middle distance …

The Effects Of Whole Body Vibration Platform Training On Hamstring Flexibility, Travis A. Epperson

Theses and Dissertations

Introduction: Very few studies have looked at the effect of vibration on flexibility, and no studies exist that have looked at stretching concurrently with whole body vibration (WBV) training. Therefore, the purpose of this study was to determine if whole-body-vibration training (WBV) done concurrently with static stretch (SV) is more effective than static stretching alone (SS), and to see if WBV training independently (SQ) improves hamstring flexibility without stretching. A secondary purpose of this study is to determine if retention of flexibility gains are maintained. Methods: Forty-four subjects (31 men, 13 women) completed this study (age 22.5 ± 1.8 years; …

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 …
