Electromyographic Analysis Of The Infraspinatus And Deltoid Muscles During Shoulder External Rotation Exercises With And Without A Towel Roll, Kazuto Sakita

Theses and Dissertations

Standing and sidelying external rotation exercises produce high activation of the deltoid and infraspinatus. Holding a towel roll under the arm at 30° shoulder abduction during these exercises may decrease deltoid activity and increase infraspinatus activity. The objective was to determine if the addition of a towel under the arm during standing and sidelying external rotation affects EMG activity of the infraspinatus, middle and posterior deltoid, and pectoralis major, compared to the no towel condition. 20 male volunteers (age; 26 ± 3, height; 1.80 m ± .07 m, weight; 77 kg ± 10 kg) had right dominant hand, bilaterally healthy …

Kinematic Changes Of The Tennis Forehand Ground Stroke As Post Contact Ball Speed Increases, Merrill D. Funk

Theses and Dissertations

Neuromuscular and kinematic patterns during the tennis forehand have been studied extensively. However, no one has evaluated potential upper-extremity kinematic changes during the forehand as ball speed increases. The purpose of this study was to evaluate changes in shoulder and trunk kinematics as forehand ball speed increased, in an attempt to better understand how kinematics may promote forehand ball speed. Peak trunk rotation angle, shoulder horizontal abduction/adduction and internal/external rotation angle, and corresponding angular velocities were measured between initial backswing and ball contact during forehands that were performed at three different speeds (50%, 75%, and 100% of maximal post-impact ball …

Evaluation Of Metabolic Stress Between Jumping At Different Cadences On The Digi-Jump Machine, Thomas S. Lyons, James W. Navalta, Zachary J. Callahan

International Journal of Exercise Science

The American College of Sports Medicine (ACSM) recommends that healthy adults achieve a minimum of thirty minutes of moderate intensity aerobic exercise five days per week. While cycling, walking, and jogging are commonly observed methods of achieving these recommendations, another option may be repetitive jumping. The purpose of this study was to examine the metabolic responses between repetitive jumping at a cadence of 120 jumps per minute (JPMs) vs. 100 JPMs when utilizing the Digi-Jump machine. Twenty-eight subjects completed two jumping trials, one at 120 JPMs and one at 100 JPMs. Subjects jumped until volitional exhaustion, or for a maximum …

Aerobic And Anaerobic Changes In Collegiate Male Runners Across A Cross-Country Season, Cory W. Baumann, Thomas J. Wetter

International Journal of Exercise Science

The purpose of this study was to assess the physiological characteristics of trained NCAA Division III male runners across a competitive season of cross-country. Eight male distance runners (age 20.6±1.4 y) were administered a battery of aerobic and anaerobic laboratory tests at the beginning and end of an 8-10 week racing season. Aerobic testing included maximal oxygen uptake (VO2max), running economy (RE), ventilatory threshold (VT) and the onset of blood lactate accumulation (OBLA). Anaerobic testing consisted of the vertical jump (VJ) and the Wingate test. Final testing revealed anaerobic Wingate peak power significantly declined (11.8±1.1 to 10.7±1.0 W·kg-1) (P = …

Effect Of Single Set Dynamic And Static Stretching Exercise On Jump Height In College Age Recreational Athletes, Jeffrey C. Murphy Dr., Elizabeth F. Nagle, Robert J. Robertson Dr., Jean L. Mccrory Dr.

This study examined the effects of single set dynamic and static stretching on vertical jump height and hip and knee range of motion in a sample of college age recreational males. Forty-two males (aged 18-24) healthy, physically active volunteers participated as subjects in this investigation and were randomly assigned to one of three groups (1 set of 20 seconds dynamic stretch, 1 set of 20 second static stretch, or control). The knee and hip range of motion, sit and reach, and jump height were measured before and after the treatment condition. The same measures were performed on the control group …

Challenging The Accuracy Of A Single-Test Lactate Threshold Protocol In Collegiate Rowers, Erica A. Soma, Michael M. Lockard, Stasinos Stavrianeas

International Journal of Exercise Science

Elite rowers use lactate threshold (LT) estimates as a basis for training intensity in order to achieve the greatest training volume. For convenience, LT is usually determined in a maximal LT/VO_2max test. This simultaneous test is problematic because it requires a large power increment, which may not give the most accurate LT. PURPOSE: To challenge the validity of a simultaneous LT/VO_2max test to estimate LT in rowers. METHODS: Collegiate rowers (n=20, 16F and 4M, age 19.3±1.3 years, height 171.5±7.1 cm, weight 70±14 kg, VO_2max 44.6±5.5 ml•kg^-1•min^-1) performed two LT tests. Participants completed an …

Racial/Ethnic Differences In Bone Mineral Density Of Young Adults, Linda D. Wilkin, Tristan D. Sims, Matthew C. Jackson, Bryan L. Haddock

International Journal of Exercise Science

An estimated 1.5 million people suffer a bone disease-related fracture every year. Most work investigating bone mineral density (BMD) focuses on post-menopausal females but a report from the Surgeon General in 2004 stated that of particular concern are men, racial and ethnic minorities, poor individuals, individuals with disabilities, and individuals living in rural areas. The purpose of this study was to examine the racial/ethnic differences in bone mineral density of young adults and to investigate any correlations with variables suggested to influence BMD. BMD was assessed at a younger age than most studies based on the assumption that osteoporosis is …

The Association Between Soft Drink Consumption And Body Fat In Females Age 16 To 24, Megan M. Costello, Kate A. Heelan, Deborah A. Mowry, Bryce Abbey

International Journal of Exercise Science

American soft drink consumption (SDC) has increased since the 1960’s surpassing all other kinds of beverage consumption. In recent years, the scientific literature has suggested that SDC has been linked to the rising epidemic of obesity in children and adolescents. However, there is lack of information in scientific literature on the effects of SDC on body fat (BF%) in young females. The purpose of this study was to determine the association between SDC and BF% in young women, ages 16-24 years. Sixty-six females were asked to complete a 3-day food record, food frequency questionnaire, and an assessment BF% by dual-energy …

An Investigation Of Lower-Extremity Functional Asymmetry For Non-Preferred Able-Bodied Walking Speeds, John Rice, Matthew K. Seeley

International Journal of Exercise Science

Functional asymmetry is an idea that is often used to explain documented bilateral asymmetries during able-bodied gait. Within this context, this idea suggests that the non-dominant and dominant legs, considered as whole entities, contribute asymmetrically to support and propulsion during walking. The degree of functional asymmetry may depend upon walking speed. The purpose of this study was to better understand a potential relationship between functional asymmetry and walking speed. We measured bilateral ground reaction forces (GRF) for 20 healthy subjects who walked at nine different speeds: preferred, +10%, +20%, +30%, +40%, -10%, -20%, -30%, and -40%. Contribution to support was …

Riding Position And Lumbar Spine Angle In Recreational Cyclists: A Pilot Study., Samantha J. Schulz, Susan J. Gordon

International Journal of Exercise Science

This pilot study investigated the reliability of an inclinometer to assess lumbar spine angle in three different cycling positions, and explored the relationship between lumbar spine angle and riding position, anthropometry, bike measures and low back pain (LBP).

Cyclists were recruited from two cycle clubs. Anthropometric variables and bike set-up were measured before participants’ bikes were secured in a wind trainer. Cyclists then adopted three positions for riding, upright on the handlebars, on the brake levers and on the drops, according to a random allocation. The angle of the lumbar spine was measured, using an inclinometer, at zero minutes and …

Type Of Encouragement Influences Peak Muscle Force In College-Age Women, Ruth M. Amagliani, John K. Petrella, Alan P. Jung

International Journal of Exercise Science

Purpose: To investigate if the type of encouragement during a maximal voluntary isometric contraction (MVIC) had an influence on peak muscle force in strength-trained versus untrained collegiate women. Methods: Eleven strength-trained (20.4 + 1 yr) and twelve untrained (20.8 + 1 yr) women participated in three, five-second MVICs of seated knee extension. The three trials consisted of verbal only encouragement, verbal + visual encouragement, and verbal + pain avoidance encouragement. In all three trials, the participants received the same verbal encouragement. Trials were counterbalanced to minimize any possible order effects. A repeated measure ANOVA was used to analyze data. Any …
