Timing Carbohydrate Beverage Intake During Prolonged Moderate Intensity Exercise Does Not Affect Cycling Performance, George G. Schweitzer†, John D. Smith‡, James D. Lecheminant‡
Timing Carbohydrate Beverage Intake During Prolonged Moderate Intensity Exercise Does Not Affect Cycling Performance, George G. Schweitzer†, John D. Smith‡, James D. Lecheminant‡
International Journal of Exercise Science
Carbohydrate beverages consumed during long-term exercise have been shown to attenuate fatigue and improve performance; however, the optimal timing of ingestion is unclear. Therefore, the purpose of this study was to determine if timing the carbohydrate ingestion (front-loading (FL), continual loading (CL), and end-loading (EL)) during prolonged exercise influenced exercise performance in competitive cyclists. Ten well-trained cyclists completed three separate exercise bouts on a bicycle ergometer, each lasting 2 hours at an intensity of ~67% VO2 max, followed by a 15-minute “all out” time trial. In the FL trial, participants ingested a carbohydrate beverage during the first hour and …
Age-Related Differences In Systolic Blood Pressure Recovery After A Maximal-Effort Exercise Test In Non-Athletic Adults, Uchechukwu Dimkpa†, Andrew C. Ugwu‡
Age-Related Differences In Systolic Blood Pressure Recovery After A Maximal-Effort Exercise Test In Non-Athletic Adults, Uchechukwu Dimkpa†, Andrew C. Ugwu‡
International Journal of Exercise Science
The present study investigated the rate of systolic blood pressure recovery (SBPR) amongst three male age groups. Ninety-six apparently healthy, non-athletic adult males (48 young [23.91±4.58 years], 32 middle-aged [41.78±5.98 years] and 16 elderly [62.87±2.57 years]) participated in the study. Subjects performed a maximal-effort ergometer exercise test. Maximal oxygen uptake (VO2max) was measured during the exercise protocol; heart rate (HR) and SBP were measured before exercise (after 10 and 15 minutes of rest), during exercise (at 2-minute intervals), and at the first minute of post-exercise recovery and subsequently at 2-minute intervals until the recovery of SBP. Results showed that third-minute …
The Effects Of Music On Heart Rate And Perceived Exertion During 20 Minutes Of Treadmill Running, Tara Litz
The Effects Of Music On Heart Rate And Perceived Exertion During 20 Minutes Of Treadmill Running, Tara Litz
Undergraduate Theses and Capstone Projects
This study examined the effects of music on heart rate (HR) as well as ratings of perceived exertion (RPE-B) while running on a treadmill for 20 minutes. Research subjects included men and women, ages 18 to 25. All subjects completed a 20-minute treadmill run set at 5.0 mph with 0% grade. Omron heart monitors were used to measure and record subjects’ HR every 2 minutes after the start of the test. Subjects reported ratings of perceived exertion -using the Borg Scale- which was also recorded every two minutes throughout the test period. One treadmill session included music; the other session …

Kinesiology, Health and Sport Studies
The purpose of this study was to determine how physical education students' cardiovascular responses as determined by mean heart rate, standard deviation of heart rate, and percentage of time in target heart rate zone varied according to student characteristics. Participants were 505 students in Grades 3 through 12. The Polar Accurex Plus heart rate telemetry system was used to measure the physiological load on the cardiovascular system. Three-way ANOVA results suggested that heart rate patterns in physical education varied according to gender, grade, and activity. For example, secondary school girls were more active in individual activities while secondary school boys …
