The main purpose of this study was to compare cycle ergometer training using low intensity and moderate in increasing the catecholamine hormone overweight females. This conducted on 50 females with mean age 22.44±2.97 years old body mass index between 25 kg.m.2 30 kg.m.2. Treatment given 4 times per week during 5 weeks periods Group 1 continuous (60%-70% HRmax), 2 (70%-80% HRmax). Heart rate mo...

Uridine is postulated to participate in the development of insulin resistance. Since exercise is an effective tool in the treatment of insulin resistance it appeared justified to assess the impact of maximal exercise on plasma uridine and insulin sensitivity indices (e.g. insulin and HOMA-IR) in healthy subjects. The study included forty-four healthy males (18.5+/-2.92 years, VO₂max 50.2+/-6.26...

The kinetics of post-exercise heart rate (HR) and oxygen consumption (EPOC) was studied in 10 elite cyclists subjected to four laboratory cycle ergometer maximal exercises lasting 30, 90, 180 or 360 s. Heart rate and oxygen uptake (VO2) were recorded over a period of 6 min after the exercise. By applying the logit transformation to the recorded variables and relating them to the decimal logarit...

DIMKPA U, UGWU AC, OSHI DC. Assessment of Sex Differences in Systolic Blood Pressure Responses to Exercise in Healthy, NonAthletic Young Adults. JEPonline 2008;11(2):18-25. Genderdifferences in systolic blood pressure (SBP) responses to maximal exercise have not been reported previously. We assessed genderdifferences in SBP during and after exercise in non-athletic young adults. Three hundred a...

Five female and five male subjects with no known cardiovascular abnormalities nor any neuromuscular disorders were examined during exercise on a cycle ergometer or a 30 min immersion in warm water with and without exercise to determine the effects of immersion on cardiac output, heart rate, blood pressure, forearm blood flow, muscle blood flow, skin blood flow and muscle relaxation. Muscle rela...

This study employed Stewart's physicochemical approach to quantify the effects of pregnancy and strenuous exercise on the independent determinants of plasma H+ concentration ([H+]). Subjects were nine physically active pregnant women [mean gestational age = 33 +/- 1 (SE) wk] and 14 age-matched nonpregnant controls. Venous blood samples and respiratory data were obtained at rest and during 15 mi...

This study was conducted to determine whether submaximal cardiovascular responses at a given rate of work are different in children and adults, and, if different, what mechanisms are involved and whether the differences are exercise-modality dependent. A total of 24 children, 7 to 9 yr old, and 24 adults, 18 to 26 yr old (12 males and 12 females in each group), participated in both submaximal a...
