–The aim of this study was to determine if rating of perceived exertion (RPE) could be used to monitor the internal load during compounded circuit training (CCT) sessions in women. Thirteen young adults women performed three sessions of CCT varying the intensity according to participants’ maximum heart rate (50, 70 and 90%HRmax). Throughout the main part of CCT (35min), HR and RPE were measured...
The purpose of this study was to compare the blood lactate (La-), heart rate (HR) and percentage of maximum HR (%HRmax) responses among the small-sided games (SSGs) in elite young soccer players. Sixteen players (average age 15.7 6 0.4 years; height 176.8 6 4.6 cm; body mass 65.5 6 5.6 kg; VO2max 53.1 6 5.9 ml · kg(-1) · min(-1); HRmax 195.9 6 7.4 b · min(-1)) volunteered to perform the YoYo in...
PURPOSE High-intensity interval training (HIIT) is documented to yield effective improvements in the cardiovascular system and be an excellent strategy for healthy aging. However, it is not determined how age may affect the training response of key components of aerobic endurance. METHODS We recruited 72 males (mean ± SD, weight = 84.9 ± 12.9 kg, height = 180.4 ± 5.8 cm) and 22 females (weigh...
OBJECTIVES (a) To assess the validity and reliability of producing and reproducing a given exercise intensity during cycle ergometry using a braille version of Borg's standard 6-20 rating of perceived exertion (RPE) scale, and (b) to determine whether the exercise responses of blind participants, at a given produced RPE, were similar to those reported in recognised guidelines for sighted subjec...
background: high intensity interval training (hiit) is a novel training method which has received most attention in recent years. the aim of this study was to examine the effect of 8 weeks of high intensity interval training (hiit) on plasma levels of adiponectin and leptin in overweight nurses. m aterials and methods: 27 nurses (mean age 25.81±60 years, height 158.01±67 cm and weight 69.41±25 ...
This study assessed age-related changes in power and heart rate in 114 competitive male cyclists age 15-73 years. Participants completed a maximal Kingcycle ergometer test with maximal ramped minute power (RMPmax, W) recorded as the highest average power during any 60 s and maximal heart rate (HRmax, beats/min) as the highest value during the test. From age 15 to 29 (n = 38) RMPmax increased by...
The aim was to investigate the effects of concurrent exercise at moderate (MO) and light (LI) intensity on post-exercise hypotension (PEH). Ten women with borderline hypertension were submitted to the experimental procedure consisting of three sessions. In the MO session, the participants ran on the treadmill for 22 minutes at 65% of HRmax and then performed 5 resistance exercises against resis...
This study aimed to establish feasibility for myocardial speckle tracking (MST) and intra-observer reliability of both MST and tissue velocity imaging (TVI)-derived right ventricular (RV) strain (ϵ) and strain rate (SR) at rest and during upright incremental exercise. RV ϵ and SR were derived using both techniques in 19 healthy male participants. MST-derived ϵ and SR were feasible at rest (85% ...
BACKGROUND Distance running performance is a viable model of human locomotion. METHODOLOGY/PRINCIPAL FINDINGS To evaluate the physiologic strain during competitions ranging from 5-100 km, we evaluated heart rate (HR) records of competitive runners (n = 211). We found evidence that: 1) physiologic strain (% of maximum HR (%HRmax)) increased in proportional manner relative to distance completed...
PURPOSE This study examined the validity of a squash-specific test designed to assess endurance capability and aerobic power. METHODS Eight squash players and eight runners performed, in a counterbalanced order, incremental treadmill (TT) and squash-specific (ST) tests to volitional exhaustion. Breath-by-breath oxygen uptake was determined by a portable analyzer and heart rate was assessed te...
