The purpose of this investigation was to examine the validity of regulating exercise intensity using ratings of perceived exertion (RPEs) during arm crank and leg cycle exercise at 50 and 70% peak oxygen consumption (V˙O2peak). Ten men and seven women [26 (1) years old; mean (SE)] participated in this study. Each subject completed a maximal estimation trial(More)
PURPOSE The present investigation was undertaken to compare metabolic and perceptual responses between exercise performed at constant intensity (CON) and with a Spinning protocol of variable intensity (VAR). METHOD Fifteen subjects, including seven males and eight females (23 +/- 5 yr, 72 +/- 17 kg, and 171 +/- 10 cm), underwent two experimental trials.(More)
Anaerobic exercise is involved in many recreational and competitive sport activities. This study first established regression equations to predict maximal anaerobic power and then cross-validated these prediction equations. Using stepwise multiple regression analysis prediction equations for relative (watts per kilogram of body mass) and absolute (watts)(More)
Level and incline backward treadmill walking techniques are used in the rehabilitation of certain lower extremity injuries (eg., anterior cruciate ligament reconstruction). Of interest to clinicians is the maintenance of cardiorespiratory fitness resulting from these activities. The purpose of the present study was to determine the cardiorespiratory and(More)
The present investigation was undertaken to examine whether maximal oxygen uptake ( $$ \dot V{\rm O}_{{\rm 2max}} $$ ) and anaerobic threshold (AT) measured during incremental treadmill exercise would be affected by the exercise protocol in trained and untrained individuals. Fifteen untrained men, 10 untrained women, and 12 trained individuals participated(More)
PURPOSE The present study was undertaken to compare cardiorespiratory, metabolic, and perceptual responses to upper body exercise on an arm ergometer (AE) and a modified leg ergometer (LE). METHODS Seventeen male and seven female subjects completed two experimental trials. During each trial, the subjects performed two successive 8-min steady-state arm(More)
STUDY DESIGN A within-subject experimental design. OBJECTIVES To compare the magnitude of metabolic and cardiorespiratory changes produced during box lifting and lowering among combinations of lift technique (leg lift and leg-torso lift) and lift weight (10.8 and 15.4 kg). BACKGROUND Continuous box lifting and lowering can be used as an exercise in a(More)
The purpose of this study was to compare cardiovascular fitness between obese and nonobese children. Based on body mass index, 118 were classified as obese (boys [OB] = 62, girls [OG] = 56), while 421 were nonobese (boys [NOB] = 196, girls [NOG] = 225). Cardiovascular fitness was determined by a 1-mile [1.6 km] run/walk (MRW) and estimated peak oxygen(More)
To examine whether the validity of perception-based intensity regulation would be affected by exercise duration, 20 subjects were recruited to complete a maximal exercise test (GXT) and four submaximal trials of varying duration and intensity using a cyle ergometer. During GXT, ratings of perceived exertion (RPE), oxygen uptake (VO2), heart rate (HR), and(More)
