Handgrip contribution to lactate production and leg power during high-intensity exercise.
PURPOSE The purpose of this study was to examine the upper-body contribution via handgrip to power profiles and blood lactate concentrations during high-intensity cycle ergometry. METHODS Nine trained male subjects each completed a 20-s high-intensity cycle ergometer test twice, in a random manner, using two protocols, with a handgrip (WG), and without handgrip (WOHG). Capillary (earlobe) blo...
متن کاملThe Effect of High Intensity Intermittent Exercise on Power Output for the Upper Body
The aim of the present study was to examine and measure high intensity, intermittent upper body performance, in addition to identifying areas of the body that affect the variance in total work done during the 5 × 6 s sprint test. Fifteen males completed an upper body 5 × 6 s sprint test on a modified electro-magnetically braked cycle ergometer, which consisted of five maximal effort sprints, ea...
متن کاملDietary regimen and performance of high intensity ergometer exercise.
The influence of preceding diet (mixed, MD; carbohydrate CD; protein PD) on performance during high intensity endurance cycling was examined in six middle distance runners. Subjects undertook cycle ergometer exercise at a workload equivalent to 80% VO2 max until exhaustion following each of the three dietary regimens. Dietary analyses were performed using a computerised evaluation technique and...
متن کاملRelationship of ergometer-specific VO2 max and muscle enzymes to blood lactate during submaximal exercise.
This study compared the relationship of maximum oxygen uptake and skeletal muscle enzyme activities to the submaximal exercise intensity eliciting 4 mM blood lactate (OBLA). Twelve subjects performed both cycle (Cy) and treadmill (Tr) submaximal exercise with step-wise increments each fourth minute. Blood lactate concentration and oxygen uptake (VO2) were determined during the final minute of e...

This study compared the relationship of maximum oxygen uptake and skeletal muscle enzyme activities to the submaximal exercise intensity eliciting 4 mM blood lactate (OBLA). Twelve subjects performed both cycle (Cy) and treadmill (Tr) submaximal exercise with step-wise increments each fourth minute.
