Effects of Oral Creatine Supplementation on Power Output during Repeated Treadmill Sprinting.

The aim of the present study was to examine the effects of creatine (Cr) supplementation on power output during repeated sprints on a non-motorized treadmill. Sixteen recreationally active males volunteered for this study (age 25.5 ± 4.

Effects of active and passive recovery on performance during repeated-sprint swimming.

The effect of active and passive recovery on repeated-sprint swimming bouts was studied in eight elite swimmers. Participants performed three trials of two sets of front crawl swims with 5 min rest between sets. Set A consisted of four 30-s bouts of high-intensity tethered swimming separated by 30 s passive rest, whereas Set B consisted of four 50-yard maximal-sprint swimming repetitions at intervals of 2 min.

Reproducibility of the growth hormone response to sprint exercise.

Objective: There is a large inter-individual variation in the growth hormone (GH) response to exercise, but within-individual variation is unknown. The purpose of this study was to determine the reproducibility of the GH response to a single 30 s sprint on a cycle ergometer.

Design: Eleven non-obese male volunteers completed two trials separated by at least seven days during which they completed a single all-out 30 s sprint on a cycle ergometer followed by 60 min of rest.

Physiological Responses of Endurance-Trained Male Wheelchair Athletes to a 10-Kilometer Treadmill Time Trial.

The purpose was to examine selected physiological responses of endurance-trained male wheelchair athletes in different Paralympic racing classes (T2, n = 3; T3, n = 8; T4, n = 7) during a 10-km treadmill time trial (TM:10-km). Peak oxygen uptake (V̇O) was determined, and a TM:10-km was completed on a motorized treadmill. From this, % V̇O utilized and the relationship between V̇O and TM:10-km were established.
