Aim:
The aim of this study was to investigate the relationship between maximal oxygen uptake (Vo(2max)) and repeated sprint ability (RSA) using non-motorised treadmill ergometry.
Methods:
Ten male participants (mean [standard deviation] VO(2max): 57.5 [2.1] mL x kg(-1).min(-1)) completed a RSA test (10, 6-s sprints with 34-s recovery) on a non-motorised treadmill. Oxygen consumption (VO(2)) and heart rate (HR) were measured during the RSA test and the decrement of performance fatigue (%(d)) was calculated for the performance indices mean maximal speed (MxSp) and average power output (AvPO).
Results:
There were significant relationships between VO(2max) and the %(d) MxSp (r=-0.75, P<0.05) and VO(2max) and the %(d) AvPO (r=-0.69, P<0.05). There were also significant relationships between VO(2max) and HR recovery (r=0.56, P<0.05) and VO(2max) and VO(2) recovery (r=0.7, P<0.01). However, while no significant relationships were reported between HR recovery and %(d) MxSp (r= 0.45, P>0.05) and HR recovery and %(d) AvPO (r=-0.52, P>0.05), significant relationships were observed between VO(2) recovery and %(d) MxSp (r=-0.75, P<0.05) and between VO(2) recovery and %(d) AvPO (r=-0.77, P<0.05).
Conclusion:
The findings of this study suggest that VO(2max) may be an important factor determining RSA during repeated, high-intensity running-based exercise, such as field hockey, rugby and soccer.

01:19Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart rate...
