Relationship between laboratory measured variables and heart rate during an ultraendurance triathlon

The present study examined relationships between performance heart rate (HR) during an ultraendurance triathlon (UET), and HR corresponding to the first and second ventilatory thresholds (VT sub(1)HR and VT sub(2)HR), and the HR deflection point (HR sub(d)). One month prior to the UET, twenty-one ul...

Description
Summary:The present study examined relationships between performance heart rate (HR) during an ultraendurance triathlon (UET), and HR corresponding to the first and second ventilatory thresholds (VT sub(1)HR and VT sub(2)HR), and the HR deflection point (HR sub(d)). One month prior to the UET, twenty-one ultraendurance triathletes performed progressive cycle ergometry and treadmill running for the determination of VT sub(1)HR, VT sub(2)HR, and HR sub(d). Portable telemetry units recorded HR at 60 s increments throughout the UET. Mean HR during the cycle and run phases of the UET (148 plus or minus 9 and 143 plus or minus 13 bpm) were significantly (P
