ABSTRACT

Introduction: The resting heart rate (HR), resting arterial blood systolic pressure, diastolic pressure and mean arterial pressure; maximal power output (Pot_max), maximal index of power (IP_max); HR_max, maximal oxygen uptake (O2max) and maximal O₂ pulse (PulO_2max) of Mexican athletes of different sport profits were recorded, to test if endurance performance adjustments of different proportions can be distinguished between sport groups. Material and methods: Female volunteers practiced karate-do (n = 6), 1,500 dash meters (dm) (middle fond, n = 8), endurance (n = 10) and 100 m swimming (n = 8). They all performed an increasing ergometric test of maximum strength while seated on an electronic cycle-ergometer in an open spirometric system and at 2,240 m altitude. Results: All groups showed a positive relationship between PulO_2max and O_2max; however, it was negative between PulO_2max and HR_max for swimmers, and also negative between sport mean speed and HRresting for the endurance group. The post-hoc analysis showed similar HR_max, O_2max and PulO_2max in all sports groups. Karate-do showed greater HRresting and lower Pot_max and IP_max than swimming, 1,500 dm and endurance groups. Conclusion: The skeletal muscle (Pot_max, IP_max) and central (resting HR) indicators of endurance performance adjustments, were lower in karate-do compared to swimming, 1,500 dm and endurance groups. The inverse relationship between PulO_2max and HR_max was only significant among the swimming group.
