Recovery Heart Rate Variables Between Sprinters and Long Distance Female Runners
Introduction
This is an 8 weeks research proposal titled “Recovery heart rate between sprinters and long distance runners”. The main purpose of this research is to measure the recovery heart rate between a sprinter and long distance runner after a 5 minutes run in a treadmill. Heart rate recovery immediately after exercise is associated with a lower risk of cardiovascular disease and coronary heart disease (Morshedi-Meibodi, Larson, Levy, O’Donnell &Vasan, 2002).
Sprinting is an athletic sport in the track category running over a very short distance in a limited time. It is very powerful and covers a distance of 400 meters or less (Platt, 2015) while long distance running also known as endurance running which is largely aerobic is a continuous running covering a distance of at least 3km and more (Jones, 2006). Long distance requires a lot of mental strength as well as stamina (Jones, 2006). Every muscle contains two types of fibers- fast and slow twitch. Fast twitch fibers fatigue quickly due to it producing fast contractions (Hoefs, 2015). So as a result long distance runners contain huge amount of slow twitch muscle fiber whereas a sprinter has fast twitch muscle fiber (Hoefs, 2015). There are a lot of physiological differences between those two different athletics event. For example the difference in the fiber types (as mentioned above), muscle size, architecture of leg muscles, cardiovascular capacity as well as metabolic pathways and heart rate. Further information on this will be provided in the discussion section about those differences.
