Introduction Scientists believe that there are two important factors which influence endurance performance: VO˛max and OBLA (onset of blood lactate accumulation). However, athletes do not perform endurance exercise at their VO2max. "The exercise intensity at the point of OBLA consistently and powerfully predicts endurance exercise performance of men and women" (McArdle et al. 2001) A blood lactate threshold will determine the heart rate at which OBLA occurs in the athlete. By knowing the heart rate at which their blood lactate threshold occurs, the athlete may train at the intensity he/she requires for his/her workout (HASTC 2001). If an athlete can delay OBLA from occurring, then it will allow them to exercise closer to their VO2 max. "The closer an athlete is able to sustain exercise performance to their VO2 max without reaching their blood lactate threshold, increase the possibility that they will perform better or more efficiently" (HASTC 2001). There have been many...
