Document Summary

If an individual is working at high work rate for extended period of time (exc. 45 min run) y heart is generating significant pressures for an extended period of time. Every time person squats, systolic pb increases (close to 60) Over 10 repetitions peak systolic pressures get close to 210mmhg. After 3 min rest you see same increase. Even though stimulus is significant during exercise, it doesn"t last very long. Adaptation of the heart is much more dramatic than when going for a long run un) your. But cyclists have a greater ventricular diameter so they have a greater stroke volume. When you have a brief contraction, you don"t occlude as much blood flow. Over time, the left ventricular wall thickness hypertrophies s--> traction. Over time, the left ventricular wall thickness hypertrophies (much more so in the cyclist than in the resistance training athlete or runner) Left ventricular mass is similar to wall thickness --> lowest in strength athletes.
