Dear Kujhawk1978,
I was an elementary school physical educator who was very interested in the P.E. research concerning cross lateral movements, hamstring and quadracep muscular strength and muscular endurance engagement and the brain pathways and their relationship to reading comprehension. I have never studied the peer reviewed research literature concerning adult males and Testesterone levels and engagement of the Hamstrings and Quadraceps and the possible impact of such aerobic and anerobic exercise upon those Testesterone levels. I must say, I am too old, slow, and worn out to follow this intellectual inquiry, but perhaps one of you gentlemen or your loved one would spend some time looking into the question.
I am happy for you; that you can push your body and enjoy the sights and soumds not only of Nature as you travel through it, but the pulse of your heart as you push it through your exertion levels, the heavy and rapid breathing as you push yourself over steeper terrain and the joy in the accomplishment when completing your physical activity hopefully, daily. You and your experience would suggest that their may be a correlation between long periods of aerobic exercise involving the hamstring and quadracep muscles and an increase in male testesterone for prostate cancer survivors who have used Lupron as a method of ADT (Androgen Deprivation Therapy). Congratulations on your journey to vitality and vigor; I am most happy for you and the hope of possibility it illuminates for many of us. God Bless you all.
