study finds aerobic exercise increased Testosterone levels in obese men.

exercise increases AMPK to improve insulin sensitivity and glucose uptake in new animal study.

Recovery doesn't just relate to exercise; recovery relates to travel.

ketogenic diet found to not deplete muscle glycogen in endurance athletes.  The metabolism of the endurance athletes can do this via the high fat oxidation--estimates of 80%.

Exercise, DHEA, and DHT increased GLUT4 uptake of glucose, increasing glycemic control.

fresh, young coconut water shown to be equal to sports drinks in rehydration from heavy exercise.

Lifestyle changes are the most effective therapy in Diabetes development.  These include, diet modification, weight loss, and exercise.

high intensity interval training versus steady state provides different results in post exercise FT.

Creatine loading dose of 25 grams over 4 days shown to increase high-intensity exercise performance in both males/females.

Mouse model finds that Cordyceps increased the interval to exhaustive exercise induced oxidative stress.  SOD, Cat, and GPx were increased in the low, intermediate, and high dose Cordyceps groups.  Oxidative stress markers MDA and 8-OHdG were lower in all groups

Increased risk of atrial fibrillation in men exercising more than 5 days per week.  The study looked at men 45-79.  In contrast, walking and bicycling later in life was associated with decreased risk.

After school fitness/exercise improved focus, attention, and cognition of children.

Meta analysis does find that diet and exercise (lifestyle changes) do reduce risk of diabetes.

BDNF increased metabolic biomarkers, MAPK, in hippocampus.  This has implications in the treatment of learning disorders.  Exercise has consistently been shown to be the most significant mechanism to increase BDNF.

Great review of macronutrients and insulin resistance.  Caloric reduction plus exercise still the best method to reduce insulin resistance.   Long-term high protein intake increases insulin resistance.

2.5 hours of moderate intensity exercise found to reduce cancer mortality.  The effect was even more profound in cancer survivors.  

Breast cancer survivors (BCS) exhibit decreased physical function and quality of life (QOL) following cancer treatments. Resistance training (RT) may elicit positive changes in physical and mental well-being. This study assessed 27 BCS, pre-and post-intervention (six months) on the following variables: muscular strength (via one repetition maximum (1RM) of chest press and leg extension), physical function (via the Continuous Scale-Physical Functional Performance test) and QOL (via the Short Form-36 survey). RT consisted of two days/week of ten exercises including two sets of 8-12 repetitions at 52%-69% of their 1RM. A repeated measures analysis of variance revealed BCS significantly (p < 0.05) increased upper (71 ± 22 to 89 ± 22 kg) and lower body (74 ± 18 to 93 ± 24 kg) strength, total physical function (65.5 ± 12.1 to 73.6 ± 12.2 units) and the subcomponents of physical function: upper body strength (63.5 ± 16.3 to 71.2 ± 16.8 units), lower body strength (58.5 ± 14.9 to 68.6 ± 16.3 units), balance and coordination (66.5 ± 12.2 to 74.6 ± 11.6 units), and endurance (67.2 ± 12.0 to 75.0 ± 11.6 units). No changes were observed over time for subjective measures of physical function and QOL. Results showed RT could be an effective means to improve objective physical function in BCS. Further research is needed to clarify the effects of RT on subjective physical function and QOL.
