• Very interesting that in this study of elite marathoners they're doing at least 2-3 fasted, low carb runs per week.
• Cumulative daily sleep of 7-9 hours might not be as important as total daily sleep of 7-9 hours.
• Doing your interval running on flat treadmill vs. uphill treadmill could be better!

Listener Q&A:

As compiled and read by Brock, the Ben Greenfield Fitness Podcast "sidekick".

Audio Question from AJ @ 00:18:23 He injured his hip playing indoor soccer. Very large bruise that stuck out about an 3/4 of an inch. When it healed it left a bump about the size of a quarter that he can move around with his finger. He thinks its a keloid (a type of scar which is composed mainly of collagen). He has had an xray and it is not a bone fragment. It bothers him after racing (can barely run). What can he do to minimize the pain and get ready for next season?

~ In my response to AJ, I mention Apple Cider Vinegar. I also mention Helichrysum Oil for reducing scars.

Audio Question from Cathy @ 00:26:12 She enjoys the way a cold bath or a soak in a lake/ocean makes her feel but she has doesn't know if it is right for her. Her naturopathic doctor told her that her detoxification pathways are not open, so she can't shed all the toxins out of her system, and has "toxic overload". Her naturopathic doc recommended that she do saunas to increase her sweating. The problem is that it is hard for her to sweat (needs to be 95-100 degrees) even in the sauna she needs to be jumping rope or something. She also has poor circulation and raynaud's syndrome. Should she be using cold therapy at all? Also, how can she increase her sweating, since exercise doesn't really make her sweat.

~ In my response to Cathy, I mention Sweet Sweat. I also mention this secretor test.

Audio Question from Charlie @ 00:50:47 He's been training for a couple marathons over the last 6-8 months. After each run he has noticed that his quads and calf muscles twitch uncontrollably (sometimes for days). Is this normal or is he lacking something in his nutrition?

Also Chrissy says: Do you know anything about a popcorn sensation in the calf muscle after running followed by severe muscle cramps? This started happening to me about 2 years ago after running a half marathon and now occurs after running even short distances (a couple miles) and, sometimes, after a bike ride. The cramping can get so severe that I feel like I did an intense calf workout. I’m 36 and have been running road races since I was in my early 20’s. Because of another injury to my hip, I’ve decided to take a break from running altogether. I want to return to running and tris once my hip gets better, however I do not want to feel like I have aliens living in my calves.

~ In my response to both Charlie and Chrissy, I mention topical magnesium.

Audio Question from Jeff @ 01:00:29 A few podcasts ago we talked about a very young girl who has been doing half marathons at a high level and Ben was concerned about that. Jeff's 10-year-old son is doing a short triathlon soon and loves to run and wants to "be like his dad". If he continues in his desire to run long distances (more than 3 miles at a time), is this something Jeff should reign him in on? He wants to encourage his son but not if it is detrimental to his development. What are your thoughts on youngsters in endurance sports and is there anything in particular he should be concentrating on nutritionally?

~ In my response to Jeff, I mention Lavamagazine.com.

Audio Question from Keith @ 01:10:24 He is planning to buy some liquid multivitamins that you recommended. He noticed that some of them are "for kids" and is wondering if there is a difference between then beyond flavour? Also, are there specific vitamins that children should be taking and is there any danger in giving an adult product to a child?

~ In my response to Keith, we discuss Kid's Liquid Multivitamins.

Audio Question from McKade @ 01:15:29 He is in the military and wants to know how to best increase his number of pushups, pullups, situps and chinups. What schedule would you recommend to increase these quickly.

~ In my response, I mention the Naked Warrior book and Ultimate Warrior Workouts.

Audio Question from Scott @ 01:22:25Wants to know what your take is on doing cold exposure before a workout. Is there any research that suggests that there would be an increase in strength output (reps or weight) or delayed muscle fatigue leading to greater work capacity.
