The question is : does the ability to recover decrease significantly , and does your ability to increase your endurance and flexibility decrease a lot??

I would think that your ability to improve local muscular endurance would also be hindered. Your body is less apt to store energy substrates while in a caloric deficit. You are depleting your body's energy stores, so improving endurance will definitely be tough. However, I think it is possible in the lesser trained individual via the proliferation of enzymes involved in energy production, therefore improving the efficiency of producing energy using what stores already exist.

I would think that flexibility training shouldn't be hindered to any significant extent. From what I understand, microtrauma to connective tissues isn't necessary to improve elasticity, but please correct me if I'm wrong. Neural factors also play a role in flexiblity and mobility, so the effect diet has on that part of the equation should be minimal to none.
