And if so, how much does it increase these?

but what about aerobic exercise?

also..

After resistance exercise, serum IGF-1 was increased significantly (p<0.01) by 28% in R1 and 16% in R2 compared to pre-exercise levels. Resistance exercise did not increase serum VEGF at any time point.

A number of intervention studies have shown increased [18–23], decreased [24, 25], or unaltered [26,27] levels of IGF-I after endurance or resistance training. Similarly, many cross-sectional observational studies have examined the association of physical activity with IGF-I levels in the general population; however, their findings have been inconsistent [28–32]. Additionally, some reports have shown that circulating levels of IGFBP-1 and IGFBP-3 are also modulated with exercise [23, 33, 34], whereas other groups saw no effects in their levels with moderate-intensity aerobic exercise or strength training [35, 36]. The different responses of IGF axis hormones to the intensity and/or duration of various types of exercise could be the reason why exercise is not necessarily protective against all forms of cancer. Furthermore, it also has been reported that very heavy exercisers demonstrate high mortality ratios for lung, colorectal, and pancreatic cancers [37].

Nindl and Pierce have described in their recent review that the fact that there are studies claiming that both increases and decreases in IGF-I concentrations have beneficial effects on health presents a contradictory situation. Furthermore, they also stated that, even though local IGF-I is consistently up-regulated with both acute and chronic exercises, circulating IGF-I may actually decrease [56]. However, despite lowering IGF-I, the current exercise program would be expected to have beneficial effects on all of these various conditions

Hello!

At a minimum for a boost to your hormone production and HGH:

Do a heavy amount of sprints on a field, at a maximum of every 5 to 7 days.

Also, do heavy load on your muscles and system.
An example would be: Pushups that are hard for you, to where you can only do about 5 to 10 and then get exhausted.

So do push ups on your knees, regular, or feet up in the air on the bed or couch; to where you can only do 5 to 10 reps and feel exhausted and really pushing it to the max.

If you follow up heavy sprint cardio or muscle exercises with a:

Strong paleo type sleep, of no light sources + sleeping with no alarm, you should have strong natural hormone production through your sleep.

Best of luck to you, and I will try to add more!
