Table 3:
A summary of notable studies that examined the acute and training effect of exercise on endogenous DHEA levels in old men and women. a DHEA= dehydroepiandrosterone; DHEA-S=Dehydroepiandrosterone sulfate; RE= resistance exercise; RET=resistance exercise training; AE=aerobic exercise; AET=aerobic exercise training; ↔= unchanged; ↑= increased; 1RM=1-rep maximum; 10RM=10-rep maximum; HRmax= maximum heart rate.
Author, Year | Exercise Duration | Exercise details | Gender | Age | Effect of exercise on DHEA |
---|---|---|---|---|---|
Hersey, 1994 270 | Training | RET: progressive whole body AET: progressive treadmill walking/jogging |
male and female | 70-79 | ↔ resting DHEA following 6 months of RET or AET. |
Copeland, 2002 267 | Acute | RE: 8 whole body exercises 3 sets, 10 reps at 10RM AE: 40 min cycling at 75% of HRmax |
female | mean 62.3 | RE, but not AE, ↑ DHEA immediately post-exercise. DHEA values returned to normal by 30 min post-exercise. |
Villareal, 2006 228 | Training | Whole body progressive RET: 2-3 sets, 6-12 reps at 65-85% 1RM for 4 months |
male and female | 65-78 | ↔ resting DHEA following 4 months of RET. |
Aldred, 2009 269 | Acute | AE: 50% of maximal treadmill workload for 30 min | male and female | 65-75 | ↔ DHEA or DHEA-S immediately post-exercise. |
Heaney, 2013 268 | Acute | AE: incremental submaximal walk test, terminated at 75% HRmax | male and female | 60-77 | DHEA was ↑ immediately post-exercise and was ↔ by 1 hr post-exercise. |
