The Claim
In endurance-trained male runners aged 39–58 years, acute supplementation with vitamin C and E has no significant effect on the recovery of countermovement jump height and squat jump height following a bout of prolonged running.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking vitamin C and E supplements right after long-distance running does not change how high healthy male runners can jump during recovery.
See the scientific wording
In endurance-trained male runners aged 39–58 years, acute vitamin C and E supplementation does not significantly affect performance recovery, including countermovement jump and squat jump height, after a bout of prolonged running, suggesting that antioxidant intake does not enhance neuromuscular function restoration.
After long-distance running, muscle cells experience stress that temporarily reduces their ability to generate force quickly. Taking vitamin C and E does not change how the muscles recover their strength or how the nerves signal them to contract. The muscles and nerves return to normal function at the same rate whether or not these vitamins are taken.
What the research says
1 studyThe study gave some runners vitamin C and E before a long run and others a placebo, then checked how well they could jump afterward. Both groups recovered the same way—so the vitamins didn’t help them bounce back faster.
