The Claim
In untrained adults, the rate of phosphocreatine recovery following exercise is correlated with end-exercise intracellular pH levels in the quadriceps, finger flexors, and plantar flexors, with stronger correlations observed in the finger flexors.
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.
In people who do not regularly exercise, how quickly phosphocreatine returns to normal after exercise is linked to how acidic the muscle cells are at the end of exercise, and this link is stronger in the finger muscles than in the leg muscles.
See the scientific wording
In untrained adults, phosphocreatine recovery kinetics are correlated with end-exercise intracellular pH in the quadriceps, finger flexors, and plantar flexors, with stronger associations observed in the finger flexors, suggesting muscle-specific differences in how acidosis affects mitochondrial respiration.
When muscles work hard, they produce acid, which slows down the energy recovery system in the mitochondria. The more acidic the muscle gets during exercise, the slower it recovers its energy stores. This effect is strongest in the finger muscles because they are less able to remove acid quickly, making their energy system more sensitive to the acid buildup.
What the research says
1 studyIn people who don’t exercise much, the faster their muscles bounce back after working hard, the less acidic they got during the workout—and this connection is strongest in the finger muscles, weaker in the legs. The study measured this directly and found it to be true.
