Which peptides are studied in relation to delayed onset muscle soreness?
A research-supply review of peptide and related compounds examined in delayed onset muscle soreness (DOMS) models, including allicin, melatonin, magnesium, sodium pyruvate, and gut-axis interventions. Evidence is drawn f
Delayed onset muscle soreness (DOMS) is the muscle pain and tenderness that develops after unaccustomed eccentric exercise, typically peaking 24–72 hours post-exercise. In the research literature, the compounds most frequently studied in relation to DOMS are not classical peptides but rather small molecules and nutritional agents with antioxidant or anti-inflammatory mechanisms: allicin, melatonin, magnesium, sodium pyruvate, and purple grape-derived products, as well as gut-axis interventions (prebiotics, probiotics, and synbiotics) [1][2]. No peptide with a defined sequence, molecular formula, or molecular weight is specified in the available evidence for DOMS.
The work centres on oxidative stress and inflammatory pathways, particularly the modulation of reactive oxygen species (ROS) and the nuclear factor erythroid 2–related factor 2 (Nrf2) antioxidant response element, as well as gut–muscle axis signalling [1][2].
Research Studies
Allicin and oxidative stress markers in eccentric exercise
Allicin (diallyl thiosulfinate) is a sulfur-containing compound derived from garlic. A registered clinical trial (NCT07812688) is investigating the effects of allicin pretreatment on DOMS, muscle function, and oxidative stress following eccentric exercise [2]. The study is designed to measure changes in markers such as creatine kinase (CK), lactate dehydrogenase (LDH), and malondialdehyde (MDA), as well as subjective soreness ratings. The trial protocol does not specify a peptide sequence or molecular weight for allicin; its chemical formula is C6H10OS2 and molecular weight is 162.27 g/mol, though these identifiers are not provided in the evidence block and are included here only for context. The evidence does not report outcomes; it describes a planned investigation.
Melatonin and recovery in soccer players
A qualitative research synthesis of nutritional strategies for performance and recovery in soccer players examined melatonin as a multi-target supplement [1]. The review synthesised evidence regarding melatonin's efficacy on recovery outcomes, including DOMS, in soccer players. Melatonin is a hormone (N-acetyl-5-methoxytryptamine) with a molecular weight of 232.28 g/mol, but the evidence block does not provide these identifiers. The synthesis reported that melatonin may support recovery processes, but the specific effect on DOMS was not quantified in the available excerpt. The population studied was soccer players.
Magnesium and muscle function in soccer players
The same qualitative synthesis evaluated magnesium as a nutritional intervention for performance and recovery in soccer players [1]. Magnesium is a mineral, not a peptide, with an atomic weight of 24.305 u. The review synthesised evidence on magnesium's role in muscle function and recovery, including potential effects on DOMS. The evidence block does not provide specific outcome data or effect sizes. The population was soccer players.
Sodium pyruvate and metabolic recovery in soccer players
Sodium pyruvate (C3H3NaO3, molecular weight 110.04 g/mol) was included in the qualitative synthesis of nutritional strategies for soccer players [1]. The review examined its efficacy on performance and recovery outcomes, including DOMS. The evidence block does not report quantitative results or the specific mechanisms by which sodium pyruvate might affect DOMS. The population was soccer players.
Purple grape-derived products and oxidative stress in soccer players
Purple grape-derived products, which contain polyphenols such as resveratrol and anthocyanins, were assessed in the qualitative synthesis for their effects on performance and recovery in soccer players [1]. The review synthesised evidence regarding their impact on oxidative stress and recovery processes, including DOMS. The evidence block does not provide specific outcome measures or effect sizes. The population was soccer players.
Gut-axis interventions (prebiotics, probiotics, synbiotics) and recovery in soccer players
The qualitative synthesis also examined gut-axis interventions—prebiotics, probiotics, and synbiotics—for their effects on performance and recovery in soccer players [1]. These interventions are not peptides but are studied for their potential to modulate systemic inflammation and oxidative stress, which may influence DOMS. The evidence block does not report specific findings on DOMS for these interventions. The population was soccer players.
Allicin pretreatment and muscle function in DOMS
The registered trial NCT07812688 specifically investigates allicin pretreatment on muscle function following eccentric exercise [2]. The study protocol includes measures of muscle function, such as peak torque and range of motion, in addition to DOMS and oxidative stress markers. The evidence block does not provide results; the trial is ongoing or not yet reported. The population is not specified in the available excerpt.
Allicin and oxidative stress in DOMS
The same trial NCT07812688 includes oxidative stress as a primary outcome, measuring markers such as MDA, superoxide dismutase (SOD), and glutathione peroxidase (GPx) [2]. The evidence block does not report baseline or post-intervention values. The study is designed to test the hypothesis that allicin pretreatment reduces oxidative stress and DOMS following eccentric exercise. The population is not specified.
