A field study was performed to investigate the acute influence of a milk protein hydrolysate supplemented drink (CHO+PRO) on metabolism during and after a marathon run compared to the same drink without protein (CHO). Carbohydrate metabolites and hormones were not influenced by CHO+PRO. Levels of plasma free fatty acids were significantly lower and levels of urea and most amino acids were significantly higher with CHO+PRO. Sweat urea and ammonia nitrogen excretion during the run as well as… 
Metabolic response to provision of mixed protein-carbohydrate supplementation during endurance exercise.
TLDR
Modified nutritional supplementation in this study altered the endocrine response as well as substrate availability and utilization following and during an endurance run, respectively.
Muscle metabolism during exercise with carbohydrate or protein-carbohydrate ingestion.
TLDR
When trained men ingest CHO at a rate on the upper end of the range generally recommended to improve endurance performance, coingestion of PRO does not alter specific markers proposed to reflect an enhanced capacity for skeletal muscle energy delivery.
Combined carbohydrate–protein supplementation improves competitive endurance exercise performance in the heat
TLDR
CHO–PRO supplementation appears to prevent body mass loss, enhance thermoregulatory capacity and improve competitive exercise performance despite no effect on muscle damage.
Glutamine and carbohydrate supplements reduce ammonemia increase during endurance field exercise.
Blood ammonia concentration increases during endurance exercise and has been proposed as a cause for both peripheral and central fatigue. We examined the impact of glutamine and (or) carbohydrate
INFLUENCE OF INGESTING CASEIN PROTEIN AND WHEY PROTEIN CARBOHYDRATE BEVERAGES ON RECOVERY AND PERFORMANCE OF AN ENDURANCE CYCLING TEST
TLDR
TheCHO+Pw and CHO+Pc drinks could be recommended for improving recuperation from intensive exercise and one purported mechanism indicates muscle glycogen re-synthesis is enhanced when protein is added to a CHO recovery formula.
Effects of a carbohydrate and a carbohydrate and casein protein beverages on recovery and performance of endurance cycling capacity.
TLDR
Within the context of this experimental design, the CHO+P drink showed different physiological effects than the CHO drink, so that the CHO-P drink can be recommended for improving recuperation from intensive exercise.
Coingestion of carbohydrate-protein during endurance exercise: influence on performance and recovery.

TLDR
This review examines the existing research regarding the efficacy of carbohydrate-protein consumption during endurance exercise and suggests that the importance of protein for endurance athletes has been underappreciated.
Effects of Ingesting Protein in Combination With Carbohydrate During Exercise on Endurance Performance: A Systematic Review With Meta-Analysis
TLDR
Compared to carbohydrate alone, coingestion of protein and carbohydrate during exercise demonstrated an ergogenic effect on endurance performance when assessed by time to exhaustion and also where supplements were matched for carbohydrate (isocarbohydrate).
CONSUMPTION OF AN ORAL CARBOHYDRATE‐PROTEIN GEL IMPROVES CYCLING ENDURANCE AND PREVENTS POSTEXERCISE MUSCLE DAMAGE
TLDR
To prolong endurance performance and prevent increases in muscle damage, it is recommended that male and female cyclists consume CHO+P gels rather than CHO gels during and immediately following exercise.
Effects of high-fat and high-carbohydrate diets on metabolism and performance in cycling.
TLDR
High-fat dietary conditioning increased fat oxidation, and although the main effects were not statistically significant, there was some evidence for enhanced ultra-endurance cycling performance relative to high-carbohydrate.
