Physical performance and regeneration after exercise is enhanced by the ingestion of proteins and carbohydrates. These nutrients are generally consumed by athletes via whey protein and glucose-based shakes. In this study, effects of protein and carbohydrate on skeletal muscle regeneration, given either by shake or by a meal, were compared. 35 subjects performed a 10 km run. After exercise, they ingested nothing (control), a protein/glucose shake (shake) or a combination of white bread and sour milk cheese (food) in a randomized cross over design. Serum glucose (n = 35), serum insulin (n = 35), serum creatine kinase (n = 15) and myoglobin (n = 15), hematologic parameters, cortisol (n = 35), inflammation markers (n = 27) and leg strength (n = 15) as a functional marker were measured. Insulin secretion was significantly stimulated by shake and food. In contrast, only shake resulted in an increase of blood glucose. Food resulted in a decrease of pro, and stimulation of anti-inflammatory serum markers. The exercise induced skeletal muscle damage, indicated by serum creatine kinase and myoglobin, and exercise induced loss of leg strength was decreased by shake and food. Our data indicate that uptake of protein and carbohydrate by shake or food reduces exercise induced skeletal muscle damage and has pro-regenerative effects.

Introdução: O exercício exaustivo agudo aumenta significativamente o consumo de oxigênio pelo organismo, aumentando a produção de Espécies Reativas de Oxigênio (EROs). Por serem moléculas altamente instáveis, as EROs podem causar danos oxidativos e induzir a morte celular. Para minimizar os efeitos deletérios das EROs o organismo possui sistemas de defesa antioxidante. O objetivo deste estudo foi testar o potencial antioxidante do Panax ginseng através da análise de marcadores de peroxidação lipídica, lesão muscular e capacidade antioxidante após um protocolo de exercício exaustivo agudo de natação realizado em ratos. Material e métodos: Foram utilizados 21 ratos Wistar machos divididos em: grupo controle–CO (n=7); grupo suplementado-exercitado–SG (n=7) e grupo não-suplementado-exercitado-NS (n=7). Foram coletados 10 mL de sangue total para obtenção de soro e posterior realização das análises: peroxidação lipídica (MDA), capacidade antioxidante total (CAT), ácido úrico, creatina quinase (CK), aspartato aminotransferase (AST) e alanina aminotransferase (ALT). Resultados: Observou-se maior concentração de MDA no grupo NS (0,60 ± 0,23μM) em relação aos grupos CO (0,18 ± 0,09 μM) e SG (0,26 ± 0,19 μM), p<0,05. Os níveis elevados de AST observados nos grupos SG (141± 24 U/L) e NS (199 ± 92 U/L) em relação ao CO (89 ± 27 U/L), p<0,05, indicam maior nível de lesão muscular nos grupos exercitados. Não houve diferenças estatísticas para ALT, CK, ácido úrico e CAT. Conclusão: A administração crônica de Panax ginseng favorece a proteção contra o excessivo ataque oxidativo muscular, que ocasiona peroxidação lipídica e eventual perda de função celular.Effects of Panax ginseng Supplementation upon Oxidative Stress and Skeletal Muscle Damage Biomarkers Induced by Acute Forced Exercise in RatsIntroduction: Exhaustive exercise increases significantly oxygen consumption by the organism, which leads to increase in Reactive Oxygen Species (ROS) generation. ROS are highly unstable and reactive molecules that can cause oxidative damage and even the cellular death. To minimize ROS deleterious effects, organism has antioxidant defense systems. The aim of this study was to test Panax Panax ginseng antioxidant capacity through lipid peroxidation, oxidative stress and muscle damage biomarkers after a swimming acute exhaustive exercise protocol in Wistar rats. Materials and methods: Twenty-one rats were divided in: control group–CO (n=7) that was not supplemented and did not realize exercise; Panax ginseng supplemented-exercised group–SG (n=7) that did exhaustive exercise and supplementation; not supplemented-exercised group–NS (n=7) that was not supplemented but did exercise. We collected 10mL of blood to obtain serum for biochemical analyzes: lipid peroxidation (MDA), total antioxidant capacity (CAT), uric acid, creatine kinase (CK), aspartate aminotrasferase (AST) and alanine aminotransferase (ALT). Results: There was an increase in MDA concentration in NS group (0.60 ± 0.23 μM) in comparison to CO (0.18 ± 0.09 μM) and SG (0.26 ± 0.19 μM); the higher AST levels on SG (141± 24 U/L) and NS (199 ± 92 U/L) in comparison to CO group (89 ± 27 U/L), indicating higher levels of muscle damage in both exercised groups. There were no statistical differences in CK, uric acid and ALT levels. Conclusion: We concluded that chronic Panax Panax ginseng supplementation can protect organism against increase in lipid peroxidation induced by exhaustive exercise.

ABSTRACT Polymethoxyflavones (PMFs) contained in the peel of citrus fruits have anti-inflammatory, anticancer, and antidepressant effects. However, their effects on skeletal muscle are unknown. We investigated whether PMFs could prevent skeletal muscle damage induced by eccentric exercise in rats. Downhill running for 90 min increased the levels of the inflammatory cytokines, monocyte chemotactic protein-1 (MCP-1), and interleukin-1β (IL-1β) in skeletal muscles, especially in vastus lateralis, and the plasma creatine kinase levels. These increases were attenuated by a single oral administration of orange peel extract (OPE) 30 min before downhill running. A mixture of nobiletin, sinensetin, 3,5,6,7,8,3′,4′-heptamethoxyflavone, and tangeretin, which are the major PMFs of OPE, also showed similar effects on muscle damage. These results suggest that OPE has a protective effect against eccentric exercise-induced skeletal muscle damage, and that the effects may be attributed to the 4 major PMFs.
