Regional differences in hamstring muscle damage after a marathon

Minimal muscle damage after a marathon and no influence of beetroot juice on inflammation and recovery.

This study examined whether beetroot juice (BTJ) would attenuate inflammation and muscle damage following a marathon. Using a double blind, independent group design, 34 runners (each having completed ca. ∼16 previous marathons) consumed either BTJ or an isocaloric placebo (PLA) for 3 days following a marathon. Maximal isometric voluntary contractions (MIVC), countermovement jumps (CMJ), muscle ...

hamstring muscle injuries, a rehabilitation protocol purpose

context hamstring acute muscle injuries are prevalent in several sports including afl football (australian football league), sprinting and soccer, and are often associated with prolonged time away from sport. evidence acquisition in response to this, research into prevention and management of hamstring injury has increased, but epidemiological data shows no decline in injury and re-injury rates...

Impaired muscle glycogen resynthesis after a marathon is not caused by decreased muscle GLUT-4 content.

Our purpose was to investigate whether the slow rate of muscle glycogen resynthesis after a competitive marathon is associated with a decrease in the total muscle content of the muscle glucose transporter (GLUT-4). Seven well-trained marathon runners participated in the study, and muscle biopsies were obtained from the lateral head of the gastrocnemius muscle before, immediately after, and 1, 2...

Running Pace Decrease during a Marathon Is Positively Related to Blood Markers of Muscle Damage

BACKGROUND Completing a marathon is one of the most challenging sports activities, yet the source of running fatigue during this event is not completely understood. The aim of this investigation was to determine the cause(s) of running fatigue during a marathon in warm weather. METHODOLOGY/PRINCIPAL FINDINGS We recruited 40 amateur runners (34 men and 6 women) for the study. Before the race, ...
