Is Aerobic Exercise a Useful Treatment for Concussion?
Newswise — Until recently, advice for patients who sustained a concussion might have been to avoid all physical activity until symptoms went away. However, this approach seems to harm patients more than help them. With this knowledge, health care professionals now encourage physical activity after injury. Currently, aerobic exercise that does not make symptoms worse has become a popular treatment for concussion.
In this review article, the study authors examined existing evidence on aerobic exercise as a concussion treatment. Approximately 34 published scientific studies were examined on this topic. They found that most existing research indicates aerobic exercise is a useful way to reduce symptoms after injury, particularly for patients who continue to experience symptoms for several months. Key areas for future research in this area include better definitions for the timing of when to begin, the intensity, the frequency, and the duration of exercise after a concussion.

Evening or Morning Aerobic Training: Which is Better to Treat High Blood Pressure?
Many people have high blood pressure–approximately one billion people worldwide. Besides taking medications, people with this health problem are advised to do aerobic training (walking, running, cycling or swimming at moderate intensity) to reduce blood pressure. For a long time, scientists have considered what is the best time of day to train in order to get health benefits.
In this study, scientists studied whether training in the morning or evening produces different reductions in blood pressure in men being treated with medications for hypertension. In all, 50 hypertensive men being treated by medications participated. Investigators compared their blood pressures before and after 10 weeks of exercise training. Subjects were randomly assigned to one of three groups: one that trained in moderate-intensity cycling for 45 minutes between 7 and 9 a.m.; another group trained the same way for 45 minutes between 6 and 8 p.m.; and a third group only did 30 minutes of stretching in the morning or evening. The results showed that only training in the evening reduced blood pressure meaningfully over the 10 weeks. However, training in the morning also produced cardiovascular benefits. Therefore, training at both times of day may be recommended for hypertensives, but to achieve greater and faster blood pressure reductions evening aerobic training may be preferred.
