Exercise and food restriction in rats

Article Abstract:

The effect of exercise and food restriction on longevity in mice was evaluated. Results showed that although exercised mice survived longer, longevity did not increase considerably. On the other hand, diet restriction promoted a longer life span in mice. A combination of exercise and diet restriction increased mortality before 900 days of age in mice. However, the maximal longevity is comparable to that of diet-restricted mice. The enhanced longevity resulting from diet restriction can be attributed to the decrease in metabolism leading to a reduction in toxins, carcinogens and metabolic waste accretion.

Exercise and iron status

Article Abstract:

Exercise leads to increased iron loss. The average daily iron loss of 1.4 mg increases to 1.75 mg in men and 2.3 mg in women undergoing training. Iron loss due to increased intravascular hemolysis depletes the body's iron reserves which may lead to anemia. Athletes in training need to take dietary iron supplements to augment losses incurred and prevent deleterious consequences of iron deficiency such as poor athletic performance, depression of immune response and reduced thermoregulating functions.

Carbohydrate supplementation during exercise

Article Abstract:

Skeletal muscle oxidizes glucose to fuel its activities. With longer exercise periods, muscle becomes increasingly dependent on blood glucose for its energy requirement. This in turn reduces blood glucose concentration, leading to a state of hypoglycemia which causes fatigue. Fatigue results from energy deprivation and incomplete carbohydrate oxidation. Maintaining blood glucose level above hypoglycemic level through carbohydrate supplementation during exercise delays fatigue by 30 to 60 minutes.
