A golf-swing training device for improving ball-driving distance and accuracy. The training device mounts to a golf club and signals to the golfer when the club head begins decelerating in the direction of the forward motion of a golf swing. Additional energy is available for transfer from the club head to the ball as the club head is transitioning from acceleration to deceleration.

Inorganic anions nitrate and nitrite influence metabolic rate and glucose homeostasis. Infusion of nitrite iv caused an acute drop in resting energy expenditure (oxygen consumption) and nitrate, when given perorally, caused a reduction in oxygen consumption during exercise and a depression of the increase in blood glucose observed after an oral glucose tolerance test. The doses of nitrate and nitrite did not cause any detectable change in methemoglobin levels of blood. Also, nitrate and nitrite did not alter lactate levels in blood. This discovery provides useful treatments to regulate the energy expenditure and glucose homeostasis of a mammal by administration of inorganic nitrite and / or nitrate.
