Effect of nocturnal exhaustion exercise on the metabolism of selected elements

Abstract

The present study aims to examine how exercise performed until fatigue at night affects element distribution in the serum. The study examined 10 healthy sedentary males who were not actively engaged in any particular sport and whose mean age was 23.00±0.25 years, mean height 177.79±2.25 cm, and mean weight 70.70±1.63 kg. Blood samples were collected from the subjects at midnight twice: during rest before exercise and after exercise. Serum phosphorus, sodium, potassium, sulfur (mmol/L), cobalt, boron, cadmium, chrome, nickel, manganese, molybdenum, copper, iron, zinc and calcium levels (mg/L) were measured using atomic emission spectroscopy (ICP-AES). Exhaustion exercise performed at night brought about a decrease in copper levels only (p<0.05), while elevating levels of potassium, sodium, magnesium, calcium, iron, zinc, manganese, nickel, selenium, molybdenum, chrome, cobalt, lead and cadmium (p<0.05). The results of the study demonstrate that nighttime exercise until exhaustion significantly alters element metabolism.
