Research shows Heat therapy could boost mitochondrial function in muscles

A new study described as first of its kind in humanity, finds that long-term heat therapy may increase mitochondrial function in the muscles. The discovery could lead to new treatments for people with chronic illness or disease.

Mitochondria, the “energy centers” of the cells, are essential for maintaining good health. A decrease in the number or function of mitochondria may contribute to chronic and potentially serious conditions such as heart disease, chronic obstructive pulmonary disease and type 2 diabetes. Exercise has been shown to create new mitochondria and improve function of existing mitochondria. However, some people with chronic illnesses are not able to exercise long enough — previous research suggests close to two hours daily — to reap the benefits. Rodent studies have suggested that heat exposure may also induce the production of more mitochondria.



Researchers from Brigham Young University in Utah studied 20 adult volunteers who had not participated in regular exercise in the three months prior to the study. The research team applied two hours of shortwave diathermy — a type of heat therapy generated by electrical pulses — to the thigh muscles of one leg of each person every day. The researchers based the six-day trial of heat on the minimum amount of exercise needed to measure changes in muscle, or about two hours each day. They designed the treatment to mimic the effects of muscle heating that occurs during exercise. The therapy sessions increased the temperature of the heated leg by approximately 7 degrees F. Each participant’s other leg served as a control, receiving no heat therapy or temperature change. The researchers looked at mitochondria content in the muscles on the first day of therapy and 24 hours after the last treatment.

Mitochondrial function increased by an average of 28 percent in the heated legs after the heat treatment. The concentration of several mitochondrial proteins also increased in the heated legs, which suggests that “in addition to improving function, [repeated exposure to heat] increased mitochondrial content in human skeletal muscle,” the research team wrote.

“Our data provide evidence to support further research into the mechanisms of heat-induced mitochondrial adaptations,” the researchers explained. People who are not able to exercise for long periods of time due to their health may benefit from [heat] treatments.

Soft Drink after hot exercise endangers kidney.

Published

Downing a cool soft drink after a hot workout can feel refreshing. However, according to the latest research, it may cause further dehydration and interfere with kidney function.

Caffeinated soft drinks that are high in fructose are hugely popular worldwide. They need no introduction.



The beverages have been widely lambasted for their potential role in both the obesity and diabetes crises, and a recent study may add a fresh health risk to the growing list.

Researchers from the University at Buffalo in New York recently assessed soft drinks’ impact on kidney health when consumed during and after physical exertion.

When we exercise in a hot environment, blood that flows through the kidneys is reduced. This helps regulate blood pressure and conserve water. It is a normal response and causes no harm.

However, in clinical settings, a steep drop in blood flow through the kidneys can cause acute kidney injury (AKI) because of the accompanying drop in oxygen supply to the tissues.

Earlier studies have shown that exercise, in general, but particularly in higher temperatures, increases biomarkers of AKI.

At the same time, research also indicates that consuming a high-fructose soft drink increases AKI risk in rats experiencing dehydration.

Somalia empowers President to appoint foreigner as Central bank governor.

Published

on

Somali lawmakers voted on Monday to allow the president to appoint a foreigner as governor of the central bank of the volatile Horn of Africa nation.



Previously only a citizen could be appointed to the role as is the case across much of the continent. The vote was held in the lower house of the parliament.

An overwhelming majority of lawmakers (158) voted for the change as proposed by the government of President Mohamed Abdullahi Farmaajo and Prime Minister Ali Hassan Khayre.

Seventeen MPs kicked against the move even though the government justified the proposal by saying the country needed every available expertise to change its fortunes.

Even though there is no known foreign candidate for the role, a presidential assent – which is seen as procedural – will see government headhunt for a a new bank chief.
