Active Voice: How does Exercise Improve Immune Bioenergetics?
By Jong-Shyan Wang, Ph.D. |
 |
|
Natural killer (NK) cells, which are found in the blood, are crucial in the prevention and treatment of cancer. They function by eliminating malignant tumors in an innate immune manner. NK cells express an array of activating and inhibitory receptors that recognize cancer cells without the need for immunization. Cytotoxicity is a process that results in damaging or destroying cells. The antitumor cytotoxicity of NK cells depends on their ability to recognize cancer cells and the production of cytotoxic proteins. Mitochondrial bioenergetics is essential for optimizing NK cell effector functions, including increased cytotoxic potential and cytokine production.
Regular exercise reduces mortality associated with most cancers. An acute bout of exercise mobilizes NK cells that enter the bloodstream from peripheral tissues. They can modulate the antitumor cytotoxicity of NK cells by altering cellular protein contents in an intensity-dependent manner. However, patients with malignancies experience gradual declines in muscle strength and cardiorespiratory fitness which can influence their ability to exercise. This may lead to a more sedentary lifestyle. High-intensity interval training (HIIT) has been shown to be a more effective modality for improving cardiorespiratory fitness than moderate-intensity continuous training in both healthy individuals and patients with cardiovascular disease.

Policy Corner: Help Pass the PHIT Act
|
 |
|
Too often today, programs are designed to deal with illnesses rather than prevent them. Under current law, Americans predominantly use pre-tax accounts to pay for treatment and detection of illnesses, prescription drugs, doctor visits, examinations and screenings. This type of program ignores the importance of prevention for a healthy lifestyle.
One of ACSM’s advocacy goals is to pass the Personal Health Investment Today (PHIT) Act. As introduced, the PHIT Act would change the types of expenditures that could be payable out of tax-favored health savings accounts (HSAs), flexible spending accounts (FSAs), medical savings accounts (MSAs) and/or medical reimbursement arrangements. The PHIT Act would allow consumers to include prevention in the form of increased physical activity, allowing fitness center dues, payments for some exercise equipment, youth sports/physical activity fees and other costs associated with active lifestyles to be paid with pre-tax dollars — up to a $1,000 cap for individuals and $2,000 for families.
The PHIT Act gives consumers the option of using their pre-tax medical funds for physical activity to prevent illness and to live a healthy lifestyle. Please contact your members of Congress and ask them to co-sponsor and support the PHIT Act.
Thank you in advance for taking this step in the interest of better health and fitness for all Americans. If you have any questions, please contact us at mward@acsm.org.

Students Honored with Outgoing Editor-in-Chief Scholarship

ACSM continues its outgoing editor-in-chief (EIC) recognition scholarship program by awarding a scholarship totaling $1,000 in honor of Roger M. Enoka, Ph.D. Dr. Enoka will complete his second term as the EIC of Exercise and Sport Sciences Reviews (ESSR) at the end of 2022.
The purpose of the program is to recognize and continue the outstanding legacy of our journals’ EICs by investing in the future of the field. Dr. Enoka selected two doctoral students, Taylor Tvrdy and Sajjad Daneshgar, to receive the scholarship. As with many of us, these two students encountered some difficult challenges during the COVID-19 pandemic and are grateful for the additional support provided by the scholarship.
Dr. Enoka served as the interim EIC for ESSR throughout 2013, was selected to serve as the next EIC in 2014 and then undertook a second term beginning in 2018. Check out the January 2022 issue editorial for more about the history of ESSR, in its 50th volume year, and Dr. Enoka’s career-spanning support of this historic publication.
The EIC recognition scholarship program began in 2013 with outgoing EIC Andrew J. Young, Ph.D., FACSM (Medicine & Science in Sports & Exercise®) and the late Priscilla M. Clarkson, Ph.D., FACSM (ESSR).
