ANSWERS TO COMMON FITNESS QUESTIONS

We all have fitness questions, whether we’re new to working out or have been at it for a while. Here are the answers to some common fitness questions.  How Often Should I Work Out?  Everyone should commit to working out a minimum of three days a week to see results. The American College of Sports Medicine recommends a minimum of 150 minutes of high-intensity cardio, 75 minutes of vigorous-intensity exercise or a combination of moderate and vigorous-intensity exercise per week.

EXERCISE: THE KEY TO A LONG LIFE

Do you want to live a long and healthy life? Be strong and agile as you age? Enjoy life into your 90s?  The key to a lengthy, prosperous life is exercise. No matter your age – whether you’re 16 or 65 – you should begin now with an exercise program or step up the one you already have. Studies have shown exercising on a regular basis is part of a healthier and more rewarding senior life. Staying active may affect how long you live and how energetic and vital you remain. Exercise provides a kind of health insurance.

THE KNOWLEDGE TO BUILD A BETTER BODY

Kevin Balcirak is not playing around when it comes to fitness and health.

For the past 20 years, Balcirak (pronounced Ball-sir-rack) has owned and operated Body Structure in Lexington. While a 5-second Google search will yield a long list of gyms in the Bluegrass, Body Structure among them, Balcirak’s concept is quite different from the rest.

Better understanding of the type of depression a person experiences couldi mprove the effectiveness of treatment choices and the management of depressive symptoms. Depression is typically diagnosed based on verbalized symptoms patients experience. This relates to the way the symptoms are assessed and the accuracy of patient reporting.


Conor Liston, M.D., a professor of neuroscience and psychiatry at Weill Cornell Medicine in New York, reports his research team, using brain scans, has identified four unique subtypes of clinical depression based on distinct patterns of abnormal brain connectivity. Their findings appear currently in Nature Medicine (December 2016).


“The four subtypes of depression that we discovered vary in terms of their clinical symptoms but, more importantly, they differ in their responses to treatment,” said Liston. For psychiatric care and treatment, using brain scans may assist mental health professionals in understanding the nature of a patient’s depression.


This collaborative study included 1,180 functional magnetic resonance imaging (fMRI) brain scans of patients with clinical depression and healthy controls from across the country. Researchers from Weill Cornell Medicine and seven other institutions analyzed the scans and identified biomarkers linked with depression by assigning statistical weights

CURRENT RESEARCH REVEALS FOUR DEPRESSION SUBTYPES

to abnormal brain connections. They then predicted the probability the abnormal connections belonged to a particular subtype versus another. The study showed distinct patterns of abnormal connectivity in the brain differentiated among the four subtypes and were linked with specific symptoms. Reduced connectivity in the brain region that regulates fear-related behavior and reappraisal of negative emotional stimuli, for example, was most severe in two of the four subtypes, which demonstrated increased anxiety. The researchers believe their findings may be useful for identifying patients most likely to benefit from targeted neuro-stimulation therapies. In the past, efforts to characterize depression by looking at groups of verbalized symptoms that tend to co-occur and then testing neurophysiological links have produced inconsistent results.
