Scientists have discovered a molecular “switch” that may explain why some people benefit from aerobic exercise and strength training, while others do not. Using both animal and human subjects, researchers discovered that a protein called C-Jun N-terminal kinase (JNK) helps to determine our response to exercise. If JNK is activated during exercise, it stimulates skeletal…

A review of data from 36 published studies concluded that regardless of mode (aerobic, resistance, or a combination of both), exercise is both a safe and effective method for improving quality of life in breast cancer patients. Supportive Care in Cancer, July 2018

A review of data concerning nearly 128,000 men and women showed that individuals who normally sit for six or more hours per day have a 19% higher risk of early death than those who sit fewer than three hours per day. Excessive sitting may also increase one’s risk for the following: some cancers; heart disease;…

In this study, researchers measured lower extremity performance in 18 collegiate pitchers before and after a simulated game. While researchers observed no change in jump squat performance following the 117-pitch session, the participants did experience a decline in their hip abduction and adduction strength that may have affected their pitching velocity. The research team concludes,…

Using information gathered from one-on-one interviews and focus groups, researchers report that chronic obstructive pulmonary disease (COPD) patients are more likely to be physically active if they have routine contact with their healthcare provider, support from their peers, and access to regular organized exercise sessions. Primary Care Respiratory Medicine, June 2018

In a study that involved 1,120 employees from ten businesses, researchers found that participants who received customized information to promote physical activity and reduce sitting time not only experienced improved health but they also reported greater job satisfaction and increased productivity. Ergonomics, June 2018

Falls are a leading cause of death and injury among seniors, especially those with chronic kidney disease (CKD). An analysis of data concerning 157,753 adults age 65 and over found that CKD patients who regularly exercised had a 32% reduced risk for experiencing a fall. Preventing Chronic Disease, June 2018

After reviewing survey data and death records from individuals in both England and Scotland, researchers report that walking speed may predict one’s risk for an early death. In particular, the research team observed that slow walkers are 20-24% more likely to suffer an early death from any cause than those who walk at either an…

Prolonged sitting at work can cause poor posture, low back pain, and increased risk for cardiovascular disease and diabetes. To combat the negative effects of long periods of sitting, the American Council on Exercise recommends the following: standing for a few minutes every hour; sitting on a gym ball for half an hour per day…

High-intensity interval training (HIIT) involves multiple short bursts of intense exercise and is known to offer many health benefits. In this study, researchers recruited 30 inactive men and women who had never tried HIIT before. Participants then completed both high-intensity and traditional moderate-intensity exercise programs and then rated each on a multi-point pleasure-displeasure scale. Despite…
