Teenagers who increased daily exercise to at least 20 minutes were able to cut back on their smoking habit. The study found that this short walk helped teens resist lighting up a cigarette and increase their chances of quitting altogether.
A study of 126 inactive older adults with cognitive complaints found significant improvement in cognitive function after 12 weeks of physical and mental activity. However, there was no difference between the intervention and control groups, suggesting that the amount of activity may be more important than its type.
Researchers confirm that obesity leads to a decrease in physical activity over time, with obese participants showing an 8% drop in moderate to vigorous activity. The study uses objective measurement methods and large sample size to provide insight into the relationship between inactivity and weight gain.

Researchers found that exercise-loving mice have significantly greater midbrain volume and larger non-cerebellar brain mass compared to regular mice. The study supports the mosaic theory of brain evolution, suggesting that changes in brain size may be region-specific rather than overall.
A systematic review of four studies suggests that acupuncture may have a positive effect on exercise performance and recovery after exercise. However, additional trials with larger sample sizes and randomized designs are required to confirm these findings.
A new study found that only 39% of four-year colleges and universities require physical education, compared to 97% in the 1920s. Research shows that exercise improves cognitive performance and reduces obesity, but institutions are not embracing their own research.
Researchers discovered a key protein receptor plays a crucial role in motivation during physical exercise, explaining why many people struggle to stick to their fitness goals. The CB1 cannabinoid receptor regulates the brain's reward system, controlling how long individuals engage in voluntary physical activity.
In a large randomized trial, aerobic training was shown to result in greater weight and fat loss compared to resistance training or a combination of both. Aerobic exercise also led to significant reductions in waist circumference and improvements in cardiopulmonary fitness.
Researchers found that six weeks of resistance training significantly improved blood markers of cardiovascular health in young African-American men, but not Caucasian men. This suggests that resistance exercise training is more beneficial in young African-American men.
Asthmatic children in NYC asthma hotspots experience more frequent exercise-induced wheeze and ER visits than those in lower-asthma areas. Parents and physicians should be aware of the need for medication, such as bronchodilator inhalers, before exercise.
A recent study found that nearly 40% of African-American women avoid exercise due to their hair. Hair care and hairstyle maintenance can be costly and lead to sweating, which may deter women from engaging in physical activity. Women with normal scalps were more likely to participate in aerobic exercises.
A study by Wake Forest Baptist Medical Center reveals that hair care complications are a primary factor deterring African-American women from exercising. The research found that over 40% of respondents reported avoiding exercise due to hair-related issues, with many using heat straighteners or chemical products to style their hair.
Researchers found that aerobic exercise led to greater weight and fat loss compared to resistance training, which only increased lean body mass. The combination of both exercises showed mixed results but provided a significant decrease in waist circumference.
Aerobic exercise has been shown to improve cognitive function in older adults, including task switching, selective attention, and working memory. The evidence suggests that regular physical activity can attenuate age-related decline in these areas, providing a simple means for people to optimize their brain power.
Research found that healthcare providers often advise overweight and obese women to gain less weight than recommended, leading to potential health risks. Women also received limited exercise guidance, with most advised to limit or stop exercising altogether.
Scientists at Dana-Farber Cancer Institute have isolated a previously unknown protein in muscles that spurs their growth and increased power following resistance exercise. The protein, PGC-1 alpha-4, controls the activity of two molecular pathways involved in muscle growth.
New research at the University of Missouri suggests that eating fewer, larger meals can be more beneficial for obese women than consuming small meals throughout the day. The study found that this approach lowered blood-fat levels and reduced the risk of developing heart disease.
A recent study found that exercise in horses reduced embryo recovery rates and quality, potentially impacting early embryonic development. The research also suggests a possible link between intense exercise and detrimental effects on female reproductive blood flow, highlighting the need for further studies.

Participants who received personalized feedback and set health goals reported increased physical activity compared to those who did not receive the intervention.
Researchers advise limiting daily vigorous exercise to 30-50 minutes due to potential harm from excessive intensity. A balanced routine of moderate physical activity can add years to life, while marathon-like activities may speed progress towards the finish line.
A short burst of moderate exercise enhances memory consolidation in healthy older adults and those with mild cognitive impairment. Exercise immediately after viewing pleasant images improved recall in both groups compared to those who did not exercise.
A Kansas State University study found that exercising with a teammate perceived as better increases workout time and intensity, but only when the partner is approximately 40% more skilled. Over time, this motivation can lead to significantly longer exercise sessions.
A study found that exercise programs on stationary bicycles improve Parkinson's disease symptoms, with faster pedaling leading to greater brain connectivity and motor ability improvements. The therapy is low-cost and effective, even for patients who don't need forced-rate exercise.
A recent study found that exercise can alleviate high blood pressure in pregnant rats by restoring balance between vascular growth factors. Exercise also improved endothelial cell function and reduced oxidative stress without compromising fetal weight.
Aerobic exercise can help relieve fatigue associated with cancer and treatment, balancing rest with physical activity may reduce fatigue.
