A recent study examined the effects of very-high intensity exercise using short rest periods on a number of markers for muscle damage among highly-trained males and females. Eighteen participants (9 men and 9 women) engaged in a descending pyramid scheme starting at 10 repetitions, decreasing 1 repetition per set for the back squat, bench press, and deadlift, as fast as possible.

A variety of recent investigations have examined the potential for using video games that require physical effort to play as seen with Nintendo Wii, Nintendo Wii U, PlayStation Move and Xbox Kinect titles. Active or interactive games have been shown to provide a number of positive outcomes when implemented a regular structured activity or simply as a supplement to a weightlifting and aerobic conditioning program.
The lat pull-down is a popular exercise which is primarily useful for improving open-chain strength in the latissimus dorsi, rhomboids and biceps. Many grips and pulling angle variations can be employed to vary the activation of upper back musculature as well as the assistive force provided by the biceps and forearms. As it relates to grip use during this lift, anecdotal reports suggest that a wider grip promotes enhanced activation of the latissimus dorsi and greater improvements in strength when compared with a narrow grip.
Glucosamine is widely-used to treat arthritis and prevent joint degeneration. Interestingly, it is also understood to reduce the rate of cancer cell growth as well as the metabolism of ingested sugars. In 2007, a study led by medical researcher Michael Ristow showed that excess nutritive sugar shortens the lifespan of roundworms, a widely-studied model organism in ageing research. Unfortunately, the method used was ineffective among rodents; limiting further research at that time. Currently, in a recent study published in the journal Nature Communications (2014), Ristow and his colleagues have now applied glucosamine to roundworms and found that they lived ~5% longer than their untreated counterparts. After this initial step, the team fed glucosamine to ageing mice (100 weeks of age, equal to about 65 years old among humans) in addition to their normal diet. The supplement appeared to extend their lifespan by ~10%; reflecting around 8 additional years of human lifespan (compared to control mice). Moreover, the glucosamine improved glucose metabolism among the elderly mice.
The Personal Trainers to Watch program recognizes elite trainers from around the world. Nominations will be collected throughout the month of July, and the top 10 finalists will compete in a live global competition this fall to determine the winner. Any stakeholder including clients, personal trainers and gym owners, can visit www.lifefitness.com/personaltrainers between July 1 and July 31, 2014, to nominate a personal trainer who supports a powerful vision, exemplary commitment to enhancing client experiences and pursues continuing education for mastery of the profession. Nominees will also be judged on leadership, client motivation, inspiration and previous recognitions. Ten finalists will be invited for a final round of judging where they will be immersed in popular training techniques incorporating the Life Fitness Synrgy360, a state-of-the-art functional training system.
The proposed benefits of barefoot running have made it an increasingly-popular topic both in scientific research as well as lay media. Supporters suggest that these benefits include a potential for reduced injury risk as well as improved performance. Despite the recent attention by scientists and runners alike, there remains little conclusive evidence proving or refuting these proposed advantages. According to a recent review published in the British Journal of Sports Medicine, this lack of irrefutable evidence is the result of a number of factors ranging from the overall complexity of running injuries to improper analysis of data. The authors of this review aimed to evaluate and address driving factors behind current research on the effectiveness of barefoot running as a means to reduce injury risk and improve performance.
Combining genes from different organisms is known as recombinant DNA technology, and the subsequent organism is said to be “genetically modified (GM)”. The first GM food approved by the Food and Drug Administration for marketing in the USA in 1994 was the “Flavour Saver Tomato”, with genetic modification allowing the tomato to delay ripening after picking. As of 2011, the USA leads a list of multiple countries in the production of GM crops; some of the most popular being corn, soybeans and canola, all of which are staple ingredients in virtually every type of packaged food. GM foods, or genetically modified organisms (GMO), seem to offer advantages and disadvantages with respect to its safety.
