Research can provide golden insights for health and fitness professionals. Here are some recent findings to help you stay ahead of the curve:
High-Intensity Interval Training Improves Memory in Older Adults
📚 Read the study
Twelve weeks of high-intensity interval training performed three times per week leads to greater improvements in memory than moderate-intensity continuous training in older adults. Given the relatively inexpensive nature of exercise as a therapeutic intervention, high-intensity interval training may be an effective strategy to counteract age-related declines in memory.
Note: Just like memory, high-intensity interval training also leads to greater improvements in body composition. Learn why cardio can make you fat in the long run if it’s not done at the right intensity.
How Length Sizes Affect Body Composition Estimation in Adolescent Athletes Using Bioelectrical Impedance
📚 Read the study
Longer length sizes—and especially longer lower limbs—result in overestimation of lean body mass with BIA (bioelectrical impedance). The accuracy of BIA measurements may decrease in athletes with length dimensions and body proportions significantly different than that of the general population.
Note: This is yet another reason why you shouldn’t use bioelectrical impedance to measure body fat. A DEXA scan or skinfold measurements are much more accurate options.
Prolonged Static Stretching Causes Acute, Nonmetabolic Fatigue and Impairs Exercise Tolerance During Severe-Intensity Cycling
📚 Read the study
Stretching reduced maximal force and augmented muscle activation, which in turn increased the metabolic response to sustain exercise.
Note: We’ve known for years that static stretching makes you weak. Now add fatigue and impaired exercise tolerance to the list. If you still do static stretching religiously as part of your warm-up, it may be time to rethink your routine!
