How Blood Pressure Affects Heart Health Throughout Your Life

Blood pressure readings from age 36 onwards predict heart blood flow at 77, regardless of current levels. The MyoFit46 study, which tracked 459 people across four decades, revealed that midlife pressure between 120-140 mmHg causes the steepest decline in heart perfusion. Each 1% reduction in blood flow is associated with a 3% higher risk of major cardiac events.

What Astronauts Teach Us About Why Your Body Needs Resistance to Stay Healthy

Space travel highlights the importance of resistance training for maintaining good health. In weeks without gravity, astronauts face cardiovascular decline, bone loss and muscle atrophy. These changes resemble sedentary life on Earth. Crews train 2.5 hours daily, yet still deteriorate. Microgravity research suggests that resistance training can substitute for the natural challenges that evolution has built into human function.

Skill-Related Components of Fitness

The skill-related components of fitness—agility, balance, coordination, power, reaction time, and speed—are the foundation of movement quality. These six key elements enhance physical performance in sports and daily life. They enable efficient, controlled movement patterns, improving strength, precision, and overall athletic ability across various activities.

Skinfold Measurement Body Fat Accuracy

Skinfold measurement body fat testing uses callipers to estimate body composition by measuring subcutaneous fat at key sites. Accuracy is reasonable (±3.5% error) when trained technicians use quality equipment. Correlations with gold-standard methods range from 0.70 to 0.93. Accuracy depends on several factors, including technician skill, environment, equations, and repeated measures to reduce variability.
