The Claim
In healthy young adult males walking at 5 km/h, heart rate increases linearly with increasing vest load mass, demonstrating a proportional relationship between carried weight and cardiovascular demand.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When healthy young men walk at 5 km/h while wearing weighted vests, their heart rate rises steadily with each additional kilogram of weight.
See the scientific wording
In healthy young adult males, heart rate increases linearly with vest load mass during walking at 5 km/h, indicating a proportional cardiovascular demand that escalates predictably with each additional kilogram of carried weight.
When a person walks while carrying extra weight, their body needs more oxygen to keep moving. The heart beats faster in direct proportion to how much extra weight is carried, because the body must deliver more oxygen to the muscles with each beat. This happens even though the total energy needed goes up faster than the heart rate, meaning the heart compensates by beating more often rather than harder.
What the research says
1 studyWhen people walk with a weighted vest at a steady pace, their heart beats faster—and for every extra kilogram they carry, their heart rate goes up by a consistent, predictable amount. This study proved that exact pattern.
