Incidents are trending downward over ten years.
OSHA has recorded 22 severe cases involving running and physical exertion, with an average of 3 incidents reported annually. These events frequently result in traumatic injuries, including fractures and serious soft tissue damage, which often require immediate hospitalization.
The impact of these injuries is significant, with body systems affected in 38 percent of all reported cases. Workers often face long-term health consequences, including cardiovascular strain and internal injuries that stem from intense physical demand.
Over the last decade, reported incidents have decreased by 33 percent, reflecting a shift in how physical tasks are managed. Despite this decline, the inherent risks of sudden bodily motion remain, particularly when employees are required to perform strenuous activities without adequate preparation.
Public administration leads all sectors, accounting for 50 percent of these severe cases, largely due to the physical fitness requirements inherent in those roles. Other industries, including manufacturing and health care, also see these injuries when workers are forced to move quickly or exert themselves under pressure.
Top causes based on OSHA incident reports
These injuries occur when the body is pushed beyond its limits during routine or emergency tasks. Whether it is a worker chasing a runaway object or an employee undergoing a mandatory physical fitness test, the source of injury is almost always the worker's own motion or position. Sudden changes in direction or high-intensity exertion can lead to immediate physical failure, such as muscle tears, bone fractures, or cardiovascular distress.

Employers are responsible for maintaining a safe environment, even during physical training or high-exertion tasks. Under the General Duty Clause of the Occupational Safety and Health Act, employers must provide a workplace free from recognized hazards that are likely to cause death or serious physical harm. When fitness testing or physical labor requirements lead to severe injury, an employer may be held accountable for failing to implement proper screening, training, or safety protocols.
Where these injuries occur most frequently
Public administration accounts for half of all reported cases, primarily because these roles often mandate rigorous physical fitness standards. When employees are required to run or perform high-intensity physical tests as a condition of their employment, the risk of injury increases significantly if the employer does not provide adequate medical oversight.
Employers in high-risk sectors must adhere to safety standards that protect workers during physical activity. This includes following guidelines under 29 CFR 1904.39 for reporting severe injuries and ensuring that any physical training programs are designed to minimize the risk of cardiovascular or musculoskeletal trauma. Failure to provide proper warm-up periods or medical monitoring during strenuous testing may constitute a violation of safety expectations.
From actual OSHA investigation files
Reported incidents reveal a clear pattern of injury occurring during mandatory fitness testing, emergency response training, or sudden physical reactions to workplace hazards. Many workers suffer severe health events, such as rhabdomyolysis or cardiac distress, while others sustain acute fractures or disc herniations when changing direction or chasing equipment. These stories highlight the danger of physical exertion when the body is not properly prepared or when the environment creates an unexpected demand for speed.
"An employee was training and running and suffered rhabdomyolysis."
"An employee was completing a physical fitness test and experienced shortness of breath, nausea, and a headache after 1 mile of a 1.5-mile run. She was hospitalized."
"An employee was detecting the lower explosive limit (LEL) and initiated a shutdown of the loading rack, stopping the flow to the rail car. The employee's personal four-gas monitor began to alarm for LEL and he evacuated north toward the end of the loading rack. The employee had difficulty catching his breath and had a rapid heart rate after he evacuated the area. The employee was hospitalized for atrial fibrillation."
"An employee was pushing a cart outside a building to get an oil container when a piece of foam blew off the cart. He was chasing after the foam when he heard a loud pop in his right leg and fell to the grass. The employee suffered a fracture to his right inferior femur."
"A football player was running a route during football practice. Upon cutting and changing direction, they felt pain in their lower back. The employee was hospitalized with a herniated disc in their lumbar region."
"An employee was completing a 1.5-mile run when they were hospitalized for weakness and mobility difficulties."
"An employee was participating in training. As they were jogging, they sustained a muscle injury."
"On May 14, 2022, an employee was strapping their truck and a beam started to fall down. The employee turned and started to run away and injured his quadriceps. He was hospitalized with a muscular injury to the left leg."
"An employee had chest pain after chasing a patient who was attempting to leave the unit."
"On February 7, 2020, an employee collapsed while running during training due to dehydration, resulting in acute kidney damage and hospitalization."
