How Many Calories Does Swimming Burn?

A 155-pound person burns about 204 calories in 30 minutes and approximately 408 calories in one hour of swimming. The activity has a MET value of about 5.8. Calories increase with body weight, duration, and intensity.

The number of calories burned while swimming is influenced by factors such as METs, body weight, duration, and intensity. Understanding these elements can help individuals estimate their caloric expenditure during swimming sessions.

Calories Burned From Swimming by Weight and Time

The following table provides a breakdown of calories burned by different body weights and durations of swimming.

Body weight	15 min	30 min	45 min	60 min
125 lb (57 kg)	82	164	247	329
155 lb (70 kg)	102	204	306	408
185 lb (84 kg)	122	243	365	487
215 lb (98 kg)	141	283	424	566

A heavier body and a longer session both burn more. Intensity matters too: the values above use 5.8 METs (freestyle laps, moderate).

Calories by Intensity

How hard you go changes the burn. The table below shows the MET value for each intensity and the calories a 155-pound person burns in 30 minutes.

Intensity	METs	Calories (30 min, 155 lb)
Backstroke	4.8	169
Leisurely	6.0	211
Breaststroke	5.3	186
Freestyle, vigorous	9.8	345

Tracking Exercise and Food in Nutrola

Calories burned only change your results if you record them. Nutrola lets you log a session like swimming in a few ways: describe it in your own words by voice or text, pick an exercise type and intensity, or enter the calories directly, and on iOS and Android it can sync workouts automatically from Apple Health or Health Connect. Logged workouts sit next to the food you track from a photo, barcode, or voice entry, so calories in and calories out stay in one place. Nutrola is available from EUR 2.50 per month and shows no ads on any tier.

Sources and Method

MET (metabolic equivalent) values are from the 2011 Compendium of Physical Activities (Ainsworth et al.), the standard reference for the energy cost of physical activity. Calories are estimated with the equation calories = METs x body weight in kilograms x duration in hours, where one MET is the energy used sitting quietly. Swimming at freestyle laps, moderate is rated at 5.8 METs. Real burn varies with fitness, technique, terrain, and effort, so treat these as close estimates, not exact counts. This is educational and not medical advice.

Frequently Asked Questions (FAQ)

How many calories does swimming burn in 30 minutes?

In 30 minutes of swimming, a 155-pound person burns about 204 calories. This estimate is based on the MET value of the activity and the person's body weight.

How many calories does swimming burn in an hour?

Swimming for one hour allows a 155-pound person to burn approximately 408 calories. This is calculated using the MET value for swimming and the individual's weight.

Is swimming good for weight loss?

Swimming can be effective for weight loss, as it burns calories based on body weight, duration, and intensity. Higher intensity swimming can lead to greater caloric burn, aiding in weight management.

How accurate are these swimming calorie estimates?

These swimming calorie estimates are based on a MET value of 5.8 and the individual's body weight. While they provide a general guideline, actual calorie burn may vary based on personal factors.
