الملخص EN

Many people are exposed to physical fatigue during their daily work, especially after the heavy reliance on technology, which contributed to what is known as fidgeting, which prompted those interested in the field of sports and health to give tips and instructions and educate people about the danger of lack of movement and decreased activity caused by fidgeting.

the study was to investigate the effect of caffeine intake on the physical performance endurance time of (8) participants in resistance training in physical centers, who underwent a caffeine experiment 6 mg / kg, with a time difference of one week.

the experimental method was used within the experiments that require uniformity in all conditions.

the study protocol included subjects to undergo resistance exercises (leg / knee extension, and squat) at an intensity of 70% of the maximum repetitions and volume at a rate of 5 sessions × 10 repetitions and a rest period of 40 seconds between repetitions and 3 minutes between the two exercises.

after a 3-minute rest period after the end of the resistance exercise, subjects were tested for running at increased speed on a treadmill.

it started running at 8 km / h, and was increasing by 1 km / h every 3 minutes.

running time was recorded, and blood samples were drawn to measure the study's hormone variables.

the results showed which run time was longer in the caffeine trial (189.9+1.06 min).

it has been concluded that the running time is longer with caffeine, possibly because it is a central nervous system stimulant.
