Based on Kaa's study of an anthropomorphic velociraptor (assuming that Kaa actually did it). 

The sun appeared over the eastern horizon.  The birds were chirping the beginning of the day, and the mice and other mammals were waking up out of their dens to gather food through out the day. A lone figure emerged from his tent from sleeping.  To day was the day of his hunt.   The scales on his body gave a certain pattern, one that gave him camouflage from his prey.  His eyes, were predator's eyes, and were young for eyes.  His teeth were sharp, like those of a predator.  His body, lean and muscular.  His hands had four digits and a thumb, each ending in a claw.  His tail was long and sinuous, and provided balance.  His loins had a penis and a scrotum dangling down his front, covered in those fine scales.  And his feet:  he stood on his heel, but ran mostly with his upper foot striking the ground rather than his heel.  five of them, and his big toe ended in a wicked upturned claw.  The claw was his means of self defense.  

He walked outside, nude.   He prepared his breakfast by catching fish, and then gutting them and cleaning them out.  He then skewered them with sticks and put them up around the fire.  As his fish cooked, the hunter then started to wrap his tail in golden cords.  To the primitive natives, gold had no value other than it could be beaten or spun into fiber.  With his tail wrapped, he ate his fish.  Anticipating the hunt, he finished his meal in just fifteen minutes.   He then proceeded to wrap his feet with golden cords.  With his feet wrapped and his wrists covered with bronze bracers, the raptor grabbed his spear and started to look for his prey.  And there it was, a beautiful golden gazelle. 

He then stood up and started to run after his prey.  His prey, noticing it was going to become dinner, started to run away.

The human body is superbly adapted for long distance running.  Whether or not the Savanna Theory is correct, there is no doubt that the body has many pores that allows it to sweat to control body temperature.  The gluteus maximus was not designed to attract the eyes of the amorous, but to provide support for running.  Every muscle in the body is adapted to move, and the human body can move.  This is the gist of the endurance running theory of anthropological evolution.

Unlike most dinohunters, the raptor could run.  His body began to sweat, to keep him cool.   The sweat appeared on his bald head, except for the feathers he used to adorn his head; on his arm pits, his back and his front, his legs, and his groin.  He also sweated through his palms and his arms.  This maintained his warm body's temperature while running.  His muscles rippled as he ran, and when he ran, he struck the ground with his toes.   The rippling effect, mostly caused by subcutaneous fat and intra-muscular fat, was not pronounced as it would be in some one out of shape.  But his muscles did ripple, but not as much as you would expect.  This raptorian man was built to be a lean hunter, hunting for his family.

He ran the gazelle down, and the gazelle went into a full gallop.  But our nude hunter was persistent.  He kept running, his upper toes always struck the ground when he ran.  Aside from the fish that he ate, he also drank a low alcohol beer that contained all the carbohydrates he needed to prevent using proteins.   The gazelle continued to run.  As an ungulate, the gazelle was the target of the raptorian man.  Lacking the sweat glands that the raptorian man had, the animal tried to pant with it's heat exchange, but its body had begun to overheat.  But it had to run, for it's life.   It needed to survive, not be food on the dinner table.  It continued to run, and run for its life. 

Overtime, the gazelle started get tired.   It tried to get away, running for its life, and most hunters would have tired by now.  But not this smart, built raptorian man.  He too had a family to feed, and this is what driven him to continue running after his prey.  The gazelle had to find somewhere to hide, but the hunter would eventually catch up to the gazelle.  It had to rest, before the animal overheated.  The sapient raptor, however, continued to run, stopping every once in a while to track the animal and stay on the trail.   The gazelle stopped running, and started to pant, and take in water to replenish and cool his body temperature.  He had to stop and rest here.  The gazelle then sat down on it's legs and continued to drink from the river.

The sapient raptorian man tracked the gazelle here, to this river.  He passed up another herd of gazelles for this one.  He needed to stay on target, and found this one resting.  Knowing that it would be some time before he got up and ran again, the raptorian stopped but kept in running mode.  Although his body also begged for recovery, his smart sapient mind overcame his body and he got up, stalked his tired prey.  when he was but five feet from his prey, his prey looked at him and in a second the spear came down and pierced flesh and bone to the heart of the animal, and the animal was slain.  The hero yelled out a victorious yell, as a thank you for nature providing him and his family with more to eat.

When the day was done, the hunter came back with the gazelle on his shoulders.  It had been gutted and cleaned, and now it needed to be skinned.  His family, all naked, would come together and help with the tanning of the leather.  They would skin the animal and preserve what meat they had for use.   It was a successful day of hunting, and for this family, which lived with other families in a tribe, hunting and foraging could mean that one ate for a day, or starved the next.
