Los Angeles Lakers star LeBron James believes he is "getting better and better" after he set yet another NBA record.

James became the oldest player in league history, at the age of 36 years and 346 days, to register a 30-point triple-double as the Lakers beat the Orlando Magic 106-94.

According to ESPN, James overtook the late Kobe Bryant, another Lakers great, who was aged 36 years and 99 days when he accumulated 31 points, 11 rebounds and 12 assists in a win over the Toronto Raptors in 2014.

James had 30 points, 11 rebounds and 10 assists on Sunday. He missed a chunk of games through injury at the start of the season, but still ranks third in the Lakers' roster for points (420), behind Russell Westbrook (546) and Anthony Davis (600).

"Who me? How do I continue how I'm playing? Been doing it for 19 years," James told reporters when asked how long he can maintain his recent form.

"Just do what I've been doing. I feel like I'm getting better and better each and every day. I'm getting healthier and healthier.

"That's just my mindset. Don't get involved in how many minutes I played, how many days off.

"I don't confine to that. I think you think negative thoughts or negative energy, it just creeps into your mind. So, I'm as young as I've ever been."

James played both road games in a double-header against the Memphis Grizzlies and Oklahoma City Thunder last week, collecting 53 points, 15 rebounds and 17 assists across those appearances.

His performance on Sunday was put down to getting plenty of rest upon his return to Los Angeles, though that only came after a trip to Phoenix to see his son in action.

"I slept last night from 12 [a.m.] to 8 [a.m.], I got up, ate breakfast and went back to sleep from 8:30 [a.m.] to 12:30 [p.m.]," James explained.

"Sleep. Sleep and inspiration from my son and his team."

Westbrook, who scored 19 points and had seven rebounds against the Magic, added of James: "When he's just being aggressive, he's aggressive in making the right plays and reads, our team's different.

"Tonight was another night where he imposed his will."
