With a three-game road trip looming (Atlanta, Chicago and Philadelphia), Heat players returned to work Tuesday as an upbeat group, riding the emotional high of a seven-game winning streak and eager to embark on a 32-game-in-57-days post-All-Star break odyssey that will carry them into the playoffs.

“After the All-Star break, it’s time to really start putting everything together,” Chris Bosh said. “The games are going to start getting more intense, and guys are really, really playing for something.”

Concerns about the Heat’s uneven play on the road have dissipated somewhat after convincing recent wins in New Jersey and, particularly, Oklahoma City.

“We have a heck of a March ahead of us, and this is the time of year everyone playing for something looks forward to,” coach Erik Spoelstra said. “You can see the light at the end of the tunnel.”

Dwyane Wade cautions: “It’s going to be a tough second half” — including nine sets of back-to-back games. That doesn’t concern LeBron James, who noted Tuesday: “I get stronger on back-to-backs.”

Sizing up where each of the key players stand heading out of the break:

•  James: No player in history has ever produced the collective numbers that James is averaging this season: 27.3 points, 8.2 rebounds, 6.9 assists and shooting 56.5 percent from the field. And there’s this: James had made 69 percent of his shots over the past seven games — including 51 for 61 in the paint and 14 for 26 on threes.

“He’s the most-versatile player of all time,” Magic Johnson said. “Kudos to him for improving his game.”

•  Wade: Spoelstra contends he’s playing more efficiently than ever. His scoring average (21) is nearly four points below his career average, but he’s shooting a career-high 50.5 percent, best among two guards. And he seemingly has regained his lift after offseason knee surgery.

•  Bosh: The offensive numbers are impressive: His 55.5 shooting percentage is well above his first two seasons with the Heat (49.6 and 48.7). And in the final five minutes of close games (margin of five or less), Bosh has made 18 of 21 shots — easily the best in the league. His 7.4 rebounding average would be a career low, but he enters Wednesday with three consecutive double-figure rebounding games for the first time all season.

•  Mario Chalmers: His shooting percentage has dipped from 44.8 to 41.3, and he can exasperate with his uneven play. But this is encouraging: Given more responsibilities to set up the offense, Chalmers has 29 assists and just six turnovers in his past nine games, and his overall turnover average has dipped from last season (2.2 to 1.4). And has the Heat’s second-best plus/minus ratio (behind James), with Miami outscoring teams by 364 with Chalmers on the court.

•  Udonis Haslem: Spoelstra said he’s back from a leg injury and will start Wednesday. Despite starting 31 games, he’s averaging just 19 minutes — about 10 below his career average. His rebounding (13.6 per 48 minutes) is down only slightly from recent years, and the Heat’s best plus/minus lineup features Haslem with the Big 3 and Chalmers. But he’s shooting just 32 percent on all attempts beyond two feet.

•  Shane Battier: Beyond his steady defense, what has been particularly helpful has been the renaissance of his three-point game: he’s 39.9 percent shooting, compared with 33.1 the past two seasons. He has been deadly on corner threes (46 percent), and Spoelstra said the Heat’s ball movement is at its best when Battier is getting those shots.
