Were you using a flash and was the camera in burst mode? If you were using a
flash, the flash needs time to recharge before it can fire again.

Look at the exif data in the photos and check the shutter speed. What
metering option were you using. First guess is you metered of
something bright, like a bunch of white uniforms or bright background
in the later and the camera dropped to a faster shutter speed. Better
to use shutter priority or fully manual mode in these cases.

If you're inside the gym, then the ilumination is fixed (doesn't
change). So, set your camera on Manual, with the right exposure (take a
few shots with different settings, and check the histogram on the LCD).

When you find the right exposure, lock it -> put the right aperture and
shutter speed in manual mode.

Or, were you using flash? The flash gun may not be recycling fast
enough to properly illuminating the subject.
