Methods: Recruited and randomly assigned 28 healthy males to a core training group (COR) and a control group (CON). COR underwent 8-week core muscle resistance training, 3 days per week, with at least one day interval. Each set of exercises included plank, right and left side bridge, crunch, where each exercise was performed 3 sets for 50 seconds each with a 10 seconds rest in between. Measurements were conducted before training (pre), after the first training session (day 1), after the 8-week training (post) and 2 weeks after training program (post 2). Data collected included respiratory functions: maximum expiratory pressure (MEP), maximum inspiratory pressure (MIP); lung functions: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio (FEV1%), maximum voluntary ventilation (MVV); as well as core muscular fitness: back muscle strength, trunk flexor endurance test (TFET), sit up. Results: (1) In terms of acute response, day 1 FVC (4.39 ± 0.45 L) and day 1 FEV1 (3.71 ± 0.50 L/s) were significantly lower than pre (4.46 ± 0.49 L; 3.80 ± 0.48 L/s, p < .05). (2) Eight weeks of core muscle endurance training resulted significant improvement in core muscular fitness: back muscle strength, trunk flexor endurance test (TFET), sit up (pre: 87.26 ± 21.81 kg; 100.89 ± 48.80 sec; 24.24 ± 12.88 times: post: 100.09 ± 15.54 kg; 171.94 ± 60.09 sec; 37.88 ± 21.40 times, p < .05). However, no significant increase in respiratory muscle and lung functions could be found (p > .05). Conclusion: Eight weeks of core muscle isometric training significantly resulted in improvements in core muscular fitness, no significant training effects could be found in respiratory muscle and lung functions.
