In addition, blood biochemical (pH, HCO3-, and lactate) responses measured in three occasions were investigated. Thirteen male well-trained sprinters (24.65±3.44 yrs) performed two consecutive trials (7 days apart). Athletes were assigned randomly either to ingest a single dose of NaHCO3 (0.3 g/kg) 1 h prior to exercise or placebo using a double-blind crossover design. The intermittent sprint test consisted of 60 s treadmill sprints (90% of maximal work done) and 30-s recovery repeated intermittently until volitional exhaustion. Blood samples were collected from all athletes before exercise, after 1 h of dose intake, and after exercise in each trial. Paired sample t-testing showed that athletes complete significantly more sprint repetitions (p=0.036) during the intermittent sprint test with NaHCO3 (6.846±3....

One of these important domains is physical self-esteem (Fox & Corbin, 1989) that can be described as a multidimensional hierarchical subjective perception and affective evaluation of people's various physical traits. The physical self has been considered as one of the most important factors correlated to global selfesteem throughout all ages (Fox, 2000). Moreover, Harter (2012) reported that perceptions of physical appearance, which is known to be the physical selfesteem domain (Marsh, Richards, Johnson, Roche,
