Abstract
The purpose of this study was to investigate the combined effects of Channa
Striatus supplementation with countermovement jumping exercise for 12 weeks on
bone parameters, muscular performance, and antioxidant status. A parallel randomised
controlled study was conducted among young inactive males for a 12-weeks
intervention period. Thirty-eight healthy physically inactive young males aged 21.7 ±
1.44 years old were recruited and randomised into four groups: control group (C)(n=9),
Channa Striatus supplementation group (CS) (n=9), jumping exercise group (J) (n=10)
and combined jumping exercise with Channa Striatus supplementation group (CSJ)
(n=10). Participants in J and CSJ groups performed countermovement jumping
exercise 3 times per week for 12 weeks which consisted of 2 sessions per day with 6
hours resting period between the sessions in each day. Participants in CS and CSJ
groups consumed 1 tablet of Channa Striatus (500mg) in the morning every day for
12 weeks. Parameters measured at pre- and post-tests included body composition, bone
speed of sound (indicator of bone mineral density), jumping power and force,
isokinetic muscular peak torque (strength) and power, blood bone turnover markers,
blood oxidative stress markers and testosterone concentrations. There were significant
increase (p < 0.05) of bone speed of sound midshaft tibia in CS, J and CSJ groups at post-test. Besides, CS group showed statistically significant decreased (p < 0.05) in
serum bone alkaline phosphatase (BALP) after 12 weeks of intervention period.
Statistically significant greater values (p < 0.05) were observed in J and CSJ groups in
dominant and non-dominant leg isokinetic muscular peak torque and power at 60o.s-1
and 300o.s-1 angular velocities compared to C group. In addition, there was statistically
significant higher value (p < 0.05) in CS group in dominant and non-dominant leg of
isokinetic muscular peak torque and power at 300o.s-1 angular velocity compared to C
group. Serum protein carbonyl concentration in J and CS groups increased
significantly (p < 0.05) at post intervention. CS, J and CSJ groups had significant
decreased of serum malondialdehyde concentration (p < 0.01) at the end of the study.
There were significant decreases of serum testosterone concentration (p < 0.05) in CS
and CSJ groups after intervention. Next, serum albumin concentration was
significantly increased (p < 0.05) in CSJ group at post-test. These study findings imply
that combined Channa Striatus supplement and countermovement jumping exercise
(CSJ), jumping exercise alone (J) and Channa Striatus supplementation alone (CS) for
12 weeks elicited greater beneficial effects on bone health status, muscular strength
and power and improved antioxidant status compared to control groups (C) generally.
Hence, combining countermovement jumping exercise and Channa Striatus
supplementation has potential to be recommended for enhancing bone health status,
muscular performance, and antioxidant status.
