Abstract
Objective: The intervention of resistance training and consumption of alkaline water may affect the physiological adaptations of skeletal muscles. The combined effect of resistance training and alkaline water has not been investigated on muscle damage indicators and muscle hypertrophy responses in non-athletes and there is limited information in this field. Therefore, the aim of this research was to investigate the interactive effect of eight weeks of resistance training and alkaline water consumption on serum levels of creatine kinase (CK), lactate dehydrogenase (LDH), growth hormone (GH), testosterone (T), and insulin-like growth factor-1(IGF-1) in untrained men.
Methodology: The current research was a double-blind semi-experimental. For this purpose, 60 untrained men (age 24.15±2.17 years and weight 77.24±3.46 kg) voluntarily participated in this research. The subjects were randomly divided into four groups of 15 people: resistance training (RT), alkaline water (AW), resistance training + alkaline water (RT+AW) and control (C).
RT intervention (3 × 10 reps, 90 s rest, 70-85% 1RM) was implemented for eight weeks and three sessions per week. AW (pH 9.5) at the rate of 12 kg/mL was received after each training session for 8 weeks. Blood samples were taken before and after the last training session to measure the levels of CK, LDH, GH, T and IGF-1. The data were analyzed using two-way ANOVA test with repeated measures and Tukey's post hoc test at a significance level of α=0.05.
Results: The results showed that after eight weeks of RT with AW consumption was observed highest percentage of significant changes in serum levels of CK (+5.13%, p=0.040), LDH (+4.69%, p=0.032) =), GH (+8.48%, p=0.017), T (+6.49%, p=0.028), and IGF-1 (+6.28%, p=0.024). The main effect of RT was significant on serum levels of CK (+10.24%, p=0.045), LDH (+8.60%, p=0.031), GH (+6.11%, p=0.022) =), T (+4.60%, p=0.035) and IGF-1 (+3.57%, p=0.043). The main effect of AW consumption was not significant on the above indicators (P>0.05).
Conclusion: The combined effect of RT and AW causes more physiological adaptations for muscle hypertrophy in untrained men.
