Aim. The aim of the study is that among exercise programs with different resting intervals, short resting intervals negatively affect LDH and CK enzyme activity.
Methods. The study included 28 male volunteers (age 20.50+2.40 years, weight 72.80±5.75 kg, l74.65±l2.45 cm height) who did not regularly exercise. Study participants were randomly divided into two groups, with one group having 1 min resting interval (RIG-1) and the other group having 3 min resting interval (RIG-3), both working at 60°/sec speed isokinetic muscle strength. LDH and CK concentrations of both groups were measured in pre-test and post-test, 24 h (after 24 hours), 48 h (after 48 hours) and 72 h (after 72 hours).
Results. Significant differences were found between the post-test and 24 h values of LDH concentrations of RIG-1 participants (p=0.023, p=0.012). In CK concentrations RIG-1 participants showed significantly different CK concentrations between 24 h and 48 h tests (p=0.021, p=0.018).
Conclusion. Resistance exercises should be planned considering training days, and resting intervals and days. The findings of this study may help to optimize refreshment and resting intervals between training days for untrained individuals who have recently begun resistance exercises.
