| Resumo: | Background: high-intensity interval training (HIIT) is considered a time-efficient approachto
improve health and physical fitness parameters. HIIT protocols with different intervalsrecovery duration elicit physiological and perceptual effort response distinct. However, studies
investigating the effect of low-volume HIIT session with different interval-recovery durations
on muscle damage markers are scarce, especially in no-athletes. Objective: to compare the
effect of low-volume HIIT sessions with different interval-recovery durations on muscle
damage markers in recreationally trained men. Methods: twenty-five participants (22.3 ± 2.9
years; 24.6 ± 2.7 kg/m2
) performed two low-volume HIIT sessions (10 x 60 s e 20 x 30 s at
100% of maximal velocity of treadmill interspaced with same time of passive recovery) in
randomized, counter balanced crossover order separated with one week. Delayed onset muscle
soreness (DOMS) and counter movement jump (CMJ) were measured before,24 and 48 hours
after the sessions. The pain threshold (PT), pain tolerance (PTol) and pain intensity (PI)
measured by algometer of pressure were assessed rectus femoris, biceps femoris and
gastrocnemius muscles. Generalized estimated equation was used to verify the session and time
interaction on outcomes. The linear and gamma distribution models were tested, with identity
function link and autorregresive correlation matrix. The final distribution was defined acording
to the maximum likelihood estimation under the independent criteria model. The gamma
distribution was better for all variables. The Bonferroin post hoc was used to pair comparions.
Results: there were no significantly session and time interactionsfor PT, PTol and PI in all
analyzed muscles (P-values > 0.260). Additionally, there was no significantly session and time
interactions for CMJ (P = 0.836). Conclusion: low-volume HIIT sessions with different
interval-recovery durations do not significantly elicit changes on muscle damage markers
exercise-induced 24 and 48 hours after sessions in recreationally trained man. |
