Childhood Cancer Survivors' Quality of Life

Hodgkin’s lymphoma is a cancer that affect the lymphatic system. Resistance training (RT) can be an effective alternative in reducing the deleterious effects of cancer treatment, such as lean mass loss and fatigue. However, there are no studies to date on the appropriate rest interval (RI) between sets of RT exercises in Hodgkin’s lymphoma survivors (HLS) so more effective RT programs can be designed and implemented in this cancer population. PURPOSE: To evaluate the acute effect of different RIs in isokinetic muscle performance of HLS after treatment. METHODS: This is an early exploratory study, which evaluated 9 HLS who had completed treatment within at least 6 months, with mean age 34.11 ± 10.35 years. The HLS performed an isokinetic exercise - unilateral extension of the right knee - consisting of three sets of 10 repetitions at 60°/s, with 3 different rest intervals (1, 2 and 3 min) between sets. The three exercise protocols were performed on different days, separated by a minimum of 72 hours and maximal of 1 week between each session; RIs trials were randomized and counterbalanced. The isokinetic muscle performance was evaluated by peak torque (PT) and total work (TW). Before the exercise protocol, volunteers performed a warm-up consisting of two sets of five repetitions at 60°/s with 1 min rest between sets. Kolmogorov-Smirnov test confirmed data normality. A three-way ANOVA was used to analyze data, with Bonferroni post hoc. A significance level of p <0.05 was used for all analyses. CONCLUSIONS: Results indicate a decline in the PT and TW in all sets regardless of the different RIs. However, the decline of performance was lower as the RI was increased, suggesting that HLS need a longer RI (at least three minutes) to better recover between sets.Table: No title available.
