INTRODUCTION:
Optimizing resistance training through periodization is essential for improving strength performance. In this context, undulating resistance training is considered an effective method for structuring resistance training in healthy recreational and competitive athletes (Harries, Lubans, & Callister, 2015). However, to date there are no studies in the field of exercise oncology that have compared volume-matched undulating strength training with traditional hypertrophy training in cancer survivors.
METHODS:
37 breast and 30 prostate cancer survivors were randomly assigned to either undulating (UND, n = 34, age 60±9 years) or standard hypertrophy training (STD, n = 33, age 58±11 years). Both groups performed two machine-based resistance trainings per week with matched training volume over an intervention period of 12 weeks. As primary outcome, strength performance of the knee extensors was assessed by maximal isokinetic peak torque (MIPT) and one-repetition maximum (1-RM) test. In addition, MIPT and maximal voluntary isometric contraction (MVIC) for knee, hip and elbow extensors/flexors as well as 1-RM for leg curl, rowing, lat pull-down, leg press and shoulder press were examined.
RESULTS:
27 (UND) (13 women) and 26 (STD) (16 women) patients were included in the analysis. Concerning the primary outcome, MIPT (p<.05) and 1-RM (p<.001) show that both groups significantly improved knee extensor strength. There was no significant group difference. Comparably, nearly all secondary endpoint parameters showed significant strength gains over time without group differences (p>.05).
CONCLUSION:
Undulating and standard hypertrophy resistance training both resulted in comparable effects on strength performance in cancer survivors. Both training regimens showed no differences with regard to safety and feasibility in cancer survivors.
