Exercise is known to improve quality of life and physical function in breast cancer survivors.

PURPOSE: The overall objective of this study was to determine the effectiveness of a unique goal-orientated triathlon training program on improving physiological and psychosocial health outcomes on a diverse and overweight female breast cancer survivor patient population.

METHODS: Twenty-nine female breast cancer survivors (age= 52(7) yr, BMI =29 (6)) having undergone systemic breast cancer treatment, participated in a 14 wk individualized triathlon training program. Training comprised two supervised group sessions and three home-based sessions per week. The program culminated with participation in a sprint triathlon (Athleta Iron Girl, 0.5 mi swim, 12 mi bike, 3.1 mi run). Pre- and post-training outcome measures included: quality of life (FACT-B), cancer related fatigue (FACIT-F), isokinetic peak knee extensor and flexor torque at 60, 180, and 300 degrees/sec, peak arm flexor and extensor torque at 60, and 120 degrees/sec), six-minute walk test (6MWT), and body composition (bioelectrical impedance). Focus groups were used post-training to assess common themes related to training participation. Analyses were by paired t-tests and Wilcoxon Signed Ranks (questionnaires).

RESULTS: Data are mean (SD) from 23 subjects who completed pre and post intervention measurements. FACT-B improved (pre = 115 (14), post = 127 (8), p = 0.001) as did FACIT-F (pre = 41 (10), post = 48 (4), p

CONCLUSIONS: Goal oriented triathlon training in breast cancer survivors can improve functional capacity, improve quality of life and lessen fatigue. Feeling like part of a team with a common goal may have facilitated successful participation. Thus, goal-oriented training could lead to better health in breast cancer survivors.
