Next, Madzima et al. engaged 33 breast cancer survivors in a 12-week full-body resistance training program, 2 days/week utilizing 10 exercises for 2 sets of 10 repetitions and a last set performed to complete fatigue at 65%–81% of their one repetition maximum (1RM). In 17 of the subjects, the resistance training intervention was also combined with a 20-g protein supplement (whey and casein blend), consumed twice a day. Although the protein did not provide additional benefits, increases in strength (up to 32%) and lean mass (+0.9 ± 1.0 kg), and decreases in fat mass (-0.5 ± 1.2 kg), and body fat percentage (-1.0% ± 1.2%) were observed. In conclusion, this training intensity (65%–81% of 1RM) improved lean mass more than has been previously reported in breast cancer survivors participating in a resistance training intervention.
Finally, Herrick et al. reported on three US Volleyball National Team members who underwent a comprehensive genetics evaluation as well as cardiac screening. As indicated by one of the cases, people with Marfan syndrome may not present with all of the typical clinical phenotype features. In this case, the subject was tall but had no other overt clinical features of Marfan syndrome. Only by performing a screening echocardiogram was an aortopathy identified. Genetic testing then confirmed the diagnosis of Marfan syndrome, and for this reason it was recommended that he cease playing competitive volleyball. Overall, these case evaluations on three athletes suggest that clinical screening combined with genetic testing in tall athletes may be warranted because it can lead to the identification of individuals with previously undiagnosed aortopathies who are at risk for life-threatening aortic dissections.
