Design outcomes

Primary

Measure	Time frame
In this clinical pilot study we evaluated the sport and exercise therapeutic outcome within an in-patient rehabilitation context using a prospective quasi-experimental design with two repeated measures. All newcomers to a local rehabilitation clinic were invited to participate in this study provided they matched the inculsion criteria. In our balanced experimental design all voluntary participants were either assigned to a control group or - consecutive to an essential reorganization in everyday clinical processes - to an intervention group. This sample had been prescribed to rehabilitate from their ischemic heart failure for three weeks, a common medical standard in the German health care system. The intervention group (IG) completed a unitized individualized physical training program, while the control group (CG) completed a rehabilitation program according to common procedures. Both sample groups were controlled for homogeneous socio-demographic and physiological parameters. We used a two way analysis of variance design with repeated measures to identify main and interaction effects for the following parameters (dependent variables): relative maximum oxygen uptake (VO2peak), heart rate reserve (HRR), maximum heart rate (HRmax), heart rest rate (HRrest), maximum performance (Wmax), 6-minutes walk test (6-MWT). Additionally, parameters of heart rate variability were analyzed. time domain: SDNN (ms2); RMSSD (ms2); pNN50% frequency domain: TP (ms2); VFL (%); LF (%); HF (%); LF/HF The two sample groups (CG, IG) and the two repeated measures times (t1 = pre test, t2 = post test) served as independent variables, respectively. The statistical significance level was set at p = .05. In addition to the level of significance, effect sizes were calculated and specified by the coefficient eta square. The interpretation was based on Cohen (1988). Measurement and research methods To evaluate the physical performance, a cardiopulmonary exercise test and a 6-minutes walk test	—
