## 3 Results  
The baseline demographics of the study participants are listed in Table 2.  
At the 3-month follow-up, four participants were lost to follow-up (12.5%). After the 3-month training intervention, the participants showed a statistically significant increase in the number of repetitions per exercise in all four resistance exercises (Figure 2), and they achieved a significant increase in distance walked during the 6 WT (\(p\) = 0.01), but they showed no increase in TUG time (\(p\) = 0.89) (Table 3). \begin{table}
\begin{tabular}{l l} \hline  & **Participants** **Included (\(n\) = 32)** \\ \hline Sex (male/female) & 4/28 \\ Mean age, years (min-max) & 80 (60–96) \\ Mean years since femoral neck fracture (min–max) & 3 (1–7) \\ FNF/THA side (right/left) & 15/17 \\ Oxford hip score (min–max) & 32 (15–49) \\ New mobility score (min–max) * & 7 (4–9) \\ \hline \end{tabular}  
* NMS was \(<\)8 at the time of inclusion in the outpatient clinic. However, a small change was presented for a few patients, explaining why the max was nine at the baseline (the first functional test) in this table.

Figure 2: The progression of the total number of repetitions of each of the four exercises from the start of the intervention to the final training during the intervention. Ex 1 = chair raises; Ex 2 = knee bends; Ex 3 = standing walk; Ex 4 = pelvic raises. \begin{table}
