Erratum to: Eur J Appl Physiol (2017) 117:1095–1106 DOI 10.1007/s00421-017-3596-y

The author would like to correct the errors in the publication of the original article. The corrected details are given below:

In the abstract, second sentence of the result section should read as:

Results KL reduced spinal flexion and range of motion at the hip joint and indicated more muscle activation in the triceps. Performance (W kg−1) was impeded in both WIN (KH 1.40 ± 0.30 vs. KL 1.13 ± 0.33, p < 0.01) and MAX (KH 0.88 ± 0.19 vs. KL 0.67 ± 0.14, p < 0.01). KH resulted in lower lactate concentration, anaerobic metabolic rate, and minute ventilation for equal power output.

In the Results, Physiology section, fifth paragraph should read as:

RER was higher in KL than KH during SUB [main effect of position F(1, 5) = 22.42, p < 0.01] but showed no difference during MAX (Table 2). During SUB, GE was between 5.2 and 6.9% and increased with increasing workload. No difference in GE was observed between sitting positions in SUB2–4 [no main effect of position F(1, 6) = 1.74, p = 0.24, Table 2]. Higher total metabolic rate (MRtot) was observed for KL [F(1, 5) = 10.27, p < 0.05] and showed no difference in MAX (p = 0.15) which resulted in higher efficiency (PO/MRtot) in MAX for KH (3.9 ± 0.7 vs. 3.2 ± 0.6%, p < 0.05).

In the Conclusion section, third sentence should read as:

The KL position was also associated with improved respiration, but it impeded performance.

In Table 2, GE row was incorrect. The correct table is given below:
