PURPOSE This study examined parameters derived from both an incremental step-wise and a ramp-wise graded rowing exercise test in relation to rowing performance. METHODS Discontinuous step-wise incremental rowing to exhaustion established lactate threshold (LT), maximum oxygen consumption (VO(2maxSTEP)), and power associated with VO(2max) (W VO(2max)). A further continuous ramp-wise test was u...

For integers $$2 \le t k$$ , we consider a collection of k set families $${\mathcal {A}}_j: 1 j where {A}}_j = \{ A_{j,i} \subseteq [n] : i m \}$$ and $$|A_{1, i_1} \cap \cdots A_{k,i_k}|$$ is even if only at least the $$i_j$$ are distinct. In this paper, prove that $$m =O(n^{ 1/ \lfloor k/2 \rfloor })$$ when $$t=k$$ $$m=O(n^{1/(t-1)})$$ $$2t-2 both these bounds best possible. Specializing to c...

Let f(l,t,n) be the maximal size of a family F ⊂ 2[n] such that any l ≥ 2 sets of F have an exactly t ≥ 1-element intersection. If l ≥ 3, it trivially comes from [8] that the optimal families are trivially intersecting (there is a t-element core contained by all the members of the family). Hence it is easy to determine f(l, t, n) = ⌊ l 2(n− 1) ⌋ +1. Let g(l, t, n) be the maximal size of an l-wi...
