General minimum velocity threshold for one-repetition maximum prediction in two squat variations: does the load –velocity profiling approach matter?
Conclusion1RM can be estimated with similar accuracy with all profiling methods, irrespectively of the back squat variation. However, the free-weight variation displays higher systematic and random errors. It can be concluded that the wide limits of agreement preclude accurate 1RM estimations on an individual basis.

Ski-orienteering: a scientific perspective on a multi-dimensional challenge
AbstractSki-orienteering, which combines cross-country skiing with orienteering, dates back to the late 1800s, with the first World Championships in 1975. While researchers have explored the physiological and biomechanical determinants of success in cross-country skiing and orienteering separately in detail, scientific knowledge concerning ski-orienteering remains limited. Based on the information that is presently available together with interviews with elite ski-orienteers, we explore here for the first time the historical development, physiological, biomechanical, and psychological demands, certain training strategies, ...

Optimum power load profile in squat and countermovement jump protocols
ConclusionWe concluded that the optimum power load for CMJ and SJ were at 0% BM taking peak power output and mean power output as outcome variables. The identification of optimum power zone did not differ if using absolute or relative power (scaled by BM). The MVP related to the optimum power load zone differed between CMJ and SJ.

Acute effects of high-intensity interval training and moderate-intensity continuous training on left ventricular function in women with uncomplicated obesity
ConclusionA single bout of HIIT promoted transient reductions in LV function that were almost completely reestablished near baseline values 35 min after exercise cessation, not implying, therefore, any risk to HIIT performance by this population.Trial registration numberRBR-3v3dqf (Registered on 07/05/2019).

Improving lower limb muscle strength according to number of weeks of core stability exercises in female athletes with and without ACL injury
ConclusionsThe number of weeks of core stability exercise had a significant effect on improving the strength of the lower limb muscles. These effects were different in healthy athletes and athletes with a history of ACL injury. As, in healthy athletes in some muscles such as the hamstring, there was a significant effect after 8 weeks only, while in athletes with a history of ACL injury, there was a significant effect after 1 week in all muscle groups. Therefore, it is recommended that therapists and sports trainers consider the optimal number of weeks of core stability exercise in the design of training programs for fem...

Optimizing resistance training for body recomposition in postmenopausal women
AbstractWe investigated the effectiveness of a resistance training (RT) protocol with lower volume and lower load in the body recomposition of postmenopausal women, and to determine whether changes in body recomposition induced by RT would be associated with changes in physical performance, independently of confounding factors. Participants were randomly assigned to one of three groups: I) Single set-high load (SSHL,n = 14, 1 set of 8 to 12 maximum repetitions), II) Single set-low load (SSLL,n = 15, 1 set of 25 to 30 maximum repetitions), and III) Multiple sets-high load (MSHL,n = 14, 3–6 sets of 8 to 12 maxi...

Effects of online and face-to-face exercise training compared in healthy older adults: a feasibility study
AbstractBackgroundSupervised online exercise training (OET) may help to counteract physical inactivity in healthy older adults. Few studies to date have compared the effect of OET and traditional face-to-face exercise training (TET).AimsWith this study we compared the effect of OET and TET on physical function in healthy older adults and investigated the feasibility of OET.MethodsPower analysis indicated that a sample size ofn = 20 per group was necessary to detect a moderate effect size. Of 80 individuals potentially interested in the study, 32 did not meet the inclusion criteria and 22 declined participation; 26 were...
