Effects of Upper Body Exercise Training on Aerobic Fitness and Performance in Healthy People: A Systematic Review.

This systematic review aimed to evaluate the effects of upper body endurance training (UBET) on oxygen uptake (VO) in healthy persons and derive evidence-based recommendations to improve upper body fitness and performance. : Databases were systematically searched in accordance with PRISMA guidelines until 1 February 2023. Eligibility criteria included healthy male and female adults and older adults who underwent an UBET intervention.

6-week High-intensity Interval Training (HIIT) of the Lower Extremities Improves VO2max of the Upper Extremities.

High intensity interval training (HIIT) is widely used to improve VO. The purpose of this study was to examine if lower extremity HIIT resulted in improved maximal oxygen uptake (VO) and peak power output (PPO) of the upper extremities. Twenty healthy and trained participants (11 female and 9 male, VO 3160±1175 ml/min) underwent a 6-week HIIT program of the lower extremities on a cycle ergometer.

Functional Vs. Running Low-Volume High-Intensity Interval Training: Effects on VOmax and Muscular Endurance.

The purpose of the study was to assess if high-intensity interval training (HIIT) using functional exercises is as effective as traditional running HIIT in improving maximum oxygen uptake (VOmax) and muscular endurance. Fifteen healthy, moderately trained female (n = 11) and male (n= 4) participants (age 25.6 ± 2.

Freeriding-Only a need for thrill?: Comparing different motives and behavioural aspects between slope skiers and freeride skiers.

Objectives: To compare professional freeride skiers (an experienced high-risk cohort) with recreational freeride skiers (a less experienced high risk cohort) and slope skiers (a low-risk sport cohort) in regard to their motives and their reported accident involvement.

Design: Case-control study.

Methods: In an online survey, skiers completed the German Sensation Seeking, Emotion Regulation and Agency Scale and the German Accident and Close Calls in Sport Inventory.

Is the cross-over effect of a unilateral high-intensity leg extension influenced by the sex of the participants?

Background: While performing a unilateral muscle contraction, electrical muscle activity also arises in the contralateral homologous muscle, muscle group, or limb. When the muscle contraction induces muscle fatigue, females show not only a greater resistance than males but also a reduced contralateral muscle activation. The study aimed at investigating whether, during a high-intensity 30-s unilateral maximal effort isometric leg extension exercise, the contralateral non-exercising limb (NEL) knee extensor muscle activation would differ between females and males.

[Secondary Full Title: Effects of high intensity interval training in plain and uphill regarding physical performance].

Background: As the number of HIITs is increasing in competitive and non-competitive sports, the risk of injuries and overload is increasing. There are no scientific data to support specific recommendations in regard to intensity, duration, number of intervals and gradient for HIIT that result in improved muscular parameters in athletes. Therefore the aim of this study was to compare HIIT in plain and uphill exercise, with respect to exercise tolerance and improvements in performance (VO and 800 m running time in the plain and uphill).
