Validity of simple field tests as indicators of elite female field hockey match performance.

Background: Due to the change in field hockey match format, the need exits for research to determine whether current fitness test are still valid indicators of match performance. This study aimed to determine the direct validity of the 5-m multistage shuttle test (5-m MST) and Yo-Yo Intermittent recovery level 1 test (Yo-Yo IR1) by correlating their results with external load measures in international field hockey matches.

Methods: Nineteen female field hockey players completed the 5-m MST and Yo-Yo IR1 before nine matches.

Positional and between quarter differences in physical demands of elite female field hockey players during international matches.

Objectives: The main aims of this study were to examine whether there are positional- and between-quarter differences in the physical load of elite female field hockey players during international matches.

Methods: Twenty-three international female field hockey players were equipped with Global Positioning Systems devices, while competing over nine international matches.

Results: Players covered a mean relative distance, relative player load, and distance covered in the form of low-, moderate-, and high intensity activities of 107.

Relationships between physical activity, body mass index, waist circumference and handgrip strength amongst adults from the North West province, South Africa: The PURE study.

Background:  Handgrip strength (HGS) serves as a proxy for the functional ability and its association with body composition (BC) and physical activity (PA) in South African adults are less clear.

Aim:  We investigated the relationships between PA, body composition and HGS amongst adults.

Setting:  Rural and urban population from North West Province, South Africa.

Comparison of the Morphological Characteristics of South African Sub-Elite Female Football Players According to Playing Position.

Limited information is available on the morphological characteristics of adult female footballers, therefore the aim of this article was to examine if there are position-specific differences in the morphological characteristics of sub-elite female football players and to establish normative standards for this level of female football players. The morphological features of 101 sub-elite female football players (age: 21.8 ± 2.

Effects of a Soccer Tournament on the Psychohormonal States of Collegiate Female Players.

Broodryk, A, Pienaar, C, Edwards, D, and Sparks, M. Effects of a soccer tournament on the psychohormonal states of collegiate female players. J Strength Cond Res 35(7): 1873-1884, 2021-A gap exists in the literature concerning the connection between soccer players' hormonal and psychological responses when playing a tournament, or even a match, and its outcome (victory or defeat).

The Use of GPS Analysis to Quantify the Internal and External Match Demands of Semi-Elite Level Female Soccer Players during a Tournament.

The purpose of this study was to make use of global positioning system technology to quantify the internal and external match demands of sub-elite female soccer players. Secondly, the study aims to describe the magnitude of change of these variables within and between matches over the course of a tournament to determine the effect of player fatigue. Thirty sub-elite female soccer players were assessed throughout a local tournament.

The psycho-hormonal influence of anaerobic fatigue on semi-professional female soccer players.

Globally it is assumed that high-intensity activities are the general cause of fatigue experienced during a soccer match. However, little is known about the hormonal and psychological effects of fatigue due to these activities on semi-professional female soccer players. Forty-seven female players (22.

The use of anthropometric measurements and the influence of demographic factors on the prediction of VO(2max) in a cohort of adolescents: the PAHL study.

Background: [Formula: see text] prediction models have not focused on children and adolescents from South Africa and have not included various demographic factors as possible predictors.

Aim: The purpose of this study was, therefore, to determine whether a valid [Formula: see text] prediction function can be developed from several anthropometric measurements and demographic factors of a cohort of adolescents in South Africa.

Subjects And Methods: A total of 214 adolescent boys (n = 88) and girls (n = 126) (15.

Changes in selected physical, motor performance and anthropometric components of university-level rugby players after one microcycle of a combined rugby conditioning and plyometric training program.

The purpose of this study was to determine the effects of a microcycle (4 weeks) combined rugby conditioning plyometric compared with a nonplyometric rugby conditioning program on selected physical and motor performance components and anthropometric measurements of university-level rugby players. Players (18.94 ± 0.
