This study aimed to examine the effects of 6 weeks of high-intensity interval training (HIIT) vs. 6 weeks of on-court tennis training (OTT) on the psychophysiological responses, performance responses, and technical scores of young tennis players. Twenty-nine young male tennis players (aged 13.8 ± 0.4 years) were divided into HIIT (n = 14) and OTT …

This study evaluated the effectiveness of a tennis-specific training program on improving neuromuscular indices in competitive junior players. Tennis is a demanding sport because it requires speed, agility, explosive power, and aerobic conditioning along with the ability to react and anticipate quickly, and there are limited studies that evaluate these indices in young players after …

The aim of this study was to analyze the effects of a 5-week neuromuscular training (NMT) implemented before or after a tennis session in prepubertal players on selected components of physical fitness. Sixteen high-level tennis players with a mean age of 12.9 ± 0.4 years participated in this study, and were assigned to either a …

Among high school and collegiate football players, research shows that 56% of football players are considered obese. Training during a season involves rigorous cardio and strength conditioning to physically prepare for the necessary sport skills. While a preseason physical exam is required, minimal health information is gathered post season.  PURPOSE: The purpose of this pilot …

Abstract: Human, but not canine or equine running performance, is significantly stratified by sex. The degree of stratification has obvious implications for classification and regulation in athletics. However, whether the widely cited sex difference of 10-12% applies equally to sprint and endurance running events is unknown. Here, different determining factors for sprint (ground force/body mass) …

ABSTRACT BACKGROUND: We examined the kinetic and kinematic variables and postural characteristics of horizontal, inclined, and declined maximum sprint running.METHODS: Ten physically active men performed two maximal sprints at each condition (0% [0°]; ±5% [2.86°]; ±10% [5.71°]).RESULTS: During the +10% condition, the ankle was significantly more plantar-flexed (P<0.05) during the swing phase and the knee …

Abrupt changes in kinematics during sprint acceleration called transitions have previously been observed. This study aimed to examine whether ground reaction force (GRF) variables during sprint acceleration also show specific features of the transitions. Twenty-one male sprinters performed 60-m sprints, during which GRF data were recorded. Step-to-step spatio-temporal and GRF variables were approximated using an …

Simple Summary: Calf muscles, including the gastrocnemius and soleus muscles, are very important for soccer players, but the benefits of soleus stretching are rarely reported. Both regular and soleus stretching conditions lead to better ankle range of motion, maximum plantar flexion strength, dynamic balance and speed performances compared to the no-stretching control. Adding soleus stretches …

Abstract: The objective of this study was to characterize the mechanics of maximal running sprint acceleration in high-level athletes. Four elite (100-m best time 9.95-10.29 s) and five sub-elite (10.40-10.60 s) sprinters performed seven sprints in overground conditions. A single virtual 40-m sprint was reconstructed and kinetics parameters were calculated for each step using a …

Abstract: We aimed to clarify the mechanical determinants of sprinting performance during acceleration and maximal speed phases of a single sprint, using ground reaction forces (GRFs). While 18 male athletes performed a 60-m sprint, GRF was measured at every step over a 50-m distance from the start. Variables during the entire acceleration phase were approximated …
