Squash is an indoor game that is the second fastest racket sports if compared to badminton and tennis. Squash game puts a high demand on physical fitness of elite players which requires a quick development of high force, rapid changes of direction and fast reaction. The objective of this study was to develop the physical fitness profile of Malaysian junior state squash players. Sixty five 10 to 18 years old male Kelantan state squash players were tested with seven skill-related fitness tests. SPSS version 20.0 was used to analyze the data collected from the tests. A one-way ANOVA was used to detect statistical differences between groups. A posthoc test (LSD) was performed to determine differences in in the variables between groups. The data was collected for flexibility, speed, muscular endurance, power of upper and lower extremities, agility and cardiovascular endurance. There were significant differences in the mean speed, muscular endurance, agility, power of lower extremities, power of upper extremities, flexibility and predicted VO2 max between 13-15 and 16-18 years of age groups when compared to 10-12 years old players (p

Journal of Sports Science and Physical Education 7(1): Received: 3 January 2018, Accepted: 10 February 2018 – Weightlifting is a sport that requires both dynamic strength and power. Until today, weightlifting coaches are still exploring different training modes in an attempt to enhance both muscular strength and power of the competitive weightlifters. Research has shown that the use of the “right” training method could further provide knowledge on such effect for competitive weightlifters (Storey & Smith, 2012). Thus, the aim of this study was to investigate the effects of using the complex training method (applicable to weightlifting) compared to traditional resistance training on muscular strength among male competitive (state level) weightlifters. Seventeen male competitive weightlifters were randomly assigned into 2 groups: experimental group (Complex Training; n = 9), and control group (Traditional Resistance Training; n = 8). All participants trained for 6 weeks (2 sessions per week) with the total training volume equated between both groups. Participants underwent pre-test and posttest including the anthropometric measurements (height, body weight, and body fat) and lower body strength (isokinetic strength test) parameters. The results showed that there was a significant increase from pre- to post-test in knee extension peak torque t(8) = -4.22; p = .003 and t(7) = -5.37; p = .001, and knee flexion peak torque t(8) = -5.98; p = .001 and t(7) = -4.20; p = .004 in experimental and control groups respectively. No significant difference (p > .05) was observed in knee extension peak torque (22.9 ± 16.3 versus 13.9 ± 7.3) and knee flexion peak torque (11.4 ± 5.7 versus 10.1 ± 6.8) improvements between the complex training group and control group respectively at post-test. In conclusion, the use of complex training method showed similar effects in enhancing muscular strength with traditional resistance training after 6 weeks of intervention.

BACKGROUND: The present study investigated the effects of a 2-week modified exponential taper on physiological adaptation and time trial performance among junior cyclists.
METHODS: Participants (N.=27) with the mean age of 16.95±0.8 years, height of 165.6±6.1 cm and weight of 54.19±8.1 kg were matched into either modified exponential taper (N.=7), normal exponential taper (N.=7), or control (N.=7) groups using their initial VO2max values. Both experimental groups followed a 12-week progressive endurance training program and subsequently, a 2-week tapering phase. A simulated 20-km time trial performance along with VO2max, power output, heart rate and rating of perceived exertion were measured at baseline, pre and post-taper. One way ANOVA was used to analyze the difference between groups before the start of the intervention while mixed factorial ANOVA was used to analyze the difference between groups across measurement sessions. When homogeneity assumption was violated, the Greenhouse-Geisser Value was used for the corrected values of the degrees of freedom for the within subject factor the analysis.
RESULTS: Significant interactions between experimental groups and testing sessions were found in VO2max (F=6.67, df=4, P<0.05), power output (F=5.02, df=4, P<0.05), heart rate (F=10.87, df=2.51, P<0.05) rating of perceived exertion (F=13.04, df=4, P<0.05) and 20KM time trial (F=4.64, df=2.63, P<0.05). Post-hoc analysis revealed that both types of taper exhibited positive effects compared to the non-taper condition in the measured performance markers at post-taper while no different were found between the two taper groups.
CONCLUSIONS: It was concluded that both taper protocols successfully inducing physiological adaptations among the junior cyclists by reducing the volume and maintaining the intensity of training.
