Purpose:

To examine differences in oxygenation kinetics in the nondominant and dominant flexor digitorum profundus (FDP) of rock climbers.

Methods:

Participants were 28 sport climbers with a range of on-site abilities (6a+ to 8a French Sport). Using near-infrared spectroscopy, oxygenation kinetics of the FDP was assessed by calculating the time to half recovery (t 1/2 recovery) of the tissue-saturation index (TSI) after 3–5 min of ischemia.

Results:

A 2-way mixed-model ANOVA found a nonsignificant interaction (P = .112) for TSI by sex. However, there was a significant main effect (P = .027) of handedness (dominant vs nondominant FDP). The dominant forearm recovered 13.6% faster (t 1/2 recovery mean difference = 1.12 s, 95% CI 0.13–2.10 s) than the nondominant FDP. This was not affected by 6-mo on-site climbing ability or sex (P = .839, P = .683).

Conclusions:

Significant intraindividual differences in oxygenation kinetics of the FDP were found. Improvements in oxygenation kinetics in the FDP are likely due to the abilities of the muscle to deliver, perfuse, and consume oxygen. These enhancements may be due to structural adaptations in the microvasculature, such as an increase in capillary density and enhanced improvement in capillary filtration.

Rock climbing has been traditionally defined as a “masculine” sport (Young, 1997). The experiences of women in this sport have rarely been studied. The purpose of this study was to investigate the experiences of high-level female rock climbers. Qualitative analysis of interviews with eight high-level female climbers (ages 19 to 30 years) revealed three general themes: (a) compliance to hegemonic gender norms, (b) questioning hegemonic gender norms, and (c) resisting hegemonic gender norms. A discussion and analysis of these themes suggests that these female rock climbers engaged in a process of negotiated resistance as they attained a climbing identity, gained acceptance into the climbing subculture, and increased performance in the sport of rock climbing.

Although it has generated much theorizing (Csikszentmihalyi, 1975; Ellis, 1973; Harris, 1980; Mitchell, 1983), the phenomenon of stress-seeking behavior, as demonstrated in regular long-term involvement in the high-risk sports, has not been researched widely. In an attempt to go beyond the prevalent but simplistic "exhilaration' ' type of explanation for stress-seeking, this study examined the phenomenon in terms of the psychological characteristics associated with successful long-term involvement in the risk sport of rock climbing. Four behavioral characteristics were assessed: sensation seeking (SS), defined as "the need for varied, novel and complex sensations and experiences and the willingness to undertake physical and social risks for the sake of such experiences" (Zuckerman, 1979, p. 10); trait anxiety (TA), which refers to relatively stable individual differences in anxiety proneness (Spielberger, Gorsuch, & Lushene, 1970); need for achievement (NAch), which relates to the determinants of direction, magnitude, and persistence of behavior when the individual knows that his or her performance will be evaluated (Atkinson, 1964); and affiliation (AFF), which refers to the tendency to seek out, attain, and maintain a social bond with other people (Alderman, 1974).

Background:

There is more demand than ever for schools to equip children with the necessary skills to be physically active. The purpose of the Environmental Perceptions Investigation of Children’s Physical Activity (EPIC-PA) study was to investigate elementary and secondary school children’s perceptions to enhance the school physical activity environment.

Methods:

Four Australian government schools (2 elementary and 2 secondary) were recruited for the EPIC-PA study. During the study, 78 children were recruited aged 10 to 13 years. The focus group discussions consisted of 54 children (32 elementary and 22 secondary) and the map drawing sessions included 24 children (17 elementary and 7 secondary).

Results:

The findings from the EPIC-PA study revealed insight into uniquely desired features to encourage physical activity such as adventure physical activity facilities (eg, rock climbing walls), recreational physical activity facilities (eg, jumping pillows), physical activity excursions, animal activity programs and teacher-directed activities. In addition to specific features, childrens revealed a host of policies for equipment borrowing, access to sports equipment/areas, music during physical activity time and external physical education lessons.

Conclusions:

Understanding the multiple suggestions from children of features to enhance physical activity can be used by schools and researchers to create environments conducive to physical activity participation.

Traditional treadmill or bicycle ergometry neglects the upper-body musculature that predominantly limits or terminates rock-climbing performance (ie, the inability to continually pull up one’s body mass or “hang on”).

Purpose:

To develop an incremental maximal upper-body ergometer test (UBT) to evaluate climbers’ aerobic fitness and sport-specific work capacity and to compare these results with a traditional treadmill protocol.

Methods:

Eleven elite sport climbers (best redpoint grade Fr.8b) performed a UBT on a vertically mounted rowing ergometer and, on a separate occasion, performed a maximal incremental treadmill test (TMT). Cardiorespiratory parameters were measured continuously. Lactate (La) samples were collected.

Results:

Peak oxygen consumption (VO2peak) and heart rate in UBT and TMT were 34.1 ± 4.1 vs 58.3 ± 2.6 mL · min−1 · kg−1 and 185 ± 8 vs 197 ± 8 beats/min, respectively, and both variables were of significantly lower magnitude during UBT (P < .001). End-of-test La levels for UBT (11.9 ± 1.7 mmol/L) and TMT (12.3 ± 2.5 mmol/L) were similar (P = .554). Treadmill VO2peak was not correlated with either upper-body (UB) VO2peak (P = .854) or redpoint and on-sight climbing grade ability (P > .05). UB VO2peak and peak power output per kg body mass were both strongly correlated (P < .05) with climbing grade ability. The highest correlation coefficient was calculated between current on-sight grade and UB VO2peak (r = .85, P = .001).

Conclusion:

UBT aerobic- and work-capacity results were strongly correlated to climbing-performance variables and reflected sport-specific fatigue, and TMT results were not. UBT is preferred to TMT to test and monitor dedicated and elite rock climbers’ training status.

supplementation on serum T, calculated free T [cFT], and other biomarkers of the HPG-axis (i.e., LH, sex-hormone binding goblin [SHBG]) in male climbers. Rock climbing can activate the HPG-axis ( Sherk et al., 2011 ), and thus it may present one pathway for training adaptation in this sport. A standard protocol
